Biodiesel methyl ester distillation section

Biodiesel methyl ester distillation section: pretreatment section, esterification reaction section, methyl ester distillation section, methanol recovery section, high vacuum system.

Mainly used as fuel for mechanical equipment, with stable performance, thorough combustion, and strong power. No odor.

Generally, crude methyl ester containing glycerol soap is generated by the reaction between raw oil and methanol. After washing with water, it enters a disc centrifuge to quickly separate the mixture of crude methyl ester and glycerol soap water.

The crude methyl ester after centrifugation,Then it enters the falling film dehydration tower from its original location and removes the residual water. The resulting product is distilled in two parts from the distillation tower.

The biodiesel methyl ester distillation section is equipped with a circulating oil cooling system at the top of the tower, and the upper part of the tower is taken outThe distilled cooling material is the finished product of biodiesel. The distilled cooling material is taken out from the top of the tower as odorous substance (light component oil), and the waste heat is comprehensively recovered and utilized, reducing the thermal energy consumption in production costs by more than 20%. The distillation system is equipped with vacuum cold well protection, which not only increases the yield of odorous substance (light component oil), but also ensures the smooth operation of the vacuum unit. The biodiesel yield can be guaranteed to reach over 92%, with an acid value ≤ 0.5mgKOH/G and no odor.
