Mads Nipper to lead industry’s climate efforts



Grundfos CEO has been appointed chairman of the Danish government’s climate partnership for production companies. He will fight to promote visionary solutions for the benefit of all.

The government has an ambitious goal for Denmark to reduce its emission of greenhouse gasses by 70 percent compared to 1990 by 2030. This should be possible with the help of 13 climate partnerships presented at Marienborg on Wednesday afternoon. At the same time, Mads Nipper was introduced as chairman of the climate partnership for production companies.

On the right track

The sector having Mads Nipper as chairman includes all production except from the food, concrete and brick industries. Industry has Denmark’s third largest potential for reducing greenhouse gas emissions only surpassed by agriculture and transport.

“Since 1990, greenhouse gas emissions from production companies have halved in Denmark. This is a trend, we must carry on – we just have to be more ambitious. We must put even higher demands on ourselves, dare to take the lead and develop long-term solutions,” says Mads Nipper and continues:

“We must be visionary and create innovative solutions for the benefit of all, and this is only possible if the government, industry, the sectors and the two sides of industry work together. At the same time, we must ensure the involvement of companies as well as trade unions and other stakeholders”.

Several Danish companies already make products and solutions, which contribute to reducing the energy consumption and C02 emission, and Mads Nipper will work to promote them both in Denmark and abroad. In this way, Danish industry can also help encourage the global efforts for the climate.

Natural social responsibility

Mads Nipper himself represents a company that makes a significant difference to the climate with its energy efficient products and solutions, and the company has a tradition of taking responsibility in relation to the rest of the society. Therefore, it is perfectly natural for him to accept the new task as chairman of the government’s climate partnership for production companies.

“As companies, we are part of society, and as a result the challenges of Denmark are also our challenges. Through a broad collaboration with politicians, the business community and the trade union movement, we can develop green solutions that are socially balanced, and which can secure future work places, welfare and prosperity,” says Mads Nipper.

As chairman of the climate partnership for production companies, it is his responsibility to make a roadmap that will show the way for the sector’s C02 reductions towards 2030.

Ready-made pump stations help Philippines’ growing water issues



A speedy implementation process makes for a helping hand as the Philippines’ need for water management increases.

Around seven million people in The Philippines rely on unsafe and unsustainable water sources. Over three times as many lack access to proper sanitation. The government of the country has accordingly geared up to address these issues by 2028, and here reliable and intelligent technology will play a critical role.

Grundfos Philippines has launched a turn-key solution, the Prefabricated Pumping Stations (PPS), to help meet the country’s growing flood and wastewater management needs.

In effect, the PPS has already shown itself an ideal solution for wasterwater management for tourist destinations and hotels in Lio, a tourism estate in the Philippine province of Palawan.

Benson Cruz, Technical Services Head of the local wastewater facilities in the Lio Estate, says: “We seek to constantly raise the bar for sustainable tourism. Therefore our obvious choice was Grundfos’ Prefabricated Pumping Stations as it helps us decrease not only our overall environmental footprint but the project cost as well”.

As the name reveals the PPS has already been constructed when it arrives at the site of implementation. “Opposed to traditional pumping stations the PPS is sent to the site as a complete package, making installation easier and usually completed within 24 hours,” Jonathan Breton, General Manager, Grundfos Philippines explains. This reduces installation time by as much as 80%, ensuring minimal disruption to people and infrastructure.

Using technology to improve performance



Expanders and high energy pumps involved in the hydrocarbon industry face many challenges; from the evolution of operating conditions to corrosive media and rising operating costs over their life span. Advances in manufacturing, repair and monitoring technology are enabling operators to mitigate these effects and prolong the effective service life of this important equipment.

Charles Soothill, Head of Technology for the service division, at Sulzer looks at some of the recent advances in rotating equipment technology and how they can be implemented to improve performance and minimize costs.

Everyday we all use products from the hydrocarbon industry; fuel for the commute to work, gas to cook dinner or the plastics used to make casings for our electronics. This industry is closely linked to our lives and so any improvements that reduce operating costs will ultimately benefit us, the end users.

High energy pumps and expanders play a vital role in the hydrocarbon sector and each has its own challenges. Efficiency is essential in both applications to ensure the optimum use of energy, which is one of the biggest operating costs in the industry. With continuous operation, detrimental processes, such as erosion and corrosion, take a significant toll on the vane tolerances, seals and impeller clearances. Without timely intervention, these can lead to considerable losses.


Typically, large pumps are designed for an extended service life, however, when the performance does begin to deteriorate, it is often a sign that the volute or the impeller has become worn or corroded. Having, in many cases, provided decades of reliable service, finding new parts can be a challenge that, even if successful, can mean a long lead time before delivery. Fortunately, the latest in design technology and manufacturing processes can significantly reduce the time and the cost involved in creating replacement parts.

In situations where original equipment manufacturers (OEMs) are able to create parts for legacy machines, this service may have a delay as a special build could be necessary. The OEM advantage here is the availability of original drawings for the parts, however, reassigning production equipment to a one-off project can incur additional costs as well as a delay in delivery, unless an alternative process is available.

Fortunately, modern technology offers a solution that can be implemented by both OEMs, repairers and specialist parts suppliers. The advent of reverse engineering using sophisticated coordinate measuring machines, 3D solid modeling software and laser scanning makes it possible to recreate complex parts on short lead times.

Pump modernization and rerating

The advances in design technology have been matched by similar developments in materials science that together enable original designs to be upgraded. Older pumps manufactured using materials such as bronze and cast iron, which cannot be welded, can have their service lives extended using stainless steel or other advanced alloys.  

In many cases, the original operating conditions for which the pump was designed will have evolved since first commissioning of the pump. Such changes can lead to a reduction in both performance and efficiency, but these can be addressed during a major repair or overhaul.   

When creating a new impeller, the hydraulic design can be re-optimized to the operating conditions – very often this will reduce energy requirements and lead to significant reductions in operational costs. Using the latest design software and computational fluid dynamics (CFD), reverse engineered components can be fine-tuned to deliver optimal hydraulic performance.  

Manufacturing developments

The time required to create new components for high value assets such as high energy pumps and expanders has been significantly reduced recently with the advent of hybrid manufacturing equipment. Processes such as laser metal deposition and five-axis milling can be carried out on a single machine, allowing for rapid production.

For example, an impeller can be created from a forged core that is machined using 5-axis methods to establish the basic shape. Then, a laser melts a stream of powder and deposits a layer of new metal onto the surface. This allows a large volume of material to be built-up quickly. The hard surface can then be machined to the final dimensions, all on the same machine.

The flexibility of this manufacturing method also offers the potential to create components using different materials, allowing specific alloys to be used in different areas of the design. This is an extension of existing technologies such as specialist coatings and hard-facings where optimized material properties can be incorporated into the design during the manufacturing process, rather than as an additional process.  

Enhancing pump design

In situations where a revised pump asset is required, operators can take advantage of all the latest design and manufacturing technology to deliver a pump that is optimized for the application. Energy consumption, which is a key component in operational costs, can be reduced by focusing on pump efficiency and minimizing all possible losses in the system.

By gaining a complete understanding of the application, fluid characteristics and flow demands, the most appropriate pump technology that will deliver premium efficiency can be selected. Matching the pump construction with the optimum impeller design will result in the most cost-effective solution, both in terms of initial capital investment and long-term operating costs.

Further gains can be achieved through correct sizing of the pump to avoid energy wastage. This may appear an obvious statement but oversizing often occurs as a result of multiple safety factors being added to the required head and flow values. As a result, the oversized pump does not run within its optimum efficiency curve during normal production.

Using data to optimize pump performance

Having achieved the best possible design for an application, it is important to maintain the best performance and ensure that maintenance is undertaken at the most opportune time. Today, advanced analytics can be used to capture and process existing pump data to deliver considerable savings in both operating and maintenance costs.

By highlighting underperforming assets, it is possible to implement a proactive maintenance strategy and justify investment recommendations; carefully timing these to minimize lost production. Using data on performance, reliability and efficiency enables operators to determine the ability of the system to meet key performance indicators (KPIs).

Increased pump availability can have a significant effect on revenue by ensuring productivity is better maintained. Further benefits can be achieved through reduced maintenance spending by employing resources when they are needed rather than on a preset schedule.

Refining raw data

A digital system created by Sulzer, called BLUE BOX™ makes use of data for pressure, flow, density, viscosity and power consumption. Together with information for the maintenance department including vibration and asset temperature readings, analytical tools generate visualizations in near real-time for the stakeholders in the management and maintenance of the system.

The data is extracted directly from a variety of sources such as supervisory control and data acquisition (SCADA), programmable logic controllers (PLCs), process historians, databases, sensors and instrumentation. At this point, an industrial-grade computer can be installed to process the data – known as an edge device it is equipped with firewalls that provide a secure connection to the internet.

Customer data is processed in a cloud server using a secure file transfer protocol (SFTP). Using proven algorithms, the data is analyzed against known performance curves and displayed in a custom interface that offers the operator the greatest benefit. This cloud-based solution simplifies regulatory compliance with a minimal IT footprint and is designed to be easily scalable to suit a wide range of operations.


In common with high-energy pumps, expanders are high-value assets that are relied upon for continuous, efficient operation. Any downtime has significant operational consequences, so it needs to be kept to an absolute minimum. Therefore, improving efficiency and reliability as well as reducing unscheduled repairs are important goals for the maintenance team.

Every expander contains a rotor which operates at high rotational speeds and pressures, it may also be required to endure high temperatures and corrosive media. To keep such an important asset operational and reliable, the use of performance data from predictive maintenance instrumentation can make a decisive difference in availability and the total cost of ownership (TCO) over its lifetime.

During planned shut-down periods, detailed inspection reports can highlight improvements to an expander that will improve life cycle costs (LCC), process efficiency and productivity. Depending on the findings, several modern maintenance and repair techniques can be used to address specific issues.

Modern coating technology can now be applied to legacy equipment that was not designed to take account of particulate-laden gas streams for example. In this way, the original surfaces can be restored and upgraded to offer greatly improved anti-fouling and corrosion resistance.

Optimized efficiency

The stationary section of an expander consists of many precision parts that sit in close proximity to the rotating parts to achieve high levels of efficiency. Some of these components will benefit from being upgraded and manufactured from robust alloys, such as Hastelloy X, which offer improved durability in high temperature environments.

The thickness of the casing itself can be increased, which makes the component more robust and less prone to heat distortion over time. This improvement can often be coupled with an abradable coating on the stator inner surface that provides increased clearance control with the rotor blades. This area is crucial in optimizing the efficiency of the expander since tip leakage accounts for substantial efficiency losses in legacy equipment.

At the same time, the rotor blades can also be upgraded to take advantage of modern alloys that are designed for applications where high strength and good corrosion resistance at temperatures up to 700 °C (1’300 °F) are required. Together with revised stator segments that offer improved dimensional control, it is possible to implement a range of improvements that increase efficiency and therefore productivity.

In addition to axial hot gas expanders used in Nitric Acid and FCC (Fluid Catalytic Cracking) applications Sulzer also uses these repair technologies for radial in-flow expanders used in various cryogenic applications such as Liquefied Natural Gas (LNG) production, Natural Gas Liquids (NGL) recovery, Dew-point Control (DPC), Ethylene recovery and Industrial gases.

Component upgrades

Some specific changes applicable to axial hot gas expanders include replacing expander disk retention bolts with a different grade of steel. Multiple expander disks, when held together on the rotor by a bolt that passes through their centers can be upgraded. The original bolt is usually machined from 422 stainless steel and is subjected to considerable heat stress. This component can be upgraded to a custom 450 stainless steel alloy that allows increased bolt stretch, resulting in greater “bundle” crush on the rotor assembly.

The same upgrade principle can be applied to the rotor support bearings. Running at such high speeds, it is important that the bearings can withstand operational stresses to deliver long-term reliability. Cylindrical sleeve bearings can be upgraded to tilt pad bearings, while spherical seated bearings can be replaced with cylindrical seated bearings, which provide better performance and will help to reduce maintenance costs in the future.   FCC expanders frequently experience wear on the blades caused by catalyst particles in the flue gas. The catalyst tends to build-up solid deposits on the leading edges and tips of the blades, which can cause vibrational issues and exacerbate the problem. Typically, the worn blades are simply replaced; however, with its experience repairing gas turbine blades (which operate at temperatures up to 1100dgrC), Sulzer can reduce costs by repairing FCC expander blades (which typically operate at lower temperatures – up to 700dgrC).   These improvements have been made possible via new materials and repair technologies. By working with an experienced independent maintenance provider, or a similarly equipped OEM (Sulzer happens to be both) to assess the condition of important assets, it is possible to prioritize any upgrade projects and justify the supporting investment decisions. In taking advantage of new technologies, operators in the hydrocarbon sector can reduce operating costs through improved reliability, efficiency and performance.

ABB’s new Baldor-Reliance® EC Titanium™ for pump, fan and compressed air systems



Globally, demand for electricity will grow faster than for any other form of final energy. Thus, emissions will keep rising, unless we start doing something different.

This global electricity demand growth is expected to double by 2040.  With electric motors consuming an estimated 1/3 of the world’s electricity… that number is expected to be the equivalent to adding an electricity market the size of China.

Source: IEA WEO 2017

In the US, as example, the applications which are the primary consumers of electricity are pump, fan and compressed air systems. There is heightened focus on improving system efficiency for these particular applications because most installations run at partial speed and reduced load ranges.  Equipment manufacturers are seeking IE5 efficiencies over a wide speed and load range – not just at peak operating conditions. New legislation will require overall equipment designs to achieve high efficiencies at multiple points across their operating range.

Source: US DOE Energy Footprints 2015

Motor standards have been in place for decades, yet there is a growing demand to achieve greater efficiencies as regulations continue to tighten on the total design of fans, pumps and compressed air packages. Equipment manufacturers are turning to new motor technologies to achieve the highest system efficiency possible from wire to air while using sustainable materials.

Introducing the Baldor-Reliance® EC Titanium  integrated motor-drive.  Our solution incorporates permanent magnet rotor technology to achieve IE5+ (NEMA Ultra-Premium) efficiency at rated design while maintaining performance across varying speeds and load conditions. Equipment incorporating this technology can therefore achieve optimal performance no matter the operating point.

This highly efficient integrated motor drive is a step above traditional EC motor designs and delivers up to 16% efficiency gains compared to IE3 or NEMA Premium efficient motors.  The EC Titanium is paired with an electronic drive control that enables the use of advanced motor control algorithms for higher efficiencies across the speed load range than traditional EC (electrically commutated) motor solutions. By utilizing a drive to control motors, up to 40% energy savings are achieved.
