Reciprocating Compressor


Compression Systems Standard

The NEUMAN & ESSER process gas compressors are selected and designed in an optimized way to meet customers` individual requirements and specifications.

The result is a reliable and solid heavy duty reciprocating compressor unit with low life cycle costs. The basic design, according to the specifications in the 5th edition of API 618, handles all kinds of hydrogen mix gas and hydrocarbon gases in corrosive and toxic fractions even at high discharge pressures. 


Process Gas / API 618

NEUMAN & ESSER’s range of production comprises oil-free, water-cooled reciprocating compressors of V-type and vertical construction to cover following standard ranges:

  • Seismic

  • PET

  • CO2-recovery / extraction

  • CNG

  • Acetylene

  • Biomethane

LNG Compressors

Within the LNG process chain, NEUMAN & ESSER provides the right solutions for offshore as well as onshore use. NEA LNG BOG compressors, send-out compressors and fuelgas booster compressors for gas-power-plants achieve exceptional high efficiency.

NEUMAN & ESSER LNG compressors cover the major applications for handling LNG as well as for offshore and onshore plants within the LNG chain. In order to maintain the critical conditions within LNG tanks, non-lube NEA LNG BOG compressors are used to manage reliable and efficient boil-off of the liquid gas. Whereas send-out compressors constantly boost vaporized natural gas for all pipeline networks. NEA’s third product in this field, the LNG fuelgas booster compressor, delivers stabile and reliable pressure for high-efficient gas turbines power plants.

LNG BOG Compressor

  • Boil off gas (BOG) is directly supplied from LNG tanks

  • Inlet pressure 1.02 - 1.3 bar(a) (= BOG pressure)

  • Outlet pressure up to 11 bar(a)

  • Inlet temperature range: -160° to -130°C

Send-out Compressor

  • Sending-out vaporized LNG to pipelines

  • Outlet pressure range: approx. 20 to 110 bar(a)

  • Optional: inlet pressure = BOG pressure

  • Inlet temperature range: 20° to 40°C

LNG Fuelgas Compressor

  • Compressing a stabile pressure for supply gas at power plants 

  • Supporting specially high efficient fuel gas turbines 

  • Special design extend the operating hours and the reliability
