Feed Gas Chillers and Lef Condensers
A gas chiller can reduce the temperature of a gas stream to around 2oC. Temperatures below this can also be achieved but will result in freezing of the heat exchanger tubes. Where temperatures of less than zero are required it will be necessary to run tandem heat exchangers, switching the flow from one to the other as they become blocked with ice.
Chiller packages are, as with other items of purpose built process plant, unlimited in practical size.
It is often the case that suppliers of certain types of equipment, such as internal combustion engines and gas turbines, will specify a maximum moisture content in the gas to be fed to their plant. The options for dealing with such requirements are limited.
