VAPOR RECOVERY SYSTEM USING TURBOEXPANDER-DRIVEN COMPRESSOR |
摘要 |
A method for recovering gas is described and includes compressing gas with a turboexpander-driven compressor. The compressor may be a high speed cryogenic centrifugal compressor and the gas to be recovered may be generated from a source of liquefied gas, such as during the transfer of liquefied natural gas from a shipping vessel to a storage tank. A system for recovering gas is also provided and includes a turboexpander-driven compressor in communication with a source of gas to be compressed. The system may be provided with a circuit such that at least a portion of the compressed gas, and/or at least a portion of an expanded, reduced-pressure gas exiting the turboexpander, is directed to the source of the gas. |
