Types of Demulsifier, Oil Soluble Demulsifier, Water Soluble Demulsifier
Types of Demulsifier
There are two different types of demulsifiers are available in the market. Oil soluble demulsifier for demulsification and water soluble demulsifier. Oil soluble demulsifier is organic formulation soluble in crude oil, xylene and toluene and creates the emulsion process for water in oil and oil in water at room temperature. It gives better performance if the temperature increases above certain degree.
Water soluble demulsifier is the organic surfactants solution with water and soluble in crude oil for Demulsification process of oil in water at room temperature. Water soluble emulsion breaker soluble in the mixture and start the emulsion process immediate. These demulsifiers are non hazardous and non-toxic. In petroleum crude oil production industry the demulsifier must be biodegradable so that the water soluble demulsifier doesn’t contain any phenolic contain on removal.
Demulsifier is the organic compound and need to keep away from direct sunlight. Direct human contact of demulsifier should be avoided. To avoid hazardous effect of demulsifier, the goggles and gloves should wear for safe handling. The spillage can be handled with dry absorbent like sand, sawdust etc. On ingestion / eye contact with the product, medical attention should be sought immediately. Chemicals for Drilling Fluids production include dispersants, emulsifiers, wetting agents, biocides, defoamers, corrosion inhibitor, and flocculants. For Cementing and Stimulation, polymers, surfactants, clay control additives, friction reducers, etc. are regularly used. For Oil Production, drag reduction agents, flow improvers, defoamers, sulfite scavengers, etc. are the key chemicals.
