Petrochemical industry

Introduction

In the petrochemical industry, filtration equipment is widely used in crude oil processing, oil refining, lubricant production, sewage treatment, catalyst recovery, chemical product production, petroleum coke and asphalt processing, additive production, storage, transportation and loading and unloading, etc. Its main functions are to remove solid impurities, separate liquids and solids, protect equipment, improve product quality, and meet environmental protection requirements.

Applications

  • Crude oil processing: filtering solid impurities (such as silt, metal particles, paraffin, etc.) in crude oil, and separating oil-water mixtures
    Equipment selection: filter press, bag filter.
    Function: improve crude oil purity and reduce wear and blockage of subsequent processing equipment.

  • Refining process: filter catalyst particles (such as catalysts in catalytic cracking and hydroprocessing) and separate solid residues produced in the refining process.
    Equipment type: automatic backwash filter, candle filter, closed plate filter, etc.
    Function: protect downstream equipment and ensure product quality.

  • Wastewater treatment: filter oily wastewater generated in refining and chemical processes.
    Equipment type: filter press, belt filter press, etc.
    Function: achieve wastewater discharge standards and reduce environmental pollution.

  • Catalyst recovery: filter and recover catalysts used in refining and chemical processes.
    Equipment type: candle filter, filter press, etc.
    Function: improve catalyst utilization and reduce production costs.

  • Chemical product production: Filter impurities in chemical raw materials (such as polymers, resins, solvents, etc.) and separate solid particles in chemical products.
    Equipment type: filter element filter, bag filter, candle filter, etc.
    Function: Ensure the purity and quality of chemical products.

  • Additive and auxiliary agent production: Filter impurities in petrochemical additives (such as antioxidants, rust inhibitors, emulsifiers, etc.).
    Equipment type: precision filter, bag filter, etc.
    Function: Ensure the purity and performance of additives.

  • Storage and transportation: Filter impurities in oil products during storage and transportation.
    Equipment type: pipeline filter, basket filter, etc.
    Function: Ensure the cleanliness of oil products during storage, transportation and loading and unloading.
