摘要：The invention relates to methods for carrying out heat-mass-exchange

processes for a gas-liquid system, including air conditioning and drying, or purifying gasesof impurities of other gases, liquid vapor and dispersed solid particles from a gas, and canbe used in air conditioning systems, in the sanitary purification of gaseous emissions, andin treatment of natural or associated petroleum gases prior to the use or transportthereof (i.e. in drying or in the removal of higher hydrocarbons, hydrogen sulphide,carbon dioxide, etc.) The object of the present invention is to develop a simple, effectiveand reliable method for purifying gases of gaseous, liquid and solid impurities, to reducematerials consumption of equipment and to reduce operational costs. The essence of theinvention is that the condensate previously formed from gas flow to be purified andcooled to a temperature lower than the dew point of the gas flow is used as a cold heat-transfer fluid, which is in direct contact with the gas flow, in the purification of gases,including the cooling of a gas flow, the formation of a condensate and the separation ofsaid condensate, along with absorbed gaseous and mechanical impurities. A part of thepreviously obtained condensate, uncooled, is fed prior to the interaction of the gas to beseparated and the cooled condensate, in order to saturate the gas phase by vapor,resulting in an increased amount of condensate on the liquid or solid particles, thus

increasing separation efficiency. Gas purification is carried out in stages in order toseparate an individual component or group of components of the gas phase at eachstage. The advantages of the present invention are simplification of the gas purificationprocess, reduction of energy consumption and metal consumption of process

instrumentation, possibility of additional effective removal of solid impurities from gas,precise maintenance and automation of purification process parameters (i.e. the amountof vapors, dispersed gases and absorbed gases removed) by regulation of the

temperature and amount of fed condensate, and also possibility of avoiding significantlosses in gas flow pressure in the purification process by lowering the temperature of thegas by means of an external cooling source, rather than gas cooling by means ofthrottling thereof.
