METHOD OF OIL RESIDUE UTILISATION AND CHEMICAL AGENT THEREOF

摘要

The invention is related to the field of oil-producing and oil-refining industry and, in particular, to the utilization methods of oil residue formed at the oil gathering-and-treating terminals and accumulated at the oil removers, earthen containers, reservoirs and setting vessels. An inexpensive and efficient utilization of an oil residue is provided due to said oil residue subjected to dilution (at the minimum environmental temperature of 0°C), setting and separation into respectively aqueous, hydrocarbon and solid phases, pumping out said aqueous phase and recycling said hydrocarbon phase, while the dilution is performed by means of said aqueous-hydrocarbon emulsion system formed by mixing oil with a chemical agent in the following ratio: oil - from 1 to 10 parts in volume chemical agent - 1 part in volume, while said chemical agent presents a solution of liquid glass in D.C.- activated water having pH=9-12 with the following ratio of components: liquid glass - from 0,3 to 25% D.C.-activated water having pH=9-12 - the rest up to 100% which makes it possible to recycle up to 90% of an oil residue as recovered oil.
