Description
Technical field
The invention belongs to reaction units, more particularly, to two-phase or multiphase a kind of reaction vessel.
Background technique
China's natural gas domestic production ability is limited, is unable to satisfy the rapid growth of domestic demand, therefore at present China
Import gas source also accounts for very big weight in natural gas consumption structure.2018, national 1077 billion cubic meter of gas production, consumption figure
1471 billion cubic meters, insufficiency of supply-demand is up to 394 billion cubic meters.1-4 month in 2013, China's natural gas yield are 402 billion cubic meters,
Increase by 7.7% on a year-on-year basis, import is roughly equal to 171 billion cubic meters, increases by 32.3%, increasing substantially for import gas source shows domestic gas at present
The paces for not catching up with demand growth still are supplied in source.568 billion cubic meter of same period natural gas Apparent con- sumption, increases by 13.2% on a year-on-year basis,
Natural gas overall supplies is only higher by 5 billion cubic meter of consumption figure, and deducting the domestic self-supporting notch of import tolerance is 166 billion cubic meters.State
