Hazardous Waste Treated by Pyrolysis Introduction Video

As a trusted manufacturer of pyrolysis equipment, Henan DOING Company provides not only solid waste recycling pyrolysis solutions but also hazardous waste treatment solutions, achieving waste reduction and harmless treatment while promoting resource regeneration.

Oil sludge treatment by pyrolysis equipment

Watch this video to learn: What hazardous wastes can be treated by pyrolysis equipment?

We will focus on the three main categories of hazardous waste that our customers most frequently inquire about.

First up, waste oil sludge treatment. Tank cleaning sludge, packed with oil, is a standout. The pyrolysis process recovers a whopping 70% to 80% high-quality pyrolysis oil from this oil sludge—nearly up to crude oil standards. Then there's solid sludge, including drilling sludge, ground sludge, and steel plant sludge. After pretreatment to remove excess water, it’s pyrolyzed, and steel plant sludge also produces a recyclable steel slag as a by-product. Oil-based rock cuttings also fit here, offering high pyrolysis efficiency and quick oil production even at low temperatures.

Next, oil sludge-contaminated waste covers oil-stained items like paint buckets, packaging bags, and protective equipment. However, these items need to be sorted and collected to ensure that our hazardous waste pyrolysis equipment achieves optimal treatment results. We can also process petroleum oil refinery plant spent catalysts, but this depends on the oil content of the catalyst.

Oil sludge pyrolysis working flow

The third group is coal tar residue, similar to tank cleaning oil sludge but in liquid form. High-quality pyrolysis oil products can be produced through pyrolysis, making pyrolysis an ideal option for resource recovery from this type of oily sludge.
