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
