The Compact Production Unit (CPU) is a complete modular methyl ester production machine with the capacity of 8 000 t/year, ready for start-up after connection to the external tanks such as for methanol, oil, methyl ester, KM32 and G-phases, compressed air, external ventilation lines and electric power. The CPU features a continuous process system containing automatic electronic proportioning systems of the oil, catalyst and methanol dosing, unique propeller mixers/reactors, patented high-pressure static mixers, decanter tanks, vacuum distillation for the removal of excess methanol and methanol recycling back into the process.
The washing of the methyl ester is carried out by combination of adsorption and ion exchange resin beds. Washing water, steam and acids are completely avoided in the process. The CPU is a CE certified “Plug and Play” compact factory, tested under the supervision of SGS prior to delivery. CPU 8000 produces biodiesel fully automatically, only the dry-wash media replacement is performed manually.
