Oilfield Refinery Factroy Oily Sludge Separation Oil Sludge Centrifuge


Oily sludge treatment Production of oily sludge


Oily sludge produced by petroleum in oil production, pipeline transportation, oil-gas combined stations, oil refineries, and oily wastewater.

Sludge treatment is a complete set of production process, using the principle of oxidative demulsification and centrifugal separation. Its main equipment is composed of dosing system, feeding system, separation system, conveying system, and control system.


After the oily sludge is collected and heated by steam, a suitable number of additives like demulsifier and active agent are added in it, so that the oily water in the emulsified state is broken. After demulsification, a high-efficiency LWS series three-phase centrifuge is adopted to realize the continuous separation of oil, water, and slag in the oily sludge, and the water separated and the oil-water mixture not demulsified are directly sent to the sewage treatment system for treatment. Then, a LW series two-phase centrifuge with high efficiency is used for dehydration. The crude oil residue in the dehydrated slag phase can be recovered by the combustion or thermal desorption process. The separated crude oil is collected and then purified by a three-phase flottweg separator. The purified oil can be reused.

Note: The throughput is related to material characteristics.

Separation performance:


1,About 80~90% oil can be recovered (relating to oil density, demulsification effect, temperature, etc.), and the recovered oil can be used for refining purpose after further purified by the flottweg separator;


2,The water content of the oil phase after separation can reach ≤3 ~ 5%;


3,The dryness of the slag phase after centrifugation can reach 40 ~ 60%, and its total volume is reduced by over 80% compared to that before separation;
