DEMULSIFIERS FOR WASTE OIL TREATMENT 

Due to EPA environmental mandates and market competition, a cost effective chemical process to clarify waste oils is essential. Good dependable can be the determining factor if recycled oil is an economically useable fuel.

Midwest Custom Chemical, Inc. is a specialty manufacturer of demulsifiers utilized for used oil applications. MCC has a proven product line of demulsifiers covering almost every type of emulsion in this field. These products are specially formulated from surface active compounds, wetting agents, and other additives. The applications for these products include the following:

  • Soluble oils
  • Crankcase oils
  • Refinery slops
  • Industrial oils
  • Coal tar dehydration
  • Bunker Fuels
  • Tank bottom cleaning

Each demulsifier is developed to perform on a broad range of emulsion types. This versatility offers an advantage in that several types of oil can be treated, usually with only one type of demulsifier.

In case of extremely tight emulsions on which optimum performance cannot be achieved with existing products, MCC is always prepared to develop a "tailor made" chemical to solve these problems.

The used oil demulsification division has developed a proprietary de-ashing process which increases the value of the end product at a small chemical cost. The reduced ash percentage results in the used oil being a cleaner, more desirable fuel. This technology is proprietary, however on-site demonstrations can be arranged to exhibit the results on each company’s crankcase oil streams.

 

APPLICATION FOR OIL TREATMENT CHEMICALS

 

Test Procedure for Waste Oil Demulsification

TEST PROCEDURE FOR WASTE OIL DEMULSIFICATION

STEP    PROCEDURE

1.             Fill 250 ml graduated bottle with 150 ml used oil.

2 .             Heat bottle in a waterbath or oven to 160-180° F

3.             Add 2000 ppm demulsifier to the oil and shake for 20 seconds.*

4.             Place oil in waterbath or oven for 24 hours.

5.             Check oil every hour and see if there is a water break developing.

6.             After 24 hours check for BS&W.

*Additional samples can be tested at different chemical concentrations to determine the most optimum treatment for your application.
