Abstract
Method of cooling a hydrocarbon stream () such as natural gas, the method at least comprising the steps of (a) heat exchanging the hydrocarbon stream () against a first refrigerant stream () to provide a cooled hydrocarbon stream () and an at least partly evaporated refrigerant stream (); (b) compressing the at least partly evaporated refrigerant stream () using one or more compressors () to provide a compressed refrigerant stream (); (c) cooling the compressed refrigerant stream () after one or more of the compressors against ambient to provide a cooled compressed refrigerant stream (); (d) dynamically expanding the cooled compressed gaseous refrigerant stream () to provide an expanded refrigerant stream (); and (e) further cooling the expanded refrigerant stream () to provide an at least partially condensed refrigerant stream.
