Features
Multi-feedstock front-end pretreatment unit:
The mini refinery plant is equipped with sedimentation-dewatering and filtration-purification modules to remove mechanical impurities and free moisture in waste oil in advance. It avoids coking and blockage inside the high-vacuum distillation tower, protects tower packing components and extends the continuous-operation cycle of the whole plant.
Multi-stage vacuum distillation & refining system:
The mini refinery plant adopts gradient vacuum distillation to cut oil fractions of different boiling ranges under low-temperature and high-vacuum conditions. It reduces thermal cracking loss of oil materials, retains the original calorific-value index of fuel oil, and realizes separate output of diesel and heavy fuel-oil fractions.
Closed oil-gas condensation & recovery unit:
Oil vapor generated by distillation in the mini refinery plant is gradually cooled and liquefied through multi-stage gradient condensation towers. Light-oil and heavy-oil fractions are collected separately. Tail gas is recovered via closed pipelines to reduce fugitive oil-gas volatilization and material loss.
Streamlined PLC interlock control system:
Multiple safety interlocks for temperature, pressure and liquid level are configured. Automatic alarm and shutdown protection will be triggered under over-temperature and over-pressure conditions. Multiple sets of process formulas for different oil feedstocks are pre-stored. Parameters can be called with one-click when switching raw materials, and operators can get qualified after simple training.
Advantage
Multi-feedstock compatibility:
The mini refinery plant can process various raw materials including waste engine oil, tire pyrolysis oil, plastic pyrolysis oil and crude oil. Diverse raw-material sources reduce reliance on single-feedstock supply and improve the project's risk-resistant capacity.
Skid-mounted & compact with small footprint:
The complete mini refinery plant adopts integrated layout. No large-size workshop is required, and it can be deployed on ordinary hardened ground. Low civil-engineering investment makes it especially fit for small-scale recycling sites with limited space.
Low energy consumption via cascaded waste-heat recovery:
Incoming oil is pre-heated through multi-stage heat exchange with high-temperature side-stream fractions. Full waste-heat recovery cuts fuel consumption for heating and reduces processing cost per ton of oil.
Modular for relocation & capacity expansion:
The mini refinery plant is divided by functional modules for overall relocation following raw-material sources. Distillation or refining modules can be added for later-stage expansion without replacing the whole main unit.
Environment-friendly closed-loop production: Oil-gas condensation recovery and closed tail-gas treatment minimize leakage, dripping and waste-gas emission. Matched with desulfurization and dust-removal assemblies, it meets environmental-protection standards and applies to parks with strict environmental supervision.
Application Scenarios
- Centralized waste-engine-oil regeneration project: Collect waste engine oil and gear oil from society for centralized refining into diesel and fuel oil to realize resource-based utilization of waste oil.
- Post-refining project for tire & plastic pyrolysis oil: Crude pyrolysis oil from pyrolysis units is refined by vacuum distillation of this plant into market-ready fuel-oil products, extending the waste-material processing industrial chain.
- Overseas small-scale oil-processing project: Modular complete-unit export for small waste-oil recycling clients in Southeast Asia and Africa. Fuels are produced on-site to cut logistics cost of raw-material outbound transportation.
- Closed-loop waste-oil treatment project for industrial & mining enterprises: Large factories and mines generate large volumes of waste hydraulic oil and gear oil. On-site installation of the plant enables waste-oil recycling and lowers procurement cost of fresh oil.
Packing & Shipping
- Distillation towers, reaction tanks, heat-exchange & condensation tanks are treated for anti-corrosion and anti-rust. Dust-proof protective covers are installed for all flange nozzles. Tall tower sections are manufactured in split segments with reinforced bases for fixed bare-pack transportation to guarantee structural stability during ocean shipment.
- Precision electrical components such as PLC control cabinet, temperature-pressure transmitters and oil pumps are independently packed in shock-proof and moisture-proof solid-wood cases, marked with ocean-shipping labels: This Side Up, Moisture Proof, Fragile, to prevent damage from moisture during long-distance transportation.
- Tower trays & packings, sealing gaskets, adsorption filter media, special maintenance tools and spare wearing parts are packed by category. An independent material list is attached to each case for checking and acceptance at destination port.
- Main equipment modules are split to fit 40HQ container dimensions. Extra-long special-shaped components are shipped by bulk ro-ro vessel. Complete packing lists are provided and customers' on-site loading supervision is supported.
- Full-set technical documents are delivered together with goods: PID process flow diagrams, equipment assembly drawings, pressure-vessel inspection reports, operation & maintenance manuals, wearing-part lists and full-set customs-declaration documents.
FAQ
Q1: What raw materials can this mini refinery plant process?
A: It can process waste engine oil, tire pyrolysis oil, plastic pyrolysis oil, crude oil and mixed waste oil. Feedstock can be fed after simple sedimentation and impurity removal. Enhanced pretreatment shall be adopted if raw oil contains excessive colloids and impurities.
Q2: What is the capacity range of the equipment?
A: Standard models process 5 30 tons of oil feedstock per day. Non standard customization is supported and equipment specifications can be adjusted according to customers' actual processing scale.
Q3: Can the produced diesel be directly used as vehicle fuel?
A: Outputs from the unit are refined fuel oil, which can be directly used for industrial combustion, boilers and generator sets. Subsequent deep refining and desulfurization procedures are required to meet vehicle grade diesel standards.
Q4: How long is the continuous operation interval before decoking maintenance?
A: With qualified feedstock pretreatment, continuous operation for 20 40 days is achievable. High impurity raw materials will shorten operation cycle, and periodic slag discharge and decoking maintenance is required.
Production Process Flow
Raw-oil feeding → Pretreatment (sedimentation dewatering & filtration impurity removal) → Preheating via heat exchanger → Gradient heating by tube furnace → Fractionation cutting in vacuum distillation tower to extract light-diesel and heavy-fuel-oil fractions → Gradient condensation and liquefaction of each side-draw fraction → Bleaching-clay adsorption decolorization → Closed-filtration refining → Collection and metering in finished-oil tank; Non-condensable distillation
