A gas conditioning system is described herein. The system includes a slug catcher configured to separate a hydrocarbon feed stream into a liquid stream and a gas stream, and a first hydrate inhibitor injection unit configured to lower a hydrate formation temperature of the gas stream using a first hydrate inhibitor. The system includes a pressure reduction unit, a first separation unit configured to remove a first liquid stream including the first hydrate inhibitor from the gas stream, a mercury removal unit, and an acid gas removal unit. The system also includes a second hydrate inhibitor injection unit configured to further lower the hydrate formation temperature of the gas stream using a second hydrate inhibitor, a cooling unit, a second separation unit configured to remove a second liquid stream including the second hydrate inhibitor from the gas stream, and a dehydration unit configured to produce a final treated gas stream.

Efficiency of a gas conditioning system via hydrate inhibitor injection

A system and method for processing natural gas to produce liquefied natural gas is disclosed. The natural gas is cooled in one or more heat exchangers using a first refrigerant from a first refrigerant circuit in which the first refrigerant is compressed in a first compressor driven by a first gas turbine having a first inlet air stream. The natural gas is liquefied using a second refrigerant, the second refrigerant being compressed in a second compressor driven by a second gas turbine having a second inlet air stream. At least one of the inlet air streams is chilled from about the respective dry bulb temperature to a temperature below the respective wet bulb temperature. Water contained in at least one of the chilled first and second air streams is condensed and separated therefrom. At least a portion of the first refrigerant is condensed or sub-cooled using the separated water.
