Gas plants, also known as Gas Liquids Recovery Units are primarily used to recover saleable hydrocarbon liquids from gas streams and to control sales gas BTU content (Dewpoint Control Units). Side benefits of these units are eliminating the condensation and the two-phase flow in transmission pipelines and providing gas with a consistent heating value for fuel to compression and combustion turbines.

The simplest form of liquid recovery units utilizes heat exchangers and an external refrigeration system to cool the gas and separate the hydrocarbon liquids. The separated gas is cross exchanged with the inlet gas for initial cooling. The separated liquid is level controlled to a stabilizer where the temperature and pressure is controlled to produce a specified vapor pressure product.   

QBJ units are designed and engineered to use mechanical refrigeration, J-T refrigeration and our proprietary mixed refrigerant system.
