Oil Refining

PETROLEUM REFINING

PROTECTION AND RELIABLE PROCESSES

In the petroleum refining industry, industrial filters function as criticalsafeguards for process efficiency.

They remove contaminants from crudeoil and feedstocks, protecting expensive catalysts and high-pressureequipment from fouling.

By ensuring product purity and reducingoperational downtime, advanced filtration systems are indispensable foroptimizing output and safety

Typical Applications

Petroleum refining is the process of converting crude oil into gasoline, diesel fuel, jet fuel, and chemical raw materials. Because crude oil itself contains sand, metal salts, and coke and catalyst powders produced during processing, filtration technology directly determines the safety of the plant's operations, the lifespan of the equipment, and the purity of the products.

Flow of raw materials and intermediate oil products （Hydrocarbon Processing）

The refining feedstock commonly contains fine coke powder, rustintroduced from upstream processes, and sand and silt inherent in thecrude oil. Because the hydrotreating reactor is filled with extremelyexpensive catalysts, these solid impurities easily adhere to the surface ofthe catalyst particles, forming a "fouling layer," which leads to a sharpincrease in system pressure drop.Industrial filters effectively prevent catalyst "poisoning" or bed cloggingby intercepting these micron-sized impurities under high-pressureconditions. This extends the continuous operating cycle of theequipment (from shutdown for cleaning to the next startup) from a fewmonths to several years, directly saving significant economic lossescaused by production downtime.

Gas and solvent circulation flow direction （Gas & Solvent Treatment）

During the repeated cycling of the amine solution to absorb hydrogensulfide, degradation products (thermally stable salts) are produced, andsolid particles from the system are absorbed. These impuritiessignificantly alter the surface tension of the amine solution, leading tosevere foaming, causing substantial loss of solvent with the gas, andreducing the efficiency of heat exchangers due to scaling.

The combination of mechanical filtration and activated carbonadsorption effectively removes solid and organic impurities from theamine solution. This not only ensures stable desulfurization efficiencyand avoidsenvironmental compliance risks, but also significantly reducesthe cost of replenishing chemical solvents.

Refining and storage of refined petroleum products (Product Finishing)

Petroleum products inevitably become contaminated with free water oremulsified water during processing and pipeline transportation. This is

particularly critical for aviation kerosene; if the water content exceeds

the limit, it can freeze in the low-temperature, high-altitude environment,

threatening flight safety. Industrial filters (especially coalescing

separators) utilize special media to capture tiny water droplets and

coalesce them into larger droplets, achieving efficient oil-water

separation.

It ensures the "clarity and transparency" of the finished oil products and

extremely high cleanliness standards (meeting NAS or ISO specifications),

preventing product rejection due to excessive moisture or impurities,

and directly safeguarding the refinery's brand reputation and market

competitiveness.
