Types of Gas Compressors

  Types of Gas Compressors A compressor is a mechanical device that increases the pressure of a gas by reducing its volume or by imparting velocity on the gas.  This can be done in numerous different types of gas compressors.  Positive Displacement Compressors Positive displacement compressors are machines in which successive volumes of gas are … Continued

Benefits of Sliding Vane Gas Compressors

  Operation of the Sliding Vane Gas Compressor A sliding vane compressor is a positive displacement compressor, meaning it decreases a specific volume of a gas, resulting in increased gas pressure. The sliding vane compressor consists of an external casing called a cylinder, the rotating element inside called the rotor, and sliding vanes. The rotor … Continued

Why Direct Injection Compressor Lubrication Is the Best Choice Direct injection compressor lubrication is used in sliding vane gas compressors and has distinct benefits over other types of lubrication used by other compressors. In order to understand why, it’s necessary to understand how a sliding vane compressor works. Sliding Vane Compressor Design and Operation A … Continued

Compressing Gas Streams Containing H2S

  Sour gas is any gas containing significant amounts, typically above 20ppm, of hydrogen sulfide (H2S). H2S is a colorless gas that is heavier than air and harmful to humans at concentrations of 20 ppm in air. At concentrations of 800 ppm death results in 30 minutes due to destruction of lung tissues. At low … Continued

Common Rotary Equipment Tests and Analyses

Compressor testing can be utilized to validate expected performance, analyze product developments, determine baseline data in a controlled environment, troubleshoot unexpected or undesirable operation and much more. It is often preferable to hire an independent third-party testing service to ensure unbiased results. Popular and valuable tests that are commonly performed include: Performance Test -The purpose … Continued

Common Oil and Gas Industry Applications for Gas Compressors

Despite advances in renewable power sources, crude oil remains one of the most valuable natural commodities today. A “fossil fuel” created by the natural compression of ancient algae and plankton remains over millions of years, crude oil is harnessed by drilling into the ground and then refined and distilled to create a wide array of … Continued

Biogas Management: What you Need to Know

Biogas is a natural energy source made from the decomposition of biological matter. More simply put, when food, animal waste, plants, sewage, and other natural waste is broken down by bacteria, a gas is formed that includes methane. Scientists have determined that this byproduct, biogas, can be a useful source of energy. The process of … Continued

Vacuum Cooling for Food Processing

The International Trade Administration (ITA) estimates that nearly half of all food is lost before it ever reaches a consumer’s table. Much of this over $750 billion per year loss is due to problems in the cold chain—a regulated, temperature-controlled supply chain that is designed to ensure food safety and extend product life. Fortunately, vacuum … Continued
