HORIZONTAL SETTLERS FOR SEPARATION OF THE OIL-WATER SLUDGE Russian patent published in 2007 - IPC B01D17/00 

FIELD: oil-producing industry; equipment for the field petroleum preconditioning.

SUBSTANCE: the invention is pertaining to the field petroleum preconditioning, in particular to the devices of the withdrawal of the intermediate layer from the settlers of the installations of the preliminary discharge of the water and the installations of the petroleum preconditioning. The horizontal settler for separation of the oil-water sludge contains: the body, the inlet and outlet fitting pipes, the sensors of the upper and lower levels of the intermediate layer, and also the intermediate layer withdrawal device, which is made in the form of the horizontal pipe with the horizontal perforated hollow shoes. The body is supplied with the drives with the coupling rods connected to the horizontal pipe by suspensions and made with the capability of the vertical relocation of the device for withdrawal of the intermediate layer within the limits of the intermediate layer at its withdrawal. The horizontal pipe is connected by means of flexible sleeves with the outlet fitting pipes for withdrawal of the intermediate layer supplied with the sampling valve. The techno-economical efficiency of the horizontal settler for separation of the petroleum-water sludge consists in reduction of the material inputs for the petroleum preconditioning due to the increased efficiency of the settler operation and improvement of the quality of the preconditioned petroleum, the increased reliability of the device operation for withdrawal of the intermediate layer, provision of the continuous operation of the settler, the increase of its productivity and the increase of the settler overhaul period.

EFFECT: the invention ensures reduction of the material inputs for the petroleum preconditioning, the increased efficiency of the settler operation, the improved quality of the preconditioned petroleum, the increased reliability of the device operation for withdrawal of the intermediate layer, provision of the continuous operation of the settler, the increase of its productivity, the increased overhaul period of the settler.
