TSC Announce New LNG Simulation.

Posted by Marketing on Thursday 19th January 2017

TSC Simulation have recently developed a full plant dynamic simulation of a Liquefied Natural Gas (LNG) liquefaction process.

With the growth in natural gas use around the world, the transportation of gas over long distances has become an ever increasing challenge. By cooling and liquefying the gas, transportation costs are greatly reduced. LNG has a volume of roughly 1/600 of the gaseous form and to liquefy the gas it must be cooled to approximately -155 °C.

To achieve the extreme temperatures required for the process, an integrated dual loop cooling system is used. A four stage propane cooling loop is initially used to cool the process gas before being used to provide the cooling for a 2 stage multi component refrigeration loop. After going through 6 stages of cooling the natural gas is finally expanded to reach the desired temperature which enables it to become fully liquefied.

The extreme temperatures used within this process prove a unique challenge for operation and problem solving, which can best be learned and practised through realistic dynamic simulation.

The TSC simulation includes gas reception, CO2 removal, gas dehydration, gas fractionation, propane cooling system, multi component refrigeration, storage and loading.

The model is supplied with a TSC Simulation type DCS emulation system including alarms, trending and emergency shutdown system. The model includes the full TSC fault injection system allowing fault finding and unusual operation exercises to be carried out.
