Emulsions are created by the presence of soap which in turn is generated by Caustic catalysts such as sodium methylate in combination with fatty acids and indirectly by means of hydrolysis. The severity of such emulsions is a direct result of the level of fatty acid and moisture present in the feedstock.
Emulsions have a direct effect on the reaction time needed to reach specification in particularthe monoglyceride specification. This soap content will also cause problems with crude glycerol storage in cold climates.
Acceptance of emulsions leads to costly secondary reprocessing. All of this can be avoided and allow increased throughput,simplified processing and a better
The cost of Biodiesel production relies in part on the recovery of excess Methanol used in the manufacturing process. Currently most operators use heat and vacuum for recovery. The current temperatures to recover Methanol under vacuum leads to vacuum control problems and difficulty in condensing the Methanol. Current best practice leads to a recovery shortfall of 20%. This cost along with the need to dry the wet Methanol recovered leads to significant avoidable costs.
Ceimici Novel innovative processing technology leads faster processing and 100% Methanol recovery.
The quality of the Glycerol produced as a coproduct is entirely governed by the level of Soap produced and the method chosen to onprocess the Glycerol to recover the excess Methanol.
For optimum processors, the Glycerol content is 80% while other processors using Waste Oils can end up with Glycerol contents of 60%.
The balance of Crude Glycerol is made up of Salt, MONG,Ash and Water.
Ceimici Novel's technology produces Glycerol in excess of 98% with no Salt, MONG or Ash.
To make Soap you require Free Fatty Acid. A caustic component is also required. Elimination of one or the other removes the Soap issue from the process. Fatty Acid is always a component of Triglycerides and can only be minimized. However, the presence of moisture in the feedstocks is an important consideration. Catalysts used in the Transesterification process can also Catalyze the Hydrolysis of Triglycerides and generate Fatty Acid.
Since Fatty Acid and Moisture are components of the feedstock, the only real solution is the choice of a Catalyst. Smart Catalyst does not react with Fatty Acid to make Soap and does not Catalyze the Hydrolysis of Triglyceride to make Fatty Acid.
All downstream problems in the manufacture of Biodiesel disappear when this Soap is eliminated.
