Embodiment Construction

[0028] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] This system proposes a hydrogen-doped natural gas transportation and separation system. The natural gas pipeline transports hydrogen-doped natural gas and separates them to obtain pure hydrogen and natural gas with low hydrogen-doped ratio. The hydrogen-doped natural gas can also be directly used by natural gas users...

Abstract

The invention relates to a hydrogen-doped natural gas transportation and separation system and a control method thereof. The system comprises a hydrogen buffer tank, a natural gas pressure regulator, a natural gas hydrogen-doped gas mixing device, a monitoring module, a hydrogen-doped natural gas separation and purification device and a hydrogen storage device; and natural gas and hydrogen are respectively subjected to pressure treatment through the hydrogen buffer tank and the natural gas pressure regulator, then are conveyed to the natural gas hydrogen-doped gas mixing device through a natural gas transportation pipeline to obtain hydrogen-doped natural gas, and are transported to the hydrogen-doped natural gas separation and purification device through the natural gas pipeline to obtain pure hydrogen for hydrogen equipment to use or store. According to the system, hydrogen is transported and separated through the natural gas pipeline, the hydrogen transportation cost can be effectively reduced, and efficient utilization of energy is promoted.

Description

technical field [0001] The invention relates to the technical field of hydrogen-doped natural gas transportation and separation, in particular to a hydrogen-doped natural gas transportation and separation system and a control method thereof. Background technique [0002] As a clean energy that can be stored, generated, and burned, hydrogen energy has the characteristics of wide combustion boundary, wide distribution, high energy density, high conversion rate, and wide application. It is a major strategic direction of my country's energy transformation. At present, the global use of hydrogen energy is mainly concentrated in transportation, backup power and mobile devices, but the price of hydrogen is higher than that of traditional oil and gas fuels. The high cost has seriously affected the progress of commercialization of hydrogen energy. With the rapid development of hydrogen production technologies such as solar and wind energy hydrogen production, hydrogen production by e...
