Used oil refinery

Buyers must prioritize the processing capacity (TPD - Tons Per Day) and the distillation technology used (e.g., vacuum distillation, thin-film evaporation, or molecular distillation). It is crucial to verify the yield rate, which should typically be between 80% to 90% for high-quality base oil. Additionally, ensure the system includes an advanced filtration and decoloring unit to achieve the desired oil color and odor standards.

Due to the high-pressure and high-temperature nature of the process, equipment must adhere to ASME (American Society of Mechanical Engineers) or CE (Pressure Equipment Directive) standards. For electrical components, ATEX or IECEx explosion-proof certifications are mandatory to ensure operational safety in hazardous environments. Always request pressure vessel certificates and non-destructive testing (NDT) reports for the main reactors.

The heating method—whether thermal oil heating, electric heating, or direct fire—significantly affects the Total Cost of Ownership (TCO). Thermal oil heating is generally preferred for uniform heat distribution and preventing oil cracking. Buyers should evaluate the energy consumption ratio and ensure the system includes a heat recovery unit to reduce fuel costs by up to 20%.

To meet international environmental regulations, the refinery must be equipped with a three-stage exhaust gas treatment system (water scrubbers, activated carbon filters, and UV photolysis) to eliminate odors and harmful emissions. Furthermore, a closed-loop water cooling system is recommended to minimize water waste and prevent local environmental contamination.

Always conduct a Pre-Shipment Inspection (PSI) through reputable third-party agencies like SGS or Intertek. For complex equipment like oil refineries, it is highly recommended to perform a Factory Acceptance Test (FAT) where the machinery is operated using raw material samples before final payment. Utilizing Made-in-China.com's Secured Trading services can provide an extra layer of payment protection.

Focus negotiations on after-sales technical support and spare parts packages. Request a 2-year warranty on core components like the reactor and vacuum pumps. Instead of just pushing for the lowest price, negotiate for on-site installation guidance and operator training, which are critical for the successful commissioning of a refinery.

Refinery plants often involve oversized or overweight loads that require Flat Rack or Open Top containers. Ensure the supplier provides a detailed loading and lashing plan to prevent shifting during maritime transport. Confirm that the Incoterms (e.g., CIF or DAP) clearly define the point of risk transfer and that comprehensive marine insurance is purchased covering 110% of the invoice value.

Verify the HS Code (typically 841940) for distillation equipment to determine applicable import duties and anti-dumping taxes in your country. Ensure the supplier provides a Certificate of Origin (CO) to benefit from potential Free Trade Agreements (FTAs). Additionally, check if your local government requires an Environmental Impact Assessment (EIA) permit before the equipment arrives at the port.
