NSTDA and the Royal Thai Naval Dockyard have been researching, designing and producing continuous bio-diesel producing machines whose production system uses tubular reactor technology. Using such a reactor, the system produces 2,000 liters for one machine and 20,000 liters per day for the second reactor, which is faster than a stirring type
or the general batch process. The reactor designed by the research team helps to create turbulent flow mixing which allows even reactions between materials and chemicals in less time. Also, it separates glycerin from bio-diesel efficiently, giving a standardized product. Moreover, the continuous bio-diesel production system does not release polluted water because it cleans the bio-diesel output by using chemical compounds to attract the waste, which helps to lower the cost of polluted water treatment. Besides this, the system also reuses methanol which lowers the cost of chemicals used. Overall, this production system is a suitable prototype for the bio-diesel manufacturing industry.
