CONFIGURATIONS AND METHODS FOR LNG REGASIFICATION AND BTU CONTROL

摘要

LNG is pumped to supercritical pressure and vaporized, preferably in an offshore location to thereby form a natural gas stream with an intermediate temperature. A first portion of that stream is then processed in an onshore location to remove at least some non-methane components to thereby form a lean LNG, which is then combined with a second portion of that stream to form a sales gas having desired chemical composition. The intermediate temperature and the split ratio of the gas stream in first and second portion are a function of the concentration of the non-methane components in the LNG.
