Abstract: The present invention relates to a system for treating and cooling a hydrocarbon stream, comprising—a gas treatment stage comprising a pre-cooler to cool at least part of the hydrocarbon feed against cooling water, —a first cooling stage comprising one or more first water coolers, —a second cooling stage comprising one or more second water coolers. The system comprises a cooling water unit arranged to receive a stream of cooling water and supply a first part of the stream of cooling water to a chilling unit to obtain a stream of chilled cooling water and pass the stream of chilled cooling water to a selection of the at least one pre-cooler, the one or more first water coolers and the one or more second water coolers.

Abstract: The invention relates to a method and system of preparing a lean methane-containing gas stream (22), comprising: —feeding a hydrocarbon feed stream (10) into a separator (100); —withdrawing from the separator (100) a liquid bottom stream (12); —passing the liquid bottom stream (12) to a stabilizer column (200); —withdrawing from the stabilizer column (200) a stabilized condensate stream (13) enriched in pentane, —withdrawing from the stabilizer column (200) a stabilizer overhead stream (14) enriched in ethane, propane and butane; —splitting the stabilizer overhead stream (14) according to a split ratio into a main stream portion (15) and a slip stream portion (16), —passing the slip stream portion (16) to a fractionation unit (300) to obtain an ethane enriched stream (17) and a bottom stream enriched in propane and butane (18).
