Waste oil distillation equipment suppliers in China vary widely in process scope, documentation, manufacturing depth, and after-sales support. This non-ranked research list was reviewed on July 26, 2026 using publicly accessible company and product pages. Inclusion is not an endorsement, and website claims have not been independently verified.
Before selecting any supplier, send representative feedstock samples for testing and request a written mass balance, product test report, process flow, utility schedule, emissions and residue plan, safety documentation, layout, warranty, spare-parts list, and commissioning scope. Confirm whether the recovered fraction may legally be sold or used as diesel in the destination market; distillation alone does not guarantee compliance with EN 590, ASTM D975, or local road-fuel rules.
1. VBOLT
VBOLT is a Chongqing-based manufacturer of waste oil distillation equipment, used-oil re-refining systems, oil purification units, and solvent-extraction equipment. Its product scope covers both diesel-range fuel recovery and base-oil regeneration routes.
Buyers should ask VBOLT to match the process to the actual feedstock, target product specification, local permitted use, and required polishing steps. Review the proposed equipment list, heat source, vacuum system, gas treatment, residue handling, controls, and site services as one integrated package.
2. Henan Doing
Henan Doing publishes waste-oil distillation systems for used lubricating oil, pyrolysis oil, and related feedstocks. Its official product page also shows a wider portfolio of pyrolysis and recycling equipment.
When comparing a Doing proposal, verify the tested feedstock basis, realistic recoverable fractions, product quality after each treatment stage, fuel and power demand, non-condensable-gas handling, and the limits of any stated capacity or yield.
3. Jinxinsheng Environmental
Jinxinsheng Environmental presents a waste oil distillation plant for waste engine oil and tyre- or plastic-pyrolysis oil. Its broader website focuses on environmental projects, water treatment, and solid-waste management.
Because its current corporate portfolio is broader than oil processing, buyers should confirm which engineering, fabrication, commissioning, and long-term support functions are performed in-house for the exact distillation line being quoted.
4. Shangqiu Aotewei Environmental
Shangqiu Aotewei Environmental lists distillation and pyrolysis equipment on its official website. The company is relevant to buyers researching machinery for waste oil, pyrolysis oil, and other hydrocarbon feedstocks.
Ask for a feedstock-specific process description rather than relying on a generic machine configuration. Check pretreatment, fraction control, condensation, odor and gas management, product polishing, laboratory testing, and the disposal route for water, sludge, and heavy residue.
5. Henan Lanning Technology
Henan Lanning Technology publishes waste-oil distillation and broader waste-processing machinery. Its official product information describes systems for waste engine oil, black oil, used oil, and related materials.
Clarify whether the proposed line targets a diesel-range industrial fuel, a locally compliant road fuel, or a base-oil product, because these objectives require different process stages and verification. Request recent reference projects with comparable feedstock and capacity.
6. Chongqing Nakin Electromechanical
Chongqing Nakin Electromechanical manufactures oil purification equipment and lists a waste-oil distillation machine in its official product portfolio. Its location and wider filtration range may suit buyers comparing distillation with dehydration, filtration, and oil-treatment options.
Confirm the boundary between purification and distillation in the quotation. Water removal, fine filtration, fraction separation, desulfurization, color improvement, and final specification testing are separate functions and should be itemized clearly.
7. Shangqiu Hengze Environmental Equipment
Shangqiu Hengze Environmental Equipment lists waste-oil and mineral-oil distillation machinery alongside tyre and plastic pyrolysis systems. It replaces a marketplace-only entry in the earlier version of this list because its current official website provides a clearer source for initial research.
Buyers should separate claims made for pyrolysis plants from those applicable to liquid-oil distillation. Verify the reactor and vacuum design, materials of construction, automatic shutdown logic, condenser duty, gas treatment, residue discharge, and operator training.
8. Henan Jinzhen Machinery Manufacturing
Henan Jinzhen Machinery Manufacturing presents batch and continuous waste-oil distillation plants on its official website, together with tyre and plastic pyrolysis equipment. It is another supplier that buyers can include in a first-stage technical comparison.
Do not compare batch and continuous proposals on headline capacity alone. Check annual operating hours, feed preparation, startup and shutdown time, cleaning frequency, labor, energy use, maintenance access, turndown, and the evidence supporting continuous-operation claims.
9. Sihai Energy Technology
Sihai Energy Technology publishes vacuum distillation plants for waste crude oil, used engine oil, lubricating oil, and pyrolysis oil on its official website. The company also supplies pyrolysis equipment, so buyers should identify which process train applies to their liquid feedstock.
Request a clear battery-limit document showing which tanks, pumps, heaters, condensers, vacuum units, filters, control panels, gas-treatment devices, laboratory instruments, and site utilities are included or excluded from the offer.
10. Henan Realtop Machinery
Henan Realtop Machinery publishes waste-oil, pyrolysis-oil, and crude-oil distillation equipment. Its product range gives buyers another reference point for comparing process configurations and commercial scope.
Validate all performance statements through representative feedstock trials and third-party product testing. The purchase contract should define acceptance criteria, measurement methods, exclusions, warranty remedies, training, commissioning, and spare-parts support.
How to shortlist a waste oil distillation supplier
A credible shortlist should be based on comparable technical proposals, not website wording alone. Use the same feedstock analysis, target product specification, daily throughput, operating schedule, local utility conditions, emissions limits, and delivery boundary for every supplier. Then compare verified references, factory capability, process safety, expected mass balance, total installed cost, operating cost, product-testing plan, and contractual performance guarantees.
For a project-specific assessment, provide representative oil samples, laboratory data, the intended product use, local standards, site drawings, utilities, and required capacity. This information allows suppliers to propose a defensible process instead of a generic waste-oil-to-diesel machine.
