A mixed transport and separation device for hydrogen and natural gas

Abstract

The invention provides a mixed transport and separation device for hydrogen and natural gas. The mixed transport and separation device comprises a conveying pipe used for conveying materials; the conveying pipe is provided with a hydrogen energy input opening and a mixing device for mixing hydrogen energy and a material; the other end of the conveying pipe is provided with a separation and purification device capable of separating the hydrogen energy out; the separation and purification device is provided with a hydrogen energy output opening. The mixed transport and separation device for hydrogen and natural gas is characterized in that a conventional material conveying pipe is modified and the hydrogen energy input opening and the hydrogen energy output opening are added; hydrogen energy and a material are mixed and separated in input and output processes, and thus hydrogen energy is transported. The device can achieve large-amount, efficient and stable hydrogen energy transport via existing material conveying pipelines, thereby providing the most economical hydrogen energy transport mode and providing necessary support for hydrogen energy application in urban regions.

Description

technical field [0001] The invention relates to the technical field of energy transportation, in particular to a hydrogen and natural gas blending transportation and separation device. Background technique [0002] China's annual hydrogen production has exceeded 10 million tons, ranking first in the world. Industrial-scale hydrogen production methods mainly include two methods: fossil energy hydrogen production such as methane steam reforming and clean energy electricity electrolysis of water for hydrogen production, of which fossil energy such as coal chemical industry and methane reforming account for 96%, and electrolysis of water for hydrogen production The production of hydrogen accounts for about 3% of the world's total hydrogen production, and many industrial production processes such as chlor-alkali and methanol production process produce a large amount of hydrogen as a by-product accounting for about 1%. Although hydrogen production from fossil energy is currently ...

AI Technical Summary

Problems solved by technology

At present, whether it is liquid hydrogen low-temperature transportation or high-pressure tank transportation, this ultra-low temperature and high-pressure process will cause specific energy consumption

However, the large-scale fuel cell power generation technology and hydrogen gas turbine power generation technology on the application side are also affected by hydrogen transportation and the lack of cheap and stable hydrogen sources, and the current development is slow.
