Features
Atmospheric-vacuum distillation pretreatment unit:
The oil refinery and petrochemical plant is equipped with two-stage electric desalting and dehydration modules to remove chloride salts, free water and mechanical impurities from crude oil. After being heated by heat exchange, crude oil flows into the atmospheric furnace and atmospheric fractionation tower to separate naphtha, kerosene and straight-run diesel. Heavy oil from the bottom of atmospheric tower goes to the vacuum tower for vacuum fractionation to produce wax oil and vacuum residue.
Naphtha hydrofining unit:
Mixed light and heavy naphtha is fed into fixed-bed hydrotreating reactors for desulfurization, denitrification and olefin saturation. The sulfur and nitrogen contents of refined naphtha are controlled at an extremely low level, which effectively protects downstream noble-metal reforming catalysts and ensures long-term stable operation of the plant.
Combined catalytic reforming and isomerization unit:
Refined heavy naphtha passes through multi-stage reforming reactors. Under the effect of platinum-based catalysts, dehydrogenation, cyclization and isomerization reactions take place to generate high-octane gasoline blending components with hydrogen as by-product. Light naphtha improves octane number via low-temperature isomerization. High-grade clean gasoline is produced without adding metallic octane boosters throughout the process.
Diesel hydrofining and isodewaxing unit:
Straight-run diesel undergoes first-stage deep hydrodesulfurization and second-stage shape-selective isodewaxing. Long-chain normal-paraffin wax molecules are isomerized into branched-chain alkanes, which greatly reduces cold filter plugging point. It produces standard summer-grade diesel and low-pour-point winter-grade diesel respectively for application in frigid regions.
Advantage
Integrated full-process layout:
The oil refinery and petrochemical plant integrates the whole workflow ranging from crude oil pretreatment, atmospheric-vacuum fractionation to hydrotreating, reforming and dewaxing. Multiple end-use oil products can be manufactured after raw materials are fed once, reducing intermediate material transfer and improving overall production efficiency.
Diversified product portfolio:
The oil refinery and petrochemical plant can simultaneously produce motor gasoline, ultra-low-sulfur diesel, jet fuel, heavy fuel oil and other products. The product mix can be flexibly adjusted according to market conditions to enhance the project's capability against market fluctuations.
Recycled hydrogen resource:
High-purity hydrogen by-produced from the catalytic reforming unit is recycled for each hydrotreating unit of the whole plant to realize hydrogen self-sufficiency. It cuts the cost of purchased hydrogen and lowers the processing cost per ton of oil.
High-standard environmental-protection design:
Deep desulfurization and denitrification are implemented. Sulfur-containing wastewater is treated in a centralized manner while tail gas and vented gas are recovered and treated. All emission indicators meet strict environmental-protection standards, making it suitable for construction in industrial parks with rigorous environmental supervision.
Application Scenarios
- Construction project for medium-and-small-sized refining complexes: Build modular skid-mounted refineries with conventional crude oil as feedstock to produce end-use fuel oil such as gasoline and diesel as well as jet fuel.
- Regional finished-oil supply guarantee project: For regions with concentrated fuel demands, oil products including motor gasoline and low-pour-point diesel are produced locally to shorten logistics distance of finished oil and guarantee regional energy supply.
- Supporting processing project for chemical feedstocks: Intermediate products such as reformate aromatics and hydrogen can be used as petrochemical feedstocks to supply downstream chemical units and extend the integrated refining-chemical industrial chain.
- Fuel processing project for extremely cold regions: Diesel isodewaxing technology yields low-pour-point diesel to satisfy oil demands for transportation vehicles and construction machinery under frigid weather conditions.
- Overseas medium-and-small-scale refining engineering project: Provide complete modular supply for resource-rich regions lacking refining capacity to realize local crude-oil resource utilization with fast plant construction.
Packing & Shipping
- Large pressure vessels including atmospheric-vacuum towers, reactors, fractionation towers and heating furnaces are treated for anti-corrosion and anti-rust. Dust-proof protective covers are installed for all flange nozzles. Tall towers and large-size reactors are manufactured in segmented sections with reinforced bases for fixed bare-pack transportation so as to guarantee structural stability during ocean shipment.
- Precision electrical automatic-control components such as DCS control cabinets, SIS safety instruments, on-line analytical instruments and sensors are independently packed in shock-proof and moisture-proof solid-wood cases. Ocean-shipping marks including This Side Up, Moisture Proof and Fragile are printed on cases to prevent moisture-induced damage during long-distance transportation.
- Tower trays & packings, catalysts, sealing gaskets, 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 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 along with goods: PID process flow diagrams, equipment assembly drawings, pressure-vessel inspection reports, operation & maintenance manuals, catalyst loading schemes, wearing-part lists and full-set customs-declaration documents.
FAQ
Q1: What kinds of crude oil can this oil refinery and petrochemical plant process?
A: It can process conventional medium light crude oil. Equipped with two stage electric desalting dehydration pretreatment, it can handle salt and water bearing crude oil. Enhanced front end pretreatment is required if raw crude oil contains excessive colloids and asphaltenes.
Q2: What end products can the plant produce?
A: It can produce various products including 92# / 95# grade motor gasoline, ultra low sulfur diesel (including low pour point diesel), jet fuel and heavy fuel oil. The product structure can be adjusted flexibly.
Q3: What about the construction cycle and investment scale of the plant?
A: Adopting modular skid mounted construction, its on site construction period is greatly shortened compared with traditional large scale refineries. The specific investment shall be determined in the feasibility study phase according to project scale and supporting utilities.
Q4: How long is the continuous operation cycle of the plant?
A: DCS centralized control and SIS safety interlock ensure long term stable operation. Scheduled shutdown for maintenance is carried out after thousands of hours of normal continuous operation. The exact cycle depends on feedstock quality and operating conditions.
Q5: What supporting utilities are required?
A: Fuel heat source, circulating cooling water, instrument air, process nitrogen and dual circuit power supply are required. Interfaces for environmental protection accessories such as sewage treatment and flare venting are reserved for the plant.
