Waste ship oil sludge into renewable fuel conversation process

The conversion of waste ship oil sludge into renewable fuel is a complex process that typically involves several stages, including pre-processing, pyrolysis and post-processing. Here’s an overview of the steps involved:

Process of recycling waste ship oil sludge to renewable fuel oil

1. Preprocessing the waste ship oil sludge

Collection and Storage: Waste ship oil sludge is collected from ships and stored in specialized containers to prevent environmental contamination.

Dewatering and Filtration: The waste oil sludge undergoes dewatering and filtration to remove excess water and solid particles, which can interfere with the pyrolysis process.

2. Pyrolysis the waste ship oil sludge

Feeding into Reactor: The preprocessed waste ship oil sludge is fed into a pyrolysis reactor. For this application, DOING batch type and continuous type waste ship oil sludge conversation pyrolysis equipment are suitable.

Thermal Decomposition: Inside the pyrolysis reactor, the waste ship oil sludge is subjected to high temperatures (typically between 400°C and 500°C) in the absence of oxygen. This causes thermal decomposition, breaking down the waste ship oil sludge into oil and gas.

Oil Gas Cooling: The oil and gas enter the condensation system through the oil and gas pipeline, are fully cooled into oil and stored in a temporary storage tank.

3. Post-processing

Refining Oil: The fuel oil produced by pyrolysis may require further refining to improve its quality and stability, making it suitable for use as a renewable fuel.

Utilization of Syngas and Solid Residue: The non-condensable gas could be recycled back to the reactor for use as fuel. The non-combustible and uncooled gas is discharged after the tail gas purification device. The solid residue can be used for landfill and building construction.

The above is the process of converting waste ship sludge into renewable fuel. Due to the high viscosity and strong corrosiveness of waste sludge, during the high-temperature pyrolysis process, as the furnace temperature gradually increases, the waste sludge is easy to adhere to the inner wall of the pyrolysis reactor and form coke in the inner layer of the furnace. Once there is a coke layer on the inner wall of the furnace, it will cause a series of problems, such as shortened equipment service life, incomplete sludge pyrolysis and other process and safety issues.

To address this problem, DOING waste ship oil sludge conversation pyrolysis equipment has two unique designs:

1.Equipment material:

The furnace of DOING waste ship oil sludge conversation pyrolysis equipment supports customized 304/316/309S/310S stainless steel materials, which can effectively reduce the phenomenon of coking and wall adhesion caused by waste ship oil sludge pyrolysis. On the other hand, the use of stainless steel can resist high temperature and corrosion, extending the service life of the equipment.

2.Decoking device:

DOING engineers designed a decoking device in the reactor. When the reactor rotates, the device moves to remove existing coke and prevent new coke from forming through scraping and friction. Usually, DOING recommends the use of a decoking mace device for intermittent waste oil sludge pyrolysis treatment equipment, and recommends the use of a decoking energy storage ball for continuous waste oil sludge pyrolysis treatment equipment.

Converting waste ship oil sludge into renewable fuels through pyrolysis is an environmentally friendly and profitable process. Waste ship oil sludge pyrolysis not only has a high oil yield, up to 80-90%, but also has good oil quality. DOING has many oil sludge pyrolysis cases.
