Emulsion Breaking Chemicals (Degreasing Chemicals)

In industrial processes, water and oil combine (emulsify) in some cases. As a result, depending on which material is dispersed in which, either oil-in-water (o/w) or water-in-oil (w/o) emulsions are formed. In oil-in-water emulsions, the continuous phase is water, while in water-in-oil emulsions, the continuous phase is oil. Both types of emulsions may contain different dishware (solids, dirt, metal chips, emulsifiers, cleaners, soaps, solvents, etc.). Emulsion breaking chemicals are required to solve these problems.

Emulsions can be formed as a result of a wide variety of processes in different industries. Since the formation of emulsions is specific to the industry and process, the selection of emulsion breaker products is both difficult and requires laboratory tests. Oils are very variable in content, ranging from lubricants and machine oils, to soluble oils, rolling oils, animal fats, and sometimes aromatics.

Industries where emulsions are common include:

• Basic metal industries – steel hot strip mills, casting systems and aluminium.
• Automotive and machinery industry – use of waste oils such as lubricating oils, cutting oils, lapping pastes, abrasive fluids and special-purpose fluids in metalworking and metal parts manufacturing
• Oil refining industry – oil sludge from separator, tank bottoms and cream from coal plants
• Petrochemical industry – olefin cooling processes
• Textile mills/synthetic fiber industry – spinning mills
• Meat and food processing industry – degreasing plants, dairies, breweries, canneries
• Paint, surface coating and adhesive industries
• Oils, fats and wax (:wax) industries
• Soap and detergent industries, including laundries
• Leather industry

Emulsion Theory and Emulsion Breaking Chemicals

To understand emulsion breakage, it is necessary to understand emulsion stability. The emulsion is generally stabilized by applying one or more of three basic processes; ionization, adsorption and frictional touch.

Ionization is provided by surfactant chemical agents in the system. Surfactants generally carry ionic charges and seek oil-water interfaces on the surface of emulsified droplets.

Adsorption stability is provided by small particles that are adsorbed on the oil-water interface and strengthen the interface film. The dispersed droplets cannot coalesce due to the interference and shielding effect of these solids. There may also be electrostatic charges, which can play an important role in emulsion stability.

When the oil and water phases are mixed together, frictional stability occurs on the touching surfaces. A very vigorous mixing is required for the emulsion to form. In this case, the fusion of the oil is prevented because the water or oil does not drain at the speed required for adhesion between the particle surfaces. In this order, electrostatic charges can occur and these charges tend to accumulate at the oil-water interface. This ensures the formation of a stable emulsion by repelling the emulsified charged droplets.

Emulsion Crusher: Emulsion Treatment

Oil separation can be divided into three basic processes; chemical, mechanical and thermal. All elements of these three processes are necessary for effective emulsion separation.

Emulsion Breaker: Chemical Treatment

Chemicals are widely used to treat oily wastewater, as well as to make mechanical treatment and separation more effective. In the dissolution of emulsions, the steady state factors are neutralized and the emulsified droplets are allowed to coalesce. The electrostatic charges in the emulsified droplets are neutralized by the addition of oppositely charged chemicals. SoleChem Engineering Chemistry ReddFloc® series emulsion breakers provide this counterload and are often combined with mechanical or thermal treatment to provide the best treatment.

Mechanical Treatment

Mechanical treatment of emulsions, dissolved air flotation (: Dissolved Air Floatation, DAF), induced air flotation (: Induced Air Floatation, IAF) and special separators called corrugated plate interceptor (: Corrugated Plate Interceptor, CPI) in refineries and American Petroleum Institute (API) It includes processes such as precipitation in the separator.

Thermal Treatment

The thermal treatment of emulsions has two purposes. First, increasing the temperature reduces the viscosity of the mixture, so it is possible to accelerate the film flow and separate the water from the oil. Second, the increase in temperature allows for better chemical mixing and better neutralization of emulsion stabilizing chemicals. Thus, increasing the temperature of the emulsion helps to dissolve the emulsion. However, heating oil-in-water (oily waste) emulsions is less effective in breaking the emulsion than heating water-in-oil (waste oil) emulsions.
