Modern Turbo Compressors For High-Pressure Pipelines

September 2012, Vol. 239 No. 9

Old-fashioned high-pressure reciprocating compressors and oil-sealed heavy-bolted-head high-pressure centrifugal compressors have been used in high-pressure pipeline stations for decades. However, they seem unreliable, inefficient, heavy, bulky and wasteful. Modern high-pressure gas stations use vertically split, dry-gas-sealed, shear-ring head centrifugal compressors for high-pressure service.

Atlas Copco Compressors Inaugurates Houston Facility

June 2012 Vol. 239 No. 6

Atlas Copco Compressors Product Company has dedicated a new 96,000 square foot facility in Houston, housing customer relations for North and South America as well as producing a wide range of air compressors, dryers and skid packages. The new building brings together 150 employees from several Atlas Copco subsidiaries under one roof to create its largest office in the United States.

Protecting A Centrifugal Compressor From Surge

March 2012, Vol. 239 No. 3

Surge is defined as the operating point at which centrifugal compressor peak head capability and minimum flow limits are reached. Actually, the working principle of a centrifugal compressor is increasing the kinetic energy of the fluid with a rotating impeller. The fluid is then slowed down in a volume called the plenum, where the kinetic energy is converted into potential energy in form of a pressure rise.

Gas Management Solutions In Oil Production

September 2010 Vol. 237 No. 9

Oil production generally involves the processing of upstream fluids into a crude oil that meets certain specifications. This is typically done at a field processing facility and involves a number of operations in different processing systems within the facility. One primary function of this processing is “phase separation” to remove water, solids and gas from the produced fluid, thereby producing crude oil that meets the specifications and provides the main source of income for the operator.

An Emissions Solution On Two-Stroke Lean-Burn Engines

January 2010 Vol. 237 No. 1

The internal combustion engine (ICE) fueled by natural gas has moved in the direction of efficiency and environmental friendliness with lean-burn technology. Cameron’s AJAX®LE uses a CleanBurn™ prechamber type of combustion system that allows for operation with very stable combustion at lean air fuel mixtures.
