Glycerol Recovery Rate

1.Glycerol Recovery Rate

The recovery rate of glycerol is calculated according to the following formula:

Glycerol recovery rate=Output of this month ÷ Input of theoretical glycerol in oil and fat of this month + The amount of glycerol left unfinished of last month - The amount of glycerol remaining unfinished of this month)

Theoretical glycerol input= Oil content(t) * (Saponification value - acid value)×0.0547

The amount of glycerol left unfinished last month(For example, the recovery of glycerol from sweet water hydrolyzed by oil)= Glycerol in Sweet Water [Sweet Water Quantity * Concentration (%)]+ Glycerol content(clear water quantity * concentration (%)) in 1#Clean water (Lime milk treated water) 十 Glycerol content in 2# clear water (sodium carbonate treated water) [secondary clear water quantity * concentration (%)] + Crude glycerol [volume * density * concentration (%)] + Glycerol content of various semi-finished products (glycerol in various containers in distillation condensation receivers, decolorization tanks and unfilled tanks)

The amount of glycerol in clear water [the amount of 1#clear water * concentration (%)] + the amount of glycerol in 2#clear water [the amount of 2#clear water * concentration (%)] + the amount of crude glycerol [the volume X density X concentration (%)] + the amount of semi-finished glycerol (the glycerol in different containers in distillation condensation receivers, decoloration tanks and unfilled storage tanks)
