Abstract

See full text

Methods and systems for removing moisture from a refrigerant can utilize a desiccant-based system. The methods and systems can be employed in conjunction with a liquid natural gas (LNG) refrigeration circuit in either an online mode or an offline mode. For example, a system for removing moisture from a refrigerant can include: a refrigerant source; a moisture removal unit containing desiccant; and a refrigeration circuit comprising a refrigerant compressor, a refrigerant condenser, and a heat exchanger that are fluidly connected in a loop, wherein the refrigerant source is fluidly coupled to the moisture removal unit to supply a refrigerant from the refrigerant source to the moisture removal unit, and the moisture removal unit is fluidly coupled to the refrigeration circuit to supply the refrigerant from the moisture removal unit to the refrigeration circuit.
