Methane extraction technology - biogas
PSA natural gas purification is a technology using adsorbent to separate gases such as methane, carbon dioxide and nitrogen in biogas to achieve the goal of methane enrichment. Biogas removes water through a liquid separation tank and then after desulphurization in a column enters PSA to produce natural gas product. Installation scale: 200~5000nm³/h.
Desulfurization technology using the redox wet method
HDS cyanogen desulfurization and removal technology is a wet oxidation method, which is a distinctive desulfurization method developed by Huaxi and scientific and technical personnel in the synthetic ammonia and coke industry, which allows the desulfurization percentage of H2S in gas to be at least 99.9%, and the desulfurization percentage of HCN to be more than 97%.
Flue gas desulfurization technology using ammonia
A by-product of desulfurization using the ammonia method is ammonium sulfate fertilizer; from 1 ton of ammonia you can get 4 tons of by-product ammonium sulfate, and its profitability depends on the prices of ammonium sulfate and ammonia.
Vinyl chloride recycling technology
After liquid separation in the vinyl chloride tail gas separator, a large amount of vinyl chloride and acetylene still remained, and the vinyl chloride and acetylene were concentrated for disposal by adsorption, which had high economic value. Installation scale: 100~10000nm³/h.
VOC tail gas disposal
Tank and loading waste gas, tail gas containing VOC in petrochemical and chemical industries. It is first condensed using the PSA method and then disposed of by condensation, which meets environmental drainage requirements and allows the recycling of some organic matter. Installation scale: 100-3000nm3/h
MEA-MDEA-NHD Desulfurization Technology
A typical amine desulfurization and decarbonization process consists of four parts: absorption, flash evaporation, heat exchange and regeneration (stripping).
