Abstract
A wet gas compression device combining the following stages: a separation stage providing a gas phase and a liquid phase; a conversion stage for converting a gas phase and a liquid phase; a conversion stage for converting the liquid phase provided by the separation stage to a vapor phase by heat exchange; a compression stage for compressing the gases from the separation stage and the conversion stage and for providing a portion of gas for use in the heat exchange of the compression stage.
Claims7
A wet gas compression device comprising in combination at least the following elements:
- a compression device suited to compress a gas, said compression device comprising at least one delivery line (2), at least one compressed gas discharge line (3), and one or more lines (5) designed for withdrawal or reinjection of at least a fraction of the gas circulating in the compressor,
- at least one wet gas delivery line (8),
- a circuit comprising at least the following elements:
- a separator (10) separating the liquid phase from the gas phase, said separator being connected to said gas delivery line (8),
- a liquid phase discharge line (11) and a gas phase discharge line (12),
- a heat exchanger (13),
- said heat exchanger (13) being connected at least to the following lines:
- a liquid phase delivery line (11),
- a compressed gas delivery line (5),
- a line (6) allowing to discharge the compressed gas, after heat exchange with the liquid fraction, to a compression stage,
- a line (14) allowing to discharge the liquid fraction vaporized by heat exchange.
