METHOD OF FIELD PREPARATION OF A CONDENSATE-GASEOUS FLUID AND DE-ETHANIZATION OF THE CONDENSATE Russian patent published in 2005 - IPC

FIELD: natural gas industry.

SUBSTANCE: the invention is pertinent to the field of natural gas industry and may be used for the field preparation of products of gas condensate pools. The method provides for separation of a gas with a delivery and a low-temperature stage of separation, a phase separation of a condensate of a delivery and low-temperature stages of separation, degassing of a condensate and de-ethanization of a condensate in an evaporating rectifying column. The whole volume of a delivery stage of separation after a preliminary degassing and heating in a recuperative heat exchanger is fed into the middle part the evaporating rectifying column as a feeding. The condensate of the low-temperature stage of separation is divided into two streams. The first stream is fed into the upper part of the evaporating rectifying column as a sprinkling, the second stream is fed in the degasator. Adjustment of the technological mode and composition of products of de-ethanization depending on output and compositions of the condensate of the delivery and a low-temperature stages of separation is conducted by a change of volumes of the streams. The technical result is - maximum degree of separation of the de-ethanizated condensate at minimum losses with a dried gas.

EFFECT: the invention ensures maximum degree of separation of the de-ethanizated condensate at minimum losses with a dried gas.
