Commissioning of the oil sludge drying unit at Shanghai Petrochemical
Thread Content
Last month, Shanghai Petrochemical’s 952-ton/year oil sludge drying unit was successfully commissioned and produced qualified dried material. The project has significantly reduced the amount of oil sludge generated during the production and operation process at Shanghai Petrochemical that needs to be sent for disposal elsewhere. This project was established to handle the sludge and oil sludge from the oil-containing wastewater treatment units of the Environmental Protection Water Department, as well as the sediment from oil-containing wastewater tanks and sewage ponds. By subjecting oil sludge to dewatering and drying treatment, it is possible to reduce the amount of oil sludge, recover the contaminated oil, lower disposal costs, and decrease pollution emissions.
Could you introduce the general processing methods, processes, and suppliers?
The design institute is Shanghai Engineering Company, which also handles the EPC general contracting. You can get in touch with them and communicate.
This case is not a water sticker. This case provides a guiding direction, offering methods for enterprises that generate sludge oil, oily wastewater tanks, and sediment in wastewater ponds, to reduce the amount of oil sludge, recover used oil, lower disposal costs, and decrease pollution emissions.
Is the resulting dry material still considered solid waste or hazardous waste?
I would like to introduce the general process, design principles, product specifications, and other related aspects
Anything coming out of a chemical plant is considered hazardous waste until it has been tested. And it’s quite troublesome to determine whether a salt or some other substance is considered hazardous waste: L
It depends on the properties of the sludge; generally, the oily sludge from refineries contains a certain amount of heat energy, and after drying it can be used as fuel in boilers.
