Produce more LNG with high precision controlling elements that enable optimal controller tuning
Main Cryogenic Heat Exchanger Solutions
The main cryogenic heat exchanger (MCHE) is the heart of the liquefaction facility. It liquefies natural gas then subcools it. The MCHE is composed of a large number of spiral wound tube bundles. When the feed gas exits the top of the MCHE, it has been turned into liquid as the temperature has been reduced to approximately -146°C (-231°F).
What's your opportunity?
- Maintain optimum refrigerant flow circulation
- Reduce energy consumption when feed is restricted
