Efficiency of a Gas Conditioning System via Hydrate Inhibitor Injection

A method for improving the efficiency of a gas conditioning system via hydrate inhibitor injection, comprising:

• separating a hydrocarbon feed stream into a liquid stream and a gas stream within a slug catcher;
• injecting a first hydrate inhibitor into the gas stream within a first hydrate inhibitor injection unit such that a hydrate formation temperature of the gas stream is altered from a first hydrate formation temperature to a second, lowered hydrate formation temperature;
• reducing a pressure of the gas stream within a pressure reduction unit;
• removing a first liquid stream comprising condensed water combined with the first hydrate inhibitor and condensed hydrocarbons from the gas stream within a first separation unit;
• removing mercury from the gas stream within a mercury removal unit;
• removing acid gases from the gas stream within an acid gas removal unit;
• injecting a second hydrate inhibitor into the gas stream within a second hydrate inhibitor injection unit such that the hydrate formation temperature of the gas stream is altered from a third hydrate formation temperature to a fourth, lowered hydrate formation temperature;
• reducing a temperature of the gas stream within a cooling unit;
• removing a second liquid stream comprising additional condensed water combined with the second hydrate inhibitor and additional condensed hydrocarbons from the gas stream within a second separation unit;
• and
• removing residual water from the gas stream within a dehydration unit, producing a final treated gas stream.

A method for injecting a hydrate inhibitor into a gas stream prior to reducing the pressure of the gas stream, comprising:

• separating a hydrocarbon feed stream into a liquid stream and a gas stream within a slug catcher;
• injecting a hydrate inhibitor into the gas stream within a hydrate inhibitor injection unit;
• mixing the hydrate inhibitor with the gas stream within the hydrate inhibitor injection unit such that the hydrate inhibitor lowers a hydrate formation temperature of the gas stream;
• and
• reducing a pressure of the gas stream within a pressure reduction unit.
