METHOD TO CONTROL THE PROCESS OF PRODUCTION OF POLYETHERS AND DEMULSIFYING AGENTS ON THEIR BASE Russian patent published in 2005 - IPC

FIELD: chemical industry; control over processes of production of polyethers and demulsifying agents on their basis.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to the methods of control over the chemical-technological processes of production of polyethers and demulsifying agents on their basis. The method of control over process of production of the alkaline polyethers and demulsifying agents is conducted in the mixers and in the reactor-etherificator at realization of reaction of the oxypropropylation and oxyethylation with utilization of the allocated zones of regulation and contours of circulation of the reaction mixture. Conduct corrective actions of control over the steam and a condensate consumption moisture and at that additionally install a can with a bubbler for a polyether and a detector of methanol consumption, a reactants stirring device, sensor units of consumptions, measuring tools and other equipment. For production of demulsifying agents from polyethers use cans with stirring devices with measurers and batchers components, screens for removal salts and the mechanical impurities, connected by corresponding pipelines with formation of contours of circulation of the reaction mixture equipped by means of measuring and control. The technical result is formation of the interrelated process control of production of polyethers and demulsifying agents. The invention allows to reduce power inputs and to expand the assortment of the produced products.

EFFECT: the invention allows to form the interrelated process control of production of polyethers and demulsifying agents, to reduce power inputs and to expand the assortment of the produced products.
