10 Questions
What is the purpose of reintroducing the cooled vapor into the feed stream in the LNG liquefaction process?
To help pre-cool the gas to a temperature between -7oC and 4oC
What are some of the hydrocarbons that make up the mixed refrigerant used in the LNG liquefaction process?
Methane, ethane, propane, butane, and pentane
What is the pressure range for the low-pressure cycle in the LNG liquefaction process?
100 to 150 psia
What is the capacity, in million tonnes per annum (MTPA), that the LNG liquefaction process is capable of handling?
Up to 9 MTPA
What is the purpose of having two compressors in the LNG liquefaction setup?
To efficiently handle the load and avoid downtime in case of failures
What is the pressure range for the high-pressure cycle in the LNG liquefaction process?
300 to 350 psia
What happens if one compressor fails in the LNG liquefaction setup?
The remaining compressor can run the cycle to avoid downtime
How can the LNG liquefaction process reduce downtime if equipment fails?
By converting into a single refrigeration stream if necessary
What is the purpose of using raw natural gas in the pre-cooling stage of the LNG liquefaction process?
To help pre-cool the gas before further processing
Why are higher rated compressors needed in the high-pressure cycle of the LNG liquefaction process?
To handle the higher pressures efficiently
Learn about the BP Self Refrigerated Process patented by BP Corporation in 2002 for natural gas liquefaction. The process involves flashing NG stream at cold temperatures, utilizing the cold vapor stream to cool the natural gas stream, eliminating the need for external refrigerant.
