System for creating a biofuel

A system for creating a biodiesel fuel using main biodiesel production equipment comprising:

• (a) a biofuel reactor comprising:
• at least one chamber;
• at least two atomizers in the at least one chamber comprising:
• a first atomizer in the at least one chamber comprising at least one light phase biofuel feedstock nozzle for receiving and atomizing a light phase biofuel feedstock, and
• a second atomizer in the at least one chamber comprising at least one short chain alcohol with catalyst nozzle for receiving and atomizing a short chain alcohol with catalyst, wherein a stream of reacted microparticles is quickly formed when the atomized light phase biofuel feedstock contacts the atomized short chain alcohol with catalyst;
• (b) a polyol separator in fluid communication with the biofuel reactor, wherein the polyol separator is adapted to receive and separate the stream of reacted microparticles into a crude polyol stream and a crude biodiesel stream;
• (c) a conduit comprising:
• a wash water inlet for introducing fresh wash water to the crude biodiesel stream, and flowing the crude biodiesel stream mixed with fresh wash water to a wash water separator, wherein the wash water separator is adapted to separate a first portion of wash water from the crude biodiesel stream to form a washed crude biodiesel with a second portion of washing water;
• (d) a heat exchanger for heating the washed crude biodiesel with the second portion of washing water to form dried biodiesel and wash water vapor;
• (e) a cooler for receiving the dried biodiesel and forming a cooled biodiesel;
• (f) a filter for receiving the cooled biodiesel and removing particles from the cooled biodiesel to form a final biodiesel;
• and
• (g) a secondary process treatment equipment comprising:
• a neutralization vessel adapted to receive the crude polyol stream, the first portion of the wash water, and a recycle acid stream, wherein the neutralization vessel is adapted to neutralize the crude polyol stream, wash water, and recycle acid streams to a pH of about 3.5 to 4.0 forming a neutralized mixture;
• a phase separator for receiving the neutralized mixture and forming an oil stream and a second crude polyol stream;
• an esterification conduit for dosing a short chain alcohol into the oil stream and for dosing an esterification acid into the oil stream;
• an acid esterification reactor for esterifying the oil stream to form a mixture of a fatty acid ester and an acid/alcohol mixture;
• an acid esterification phase separator for receiving the mixture of the fatty acid ester and the acid/alcohol mixture and forming the recycle acid stream and a crude fatty acid ester stream, wherein the crude fatty acid ester stream flows back to the biofuel reactor, wherein the recycle acid stream flows back to the neutralization vessel;
• a polyol dryer for forming at least two components from the second crude polyol stream, including a water alcohol stream adapted to receive wash water vapor, and a final polyol product;
• and
• an alcohol rectification unit for separating water and alcohol from the water alcohol stream.
