Description
Изобретение касаетс осушки углеводородных газов, в особенности природного газа.The invention relates to the drying of hydrocarbon gases, in particular natural gas.
Известен способ осушки природных газов путем абсорбционной обработки их диэтиленгликолем (ДЭГ).There is a method of drying natural gases by absorption treatment with diethylene glycol (DEG).
Насьщенный влагой абсорбент регенерируетс .Moisture-rich absorbent is regenerated.
При температуре процесса абсорбции 20- 30°С этот способ может обеспечить температуру точки росы осушаемого газа -20°С. Дальнейша глубина осушки по этому способу не может быть достигнута, так как она обеспечиваетс либо повышением концентрации регенерированного ДЭГ, что значительно усложн ет процесс регенерации, либо понижением температуры абсорбции, что невозможно из-за резкого увеличени в зкости ДЭГ, ухудшени условий контактировани .At an absorption process temperature of 20-30 ° C, this method can provide a dew point temperature of the gas to be dried at -20 ° C. Further depth of drying by this method cannot be achieved, as it is provided either by increasing the concentration of regenerated DEG, which significantly complicates the regeneration process, or by lowering the absorption temperature, which is impossible due to a sharp increase in the viscosity of DEG and deterioration of the contact conditions.
С целью повышени степени осушки газа предлагаетс в качестве абсорбента использовать смесь диэтиленгликол с пропиленкарбонатом . Оптимальным вл етс использование смеси, содержашей 95-40 вес. % диэтиленгликол и 5-60 вес. % пропиленкарбопата.In order to increase the degree of gas drying, it is proposed to use a mixture of diethylene glycol and propylene carbonate as an absorbent. It is optimal to use a mixture containing 95-40 wt. % diethylene glycol and 5-60 weight. % propylenecarbate.
Применение предложенного способа позвол ет обеспечить осушку газа до точки его росы ниже -25°С.The application of the proposed method allows the gas to be dried to its dew point below -25 ° C.
процесса осушки газа и необходимой точки росы осушенного газа примен етс смесь (абсорбент ), с различным соотношением указанных ингредиентов (в вес. %),-например:the process of drying the gas and the desired dew point of the dried gas is applied mixture (absorbent), with different ratios of the above ingredients (in wt.%) - for example:
50% диэтиленгликол и 50% пропиленкарбоната - дл проведени процесса осушки влажного газа при температурах контакта газа и абсорбента -15°С и ниже. Температура замерзани -46°С.

В зкость при 38,77 ест.90% diethylene glycol and 10% propylene carbonate - for carrying out the process of drying wet gas at temperatures of contact of gas and absorbent + 10 ° C and below. The freezing temperature is -26 ° C. Viscosity at 38.77 eats.
