摘要： A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterfication process, may proceed by the addition of a mineral or an organic acid.
摘要翻译：用于将游离脂肪酸转化为甘油酯的系统和方法以及随后将甘油酯转化为甘油和生物柴油包括甘油酯流与醇的酯交换反应。将脂肪酸烷基酯与甘油分离以产生含有富含脂肪酸烷基酯（浓缩）料流的第一液相和含富甘油（浓缩）料流的第二液相。然后将富含脂肪酸烷基酯的物流进行蒸馏，优选反应蒸馏，其中物流分离和化学反应。然后纯化富含脂肪酸的富含烷基酯的料流以产生纯化的生物柴油产物和富含甘油酯的残余物流。在碱催化的酯交换过程中形成的碱性流的中和可以通过加入矿物或有机酸来进行。

The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. Biodiesel may be further recovered from the glyceride rich residue stream, by further separation of and/or processing of glycerides/free fatty acids contained therein. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterification process, may proceed by the addition of a mineral or an organic acid.
