METHOD OF BORING REAGENT FABRICATION Russian patent published in 2009 - IPC C09K8/02 C09K8/10 C08H5/04 C08B15/06 C08L97/02

Abstract RU 2375404 C1

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production, can be used for boring reagent fabrication. At oxidation stage of lingosulphanate with sol of chrome hexad, at pH 1-1.5, production waste, generated at main product drying stage, additionally added into reaction zone. Production waste is lingosulphanate water solution, which includes residual amount of chrome elements at different oxidation stages.

EFFECT: injection of a waste flow into reaction zone allow to use lingosulphanate of different types and maintain the process at the stage of components active interaction, also increase boring reagent diluting factor and decrease sodium dichromate losses.
