A process for removal of mercury in a gas dehydration system comprising (a) adding a complexing agent to a recirculated glycol solvent as part of the glycol solution feed prior to or at the dehydration liquid contactor and recirculating continuously with the glycol solvent, (b) selectively reacting the complexing agent with mercury in the wet natural gas to remove the mercury from the dry natural gas product, (c) and feeding the rich glycol with the complexing agent to a regenerator and continuously regenerating.

Process, method and system for removal of mercury in a gas dehydration process

Disclosed is a process for liquefying natural gas wherein an available methane-rich feed, i.e., natural gas, at an excess pressure is initially expanded to provide expansion work which may be utilized in a number of novel ways, such as to provide refrigeration in a refrigerant cycle used to cool the feed or in one or more refrigerant cycles used in a liquefaction zone to liquefy the feed, or to generate electrical power for use in the liquefaction process or for export. In one embodiment, the expansion work is obtained by use of an expander/compressor device (turboexpander) which expands the feed to (1) drive the compressor of the device and thereby provide compression for a closed loop propane refrigeration cycle to pre-cool the natural gas stream, and (2) produce an expanded, chilled natural gas feed for a liquefaction process. The production of a chilled natural gas feed to a liquefaction process can either increase the volume of LNG production for a given amount of installed horsepower, or alternatively, can be used to reduce the capital cost and/or operating cost associated with the production of a given amount of LNG.
