Abstract

The invention discloses a hydrogen production and hydrogenation integrated system in a natural gas station. The technical problems that an existing hydrogenation machine is limited in hydrogen supplycapacity and cannot meet different hydrogenation requirements are solved. The system comprises a hydrogen production integrated reactor, a gas-liquid separator, a PSA system and a hydrogen storage system comprising a multi-stage high-pressure gas storage tank which are connected in sequence, and a mixing unit, a conversion unit, a first cooling unit, a shift reaction unit and a second cooling unitare arranged in the hydrogen production integrated reactor in sequence; a first cooling water pipe and a second cooling water pipe are arranged in the first cooling unit and the second cooling unit respectively, an inlet of each cooling water pipe is connected with a water supply system, an outlet of each cooling water pipe is connected with a boiler system, and a steam generator leading to the hydrogen production integrated reactor is connected out of the boiler system. Hydrogen production in a natural gas station is achieved, the hydrogen production cost is reduced, cyclic utilization of heat exchange water is increased, resources and energy consumption are saved, and meanwhile the requirements of vehicle-mounted hydrogen storage bottles with different pressures are met.

Description

technical field [0001] The invention belongs to the technical field of hydrogen production and hydrogenation systems, and in particular relates to an integrated hydrogen production and hydrogenation system in a natural gas station. Background technique [0002] As a secondary energy source, hydrogen energy has been regarded as the most promising clean energy source in the 21st century. The alkane content in natural gas is extremely high, which is a good raw material for hydrogen production. At present, there are hydrogenation machines that provide hydrogen fuel for automobiles all over the world. The hydrogen in the station is mainly supplied by long-tube trailers and pipelines outside the station. After compression After the engine is pressurized, it is stored in the high-pressure storage tank in the station to refuel the vehicle. The natural gas station has a large amount of natural gas raw materials and mature and complete natural gas desulfurization equipment. The hydro...
