Oil and Gas industry uses several cryogenic equipment’s. These equipment need to remain isolated from external weather conditions like high temperature , rain, snow and wind to function it properly.
Cold box is a complete package of carbon steel casing with self -supporting structure that contain cryogenic equipment such as brazed plate fin exchangers, core in drums and associated piping and instrumentation. Insulation work for heat exchanger and piping assembly is done with perlite insulation.
It is modular package and should consume little time during installation. Piping and instrumentation in vendor scope save a lot of time.
For successful operation it comes with nitrogen purge system, relief hatch and dry out connection.
Cold box application in different filed of Oil and Gas sector:-
- Natural gas liquification.
