Abstract
Description
technical field
[0001] The invention relates to a sewage treatment method. Background technique
[0002] China's consumption of natural gas is increasing year by year. The shortage of domestic natural gas leads to an ever-increasing gap between supply and demand. The import of natural gas continues to increase, and the dependence on foreign countries reaches 30% to 35%. It is very necessary and urgent to develop the domestic natural gas industry. The Lurgi furnace is a mature pressurized coal gasification furnace technology. Due to its low gasification temperature (about 1000°C), low energy consumption, and less strict requirements on coal quality, it can synthesize a large amount of methane gas, and at the same time It can also obtain many commercial by-products, and it is currently the coal-to-gas technology with the largest number of plants in the world. Coal-to-natural gas consumes a lot of water, every 1000m produced 3 The water consumption of natural gas reaches 6-7 ...
