Glycerol Definition• A syrupy, sweet, colorless or yellowish liquid,

obtained from fats and oils as a byproduct of saponification and used as a solvent, an antifreeze, a plasticizer, and a sweetener and in the manufacture of dynamite, cosmetics, liquid soaps, inks, and lubricants.

• Glycerol residues are obtained from production of palm oil kernel through glycerol refining.

OBJECTIVES• To recover pure glycerol from crude glycerol

residues

• To implement the process involved in glycerol recovery using methods of industrial networking and SCADA system

System Overview

Initial Process Acidification Separation Process

NeutralizationFiltering

Initial Process• Raw material (crude glycerol) is filled

into tank 1.

• Discrete Input– Liquid level switch

• Output– Inlet valve– Outlet valve

• PLC Involved (all input/output)– CQM1-H

Acidification Process• Mixing of sulfuric acid (using dosing

pump)• pH sensor detects the desired acidic

level (pH 4 – 5)

• Analogue Input: pH sensor• Discrete Input: liquid level switch

• Output: dosing pump, agitator motor, oil pump 2

• Analogue input connected to DeviceNet• Discrete input connected to CS1G-H unit• All output connected to CS1G-H unit

Separation Process• Solvent will be extracted by mixing

compound with diethyl ether• Compound will be separated into two

layers (fatty acid, glycerol)

• Analogue Input: Liquid density sensor• Discrete Input: Liquid level switches

• Outputs: agitator motor, motor pump 2, glycerol outlet valve, fatty acid outlet valve

• Analogue input connected to DeviceNet• Discrete input connected to CS1G-H unit• All input/output connected to CS1G-H unit

Neutralization Process• Mixing of sodium hydroxide (using

dosing pump) and heating at 90 ° Celsius to neutralize the solvent.

• Analogue inputs: temperature sensor, pH sensor

• Discrete inputs: Liquid level switches

• Analogue inputs connected to DeviceNet

• Discrete input/output connected to CQM1-H unit

Filterization Process• Glycerol filtered using lubricant

filter to remove solid particles.• End product achieved

• Discrete inputs: Liquid level switches

• Discrete outputs: outlet valve, inlet valve
