Gas treatment process and process arrangement

The present invention proposes a gas treatment process in which a process arrangement comprising three process units is used, the gas treatment process comprising subsequently operating a different one of the three process units in a heating mode during a heating phase, the heating mode comprising heating a first gas stream to a first temperature level using a first heat exchanger, introducing the first gas stream at the first temperature level to the process unit which is operated in the heating mode, withdrawing a second gas stream from the process unit which is operated in the heating mode, and thereafter cooling the second gas stream to a second temperature level using a second heat exchanger.

Claims preview

1 . A gas treatment process in which a process arrangement comprising three process units is used, the gas treatment process comprising subsequently operating a different one of the three process units in a heating mode during a heating phase, the heating mode comprising heating a first gas stream to a first temperature level using a first heat exchanger, introducing the first gas stream at the first temperature level to the process unit which is operated in the heating mode, withdrawing a second gas stream from the process unit which is operated in the heating mode, and thereafter cooling the second gas stream to a second temperature level using a second heat exchanger, wherein the first heat exchanger and the second heat exchanger are operated in fluidic integration into a heat transfer arrangement operated using a heat transfer fluid, the heat transfer arrangement further comprising a heat transfer fluid heater, a first buffer vessel, a heat transfer fluid cooler and a second buffer vessel, an outlet of the heat transfer fluid heater being operated in permanent fluidic connection with an inlet of the first buffer vessel, an outlet of the first buffer vessel being operated in permanent fluidic connection with an inlet of the first heat exchanger, an outlet of the heat transfer fluid cooler being operated in permanent fluidic connection with an inlet of the second buffer vessel, and an outlet of the second buffer vessel being operated in permanent fluidic connection with an inlet of the second heat exchanger, in a first connection mode an outlet of the first heat exchanger is operated in temporary fluidic connection with an inlet of the heat transfer fluid heater while an outlet of the second heat exchanger is operated in temporary fluidic connection with an inlet of the heat transfer fluid cooler, and in a second connection mode the outlet of the first heat exchanger is operated in temporary fluidic connection with the inlet of the heat transfer fluid cooler while an outlet of the second heat exchanger is operated in temporary fluidic connection with an inlet of the heat transfer fluid heater. 2 . The gas treatment process according to claim 1 , wherein the heat transfer fluid is transferred from the first buffer vessel to the inlet of the first heat exchanger using a first pump and wherein the heat transfer fluid is transferred from the outlet of the second buffer vessel to the inlet of the second heat exchanger using a second pump. 3 . The gas treatment process according to claim 1 , wherein one of the first connection mode and the second connection mode is selected on the basis of a heat amount transferred in the first heat exchanger and the second heat exchanger by a control unit.
