  • Refinery Plant Cleaning

    Refinery plant cleaning refers to the use of chemical methods and chemical agents to achieve the purpose of cleaning equipment.Our chemical cleaning service includes passivation cleaning service,deodorant cleaning service,heavy oil cleaning service, and polythionic acid cleaning service.
  • Refinery Plant Cleaning

  • Passivation Cleaning Agent

  • Industrial Heavy Oil Dirt Chemical Cleaning

  • Deodorant Cleaning Agent

  • Ferrous Sulfide Flame Retardant Agent

  • We have designed our oil and gas refinery cleaning services to minimize downtime, while still effectively tackling the unique and difficult cleaning problems found in oil and gas facilities.
  • The passivation cleaning agent can dissolve ferrous sulfide in the device and undergo oxidation decomposition to generate water-soluble substances and a small amount of precipitation.
  • First Introduction

    During the refinery shutdown mainteance, the traditional steam purging is often adopted in heavy oil system, but chemical cleaning is a kind of technology of using cleaning agent to dispose heavy oil dirt, which is recycled in the temperature of 130-150℃,with catalytic diesel oil as the mother liquor. Because the industrial heavy oil cleaning agent has a strong penetration and decomposition effect, it has a strong affinity and decomposition effect on macromolecular hydrocarbons, even high C/H ratio of asphaltenes and colloid, making it achieve a good cleaning effect at low concentration (1.0-1.5%).

    Second Cleaning mechanism
  • Characteristics

    1.Good deodorant cleaning effect;
    2.Soluble in water, stable property and not volatile;
    3. Non-toxic and harmless, convenient and safe to use;
    4. No environmental pollution.

    Using Method

    1. Scope: applicable to the removal of stench caused by hydrogen sulfide, mercaptan, sulfide and other substances.
    2. Method: the product is mixed with water by 1:10, clean the system by spraying, soaking or circulating, and the cleaning time is 8 - 10 hours.
  • Features
