Features
Crude-oil desalting-dehydration pretreatment unit:
The petroleum refinery plant is equipped with a two-stage electric desalting and dehydration system. Under conditions of 110-130 ℃ and high-voltage electric field, salts, moisture and mechanical impurities in crude oil are removed. The water-removal rate and salt content of crude oil are controlled at extremely low levels, which effectively protects heating furnaces and hydrotreating reactors and extends the long-term service life of the plant.
Atmospheric-vacuum distillation and fractionation unit:
Desalted crude oil recovers waste heat from diesel and residual oil via a heat-exchange network before entering the atmospheric heating furnace and atmospheric fractionation tower. Naphtha is obtained at the tower top and straight-run diesel is drawn from side-draw outlets. Atmospheric residual oil flows into the vacuum furnace and vacuum fractionation tower to produce wax oil from side draws and heavy residual oil at the tower bottom, realizing accurate cutting of multi-component fractions.
Deep diesel hydrofining unit:
Straight-run diesel of the petroleum refinery plant undergoes high-pressure hydrodesulfurization under hydrogen partial pressure of 6.0-8.0 MPa and reaction temperature of 320-360 ℃. Sulfur and nitrogen impurities are deeply removed. The sulfur content of finished diesel is controlled below 8 ppm, exceeding Euro-V standards, with high cetane number and low polycyclic-aromatic-hydrocarbon content to satisfy operating requirements under low-temperature conditions.
Dry-gas hydrogen production + naphtha hydrotreating unit:
Self-produced C1~C4 dry gas is used to produce high-purity hydrogen through steam reforming, shift reaction and PSA pressure-swing adsorption for all hydrotreating units of the whole plant. Naphtha undergoes medium-low-pressure hydrotreating to remove sulfur, olefins and heavy metals. After refining and blending, it meets Euro-V gasoline standards with complete self-production and self-consumption of hydrogen.
Environmental-protection recovery system:
The petroleum refinery plant is equipped with MDEA amine-liquid desulfurization plus two-stage Claus sulphur-recovery unit. Hydrogen-sulfide by-product from hydrotreating is recovered into solid industrial sulphur, and tail gas reaches discharge standards after hydro-absorption treatment. A light-hydrocarbon-recovery unit separates liquefied petroleum gas and fuel dry gas; dry gas is recycled for hydrogen production and boilers to realize resource-based utilization of by-products.
Advantage
Full-process clean production:
A complete closed-loop covering primary distillation, dual hydrotreating, hydrogen production and sulphur recovery realizes deep desulfurization and denitrification. It produces Euro-V-grade ultra-low-sulfur oil products complying with stringent environmental-protection and oil-quality standards.
High energy self-sufficiency:
Self-produced dry gas and vacuum residual oil of the whole plant are used as fuel. Self-built utilities including boilers, power supply, hydrogen-production, air separation and flare systems greatly reduce consumption of purchased fuel and media and cut production and operation costs.
Internal recycling of hydrogen resources:
The dry-gas hydrogen-production unit supplies high-purity hydrogen for two hydrotreating units, achieving hydrogen self-sufficiency, lowering purchased-hydrogen cost and improving overall plant economic benefits.
High-value recovery of by-products:
By-products such as liquefied petroleum gas, wax oil and industrial sulphur are recovered for external sales; dry gas is recycled as fuel to realize full resource utilization and expand profit sources for projects.
Manufacturing assurance to ASME standards: Core pressure vessels are designed and manufactured in accordance with ASME specifications with U-stamp certification. Process piping complies with ASME B31.3, delivering high equipment quality and safety reliability suitable for overseas engineering-project construction requirements.
Application Scenarios
- Full-process construction project for medium-and-small-sized refineries: Build a complete refinery production line covering pretreatment, distillation, hydrotreating, hydrogen production and sulphur-recovery with crude oil as feedstock to produce Euro-V-grade finished oil products.
- High-sulfur crude-oil deep-processing project: For crude oil with relatively high sulfur content, deep hydrodesulfurization and sulphur-recovery are adopted to produce low-sulfur clean fuels and realize resource-based utilization of high-sulfur crude oil.
- Regional finished-oil supply project: Ultra-low-sulfur gasoline and diesel are produced locally to meet regional fuel-supply demands and shorten logistics-distribution distance for finished oil products.
- Waste-oil and pyrolysis-oil refining project: Process waste engine oil, tire pyrolysis oil and other oil feedstocks, and produce qualified oil products via hydrofining to extend the waste-oil resource-recovery industrial chain.
- Petrochemical-feedstock supporting-processing project: Produced naphtha, liquefied petroleum gas and wax oil can serve as feedstock for petrochemical units, providing basic raw-material sources for downstream chemical production.

Q4: What is the hydrogen source for the plant?
A: An on site dry gas hydrogen production unit adopts self produced C1~C4 dry gas for high purity hydrogen production via steam reforming and PSA pressure swing adsorption, realizing hydrogen self sufficiency without external hydrogen purchase.
Q5: What about the construction cycle and investment scale of the plant?
A: Adopting modular skid mounted construction, core pressure vessels are pre fabricated off site according to ASME standards, which greatly reduces on site assembly work and shortens the construction cycle. Specific investment shall be defined at the budgeting phase according to project scale.
