1、 Petroleum and refined oil storage and transportation (the most core application in the oil and gas industry)
1. Crude oil storage tank area
Large external floating roof vertical carbon steel storage tanks are used for crude oil receiving, transit, and strategic reserves in refineries, oil depots, and ports.
2. Finished oil storage (dome roof/inner floating roof tank)
Diesel, fuel oil, kerosene, aviation kerosene, lubricating oil, residual oil, heavy fuel oil;
Gas stations, enterprise owned oil depots, and transfer storage tanks at pipeline terminals.
3. Supporting medium tanks for oil and gas fields
Oil production platform/gathering station: produced wastewater tank, buffer settling tank, demulsifier storage tank, ethylene glycol (antifreeze) storage tank.
Medium characteristics: The oil has good compatibility with carbon steel; The inner wall is equipped with anti-static anti-corrosion coating, static grounding, breathing valve, and flame arrester.
2、 Thermal power generation, cogeneration (power plant utilities)
1. Fuel storage
Boiler ignition match oil tank, backup fuel heavy oil/residual oil vertical storage tank;
2. Water treatment system storage tank
Demineralized water, industrial clean water, and fire water storage tanks;
Desulfurization system: limestone slurry buffer tank, process wastewater tank, emergency storage tank for accidents;
3. Pharmaceutical storage
Ammonia water, hydrazine, scale inhibitors, etc. (corrosive media require inner wall anti-corrosion or lining);
4. Oil system
Turbine lubricating oil and sealing oil storage tanks.
3、 Coal chemical and coal to energy projects
1. Coal to oil and coal to olefin
Intermediate storage tanks for raw oil, naphtha, crude diesel, and product oil products;
2. Coal to methanol, ethylene glycol, and synthetic ammonia plants
Crude methanol, refined methanol, and ethylene glycol atmospheric pressure vertical carbon steel storage tanks;
3. Process buffering and waste liquid collection
Process condensate tank, oily wastewater buffer tank, accident wastewater collection tank;
4. Common media
Circulating water, fire water, fuel buffer tank.
4、 Biomass energy industry
Storage tanks for biodiesel, crude bio oil raw materials and finished products;
Biomass gasification supporting tar storage tanks and circulating washing solution storage tanks;
Diesel backup fuel tank for biomass heating plant area.
5、 New energy storage and new energy supporting scenarios
1. Molten salt energy storage (solar thermal power plant)
Low temperature molten salt, high-temperature molten salt buffer/storage tank (for medium and high temperature conditions, carbon steel such as Q345R containers are selected, with supporting insulation and anti-corrosion);
2. Supporting facilities for wind and solar power stations
Backup diesel storage tanks, fire water storage tanks, and water treatment agent storage tanks for power stations;
3. Public works of hydrogen production plant
Demineralized water tank, circulating water tank, and tank washing wastewater collection tank; Liquid organic hydrogen storage medium transfer tank (under normal operating conditions).
6、 Supporting application of natural gas industry chain
Supporting facilities for urban gate stations and LNG gasification stations:
Diesel backup fuel tank;
Ethylene glycol aqueous solution (natural gas dehydration antifreeze) storage tank;
Gas condensate collection tank;
Production wastewater and rainwater accident collection tank.
Gaseous natural gas and liquid LNG cannot be directly stored in ordinary carbon steel atmospheric pressure vertical tanks.
