Title: Method of evaporating liquefied natural gas
Inventor: HANSU SHIYUMITSUTO
IPC: F17C9/04
Filed: 1988-12-19
Abstract: PURPOSE: To reduce the cost of equipment by making a partial flow of heated natural gas branch into a first circuit and, after being set at work, expanded, congulated, boosted, remixing it with the liquefied natural gas. CONSTITUTION: Liquefied natural gas in a conduit 1 is heated in three heat exchangers E1, E2 and E3, and then its partial flow is made to branch into a conduit 2a. Subsequently it is expanded at work in an expansion turbine X1, and it is congulated in the heat exchanger E1 by way of a conduit 2b and, after being boosted by a pump P1, this heated partial flow is remixed with the liquefied natural gas in the conduit 1. With this constitution, since a fluid is expanded by only one process, the numbers of the expansion turbine and the pump become lessened, and thus a reduction in the cost of equipment is well promotable.
