Biogas Purification Project of Bene-Sino Corperition - Case Study
Bio-natural gas is green, low-carbon, clean and renewable natural gas produced by anaerobic fermentation, purification and purification of various urban and rural organic wastes such as crop straw, livestock and poultry manure, food waste, agricultural and sideline product processing wastewater, etc. The biogas residue produced in the oxygen fermentation process can produce organic fertilizer. The main components of biogas are CH4 and CO2, and the high-purity methane gas obtained by separating CO2 from the mixed gas is called bio-natural gas. Bio-natural gas can be directly used as an alternative fuel for petrochemical natural gas, and the development of biogas has become an important direction to increase the supply of natural gas. The increase in human demand for natural gas has promoted the development of bio-natural gas technology. Biogas purification biogas can be used for high-value biogas, effectively reducing the greenhouse effect caused by the emptying of biogas projects due to insufficient biogas utilization, and has dual benefits of environmental protection and energy.
BENE-SINO project is a large-scale biological natural gas pilot project of the National Development and Reform Commission and a large-scale biological natural gas demonstration project of the Ministry of Agriculture and Rural Affairs; the total investment of the project is 90.75 million yuan, of which: the central government invests 31.55 million yuan and the enterprise raises 59.20 million yuan.
Newly built 4 anaerobic fermentation plants and projects such as straw storage yard, pump room, double membrane gas storage tank, natural gas compression plant, CNG filling station, organic fertilizer processing, biogas residue and biogas slurry temporary storage tank, wastewater treatment tank, etc. , To purchase 92 sets of equipment (sets) such as straw hoppers, grass grabs, loaders, solid-state feeding systems, pneumatic conveying tanks, and biogas liquid circulation tanks.
The large-scale bio-natural gas pilot project makes full use of agricultural production residues such as straws and realizes the multi-level recycling of waste resources, which is of great significance to the development of ecological recycling agriculture. The project is conducive to expanding farmers’ employment and increasing farmers’ income, and it can also protect the ecological environment and improve the living conditions of residents. The economic, ecological and social benefits are very obvious.
The BENE-SINO project requires real-time online monitoring of methane CH4, carbon dioxide CO2, hydrogen sulfide H2S gas content before and after natural gas purification, so as to adjust the corresponding process, improves the purity of natural gas purification, and increase industrial benefits.
The customer uses portable biogas analyzer GASCHEK-1000 and an explosion-proof design online laser gas online monitoring device BIOGA-1000, and simultaneously monitors the content of methane CH4, carbon dioxide CO2, oxygen O2, hydrogen sulfide H2S, and the technology is advanced and automated, effectively reducing project operating costs, reducing manual calibration operations, adopting automatic drainage and other measures to greatly reduce the workload of the site.
