6. Conclusion


Being the only international industry located in premises of this region, it has provided a wide variety of departments from science to humanities. The industry mainly focuses on the safety as they phrase SHE comes first including Safety, Health, Environment parameters. They maintain the safety of the workers in and around the industry. With a hospital for routine medical checkup and industry mainly focus on the maximum manufacturing minimum waste agenda. The industry offers a product with a quality check by various chemical tests at the central laboratory which contains A class apparatus, chemicals, analyzers, various instruments conducting the test. I have been undergone the industrial training to enhance skills in the laboratory and also in preparation too.

I have done doing my industrial training at Hindustan Unilever limited in Khamgaon that began from 7 June 2018 to 22 June 2018. For being here I have been trained to analyze some ingredients in soap such as DFA also CSFA, RESIDUE, etc. I have also been introduced with many ways to determine Moisture, Acid value, Saponification value, etc. by using moisture analyzer or different laboratory methods.

Besides that, we manage to use the GLC machine and Tintometer properly. I have also participated in some activities and I had been run a project which is to be analyzed soon.

DFA (Distilled Fatty Acid) Plant.

Distilled Fatty Acid is a raw material required for manufacturing of the Soap. All Soap contain DFA as a raw material and production of this raw material is produced in DFA Plant by going through a different process.

In this DFA Plant, the main Product is the DFA (Distilled Fatty Acid) and produce some byproducts like Glycerin which is obtained after some processing on sweet water, Residue and Voilite obtained after the production of DFA.

This Plant is divided into four part

FSP=>FAD=>Sweet Water Treatment=> Sweet Water Evaporation

FSP (Fat Spitting Process)

This is the first part of the DFA Plant which includes the Spitting of the Fatty acid i.e. Blend Oil

1] First the Oil from Tank farm get to Basket filter where it gets filtered, then it goes to surge vessel to remove air, then the oil goes to preheater and from this it goes to spitting tower-1 and by same process water goes to spitting tower-2, here it gets mixed at 30 Hg/mm and high temp. of 2300-2400C and 2400-2450C in spitting tower 1 and 2 respectively.

Here at this Pressure and Temperature oil get spat and CSFA and Sweetwater are obtained. CSFA from spitting tower 2 and Sweetwater from Spitting tower 1. after then it goes to CSFA receiver and Sweetwater receiver.

FAD (Fatty Acid Distillation)

In this Part, the CSFA produces in the FSP is used as raw material and production of DFA is done using the following process.

1] In FAD, CSFA is the raw material, first, it gets filtered by Basket Filter.

2] Then it moves to SHE and gets heated then after some temperature rises its move to the dryer.

3] In the Dryer the moisture get dried, and move to the CSFA preheater and get heated and after that moves to precut.

4] In the Precut in temperature rise to 1850 C- 2000C and pressure 2-3 mmHg and here the volatile get separated by condensation in the condenser and get collected in the Volatile receiver and oil moves to Main Steel.

5] In the Main Steel the Temperature rise to 2300 C-2320C and pressure is 2-5 mmHg this make the residue to settle at the bottom and by condensing the Steam and collecting it DFA the Final product is obtained.

6] This Residue is store in Residue Receiver and the DFA is store to DFA Receiver tank, and then moves to the tank farm.

7] In the Tank farm DFA can Be Stored for 8 days by Blanketing the Nitrogen over the tank.

Sweet Water Treatment

  • In this Sweet Water Treatment Plant, the Sweetwater obtained as the raw material in the FSP Plant is treated in this treatment the oil is separated from the sweet water by adding some chemical i.e. EAU and after this treatment Glycerin is obtained by evaporation of water from this sweet water.

1] Sweetwater from the storage tank is fed to Sweet Water Tank and here the treatment takes place.

2] In the Sweet Water Tank EAU is added to separate oil and Water layer and takeout manual. This Tank contains Coil and air and caustic pipe to maintaining PH level up to 8.5-9.

3] After all this treatment which take 1.30 min approx. it moves to the evaporation plant.

SWE (Sweet Water Evaporation)

In this part of DFA Plant, the Crude Glycerin is obtained by evaporation of the treated sweet water from the Treatment plant.

Evaporation plant Consist of 3 Evaporation tank and 3 expansion vessel which is under pressure, barometer connected to expansion vessel 3.

1] After the Sweet Water Treatment it comes to Sweet Water Evaporation plant and then here it passed through the preheater and get some temperature.

2] Afterward that it moves to the expansion vessel 1 and the circulation between evaporator 1 and expansion vessel 1 is carried out.

3] Catch All is connected to an expansion vessel for production of High-Pressure Steam.

4] From the expansion Vessel 1 the Sweetwater moves to Expansion vessel 2 and from there in circulating to evaporator tank 2 and this evaporator is connected to Condensate drum 2.

5] Catch All is connected to Expansion vessel 2 From this expansion vessel it goes to expansion vessel 3 and circulates to evaporator 3 and this evaporator is connected to Condensate drum 3

6] Crude from the Expansion vessel three is collected and store and steam from the upper side goes to Catch all 3 and from there in barometer and get cooled and get a store in condensate tank.

• Analysis of Oil, Residue, Volatile and DFA in the DFA Plant.


1. To analyze the UnSap value of hard PDFA oil.

2. To analyze the Acid value, Colour, DOS, Iodine Value of all different.

3. To analyze the Glycerin Percentage in sweet water or in crude Glycerin.

4. To increase the proficiency and Control the Quality of DFA, and maintain the Standard.

Acid Value

Take a conical flask of normal temperature, take the Sodium sulfate anhydrous powder in filter paper with a sample (CSFA, DFA, Residue). Take 5 gram of sample (15-20 drops) in a conical flask. Then take a mixture of phenolphthalein and NaOH in minor quantity in 99% of pure Ethanol to the neutral solution. Then give heat by using heating mental at 80-100 C also add small stone of sand to avoid jumping. After heating adds 2-3 drops of phenolphthalein then titrate with 0.1 N NaOH solution and measure the burette reading.

7] GLC (Gas Liquid Chromatography)

Calculate the moisture of soap. Take this sample crushed it. Add of 3 ml of Boron trifluoride Methanol complex solution (BFT). Heat it on a water bath at 85 0C for only 4-5 min. Add 6 ml Heptane (used to stop CNO init heat), just warm it. These will form methyl ester then add brine solution which separates the soap and oil.

This method will be used to know the quantity of Linolic acid, Steric acid, Palmitic acid, Lauric acid, Capric acid present in the Soap.


The required raw material stored in a stock tank such as PEG, Caustic, CNFA.The pre-melter contain the material PG, PEG, Steric acid, Lauric acid and Hd-Pko.the capacity of pre-melter is about 60 tonnes and its temperature is 40-45 C. Then it blends with the pump.PEG and PG act as solvent and Hd-PKO is oil. The main component is oil and caustic. the caustic range might be 0.50-1.60.

It is passed through scrap melter to the Primary vessel which is consist of Rosin, BHT, caustic, salt, Gly and water. Rosin act as a binding agent, BHT is anti-fungal, salt is used for destroyed lumps present in it. its temperature is 500C and takes 50 min. the pre-primary vessel contains EHDP, EDTA, sorbitol, and recyclable soap. EDTA and EHDP are required 85 C and 5 min action but pours in the vessel in an alternative manner. Sorbitol and SLS required 82 C – 15min .if caustic is required to add in secondary vessel. After the primary vessel is filtered and goes to the secondary vessel.

In the secondary vessel, color is added such as yellow(quinoline), perfumes and IPA. The temperature of the secondary vessel is 80 Degree Centigrade. IPA and water is the penaturate spirit which decides the transparency of soap. There is a CCP (critical control process) in which impurities, color, and any foreign matter are removed. Then the bar sample takes and goes to the lab. After approval, the batch is dispatched to the bar schematic cooler and produce 90 bar at a time. This bar undergoes to the stamping and packaging…


To avoid the Carryover of Sweet Water from the 3rd Expansion vessel tank to ICW Cooling Tower.


1] To Stop the Carryover of Sweetwater in ICW cooling tower.


1] Add Antifoaming Agent in the Sweetwater treatment tank to avoid the tank level error occur when manually checked.

2] Bend the Pipe in the Expansion vessel -3, as this is near the vacuum suction this also one of the main reason for carryover water.

3] Maintain the level of expansion vessel tank.

a) Add an Auto Control Valve to the inlet of sweet water from evaporator 2 and b) Add a Level indicator to expansion vessel-3 and give the automation to stop the feed inlet from the Sweetwater tank.

c) Make the Seal Pot big in the width and add Semi-permeable membrane to trap Glycerin and this passes water from it.

d) Add Glycerin Adsorption material in seal pot i.e. Magnesium Silicate, Silicate Crystal.


Based on experience for 16 days in Hindustan Unilever, this suggestion can be taken into consideration to upgrading future practical training in this place:

1. The duration of training may be longer as it will be more beneficial, giving more exposure to the trainers to allow them to understand the flow of the project. The shorter duration was not viable for practitioners to let the trainee handle a project more comprehensively. The longer duration would give the students more time to explore and experience on the project.

2. Should add a Level indicator i.e. Transparent Glass Pipe, having the scale at back side to show the level, to every Tank in DFA Plant this helps to know the Level by just seeing it and also show two different layer of oil and water, this will also save some loss occurs while operating it manually without knowing the level and for keeping it hot give it a steam line joint connection.


Hindustan Unilever Limited (HUL) is the Best Company in the world and also the best place for a Chemical Engineer to get exposure to the chemical industry. From this industrial training, the student can improve their laboratory skills, problem-solving skill by giving them such kind of project and task and also can increase their knowledge.

Besides, I also can train myself to be good in attitude while doing my work. In addition, my problem-solving skills and research skills can also be improved as when I was doing a project on avoiding the Carryover of sweet water from 3rd Expansion Vessel to enter in Cooling Tower. This Knowledge is important for our Chemical Engineering student who wants to work in industries in the future.
