Abstract
A method for producing liquefied natural gas includes receiving heated heat transfer fluid from a wellbore extending from a surface into an underground magma reservoir, receiving an initial natural gas stream, performing a purification operation on the initial natural gas stream to form a purified natural gas stream using the heated heat transfer fluid, and condensing the purified natural gas stream.
Claims20
A method for producing liquefied natural gas, the method comprising:
- receiving heated heat transfer fluid from a wellbore extending from a surface into an underground magma reservoir, the wellbore configured to heat the heat transfer fluid via heat transfer with the underground magma reservoir to form the heated heat transfer fluid;
- receiving an initial natural gas stream;
- performing a purification operation on the initial natural gas stream to form a purified natural gas stream using the heated heat transfer fluid;
- and
- condensing the purified natural gas stream.
