30TPD Waste Mineral Oil to Diesel Distillation Plant Installed in Kazakhstan Project Description

In late 2025, Henan Doing Company completed the installation and commissioning of a 30TPD waste oil distillation plant at a client's site in Kazakhstan.

This plant is designed to convert dark, impurity-heavy waste mineral oil into clear, high-value diesel and asphalt. The waste oil to diesel recycling process encompasses distillation, catalysis, multi-stage condensation, liquefaction, decolorization, and deodorization. Below are on-site photographs from the Kazakhstan waste mineral oil recycling distillation plant project:

The installed waste oil distillation machine employs a solid catalyst process, ensuring precise temperature control, efficient distillation and condensation, and effective decolorization. The waste mineral oil to diesel recycling system is highly automated, utilizes an environmentally friendly process, and delivers consistent performance, with a diesel yield of 70-80%.

Key Technical Features of DOING Waste Oil Distillation Machine:

1. Dual Heating System

Beyond direct fuel heating at the waste oil distillation reactor's base, our design integrates a thermal oil coil circulation system. This dual approach provides superior heat transfer within the waste oil, enabling continuous, efficient operation capable of processing multiple batches over extended periods.

2. Vertical Reactor Design

The distillation reactor features a vertical structure. This design allows for automatic gravitational discharge of residues post-distillation, simplifying operation and cleanup. The vertical footprint also saves significant floor space, reducing facility costs and enhancing practicality.

3. Environmentally Friendly Technology

Our DOING brand waste oil to diesel recycling distillation equipment uses solid catalytic fractional distillation, making the operation safer and cleaner. Furthermore, the plant includes a gas recovery and purification system that captures and recycles waste gases, boosting environmental compliance and energy efficiency while reducing waste.

4. High Manufacturing Standards

The equipment is constructed from boiler-grade steel plates with curved dished heads for excellent high-temperature and high-pressure resistance. Automated welding techniques, coupled with X-ray inspection of all seams, guarantee equipment reliability, stable performance, and safe long-term operation.

In October 2025, Doing Company engineers provided on-site guidance for installation and commissioning in Kazakhstan. The installation was executed with precision. To ensure stable long-term operation of this 30TPD waste mineral oil recycling to diesel distillation plant, our engineers also conducted comprehensive training for the local team on procedures, maintenance, and safety protocols.
