Biological natural gas is a green, low-carbon, clean and renewable natural gas produced by anaerobic fermentation, purification and purification with various urban and rural organic wastes such as crop straw, livestock and poultry manure, kitchen waste and agricultural and sideline product processing wastewater as raw materials. At the same time, the biogas residue and biogas liquid produced in the process of anaerobic fermentation can produce organic fertilizer.
The main components of biogas are CH4 and CO2. The high-purity methane gas obtained by separating CO2 from the mixture is called biological natural gas. Biogas can be directly used as an alternative fuel for Petrochemical Natural gas. The development of biogas has become an important direction to increase the supply of natural gas. The increase of human demand for natural gas promotes the development of biological natural gas technology. Biogas purification of biological natural gas can make high-value use of biogas, effectively reduce the greenhouse effect caused by the emptying of biogas project due to insufficient utilization of biogas, and has the dual benefits of environmental protection and energy..
Four new anaerobic fermentation units, straw storage shed, pump house, double membrane gas storage tank, natural gas compression plant, CNG filling station building, organic fertilizer processing, biogas residue and biogas liquid temporary storage tank, wastewater treatment tank and other projects are to be built, and 92 sets of straw chopper, grass grabber, loader, solid feeding system, pneumatic conveying tank, biogas liquid circulating tank and other instruments and equipment are to be purchased.
The large-scale bio natural gas pilot project makes full use of agricultural production residues such as straw and realizes the multi-level recycling of waste resources, which is of great significance for the development of ecological circular agriculture. The project not only helps to expand farmers' employment and increase farmers' income, but also protects the ecological environment and improves residents' living conditions. The economic, ecological and social benefits are very obvious.
The project requires real-time online monitoring of methane CH4, carbon dioxide CO2, hydrogen sulfide and H2S before and after natural gas purification, so as to adjust the corresponding process, improve the purity of natural gas purification and increase industrial benefits.
