Abstract:     An apparatus and method for producing liquefied natural gas. A liquefaction plant may be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream and a cooling stream. The cooling stream passes through a turbo expander creating work output. A compressor is driven by the work output and compresses the process stream. The compressed process stream is cooled, such as by the expanded cooling stream. The cooled, compressed process stream is divided into first and second portions with the first portion being expanded to liquefy the natural gas. A gas-liquid separator separates the vapor from the liquid natural gas. The second portion of the cooled, compressed process stream is also expanded and used to cool the compressed process stream. Additional features and techniques may be integrated with the liquefaction process including a water clean-up cycle and a carbon dioxide (CO2) clean-up cycle.

CROSS REFERENCE TO RELATED APPLICATIONS
    This application claims the benefit of U.S. Provisional Patent Application Serial No. 60/288,985, filed May 4, 2001 for SMALL SCALE NATURAL GAS LIQUEFACTION PLANT.

Family: Show 66 known family members

First Claim:
Show all 29 claims
What is claimed:     1. A liquefaction plant comprising:
  • a plant inlet configured to be sealingly and fluidly coupled with a source of unpurified natural gas;
  • a turbo expander positioned and configured to receive a first stream of natural gas drawn through the plant inlet and produce an expanded cooling stream therefrom;
  • a compressor mechanically coupled to the turbo expander and positioned and configured to receive a second stream of natural gas drawn through the plant inlet and produce a compressed process stream therefrom;
  • a first heat exchanger positioned and configured to receive the compressed process stream and the expanded cooling stream in a countercurrent flow arrangement to cool the compressed process stream;
  • a first plant outlet positioned and configured to be sealingly and fluidly coupled with the source of unpurified gas and to discharge the expanded cooling stream thereinto subsequent to passage thereof through the heat exchanger;
  • a first expansion valve positioned and configured to receive and expand a first portion of the cooled compressed process stream to form an additional cooling stream, the plant further including conduit structure to combine additional cooling stream with the expanded cooling stream prior to the expanded cooling stream entering the first heat exchanger;
  • a second expansion valve positioned and configured to receive and expand a second portion of the cooled compressed process stream to form a gas-solid-liquid mixture therefrom;
  • a first gas-liquid separator positioned and configured to receive the gas-solid-liquid mixture; and
  • a second plant outlet positioned and configured to be sealingly and fluidly coupled with a storage vessel, the first gas-liquid separator being positioned and configured to deliver a liquid contained therein to the second plant outlet.
