Static Reactors are used to intensfy chemical processes chemical, petrol, food, pulp and paper and other industries.

How it works

Liquid is pumped with a certain pressure into the Static Reactor which produces a myriads of bubbles (caverns). These caverns are collapsing immediately after they are produced. This process (cavitation) creates a local pressure inside a bubble up to hundreds bars (locally) and destructs long molecular chains. As the result all components (oil, water, additives, ..) are properly mixed in a form of stable emulsion.

Multi-stage turbulent sections are designed inside the reactor in order to create conditions for the cavitation. Due to media viscosity&density are different, static reactors for non-standard liquids are designed individually.

Normal working pressure for static reactor is 12…20 bars depending on oil or other media type.


Static reactors are designed for improving oil and oil-based products by the decrease of viscosity, flash point and pour point.
Being a very effective unit for the mixing it amplifies an impact of additives which are normally used for improving the quality of oil, Heavy Fuel Oil (HFO, mazut) and other products.
Another function of static reactor is an improved mixing process of liquids and gases. For example, ozone is added to a water or other liquid is well mixed with with bubbles size below micrometers. Water-ozone mixture create conditions for the water decontamination.
Oil, passed through the static reactor, has higher output of light fractions like benzin and diesel. Oil and oil-based fuels becoming uniform what improves combustion characteristics.



Major applications are:

  • Special applications – dissolving liquid additives and gases in oil, micromilling of solid particles which may exist in water, oil or other liquids.
  • In oil industry– for increasing light oil fractions output, reducing consumption of catalysts, dissolving liquid and gazeous additives, etc.
  • In combustion systems – for improving combustion characteristics, reducing sledging, etc.
  • Decontamination – reactors intensify mixing of water and other additives decreasing the consumption of different catalysts.

Depending on oil characteristics static reactor may reduce oil viscosity up to 30%, reduces pour point from -6 deg C till -16 deg C, increases output of light fractions on 2…3% or more for different types of oil. Watered oil processed in DEWA-OIL becomes uniform and does not include “water lenes”, produced water-oil emulsion is stable for a long period.
