Is the oil coke sludge and similar materials resulting from tank cleaning being fed back into the coking reprocessing process? Can it be refined?

What kind of process is this? Is a new device installation needed?

Could you introduce dry distillation and pyrolysis?

Resource utilization of waste sludge – Process overview of gas heat carrier cyclic depolymerization technology. Flow chart of the gas heat carrier cyclic depolymerization technology process. The oily sludge is first subjected to pretreatment; the treated sludge is then sent to a shaping system for solidification. The solidified material is transferred to a cyclic dry distillation depolymerization furnace where it undergoes dry distillation. The macromolecular polymers are heated and broken down, while the oil and gas generated as a result of this process, along with the circulating gas, are sent to an oil and gas recovery system. The oil is separated, the wastewater is reused, and the dry distillation gas is purified and heated before being reused. The device mainly includes: a pretreatment system, a shaping system, a circulating dry distillation and depolymerization system, an oil and gas recovery system, as well as an exhaust gas treatment and heating system. 1. Pretreatment System: This system uses crushing and sorting to pretreat oily sludge, so as to meet the feed requirements of the shaping system. 2. Setting system: The setting technology utilizes proprietary, environmentally friendly setting agents. This soluble curing agent achieves its maximum effectiveness at ambient temperature; it enables the sludge to set, forming solid spherical lumps that are suitable for use in processes involving the cyclic depolymerization, dry distillation, and pyrolysis of gaseous heat carriers. It solves common problems such as dust clogging and material coking that occur during dry distillation, thereby ensuring the continuous operation of the system. The composite curing agent contains components for sulfur fixation, nitrogen fixation, and metal fixation, which enable the removal of sulfur and nitrogen during the dry distillation process. It also binds to metal pollutants in the ash, preventing soluble metals from being released into the environment and thus meeting environmental protection requirements. 3. Circulating Dry Distillation Depolymerization System Circulating Dry Distillation Depolymerization Furnace Requirements for the material fed into the circulating dry distillation depolymerization furnace: oil content >5%, water content

Circular dry distillation depolymerization furnace: Requirements for the material fed into the circular dry distillation depolymerization furnace: oil content >5%, moisture content

We have processed it as hazardous waste

Oil coke cannot be used; it should be treated as hazardous waste.
