The output value of this project is considerable. The annual sales revenue of compressed natural gas is about 5 million calculated by 3 yuan/m3, which is enough for 100- 150 taxis. As the device involves flammable and explosive materials, high-pressure equipment and pressure vessels strictly supervised by the government, it is suggested to find a design unit to design natural gas purification process and gas compression filling device. Without formal design and construction, it is impossible to obtain government permission, safety production license and legal operation.
Where can there be such a large amount of biogas? Is this a farm? It is unlikely to produce so much biogas, so I'm afraid we should carefully measure the amount of biogas.
According to my experience in chemical industry, the investment of compressing into high pressure is less than 500,000 yuan, but if taxis and other motor vehicles are refueled, the investment of high-pressure natural gas storage tanks, refueling pricing equipment and refueling sites may exceed 6,543,800 yuan.
