Process Gas Compression & Processing

Wittig are the first choice for coke oven and process gas processing industries - where reliability and efficiency are critical requirements. For many decades, Wittig have and continue to design and manufacture an impressive range of high performance, long-lasting and reliable vacuum pumps and compressors, for both gas and air applications.

Wittig process gas compressors are suitable for a range or diverse gases including:

  • Hydrogen
  • Helium
  • Toxic gases
  • Syngas

Wittig process gas compressors for a diverse range of gases

Industry Leading Record for Safety & Reliability

The compression of Butadiene, Hydrogen and highly toxic or flammable gases is safe and reliable using Wittig gas compressors, we manufacture customer-specific systems for these applications based on our long and extensive experience.

The special sealing systems used in our RO compressors meet the specific requirements of our customers for these demanding gas compressor applications.

Flare Gas Recovery (FGR) is the process of recovering the waste gases that would normally be flared, so they can be used as fuel gas elsewhere in the facility.

The production of steel in blast furnaces results in a considerable amount of by-product gas (blast furnace gas, coke oven gas, basic oxygen furnace gas, etc.) that can be used as fuel to produce power or steam.

These gases can then be recovered, filtered and burned in adapted gas turbines so that a considerable amount of the energy used for the blast furnace blower can be recovered to generate electrical power and Wittig compressors are a safe and reliable part of this process.
