Improvement of natural gas hydrogen production process in natural gas hydrogen production plant
The hydrogen purification process in the natural gas hydrogen production device is mainly to form an adsorption bed with silica gel, activated carbon, and alumina under appropriate conditions, and use the adsorption bed to adsorb the impurity components in the shift gas under appropriate pressure conditions. The hydrogen that is not easily adsorbed is output from the outlet of the adsorption tower, thereby achieving hydrogen purification. The following natural gas hydrogen production device-Suzhou Jiarui gas to introduce the improvement of natural gas hydrogen production process :
Through the transformation of the conversion furnace and heat recovery system, cost savings can be achieved and the consumption of natural gas raw materials can be reduced. This technology produces carbon dioxide, hydrogen and carbon monoxide by hydrodesulfurization of natural gas and pyrolysis and reforming of a proper amount of special catalysts placed in the conversion furnace. The conversion gas is then subjected to heat recovery, and the content of carbon monoxide in the conversion gas is reduced by carbon monoxide conversion, and then purified by PSA pressure swing adsorption to obtain pure hydrogen.
The hydrogen purification process in the natural gas hydrogen production device is mainly to form an adsorption bed with silica gel, activated carbon, and alumina under appropriate conditions, and use the adsorption bed to adsorb the impurity components in the shift gas under appropriate pressure conditions. The hydrogen that is not easily adsorbed is output from the outlet of the adsorption tower, thereby achieving hydrogen purification. The main performance indicators and technical indicators of this process are as follows :
1, the production capacity is generally 500 ~ 100000 m3 / h, the purity of hydrogen products can reach 99.99 %, the pressure of the product is about 1.5 MPa ;
the amount of raw materials is 20-5000 m3 / h, the purity of hydrogen is generally about 99.9 %, and the extraction rate of hydrogen is about 80 %.
The above is organized and released by the natural gas hydrogen production device-Suzhou Jiarui gas. Suzhou Jiarui Gas System Co., Ltd.is a science and technology company specializing in the research and development of gas separation and purification technology.
