Petroleum and Petrochemical Water Treatment-Yangzhou Chenglu Environmental Engineering CO., Ltd

Petroleum and Petrochemical Water Treatment

Since its establishment, Chenglu has focused on water treatment and environmental services in the field of petrochemical industry, actively researched and developed various oily wastewater treatment processes and equipment, innovated and improved traditional biochemical processes, and established a perfect service system for users in different fields such as onshore oil exploitation, offshore oil exploitation, petrochemical industry, wastewater reuse, raw water treatment, zero discharge, etc, Provide comprehensive solutions.

The company's oil-water separation, filtration and biochemical products are widely used in many domestic and foreign key construction projects of Sinopec, PetroChina CNPC and CNOOC, and also enjoy a high reputation in the international market.

Solution

In the process of oil exploitation, oil refining and other industrial production, there will be a lot of crude oil, product oil and other oil substances in the drainage. The amount of wastewater is large, the water quantity fluctuates greatly, the composition of wastewater is complex and difficult to degrade, the nitrogen, phosphorus and other nutrients in wastewater are not balanced, the water quality varies greatly with the nature of crude oil processing and the process and method, and often contains heavy metals.

For such wastewater, we can design a reasonable and stable treatment process based on the process shown in the following figure according to the characteristics of different types of incoming water and waste oil.

Oil water separation
