Features
Continuous crude-oil heat-exchange-heating-fractionation process:
The small crude oil refinery plant adopts typical continuous workflow of "crude-oil heat exchange-heating furnace-atmospheric tower-condensation & cooling-product separation". Crude oil is pre-heated to 200-220 ℃ through heat-exchange network by sequentially exchanging heat with overhead oil-gas, diesel fractions and heavy-oil fractions. Waste heat from products is fully recovered to cut fuel consumption of the heating furnace.
Simplified electric desalting & dehydration unit:
Equipped with simplified electric desalting facilities, the small crude oil refinery plant removes most moisture (≤0.5%) and salt content (≤5 mg/L) from pre-heated crude oil. It prevents scaling and corrosion of heating furnaces and towers to ensure long-term stable plant operation.
Gradient-heating system of atmospheric heating furnace:
Desalted crude oil is heated to 360-370 ℃ in the atmospheric heating furnace to partially vaporize gasoline and diesel components and form gas-liquid two-phase mixture. Furnace tubes are made of Cr5Mo material with excellent high-temperature and corrosion resistance to satisfy heating load requirements.
Multi-component cutting system for atmospheric distillation tower:
The heated mixture enters the atmospheric distillation tower. Straight-run gasoline is condensed and obtained at tower top; atmospheric diesel (light & heavy diesel) is drawn from side-draw outlets after stripping in stripping tower; heavy fuel oil is discharged from tower bottom, realizing accurate separation of multi-component fractions.
DCS/PLC automatic control system:
Centralized control of temperature, pressure, flow rate and liquid level is configured. Automatic monitoring and adjustment are applied for furnace outlet temperature and tower-bottom liquid level to avoid heavy-oil coking or tower flooding accidents and guarantee continuous and stable production.
Advantage
Mature and reliable process:
Adopting traditional atmospheric distillation technology, it features proven technique, simple operation, low maintenance cost and high running stability with low technical threshold for operators.
Controllable investment cost:
Without vacuum distillation system, the small crude oil refinery plant has fewer equipment items. Manufacturing and procurement costs are well-controlled, which fits upfront investment of medium-and-small-scale crude-oil processing projects.
Reasonable product portfolio:
The yield of three products (straight-run gasoline, atmospheric diesel mainly light diesel supplemented by heavy diesel, heavy fuel oil) matches feedstock properties. Products can be sold directly or used as feedstock for downstream units with favorable economic benefits.
Significant energy-saving optimization: The crude-oil heat-exchange network recovers product waste heat to greatly reduce heating-furnace fuel consumption. With 8000 annual operating hours, it achieves high production efficiency and low per-ton-oil operating cost.
Easy-to-maintain equipment:
Free from complex high-pressure hydrotreating and vacuum systems, the small crude oil refinery plant has key equipment such as pumps, heat exchangers and towers with simple structures. Daily maintenance is convenient and spare parts enjoy high universality.
Application Scenarios
- Medium-and-small-scale primary crude-oil processing project: Build atmospheric distillation units with small-volume crude oil as feedstock to produce basic products including straight-run gasoline, diesel and heavy fuel oil.
- On-site crude-oil processing project for remote areas: Carry out on-site atmospheric distillation in regions with poor transportation access where crude-oil outbound delivery is difficult. It cuts crude-oil logistics cost and obtains fuel oil products locally.
- Feedstock-preparation project for downstream units: Produced straight-run gasoline and diesel can serve as incoming feed for secondary-processing units such as catalytic reforming and hydrofining.
- Fractionation-processing project for oil traders: Purchase crude oil for on-site distillation and fractionation, produce various distillate oil products for sales and conduct deep-processing crude-oil trading business.
- Regional fuel-oil supply project: Produce straight-run gasoline and diesel to satisfy local fuel demands, shorten logistics distance of finished oil and guarantee regional energy supply.
Packing & Shipping
- Main equipment including atmospheric distillation tower, heating furnace, electric desalter, heat exchangers and condensers are treated for anti-corrosion and anti-rust. Dust-proof protective covers are installed for all flange nozzles. Tall towers are manufactured in segmented sections with reinforced bases for fixed bare-pack transportation to ensure structural stability during ocean shipment.
- Tower trays, sealing gaskets, special maintenance tools, spare wearing parts, valves and pipe fittings 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 and extra-large 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 kinds of crude oil can this small crude oil refinery plant process?
A: It can process conventional light to medium crude oil. Equipped with simplified electric desalting dehydration facilities, it can handle salt and water bearing crude oil. Applicability for heavy high viscosity crude oil shall be determined after feed stock property evaluation.
Q2: What products can the plant produce?
A: It can produce three products: straight run gasoline, atmospheric diesel (light & heavy diesel) and heavy fuel oil. Straight run gasoline can be used as naphtha or gasoline blending component; heavy fuel oil can serve as fuel oil or downstream feedstock.
Q3: What is the capacity range of the equipment?
A: The standard model reaches an annual processing capacity of 100 000 tons with hourly throughput of approx. 12.5 m³/h. Non standard customization is available according to customers' actual capacity requirements.
Q4: What heating method does the plant adopt?
A: It uses atmospheric heating furnace with Cr5Mo high temperature resistant furnace tubes. Crude oil is heated to 360 370 ℃ for partial vaporization and fractionation of gasoline and diesel components.
Q5: Can the produced diesel be directly used as vehicle fuel?
A: The output is straight run atmospheric diesel as basic distillate product. Secondary processing such as subsequent hydrofining is required to meet vehicle grade diesel standards. It can be directly applied as industrial fuel or downstream feedstock.
