METHOD FOR PRODUCTION OF HOT WATER FROM HIGHLY SALINE WATERS Russian patent published in 1994 - IPC

FIELD: oil producing industry. SUBSTANCE: water flower, supplied to preliminary and final heating in recovery heaters, is produced by mixing in a certain proportion a portion of deaerated water and a portion of demineralized water produced in a thermal water demineralization plant (TWDP). The TWDP concentrate is supplied for heating the source highly saline water. Steam produced in a steam generator is used as heating steam in the water recovery heaters, in the TWDP, and in steam generator deaerator. The source highly saline water, which is fed in the TWDP, is softened by a sodium-cation process. Demineralized water, produced in the TWDP and used for feeding the steam generator, is directed to the additional deaeration. EFFECT: increased efficiency of the process. 3 cl, 1 dwg
