A large amount of waste water is discharged in the process of oil refining, processing, storage and transportation, and its composition is complex and the discharge volume is large.

Oily wastewater mainly contains crude oil, refined oil, lubricating oil and a small amount of organic solvents and catalysts. The oily wastewater mainly comes from the condensed water in the device, oil and gas condensate, oil and gas washing water, oil pump shaft seal, oil tank cutting water and oil tank washing water, laboratory drainage, etc.

Sulfur-containing wastewater mainly comes from secondary processing equipment such as catalytic cracking, catalytic cracking, coking, aerobic cracking, and other secondary processing equipment in refineries. Drainage of the device.

The salty wastewater comes from crude oil electric desalination and dehydration tank drainage and the drainage of naphthenate production.

Phenol-containing wastewater mainly comes from atmospheric and vacuum, catalytic cracking, delayed coking, electro-refining, and stacking devices. Among them, the wastewater discharged from the top oil-water separator of the catalytic cracking unit has a high content of phenol.

Production wastewater mainly comes from circulating water plant cooling water blowdown, boiler water blowdown, oil tank spray cooling water, and pollution-free ground rainwater.

SP Solution:

Petroleum produces a large amount of water discharge, and its fluctuations are large. There are many types of chemical pollutants and large changes in content. Different links need to be equipped with some professional filters to purify products and promote the synthesis of downstream products. SP filtration technology is a technology that uses porous media or filter materials to separate undissolved solids from water. Through the wetting and collision coalescence of the filter materials, the oil and suspended solids in the sewage are removed.

SP Advantages:

ØHigh filtration accuracy and stable effluent quality.

ØRealize automatic backwashing, which can cope with unstable water quality fluctuations, without manual intervention, continuous operation, stable and reliable.

ØThe control system is responsive and accurate. It has the dual setting function of pressure difference and time, and flexibly adjusts the backwash pressure difference or time setting value.

ØWide application field, good filtering effect for wastewater with different composition properties, suitable for different raw water quality and water requirements.
