Gas Compression

Gas Compression packages are used for gathering and transporting natural gas from production areas downstream where it can be further processed and refined. Spitzer Industries has over twenty years’ experience packaging reciprocating compression for the oil and gas industry. Our packages are driven by either gas-fueled reciprocating engines or variable speed electric motors, whichever is better suited to your facility needs. Spitzer Industries provides fully integrated modular compressor to facilitate ease of reassembly upon delivery.

Main Features of Spitzer Gas Compression Packages

  • Spitzer Industries manufactures reciprocating gas and electric motor driven units from 90 hp to over 5,000 hp.
  • Spitzer Industries offers a standard line of products using Caterpillar, Waukesha, and Ariel OEM components from 200 hp to 2500 hp.
  • Spitzer Industries allows you to purchase a fully customized unit, a standard package, or work with our engineers to modify our standard into your standard.
  • Spitzer Industries has over 20 years of Gas Compression unit design and fabrication experience packaging over 2,500,000 HP of reciprocating gas compression packages.
  • All Spitzer packages meet or exceed all relevant industry standards, including vibration and pulsation control in the compressor, vessels, piping, cooler, scrubbers, and exhaust system.

Standard Packages

Spitzer Standard Gas Compression units are designed for 1, 2 or 3-stage reciprocating gas compression using Caterpillar and Ariel OEM components. The standard gas compressor package can be modified to meet the client’s specifications, if needed.

Our engineers will review your process conditions to determine if one of our standard packages will work for your application.

  • All compressor packages are designed for discharge pressure and temperature of 1440 / 1650 PSIG and 350 °F respectively
  • All compressor units are packaged on a heavy-duty steel skid suitable for mounting on a compacted gravel pad, piles or an engineered concrete foundation
  • A Suction Scrubber for each stage of compression is equipped with a wire mesh pad to remove trace liquid droplets from the gas stream to protect downstream equipment from damage
  • An Air-cooled heat exchanger provides cooler for engine utilities and process gas (each stage) that can be either motor or engine driven
  • Exhaust system to provide noise reduction (25-30 dB) and catalyst housing for emissions reduction
  • Fully integrated utility systems with customer connections provided at skid edge (Compressor and Engine Lube Oil, Fuel Gas, Auxiliary Water)
  • On-skid PLC for process monitoring and automated shutdown controls
  • API 618 5th Addition DA2 (M2-M4) Acoustical/Pulsation Analysis (Recommended Option for any new configurations)

  • Integration into modular Spitzer Industries Modular Compressor Stations

Process Description

The Spitzer Standard compressor unit is a 4-throw, 3-stage reciprocating compressor package. Each stage of compression operates in the same systematic way. The process gas will enter the Suction Scrubber where any liquids will be removed prior to compression. The gas will then flow through an engineered pulsation bottle before entering the compressor cylinder(s). After compression, the gas passes through a discharge pulsation bottle to dampen gas pulsations before travelling through an aftercooler to remove the heat of compression. Cooling the gas may cause additional liquids to drop out based on the gas dew point. Inter-stage suction scrubbers knock out any produced liquids before the next stage of compression.
