1. Understanding Reciprocating Compressors:

Reciprocating compressors are workhorses in the oil and gas industry, playing a pivotal role in the extraction, processing, and transportation of hydrocarbons. Unlike their centrifugal counterparts, reciprocating compressors utilize pistons to compress gas, making them ideal for high-pressure and low-volume applications.

2. Working Principle:

The principle behind reciprocating compressors is simple yet effective. Gas is drawn into the compressor cylinder during the suction stroke as the piston moves downwards. Subsequently, the piston moves upwards, compressing the gas within the cylinder, thus increasing its pressure. This compressed gas is then discharged for further processing or transportation.
