PROCESS FOR TREATING OIL-FIELD WASTE WATERS AND PLANT FOR IMPLEMENTATION THEREOF

crude oil production. SUBSTANCE: process includes feeding initial waste water into settler as ascending flow, withdrawal of oil, gas, and purified water. According to invention, prior to be fed into settler, waste water is subjected to vacuum treatment in destabilizer following the conditions: Pin&g...

SUBSTANCE: process includes feeding initial waste water into settler as ascending flow, withdrawal of oil, gas, and purified water. According to invention, prior to be fed into settler, waste water is subjected to vacuum treatment in destabilizer following the conditions: Pin>= 1,05(ρ/2)(alpha+epsiin)V2W and Pout<= 0,95(ρ/2)(1-epsiout-d4m/Dout)V2m, where Pin is inlet pressure in destabilizer, Pout outlet pressure in destabilizer Pin inlet pressure in destabilizer; ρ density of water, alpha Coriolis coefficient, epsiin coefficient of hydraulic resistance in outlet section Vm water speed in destabilizer mouth; epsiout coefficient of hydraulic resistance inlet section; dm diameter of mouth, and Dout destabilizer outlet diameter, whereas pressure in settler does not exceed pressure saturation of water with gas before being fed into treatment zone. Waste water treatment plant comprises horizontal settler, destabilizer containing convergent tube conjugated with mouth and having length equal to at least two diameters, diffuser with variable obliquity between 5 and 5 deg. Destabilizer is also provided with driven adjusting needle with variable obliquity between 20 and 8 deg. Settler is provided with interior wall having inclined gutter in its upper part to let liquid overflow. Interior wall separates settler into preliminary and major chambers. The former includes transversal greed. EFFECT: enhanced efficiency of degassing due to vacuum treatment of initial water and use of destabilizer in plant. 2 cl, 1 dwg</description><language>eng</language><subject>CHEMISTRY ; METALLURGY ; TREATMENT OF WATER, WASTE WATER, SEWAGE, OR SLUDGE</subject><creationdate>2002</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20020220&DB=EPODOC&CC=RU&NR=2179533C2$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,777,882,25545,76296</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20020220&DB=EPODOC&CC=RU&NR=2179533C2$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>VINOGRADOV E.V</creatorcontrib><title>PROCESS FOR TREATING OIL-FIELD WASTE WATERS AND PLANT FOR IMPLEMENTATION THEREOF</title><description>crude oil production.
