Hydrogenation system and hydrogenation method

Abstract

The invention relates to the technical field of hydrogenation, and discloses a hydrogenation system and a hydrogenation method. The hydrogenation system comprises a tube bundle vehicle set serving as a gas source and a hydrogenation machine used for hydrogenation of equipment to be subjected to hydrogenation, and the tube bundle vehicle set comprises at least one tube bundle vehicle and at least two groups of hydrogen supply tube bundles arranged on the at least one tube bundle vehicle; and hydrogen is stored in the hydrogen supply tube bundles, the initial pressure of the hydrogen is greater than the highest hydrogen storage pressure of the equipment to be subjected to hydrogenation, gas outlets of at least two groups of hydrogen supply tube bundles are respectively communicated with a gas inlet of the hydrogenation machine, and the hydrogenation system further comprises valves which are respectively used for controlling connection and disconnection between each group of hydrogen supply tube bundles and the hydrogenation machine. According to the hydrogenation system, gradient utilization of the hydrogen can be achieved, and the hydrogen utilization rate and daily filling capacity are effectively improved; and in addition, the hydrogenation system can not be provided with a storage tank or a compressor, so that the investment and energy consumption of fixed equipment can be remarkably reduced, and the hydrogen supply cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogenation, in particular to a hydrogenation system and a hydrogenation method. Background technique [0002] At present, domestic hydrogen refueling stations mainly use compressed hydrogen transported by tube-bundle vehicles as the gas source, and store the hydrogen in high-pressure storage tanks in the station through compressors. When there is a demand for refueling, hydrogen refueling equipment (such as fuel cell vehicles ) for decompression hydrogenation. [0003] However, for the above-mentioned hydrogen refueling station, since the initial pressure of hydrogen in the tube bundle car (about 20MPa) is lower than the pressure of the storage tank (above 35MPa), a compressor must be used to continuously take hydrogen from the tube bundle car to replenish the storage tank during operation. As a result, the daily filling capacity of the hydrogen refueling station is severely restricted by the displace...
