Slurry Preparation

Slurry Preparation and Bleacher

The incoming oil from N.O.T. pumped by BOPI, to oil earth mixer at operation temperature of 2nd water washing section, bleaching chemicals are proportioned into the oil earth mixer mechanically operated motorized rotary device. The slurry passes through the PH4 (pre-heater) achieving the bleaching temperature. The Bleacher operates under vacuum of 700mm Hg or absolute pressure 70mm of Hg.
The bleacher vessel is divided in to 3 compartments in order to prevent short circuiting of oil / bleaching earth slurry and equipped with the line steam injection in each compartments to maintain good mixing of bleaching chemicals and oil. After bleaching the slurry of hot oil and bleaching earth is transferred to the filter section for removing bleaching chemicals.

Filtration

The filtration takes place in two alternatively operating pressure leaf filters where the bleaching earth is completely removed from the oil while one filter is in operation the other filter is blown with steam in order to recover residual oil in the bleaching earth. This oil is separated from the steam in a cyclone.
After the filtration the oil is passed through one of two alternatively working security filters (PF11/PF12) before feeding to the deodorisation section.
