Glauber builds well-designed, reliable RNG (Renewable Natural Gas) skid systems to client specifications. We work with customers to develop the highest-quality skid systems that perform well no matter their environment, keeping clients from around the world returning to us again and again.
Our ability to meet specific, complicated, and demanding requirements means that we can install efficient systems in harsh conditions and tight spaces. Recently, we took our skills to Oahu, HI, where we built the region’s first RNG system.
Working in Oahu
To achieve Hawaii’s goal of reducing its reliance on nonrenewable energy sources, Hawaii Gas sought to install a custom RNG skid system for the Honolulu Wastewater Treatment plant. They needed a system that could meet the plant’s gas needs and resist the harsh saltwater conditions present there. Hawaii Gas set strict deadlines for the project, and they requested that our system be capable of easily integrating with other companies’ equipment and controls.
One of our biggest challenges was to create a feed compressor that not only did its job well but also fit smoothly into the membrane container. Doing all this within the client’s relatively short time frame also complicated matters.
Working with natural gas, especially in oceanic environments, creates unique challenges. Fortunately, our RNG skid solutions can adapt to constantly changing environmental conditions without sacrificing their ability to work efficiently.
We used marine-grade materials and components to build RNG skid systems able to resist the constant wear and tear the ocean places on them. Made from specially alloyed stainless and galvanized steel, marine-grade materials hold up to corrosive environments much more effectively than unprepared metals.
Our engineers built the compressor system, complete with fully automated controls, that fit the situation’s restrictive dimensions and that we could smoothly integrate into the wastewater plant’s other systems.
The Result? Client Success
The system’s heat exchanger network not only reduced overall chiller size requirements, but also made the system a great deal more energy efficient than if it had required full load external heating and cooling. Additionally, because we focused on sourcing the best marine-grade materials, Hawaii Gas will see fewer maintenance requirements. Not having to worry about the system breaking down and requiring costly repairs allows the company to dedicate resources to other important matters.
We completed the entire project by the demanding deadline. As soon as the system was in place, Hawaii Gas hosted a blessing ceremony, at which several Hawaii state dignitaries complimented us on our work. This case study is just one example of our commitment to providing customers with the best-functioning RNG skid systems their energy grids need.

Choosing the right type of pump for your fluid and air flow needs is an important decision. It requires knowing the difference between centrifugal and positive displacement pumps and how they impact your application.
Centrifugal pumps are the most popular type of pump in the world. They are effective, robust, and relatively easy to use. Positive displacement pumps are commonly utilized in high pressure hydraulic systems.
There are several key differences in the way these two types of pumps function and operate.
The mechanical component of centrifugal pumps imparts velocity to the liquid, resulting in a pressure at the outlet. The pressure changes as flow varies, which drives performance. Efficiency decreases as viscosity increases due to frictional losses inside the pump.
On the other hand, positive displacement pumps capture a confined amount of liquid and transfer it from the suction to the discharge port. Flow remains constant under changing pressure.
Their individual qualities make each type of pump ideal for separate uses.
Centrifugal pump applications include air conditioning, boiler feed, irrigation, light fuel transfer, petrochemical, sea water transfer, water circulation, and general water supply.
Positive displacement pump applications include fuel, dewatering, lubrication oils, waste oils, hydraulics, and mediums containing high levels of solids.

Renewable Natural Gas (RNG) is a type of biogas obtained from the decomposition of organic matter. The primary sources of RNG include landfills, animal waste, and solid waste recovered from wastewater treatment processes. Once captured, the gas is processed to remove unwanted components such as carbon dioxide, hydrogen sulfide, and water.
Raw extracted RNG must undergo several processes before it can be sold to the consumer. The equipment necessary for processing RNG is typically contained in structural frame systems known as skids. These skids can include individual or multiple processes depending on the needs of the consumer; Regardless, it is essential to custom-design each skid to suit a facility’s unique processing and spatial requirements.
Glauber Equipment Corporation, Inc. offers a variety of custom skid solutions that can be incorporated into various production systems for complete RNG processing.
The feed blower is one of the first components in a renewable natural gas processing system. Through the use of centrifugal or positive displacement Compressors, systems increase the pressure of the gas for further processing and compression.
Feed blower skids are almost always combined with dehydration skids for the removal of potentially damaging moisture from feedstock RNG.
Vacuum blowers are used in the CO2/methane membrane separation process. During renewable natural gas processing, CO2 must be removed from the feedstock to ensure the gas meets industry-specific requirements. The vacuum blower creates a negative pressure on the suction side and assists in the separation of CO2 through the membrane using the principle of selective permeation. Vacuum blowers and feed blowers are frequently used together and are usually integrated into a single skid.
Feed Gas Compressor
For separation of CO2 from the desired methane gas, the mixture must be compressed and processed through a series of selective membranes. To address this, a feed gas compressor skid uses rotary vane or screw mechanisms to “squeeze” the gas and create a buildup of pressure on the positive-pressure side of the membrane system. These skids may also consist of a knockout/moisture separator to protect the compressor and downstream equipment from corrosion and other moisture-related deterioration. Depending on the size of the compressor, pressure increases up to 350 psig may be achieved.
Sales Gas Compressor
The sales gas compression is the final stage of renewable natural gas processing. Here, the dry and purified “sales” gas is compressed to enable transportation through utility piping networks. Typically, reciprocating or screw mechanisms are used to compress the gas to the high pressures required at this stage.

At Glauber, we’re always excited when we have the opportunity to share industry expertise with our customers. To that end, we hosted our 2018 Wilden Pump Training—led by…
- Tom Zuckett: Wilden’s Northeast Regional Manager
- John Wallace: Sales Director – US & Canada.
The event had a great turnout, with more than 25 customers participating in the training session. Tom and John provided the group with an in-depth overview of Wilden pumps, complete with a demonstration of some of the leading products.
What Was Discussed
This year’s training session focused primarily on Wilden’s air operated double diaphragm (AODD) pumps, with ProFlo Shift Technology. These pumps feature a specialized patented design that incorporates the latest innovative technology to maximize the pump’s efficiency. Wilden’s AODD pumps, with ProFlo Shift Technology, increase overall productivity, reduce air and energy consumption, and require significantly less maintenance than many other AODD pump types.
During the training session, the group discussed a wide range of topics related to the AODD pumps, including:
Wilden AODD Pro-Flo®
- How AODD pumps work
- How AODD air motors work
- Best maintenance practices
- Best installation practices
- Best operational practices
- Troubleshooting and repair tips
After going over the main operational features of AODD pumps, John Wallace led the group in a demonstration of the two-inch Wilden pump, featuring Wilden’s ProFlo SHIFT technology. The exercise helped show customers how much Wilden’s ProFlo SHIFT technology can make a difference when it comes to energy savings––giving companies a huge advantage over competitors who may be using less efficient pumps
During this portion of the event, John demonstrated both the two-inch Wilden pump and a competing two-inch pump under the same system conditions – a flow rate of 80 gallons per minute; system head pressure of 15 psi; and the same pressure gauges, fluid flow meter, and air flow meter – to see how they’d perform against one another.
In the end, the results spoke for themselves—successfully showing how the Wilden pump outperforms the leading competing pump in energy savings. The demonstration revealed that the competitor’s pump consumed 39% more standard cubic feet per minute (SCFM) of air than the Wilden pump. Wilden consumed 32 SCFM of air while the competing pump consumed 52 SCFM of air.
The competing pump also exhibited 42% more strokes per minute (s/m) with 198 s/m compared to Wilden’s 116 s/m. Together, these results demonstrated the value of Wilden’s SHIFT technology and how it gives customers an edge over their competitors.
Overall the training was a great success, allowing customers to see firsthand how Wilden’s technology can save them valuable time and money. We enjoyed hosting all of our wonderful participants this year, and we hope to see them again soon at a future event. We also are very grateful to Tom Zuckett and John Wallace for sharing their expertise.
