The most frequently asked questions for PPGT waste oil recovery systems.

Find informative answers to all your questions about our plants below.

There are 2-3 consumables which will be needed for PPGT-BP/LP waste oil distillation equipment are as following, one is our formulated catalyst, another one is refining adsorbent, and catalyst for desulfurization process of diesel fuel is required as well. As a matter of fact, those consumables required for PPGT process are carefully selected and proved to be essential to the distillation/pyrolysis process even for those famous refineries from all over the world. Please consult our sales for more information about the catalysts and what role it plays during the whole distillation process.

There will be no smell at all as the gas produced by PPGT-BP/LP waste oil distillation plant will be purified by our exclusive tail gas purification unit before emission.

The byproduct are usually comprised of gas, water, oil sludge/residue and catalysts. The gas will be purified before emission or to be recycled as heating fuel; The water will be filtrated and purified as cooling water; The oil sludge could be used for burning or to be raw material for producing asphalt or road constructions. The catalysts can be reactivated by microwave or other technologies for reuse. Or to be handed over to the professional recycler for disposal.
