R& D UNIT AT GEORGE SOUTH AFRICA.

Reduction of the production cost is the main issue of this technology being developed,so called ultrasound/jet reaction biodiesel production.

Biodiesel production cost comprises raw material cost, capital expenditures and operations cost.

Possibilities to reduce the operation  cost of biodiesel production

Use reactors with intensive process of heat-and-mass transfer and high reaction rate like
1.Ulrasound radiation
2.Cavitation reactors
3.Intensive mixing like jet-reactors (Not jet-mixing)

These 3 options was selected by Biofuelson an r&d compony in South Africa run by Org Nieuwoudt to do further work on it.

Over a period of two years a selection to Ultrasound was done with a compony in China called Hangzhou Success Ultrasonic Equipment.Biofuelson has an agreement to distribute these ultrasound units into Africa.

Jet reactors was been identify by Prof Leon Lorenzen from the university of Stellnboosch.Biofuelson then take this idea a step further and developed an jet reactor special for Biodiesel production.This reactor is very intensive mixing so that heat is developed while running the oil into the reactor.When oil come into the system at 30 degrease Celsius(normal outdoor temp in Africa) actually no more heat is needed for transesterfication .The jet reactor will developed its own heat and while mixing the heat will went up as long as you mixing the oil  .This is very positive for Africa with its low electricity capasitty.Also it makes it very attractive for rural areas.

The combination of these two systems can bring reaction rate down with 50%,and not only that transesterfication temperature can been done as low as 30 degrease celsuis.Normal mixing time is up to 90 min ,with these combination mixing time can been as low as 30 to 45 min.

Another benefit is because of the cavitation bubbles formed with the ultrasound the mass transfer is better and faster.This allow less chemicals like catalyst and methanol.Some reactions was done with 20% less methanol and up to 40% less catalyst(KOH),with very good results.See results.

Downstream purification will also be easier because of less catalyst.What you put into the oil ,must come out again?Less soaps  is also forming.Some test show that as little as 5 to 10 % water will be needed to clean the biodiesel.This small amount of water can be added back into the glycerol stream so there will be no  waste products.

Yet another benefit is the time of glycerol separation.This is also faster and one of the reasons for it is that less methanol is been used ,so glycerol separation is faster.

Conclusions.
In future it will be possible to do biodiesel production with about 25 to 30% less operation costs,these include electricity ,catalyst,methanol and time(labour)

On a 1000 lit /day unit it is a saving of about 45 cents /litre or  R450 /day ($60/day)
On a 20 day production /month it is a saving of R9000  ($1200)
On 300 working days it is a saving of R135,000 ($18000)

Ultrasound left(Glycerol separation)

This specific process was done at 30 degrease intake ,methanol 16% of oil volume and koh was 40% less of normal amount been used.Reaction time was 45 min.

Biofuelson will soon have this system on the market for a very low prise compare to international prises.

Units will be 1000 lit batch systems and continues systems will soon been developed from as low as 500 lit/hour and up.

Old batch systems can also easy upgraded to the Biofuelson system.

Biofuelson  also do consulty work
1.Optimazation of plants.
2.Specialsied in acid esterfication with fetlocks high in ffa.
3.Transesterfication
4.Glycerol neutralization.(split glycerol and take ffa back into biodiesel production)

5.Analise of biodiesel with a cheap field test system.
