摘要： Suggested is a process for obtaining fatty acid C 1 -C 4 alkyl esters from unrefined fats and oils, which is characterised in that:
(a) unrefined fats or oils having an acid value of from 1 to 20 are treated with hot steam in a counter-current column to provide a first fraction of free fatty acids and low boiling impurities at the top and a second fraction of de-acidified and de-watered fats or oils at the bottom of the column;
(b) said first fraction is subjected to acidic or enzymatic esterification with a lower C 1 -C 4 alcohols in order to provide a third fraction of fatty acid C 1 -C 4 alkyl esters;
(c) said second and said third fraction are combined and subjected to a low pressure transesterification in order to provide an intermediate fraction of fatty acid C 1 -C 4 alkyl esters, C 1 -C 4 alcohols and glycerol; and
(d) said intermediate is subjected to a separation process in order to remove C 1 -C 4 alcohols and the glycerol in order to provide a second fraction of C 1 -C 4 alkyl esters.摘要翻译： 建议是用于获得由未精制的脂肪和油脂肪酸的C1-C4烷基酯的方法，所有这些是DASS：（a）具有1至20的酸值未精制的脂肪或油与在热蒸汽处理 逆流塔中提供的游离脂肪酸和低沸点杂质在顶部和的第二部分的第一部分脱酸进行脱水在塔的底部的脂肪或油; （b）所述第一级分进行酸性或酶促酯化与低级C 1 -C 4醇，以提供的脂肪酸C 1个-C 4烷基酯的第三级分; （c）所述第二和第三所述馏分合并，并为了在的脂肪酸C 1 -C 4烷基酯的中间部分，以提供经受低压酯交换，C 1 -C 4醇和甘油; 和（d）所述中间体进行分离处理，以除去以提供C1-C4烷基酯的第二部分C1-C4醇和甘油。

摘要： Suggested is a process for obtaining fatty acids with reduced content of by-products, characterised in that
(a) unrefined fats or oils are subjected to steam stripping in a counter-current column to produce
(i) a bottom fraction of de-acidified fats or oils,
(ii) a first distillate consisting mainly of fatty acids and glycerides, and
(iii) a second distillate comprising fatty acids and essentially all unwanted ketones, aldehydes and phenols; and
(b) said bottom fraction (i) containing the de-acidified fats or oils and said first distillate (ii) containing fatty acids and glycerides are combined.摘要翻译： 建议用于获得具有降低的副产物含量的脂肪酸的方法，其特征在于（a）将未精制的脂肪或油在逆流柱中进行蒸汽汽提以产生（i）脱酸脂肪的底部馏分 或油，（ii）主要由脂肪酸和甘油酯组成的第一馏出物，和（iii）包含脂肪酸和基本上所有不需要的酮，醛和酚的第二馏出物; 和（b）含有脱酸脂肪或油的所述底部馏分（i）和含有脂肪酸和甘油酯的所述第一馏出物（ii）组合。
