Features
1. Integrated Crude Oil Desalting & Dehydration Pretreatment System
This mini refinery integrates electric desalting and settling dehydration functions to effectively eliminate salt content, free water and sediment contaminants in crude oil. It prevents salt scaling accumulation inside fractionation towers, protects heating furnaces and internal tower components, and delivers long-term stable and trouble-free system operation.
2. Compact Combined Atmospheric & Vacuum Distillation Structure
Adopting a simplified dual-tower integrated layout, the unit combines atmospheric distillation and vacuum distillation processes. The atmospheric tower extracts light oil fractions, while the vacuum tower further processes residual heavy oil. It realizes multi-grade oil separation with a minimized footprint, abandoning the bulky and complex structural design of large-scale refineries.
3. Special Tube Furnace Heating & Waste Heat Recycling Module
Equipped with a customized small-sized heating furnace, the system provides staged gradient heating for crude oil. Optimized flow rate control inside furnace tubes effectively reduces coking risks of heavy crude materials. Matched flue gas waste heat recovery equipment reuses exhaust heat to preheat incoming crude feedstock, achieving efficient energy recycling.
4. Multi-point Side-draw Fractional Separation Design
The refinery is configured with multiple side discharge outlets to independently extract naphtha, diesel and heavy fuel oil. Each fractional pipeline is equipped with dedicated cooling devices and precision metering modules, enabling separate collection, accurate measurement and classified storage of all finished oil products.
Advantage
1. Low Capital & Operational Investment
Compared with traditional large-scale refineries, this mini unit features lower equipment costs and fewer auxiliary facility requirements. It perfectly matches the production characteristics of low-output oil fields, greatly reducing early-stage project investment and daily operating expenses.
2. Modular & Movable Structure
The whole refinery adopts segmented modular prefabricated design, supporting integral relocation and migration. It can follow the service cycle of small oil field sites, making it ideal for temporary and remote crude mining operation scenarios.
3. Strong Crude Oil Adaptability
It supports processing of both light crude oil and high-viscosity heavy crude oil. The system can switch adaptive process parameters according to different API gravity values of raw crude, allowing flexible adjustment of each oil product output ratio to meet diverse production needs.
4. Energy-saving Waste Heat Utilization
Flue gas waste heat generated during furnace heating is fully recycled to preheat raw crude oil. This greatly reduces external fuel consumption, cuts overall system energy loss and lowers long-term production costs.
5. Fast On-site Installation & Commissioning
All core modules are prefabricated and assembled in the factory. After equipment arrives at the project site, only simple pipeline connection and electrical wiring are required. It drastically shortens construction cycle and enables rapid project put-into-operation.
Application Scenarios
1. On-site Refining for Medium & Small Onshore Oilfields
Realize on-site fractionation of crude oil exploited from small oil fields. Produced diesel and fuel oil can be directly used for local oilfield equipment operation, saving massive crude oil outbound transportation costs.
2. Crude Processing for Remote Inaccessible Mining Areas
For remote mining zones with poor transportation conditions, the compact mini refinery replaces large-scale refining plants, completing localized conversion and value upgrading of crude resources.
3. Oil Field Pilot Test & Data Verification Project
Used for fractional distillation experiments of newly exploited crude oil. It accumulates practical operational data and provides reliable technical basis and design references for the construction of subsequent large-scale refining projects.
4. Auxiliary Refining Project for Overseas Small Petroleum Exploitation
Supplies modular complete-set equipment for small oil and gas producers in Africa, Southeast Asia and other regions, satisfying local small-capacity crude oil processing demands.
5. Resource Regeneration of Oil Depot Slop Oil & Residual Crude
Process tank bottom heavy crude and slop oil accumulated in oil depots. Effective fractionation recovers multiple usable fuel fractions, realizing harmless treatment and resource recycling of waste oil materials.

FAQ
Q1: What is the standard processing capacity of this mini refinery?
A: The standard model achieves a daily crude oil processing capacity of 5 to 30 tons. We support full non-standard customization to adjust equipment parameters according to customers' actual crude output scale.
Q2: Can the refined oil products be directly sold as commercial finished oil?
A: The output oil fractions are primary straight-run products. To meet commercial finished oil standards, further deep refining processes such as desulfurization and decolorization are required. The crude fractions can be directly applied for industrial boiler combustion and generator power generation.
Q3: What pretreatment work is required for raw crude oil?
A: Simple filtration is needed to remove large particulate impurities. The built-in desalting and dehydration unit handles conventional crude contaminants. For high-salt and high-viscosity heavy crude, enhanced pretreatment procedures are required to prevent rapid salt scaling inside the tower.
Q4: What auxiliary utilities does the equipment need for operation?
A: The system requires supporting fuel heat source, circulating cooling water and 380V explosion-proof power supply. Usable heat sources include self-produced residual oil, natural gas and biomass fuel.
Q5: What is the continuous operation cycle of the unit?
A: With qualified raw material pretreatment, the equipment can run continuously for 20 to 35 days before requiring shutdown for decoking and descaling maintenance. Higher impurity content in crude feedstock will shorten the maintenance cycle.
Production Process Flow
Crude oil feeding → Electric desalting & settling dehydration pretreatment → Tube furnace gradient heating → Atmospheric tower fractionation to separate naphtha and light diesel fractions → Atmospheric residual oil delivered to vacuum tower → High-vacuum distillation to extract heavy diesel and fuel oil → Multi-stage heat exchange & cooling for each side-draw fraction → Classified storage in corresponding finished oil tanks. Non-condensable tail gas generated in the process is recycled as heating fuel for the tube furnace, and heavy tower-bottom residual oil is discharged externally.
