Annexure I

Process Description

M/s APIL presently manufactures Enamels, Water based Paints, Industrial

Paints, Stiff Paints and Synthetic Resins at its Ankleshwar division. The same products

are proposed to be manufactured after the debottlenecking exercise. The requirement of

raw materials is summarized in Table 2.1 whereas the existing and proposed increase in

production is presented in Table 2.2.

2.1 Manufacturing of paints

The paint manufacturing process involves the following steps:

1. Wetting the pigment with sufficient quantity of appropriate resin, thereby

breaking large agglomeration to make a mill base which has a correct

consistency for grinding. This process called pre-dispersion is achieved in

Cowl's dissolver or similar pre-disperser

2. The next step involves further breaking up of the pigment aggregates and

their suspension in resins. Different machines like attritor, sand mill, bead mill

and jar mill are used for dispersion. Type of paint and nature of pigment

dictate the selection of a mill or a combination of mills. Ball mills can also be

used as dispersion equipment. In such a case pre-dispersion is not necessary.

All the ingredients are directly charged into the mill and the mill is run for the

specified time ' to achieve requisite characteristics

3. Adjusting the shade consistency and other desired properties of the product is

the next step. The milled pigments are transferred to mixers where additives

like drying agents are added. The remaining quantity of materials like resins

and thinners are also added in mixers. The consistency, viscosity, colour and

drying time are adjusted in the mixer

4. The final step is packing of the paints in containers. On approval of the paint

against specifications, the paint is strained and packed in required pack sizes.

The pack size and type of paint decide the appropriate packing machine. The

process of primer production in ball mills and enamel production in sand mills

are depicted in Fig-2.1.1 and Fig-2.1.2 respectively. The process schematic

of water based paint is shown in Fig-2.1.3

Fig. 2.1.3: Flow Diagram for Water Based Paint Unit

14

2.2 Manufacturing of distemper

Distempers are wall finishes, sold in the form of stiff pastes of uniform and

smooth consistency. Processing of distempers is carried out in a single stage in pug

mixers that have a pair of helical mixers revolving in opposite direction. The powdered

raw materials together with binder solution and other additives are charged in pug mill.

The dispersion is achieved by the sheer force and pugging action generated in the pug

mill. Shade and other adjustments are carried out in the mill itself and the material is

packed on special packing machines suitable for stiff mass. The process of distemper

manufacture is depicted in Fig- 2.2.1.

15

Fig. 2.2.1 : Flow Chart for Synthetic Distempering Unit

16

2.3 Manufacturing of resins

a. Alkyd resins

Synthetic resins of alkyd type are manufactured by chemical reactions of

polyol, oil and polyacid in presence of catalyst and certain additives in thermic fluid

heated reaction vessel. The reaction is monitored by checking temperature, viscosity,

acid value and percent solids. Time required for reaction varies from 18 hrs to 48 hrs.

This is followed by thinning in blender with solvents to the desired percentage solids and

filtration take place in a plate type pressure filter and after filtration the product is

pumped into storage tanks. The above mentioned process is shown in Fig-2.3.1.

b. Acrylic solution resins:

Manufacturing of Acrylic solution resins involves following steps;

1. Monomers are mixed with the solvents like methyl ethyl ketone (MEK) and

toluene

2. Part of the above mixture is taken to the reactor

3. Remaining part is taken to premix tank and the catalyst is added under

continuous stirring

4. The reactor is heated to 75-80OC in atmosphere of nitrogen under continuous

stirring

5. The catalyst is mixed with the solvents and added to the reactor at 70-

80OC for 30-60 min.

6. Temperature increase is recorded and desired temperature is maintained by

cooling

7. The contents of premix tank are added slowly and continuously to the reactor

8. On completion of addition of premix solution, the catalyst is added to the

reactor. The reactor is maintained at 80OC for 4 hours to ensure complete

polymerisation

9. The product is cooled and solvents are added to achieve desired solid contents

and viscosity. The products are filtered and stored.

C. Emulsion resins:

Following steps are involved in manufacturing process

1. Water and surfactants are taken to the reactor and heated to 55-60OC. On

achieving desired temperature, initiator catalyst is added. The temperature of

the contents is controlled to 75-80°C

2. Monomers are added continuously to the reactor under continuous stirring

17

3. On completion of monomer addition, catalyst is added to the reactor. The

reactor is maintained at around 80OC for two hours to ensure complete

polymerisation

4. On cooling, the emulsion is neutralised and other additives like defoamer and

preservatives are added

5. The emulsion is strained and stored. The process flow sheet is shown in Fig-

2.3.2.

18

2.4 Manufacture of Amino Resins

Butanol is charged in the separator vessel by using vacuum. While stirring the

powdered raw material, catalyst solutions are added manually. This is heated to 90°C

while observing the desired parameters and then it is cooled to 35-40°C. The desired

constants are checked.

Powdered raw materials from bags and acid are added by opening the reactor

manholes. The required parameters are checked and the heating is started. The

temperature is maintained. Water of reaction is collected. Recovered alcohol of previous

batch is added and the desired parameters are checked. After heating, the water of

reaction is separated. Again the desired parameters are checked. Alcohol is recovered

under slight vacuum. Then the batch is cooled and filtered through percoat filter and

collected in rust free barrels.

Pollution Load Assessment after the proposed expansion

Point Source Emissions

The main source of point emissions are from the stacks attached to the various

utilities. The Liquefied Petroleum Gas (LPG) consumption in the proposed

production enhancement will increase where as HSD consumption will decrease,

which in-turn will decrease SO2 emission load. The fuel requirement for the

existing plant and after enhancement is given in Table below.

1 Liquefied Petroleum Gas 1315 3500 ---

2 HSD 1709 1452 0.25

Note : Utilities which are operating using HSD as fuel will be switch to LPG. Hence

there will be decrease in HSD consumption.

Sulphur Dioxide Emissions

• Sulphur Dioxide Load due to existing production

HSD consumption rate : 1709 Kg/day

Sulphur content in HSD : 0.25%

Sulphur dioxide emission factor : (0.25/100) x 64/32 = 0.005

SO2 emission rate : (1709 Kg/day) x 0.005

= 8.55 Kg/day

• Sulphur Dioxide Load after production enhancement

HSD consumption rate : 1452 Kg/day

Sulphur content in HSD : 0.25%

Sulphur dioxide emission factor : (0.25/100) x 64/32 = 0.005

SO2 emission rate : (1452 Kg/day) x 0.005

= 7.26 Kg/day

Due to the decrease in HSD consumption SO2 emission are likely to decrease

from 8.55 Kg/day to 7.26 Kg/day after production enhancement.

Water Environment

The total wastewater generated from the existing process is about 111 m3/day.

After the proposed production enhancement the wastewater generation will

remain same and will be treated in the existing Effluent treatment plant of

200m3/day capacity. Hence there will be negligible increase in pollution load due

to proposed production enhancement. The comparative water balance statement

for the existing capacity of production and for the proposed production

enhancement is presented in table below.

The pollution load due to the generated wastewater is presented in Table below.

The treated water wastewater is recycled /reused completely within the plant

premises.
