Natural gas ammonia. The natural gas is desulphurized first, and then through the second conversion, and then through a process of carbon monoxide shift and carbon dioxide removal respectively to obtain a mixture of nitrogen and hydrogen, wherein carbon monoxide and carbon dioxide are still contained in an amount of about 0.1% to about 0.3% by volume, and methanation After removal, pure hydrogen gas with a molar ratio of hydrogen to nitrogen of 3 was obtained, which was compressed by a compressor to enter an ammonia synthesis circuit to obtain product ammonia. A naphtha-based ammonia production process is similar to this one.
Our company havae ammonia storage tank for 2000m³.
Monthly we refilling cyliinders exporting about for 400tons.
and Tank shipping about 600tons.
We are the newest solid ammonia (SSCR)researcher and have coperated with FAW Jiefang.
According to Mr. Zhu Qixin, vice minister of FAW Jiefang Division, president of Commercial Vehicle Development Institute and deputy general manager of Jiefang, "Compared with the SCR technology widely used in the commercial vehicle market, SSCR technology has the advantages of high conversion efficiency, low failure rate and use cost Low salient features.At the same time, FAW liberation SSCR system uses inorganic salt adsorption of ammonia, compared with the traditional liquid urea, there is no problem can not evaporate, reduce the exhaust temperature, cover the catalyst, blocking the carrier and a series of problems.Different from the traditional need to use liquid Urea LSCR technology, SSCR technology does not need to add urea, to avoid the SCR technology, blocking, leakage, crystallization and other issues, greatly reducing the failure rate, while not requiring pumps and nozzles and other wearing parts, greatly reducing maintenance costs.
