Technical Field

The invention belongs to the field of chemical reaction equipment and devices, and particularly relates to a gas chilling water washing filtering device.

Background

The domestic production capacity of natural gas in China is limited, and the rapid increase of the domestic demand cannot be met, so that the imported gas source in the natural gas consumption structure in China still accounts for a large proportion at present. In 2018, the national natural gas yield is 1077 billion cubic meters, the consumption is 1471 billion cubic meters, and the supply and demand gap is 394 billion cubic meters. In the 1-4 months in 2013, the natural gas yield in China is 402 billion cubic meters, the year-on-year increase is 7.7%, the import is about 171 billion cubic meters, the increase is 32.3%, and the large increase of the imported gas source indicates that the domestic gas source supply can not keep pace with the increase of the demand at present. The apparent consumption of the natural gas at the same period is 568 cubic meters, the specific increase is 13.2 percent, the total supply quantity of the natural gas is only 5 cubic meters higher than the consumption quantity, and the national self-supporting gap with the deduction of imported gas quantity is 166 cubic meters. The rapid increase of domestic resident consumption and the improvement of industrial gas for energy conservation and environmental protection can maintain the long-term growth trend of natural gas demand, and the pressure of the domestic supply guarantee capability of natural gas is more prominent.
