A natural gas liquids (NGL) recovery system and method for separating NGLs from a feed gas is provided. The method includes receiving the feed gas; increasing a pressure of the feed gas by running the feed gas through a compressor connected to a gas turbine; diverting part of the feed gas from an output of the compressor and feeding the diverted part to a dryer; drying the diverted part to remove water and produce a dry gas; expanding the dry gas in a turbo-expander; separating the expanded gas into the NGL and fuel gas; and providing the fuel gas to the gas turbine as fuel without contamination.

Natural gas liquids recovery device and method

A device ( ) for continuous regulation of the gas flow rate processed by a reciprocating compressor, wherein the reciprocating compressor has at least one first compression piston ( ), which is associated with a first cylinder ( ), and can create a pressure which is variable over a period of time, and a second piston ( ), which acts inside a second cylinder ( ), which is in free communication with the said first compression cylinder ( ), associated with the said first piston ( ), and which acts on an additional dead space ( ). The device includes a third fluid mechanics cylinder ( ), which moves the said piston ( ) of the dead space ( ), wherein the third fluid mechanics cylinder ( ) is activated by means of a compressed fluid, supplied by means of an independent hydraulic system ( ), in order to obtain continuous variation of the dead space ( ).
