Demulsifier

Crude oil flowing from wells contain fair amount (often 20-30%, sometimes up to 60-65%) of water with dissolved salts from basis point up to 1-2%. This significantly increases viscosity of crude oil, generates stable emulsion and makes the oil inadequate for refining and transportation. Water produced together with oil is usually in very unusual state, i.e. it is spread in oil in the form of droplets (emulsified form). Less the size of droplets, more stable the emulsion. One of the main reasons of emulsion stability is also the presence of resin, pyrobitumen, paraffin, and other oil admixtures like glycerine, microcrystal of paraffin, ceresin in crude oil. These substances generate quite firm and thick (protective films) on the surface of water and solid particles thus preventing merging of water drops and solid particles and their spontaneous segregation from oil. At present physical, thermal, physico-chemical, electrical and combined methods of oil emulsion breaking are used for oil dehydration and oil desalting. One of the widelyused and most effective methods is physicochemical combined method using chemical reagents demulsifiers. Demulsifiers are substances with high surface activity. They are concentrated in interfacial areas of oil emulsion, break protective films covering solid particles, water droplets and neutralise their electric charges. After this, small droplets will merge into bigger drops under the influence of mutual attraction, loosen and segregated from oil.Oil demulsifying is carried out in oil field and oil refinery plants.

At present “KARVAN-L” company tries to provide integrated work cycle: – development production supply and implementation of produced demulsifiers together with consumer. Demulsifier Karvan-200 is designed for oil dehydration and desalting in gathering system and oil treatment plant. Reagent can also inhibit corrosion processes.Demulsifier Karvan-201 is designed for separation of both light and heavy crude emulsion. This reagent is the composition of macroglycols and nitrogen-bearing surfactants in organic solvent environment
Demulsifier discharge per 1 ton crude is 10-60gr. Dosage depends on emulsion stability, treatment temperature, water separation period and desired depth of oil processing. Optimum dosage and demulsifier application process ensuring necessary results can only be defined as per test results carried out in practical use sites.

We offer desalter demulsifiers based on our crude oil demulsifier formulations.
These products are used in refinery desalter units, which often handle varying blends of crude oil.
Our desalter demulsifiers are proven to perform across a wide range of feedstock qualities, improving efficiency in crude oil washing and salt removal.

The water-soluble reverse-demulsifiers can be used to treat contaminated cutting oils, but also for other industrial oil-in-water emulsions, as can be encountered in various industries. Clarification of the waterphase is the main objective.
Coalescence agents are used to destabilise this type of emulsions by increasing the size of the oil-droplets present.
They can be used together with flocculation agents to accelerate the separation process and/or to improve overall clarification.

A demulsifier is a surfactant that breaks up an emulsion. The demulsifier mainly destroys the emulsion by partially replacing the role of the stable film. Used as a dehydrating agent, it can remove the water in crude oil and heavy oil, so that the water content can meet the requirements; it can reduce the viscosity of crude oil when used in oil wells, so that the oil wells will not be blocked. It is obtained by polymerization of fatty alcohol, propylene oxide and ethylene oxide. Soluble in water, light yellow or milky white viscous liquid. Soap smell. Freezing point 25 ~ 40 ºC. Hydroxyl value 60 mg potassium hydroxide/g. , the aqueous solution is milky white.

Cutting oil emulsions are so called (oil-in-water) emulsions.
Emulsifiers have been deliberately added to ensure a good mixture of the oil and water for cooling purposes. Used cutting oils contain, of course, a lot of contaminations like metal particles.
In order to recover the oil from the used waste cutting oil or to reduce the volume, OWT has water-soluble reverse-demulsifiers.
Especially when a certain batch of such kind of waste has to be treated, we prefer that you send us a representative sample (approx. 3-5 ltrs) of this emulsion together with a description of the process conditions: treatment-temperature, settling or mechanical (centrifuge) separation process and so much more.
In our laboratory we will then select the best cost-performing demulsifier to treat this particular batch, and advice you what goals are obtainable within the shortest possible time limit. This evaluation will be free of charge.

The label (Waste Oil) covers a variety of industrial (water-in-oil) emulsions.
Waste Oil (or Slopoil) can be used motor oils (crankcase oils), tankbottoms at refineries or other storage facilities, contaminated fuel oils, waste from chemical factories and many more. These are all stable mixtures (emulsions) of oil and water, often containing also other impurities like sediments and insoluble salts.
Formulated from surface active compounds, wetting agents, wax dispersants and other additives, the OWT waste oil demulsifiers are often developed tailor-made to recover the maximum of oil and remove the maximum of water and solid impurities in the shortest feasible settling time.
