A process and plant for natural gas liquids (NGL) recovery includes a main heat exchanger, a cold gas/liquid separator, a separation or distillation column, and an overhead gas heat exchanger. A pressurized residue gas generated from an overhead gas stream removed the top of the separation or distillation column is expanded and used as a cooling medium in the overhead gas heat exchanger and the main heat exchanger. The expanded residue gas, used as a cooling medium, is then compressed up to a pressure to be combined with the overhead stream from the separation or distillation column.

Methods for providing refrigeration in natural gas liquids recovery plants

The invention relates to a device (column) for bringing about a phase contact between a liquid phase and a gaseous phase, in particular a material exchange column, comprising: a shell, which extends along a longitudinal axis and bounds a shell space, at least a first circular tray, arranged in the shell space, for taking up the liquid phase, which extends crosswise to the longitudinal axis, whereby the at least one first tray has through openings for passage of a gaseous phase, so that the gaseous phase can come into phase contact with the liquid phase that is located on the at least one first tray. According to the invention, a large number of sealing weirs projecting from the first tray along the longitudinal axis are provided, which extend in each case along a radial direction of the at least one first tray, so that the first tray is divided into a corresponding plurality of sectors. In addition, the invention relates to an apparatus comprising such a device and a floatable carrier.
