Gas Applications
Industry Applications
Wittig design and manufacture air and gas compressors for the most demanding gas applications.
Wittig compressors are particularly suited for biogas upgrading, gas extraction and toxic gas handling.
Our proven technology has delivered reliable results in the gas sector for years.
Compressors are used to increase the pressure of gas or air by decreasing its volume. Gas compressors have many industrial uses across the oil, gas, mining, energy and chemical sectors, providing reliable pressure for a variety of applications.
Rotary vane gas compressors are a fantastic technology to choose for gas treatment and processing applications as they offer high energy savings with low operational costs - providing consistent and reliable efficiency.
Designed with safety in mind, all of our Wittig compressors are ATEX certified and deliver reliable pulsation-free compression.
Read more below about how Wittig’s unique design and engineering expertise delivers amazing benefits for specific industries:
Biogas upgrading
Various processes are used to upgrade biogas (PSA, HPWS, membranes, and others). Our compressors with a range of 3.5 to 15 bar (abs.) offer outstanding performance in these applications because of their low maintenance costs, high efficiency, and low operating costs.
Landfill gas extraction
Wittig rotary vane compressors offer volumetric flow rates between 60 and 3,000 m³/hr at maximum pressures of 15 bar (abs.).
Boosting Pressure for Cogen Power Plants, Gaseous-Fuel Engines, and Industrial Ovens
The Wittig oil lubricated L, RVA and RO compressors offer maximum performance for pressure boosting.
Their high safety standard is of vital importance with potential contamination through by-products.
Digester gas recirculation
In digester gas recirculation, the digester gas produced is recirculated in order to achieve ideal mixing and an ideal temperature distribution in the digester tank.
Digester gas recirculation is a classic application for our gas compressors L and RVA which operate in a range from 120 to 5,200 m³/hr at operating pressures of up to 3.5 bar (abs.).
Coal mine gas extraction
After coal mines are shut down, coal mine gas and methane gas continue to escape to the earth's surface for decades. These gases can be captured and transported away effectively using Wittig RO rotary vane compressors installed in mobile container solutions.
Hydrogen compression
High purity hydrogen (99.99 %) is used in many industrial processes. This hydrogen is transported safely and very efficiently using Wittig rotary vane compressors at up to 11 bar (abs.). The strict ATEX requirements IIC gas are met without difficulty by their intrinsically safe design.
Butadiene
The compression of highly toxic gases requires special solutions. We manufacture customer-specific systems for these applications based on our long and extensive experience. The focus is on high safety and simplicity of operation. The special sealing systems used in our RO compressors meet the specific requirements of our customers.
Compression of Flare Gas in Refineries
As a standard practice at Wittig, a team of experts checks and analyzes whether it is possible to compress flare gases and higher molecular weight hydrocarbon gases (also mixed), and how high the compression can be. If it is technically feasible we provide extremely durable, low maintenance rotary vane compressors.
Synthesis gases
Synthesis gases are gaseous mixtures that mainly consist of nitrogen, carbon monoxide, and hydrogen. When it comes to selecting the right compressor, we can draw on years of experience in the area. Because of their cost efficiency, our rugged RO circulating oil-lubricated rotary vane compressors are ideal for this application, particularly for low pressure applications.
Wellhead compression
Wellhead compression is the compression of gases deposited in the earth directly at the wellhead. The unique problem with this application is that the suction-side conditions, for example the inlet pressure and volumetric flow, change during operation. Our circulating oil-lubricated compressors (rotary vane pump type RO) are the optimal machines for compressing gases when inlet pressures and volumetric flows are changing due to the nature of the process. Our customers are particularly interested in the ratio of costs (operating costs associated with compressors) to gas yield (efficiency).
Volatile Organic Compounds (VOC)
Volatile organic compounds are referred to as VOCs.They occur when producing, storing or loading and unloading crude oil. Our RO and RVA gas compressors are used to to compress these gases. Highly complex multiple technical and legal specifications, norms and laws must be met, especially when the installation is offshore - a challenge for both manufacturer and operator.
Boil-off gases (BOG)
Liquid Natural Gas produces vapors when stored, loaded and unloaded. For safety reasons they must be compressed. The Wittig RO compressors have been used here for some time now and have proven their reliability. Multiple technical and legal norms and specifications especially for offshore and marine applications are challenging for manufacturer and operator. Cruise ships and tankers are typical examples.
