PROCESS FOR TREATMENT AND TRANSPORTATION OF NATURAL GAS FROM GAS WELL

Japanese Patent JP3275114

B2

PURPOSE: To drastically reduce consumption of additives and cut the production cost of a gas, to thereby realize excellent application to development drilling of the natural gas and long distant transport of the same.
CONSTITUTION: In a zone G1 which is a well per se, a gas ascending to the ground surface is made into contact with at least part of a liquid phase obtained from recycling 4. The liquid phase contains water, and at least one anti-hydrate additive and/or at least one anti-corrosion additive. These additives are at least partly miscible and vaporize in a pure state or as an azeotrope. The resultant additive-containing gaseous phase is conveyed by conduits 3, 5 and cooled by a heat exchanger E1. Then, the gaseous phase is separated from an uncondensed gas in a tank B1, which uncondensed gas is recovered by a conduit 10, whereby a condensed liquid phase containing the additives is recycled to the contact zone G1 by conduits 9, 4.
