Disclosed is an apparatus and method for mixing transmission and separation of hydrogen gas and natural gas recovered based on pressure energy. The method includes: (1) hydrogen compressed natural gas is introduced into the pressure energy recovery system; (2) the low-pressure hydrogen compressed natural gas is introduced into the separation system; (3) the low-hydrogen natural gas and the, high concentration hydrogen gas are introduced into a first natural gas buffer tank and a first hydrogen gas buffer tank respectively; (4) the low-hydrogen natural gas and the high concentration hydrogen gas are introduced into the pressure boosting system; (5) the low-hydrogen natural gas and the high concentration hydrogen gas are respectively introduced into a natural gas user end. The method of the present invention is low in energy consumption, so as to realize pressure energy recovery, and energy consumption of hydrogen gas separation is greatly reduced.
SYSTEMS AND METHODS FOR PROCESSING GASES
The invention includes a gas processing system for transforming a hydrocarbon-containing inflow gas into outflow gas products, where the system includes a gas delivery subsystem, a plasma reaction chamber, and a microwave subsystem, with the gas delivery subsystem in fluid communication with the plasma reaction chamber, so that the gas delivery subsystem directs the hydrocarbon-containing inflow gas into the plasma reaction chamber, and the microwave subsystem directs microwave energy into the plasma reaction chamber to energize the hydrocarbon-containing inflow gas, thereby forming a plasma in the plasma reaction chamber, which plasma effects the transformation of a hydrocarbon in the hydrocarbon-containing inflow gas into the outflow gas products, which comprise acetylene and hydrogen. The invention also includes methods for the use of this gas processing system.
