THE EFFECT OF GLYCEROL CONCENTRATION ON PRODUCT DENSITY IN STEAM STRIPPING EQUIPMENT WITH RASCHING RING PACKING TYPE

Abstract

Stripper is a separation process between a mixture of two liquid phase substances by using a gas phase substance as a separator. In this case, glycerol and H₂O are used as a mixture and steam is used as a separating agent with the aim of removing the H₂O content contained in the glycerol. In the separation process, variable variations are used in the form of concentrations of glycerol and H₂O, respectively, concentrations of 70 %, 80 %, and 90 % against a predetermined temperature and pressure of 140^oC and 45 Psi, with the aim of knowing what the glycerol and H2O concentrations are in the separation process. can work optimally. The process that occurs is a separation process based on boiling point, where water which has a lower boiling point of 100^oC will be separated from glycerol with the help of steam with a temperature of 140^oC. At a variable concentration of 70 % glycerol feed with a predetermined temperature and pressure, the data obtained is that the product still contains 4 % water in the glycerol product, the results of the process still do not meet the desired product conditions, namely 99.5 %. On the other hand, with a variable concentration of 90 % glycerol, this product only contains 1 % H₂O, it can be concluded that the concentration of feed glycerol on H₂O is very influential in the process of eliminating H₂O levels in glycerol, because the higher the concentration of glycerol on H₂O the work of steam in binding H₂O is lighter so that steam can strip the H₂O content in the feed more maximally.
