By analyzing the continuously widening gap between existing and operational biodiesel capacities we have concluded that there are two major concerns that must be considered for improving the state of biodiesel processing business:Lack of profits especially because of too much reliance on subsidies.A production unit must produce profit without any subsidy!There are fundamental issues of unit operations in biodiesel production that have not been addressed correctly, because subsidies masked problems! To elucidate the root causes we have performed a series of colloid chemical and unit operational research experiments.Our recommendations to cut losses in production and to improve profitability range from seed and refuse oil treatment operations to modification of the phase behavior in esterification and trans-esterification.To increase profitability of an existing unit it is adamant to control all channels for loss of feedstock resource and to turn the production systems more efficient.By the use of a suitable apolar solvent at a suitable rate in a suitable proprietary process technique adverse impacts on profitability can be adequately addressed.In addition to cut in losses, but in symbiotic combination of operational duties the significantly reduced specific consumption of energy and auxiliaries contribute to significant improvement in profitability of the unit, in addition to higher throughput at not excessive investment levels.Special aspects of truly continuous operational technology for green field investment and improved, apparently continuous technology variants for retrofitting existing plants will be presented.
