Fundamentals of CH4 Compressor Fundamentals

Types of CH4 Compressors

There are various types of compressors used to compress CH4 gas. The most widely-used models include reciprocating and centrifugal compressors. Reciprocating compressors use positive displacement pistons while centrifugal compressors employ rotating impellers to compress it.

Principles of Operation

Reciprocating compressors work by drawing in gas on the intake stroke and compressing it on the compression stroke before discharging it out through their discharge port. Reciprocating compressors are typically used for low flow rates with high-pressure applications.

Centrifugal compressors use a rotating impeller to accelerate gas to high velocities before passing it through a diffuser to be converted to pressure energy by pressure differential. Centrifugal compressors are typically utilized for high flow rates with lower pressure requirements.

Both types of compressors can be used to compress CH4 gas. Your choice will depend on your application needs; reciprocating compressors tend to be more efficient at low flow rates while centrifugal ones offer greater performance at high flow rates.

CH4 compressors are used to compress CH4 gas and are available in multiple varieties – reciprocating compressors and centrifugal compressors are two common types. Your choice will ultimately depend upon your application requirements.
