Abstract: FIELD: polymer production. SUBSTANCE: invention relates to styrene (co)polymer production, including that in presence of elastomer, by continuous bulk polymerization. Method of continuously polymerizing styrene or styrene-acrylonitrile or methacrylonitrile mixture, or elastomer dissolved in styrene or styrene-acrylonitrile mixture consists in the following. Starting solution is fed into a series of reactors. A part of polymerization mass is withdrawn from a completely filled reactor into, connected with it, cooling zone, from which cooled polymerization mass is returned into corresponding reactors. Reliable, with regard to time, removal of polymerization heat from completely filled reactor wherein styrene (co)polymer concentration is maintained at the level 20 to 45 wt % and increase in the heat-removal efficiency in emergency cases are achieved thanks to (i) performing the cooling of a part of polymerization mass in completely filled heat exchanger to a temperature by 20-50 C below the temperature maintained in corresponding reactor and (ii) dividing cooled mass into at least two streams, one of which is returned into completely filled heat exchanger and the other(s) into reactor, weight ratio of the latter to the initial feed solution stream ranging from 0.7: 1 to 5:1, whereas weight ratio of the stream returned into completely filled heat exchanger to the initial feed solution stream is (5- 10):1.

Granted: 1998-09-20
Abstract: FIELD: oil production industry. SUBSTANCE: according to method, separation of water from recovered oil is performed by introducing demulsifier containing dysolvan into oil being recovered. Then, oil is heated and settled in separation vessel. Dehydrated oil is delivered into pipeline for transportation to heading transfer station. Introduction of demulsifier is performed periodically at well head in amount of 6-10 g per ton of oil being recovered. Heating is performed up to temperature of not less than +45 C with subsequent settling of oil in separation vessel during period of 1.5-2 h. Demulsifier with dysolvan additionally contains proxanol at ratio of components being from 1:3 to 3:1. Delivery of dehydrated oil into pipeline for further transportation is alternated with delivery into pipeline of separated water by way of their layer-by-layer withdrawal from separation vessel. Application of aforesaid method upgrades efficiency of treating recovered oil and of its further transportation due to deeper dehydration and reduced cost of dehydration.
