DOING Semi-Continuous Waste Oil Sludge Pyrolysis Unit Project In Malaysia

In October 2025, DOING, a pyrolysis unit manufacturer, completed the installation of two 10-ton semi-continuous waste oil sludge pyrolysis units for a Malaysian customer. This collaboration solved the Malaysian customer's waste oil sludge treatment problem, which can not only effectively extract fuel oil and combustible substances from waste oil sludge to generate benefits, but also reduce the environmental hazards caused by the disposal or landfill of waste oil sludge.

The collaboration between the two parties began in 2023. After the Malaysian client learned about DOING's past successful waste oil sludge pyrolysis cases, especially the advantages in the design of semi-continuous pyrolysis units, the client ultimately chose DOING.

In May 2023, a Malaysian customer visited our equipment factory, which became a key driving force for the collaboration. The customer witnessed firsthand how DOING constructed the pyrolysis unit using robust and durable materials to withstand the high temperatures and corrosiveness of the oil sludge, and expressed appreciation for the comprehensive equipment configuration of the pyrolysis unit. This positive feedback from the customer propelled the project forward, enabling us to finalize the specifications for two 10-ton semi-continuous waste oil sludge pyrolysis units.

The DOING semi-continuous pyrolysis unit achieves an optimal balance between batch and fully continuous operation when processing waste oil sludge with varying composition and moisture content. By allowing continuous feeding and periodic sludge removal, it avoids the high energy consumption and low thermal efficiency problems caused by frequent start-ups and shutdowns in batch operations, ensuring continuous temperature maintenance of the main reactor and significantly improving heating efficiency. Simultaneously, its batch feeding method provides flexibility to handle fluctuations in waste oil sludge characteristics, eliminating the risk of blockages or shutdowns caused by feed fluctuations that plague fully continuous pyrolysis units due to their stringent requirements for material homogeneity.

This balanced design philosophy enables the semi-continuous waste oil sludge pyrolysis unit to achieve high production capacity while maintaining stable feed. A sealing system ensures effective control of odor and emissions during operation. Compared to fully continuous systems, the semi-continuous pyrolysis unit is simpler to operate and more suitable for medium-sized waste oil sludge recycling projects seeking reliable operation, ultimately improving processing efficiency and stability while effectively reducing labor and energy costs.

The installation of the two 10-ton semi-continuous waste oil sludge pyrolysis units was also completed smoothly. In 2024, our engineers supervised the on-site assembly of the first pyrolysis unit, from foundation construction to system testing, ensuring everything was ready. The Malaysian customer then independently completed the installation of the second pyrolysis unit according to our guidance, and both waste oil sludge pyrolysis units were put into operation in October 2025.
