Q: CPC Blue Manufacturing

Stage 1Add Ortho Chloro Aniline in H.S. Acid in chlorinated Cresol in fine reaction.Then add urea, Phthalic Anhydride, Cuprous Chloride and Ammonium Poly Sulphide to melt.Raise the temp up to $185 \text{ deg C}$.During the process of melt, whatever gases are evolved, such as sulphur dioxide gas is passed out of the reactor and absorbed by $10\%$ caustic lye in storage tank/reactor and then after acid wash/blow. From the water scrubber we can also absorb ammonium carbamate as a byproduct.After maintaining sufficient time during the batch in R.S. reactor for maximum condensation.That will recover $\pm 90\%$ of the solvent. And transfer the remaining crude in HDPE/L vessel containing water.Stage 2Prepare water soluble crude material into dumping vessel with spent sulphuric acid (recover $60\%$ from flake fines and acid sludge).Maintain temperature up to $95 \text{ deg C}$ in $15,000 \text{ L}$ glass lined reactor for $3 \text{ hrs}$.Then filter in filter press, wash it, neutralize it, dry it, pulverize it and packed the crude material in a $50 \text{ kgs}$ bag.Stage 3 (Pigmentation)After blowing the water soluble crude material which will be neutralized that contains $0.8\%$ of sulphuric acid, we will treat it with a mild solution of $\text{NaOH}$ to become neutral. Then we will exchange it with $\text{NaCl}$ in $60 \text{ deg C}$, wash.

Q: Alpha Blue Manufacturing

Stage 1 (Wet process)Use Sulphuric acid ($\text{H}_2 \text{SO}_4$) in a reaction vessel. Then slowly charge Copper Powder at $50 \text{ deg C}$.Maintaining temperature just below $80 \text{ deg C}$. So as to dissolve it $85\%$ completely.The mass is stirred further for $6 \text{ hrs}$ at $80 \text{ deg C}$ and then cooled to room temp. by chilled water circulation in the jacket.Recycled water is then introduced as a thin slurry into the vessel slowly, taking care that the temperature does not rise above $50 \text{ deg C}$.The $\text{CPC}$ separator size in the required form and is filtered off.After filtration process, whatever reactor foam generated that contains approximately $10 \text{ to } 12\%$ of the crude, the same quantity will be used for the next reaction of Alpha Blue.Stage 2 (Pigmentation Process)Wet product is charged to reactor, treated and washed with water and diluted with fresh water.The resultant slurry is treated with $\text{H}_2 \text{SO}_4$ for $\text{pH}$ $0.5 \text{ to } 1.0$ using ammonia solution and caustic lye and heated with condenser at $90 \text{ deg C}$ for $3 \text{ hrs}$.The dilute slurry is filtered and the cake is washed with required amount of fresh water.Then the cake is dried at $60 \text{ deg C}$ for $24 \text{ hrs}$.The aqueous filtrate $\text{GTS}$ goes to $\text{ETP}$. Then after it is discharged it is $650 \text{ to } 670 \text{ Kgs}$.

Q: Beta Blue Manufacturing

Stage 1 (Milling)Crude $\text{CPC}$ ($\text{PB}$ $15.0$) is put into ball mill of capacity $15,000 \text{ kgs}$, add few solvents for $24 \text{ hrs}$.After $24 \text{ hrs}$ discharge the milled slurry for stage $2$ (pigmentation).Stage 2 (Pigmentation)Charge crude milled blue into all vessels, dissolve caustic, urea, surfactants and dispersing agents. Stir up for $2 \text{ to } 3 \text{ hours}$.Then recover the pigment, filter the pigmented mass through filter press, wash with water till neutral $\text{pH}$. Dry the pigment cake in open flask dryer at the rate of $75 \text{ kgs}$.

CPC Blue Manufacturing

Stage 1

Add Ortho Chloro Aniline in H.S. Acid in chlorinated Cresol in fine reaction.
Then add urea, Phthalic Anhydride, Cuprous Chloride and Ammonium Poly Sulphide to melt.
Raise the temp up to $185 \text{ deg C}$.
During the process of melt, whatever gases are evolved, such as sulphur dioxide gas is passed out of the reactor and absorbed by $10\%$ caustic lye in storage tank/reactor and then after acid wash/blow. From the water scrubber we can also absorb ammonium carbamate as a byproduct.
After maintaining sufficient time during the batch in R.S. reactor for maximum condensation.
That will recover $\pm 90\%$ of the solvent. And transfer the remaining crude in HDPE/L vessel containing water.

Stage 2

Prepare water soluble crude material into dumping vessel with spent sulphuric acid (recover $60\%$ from flake fines and acid sludge).
Maintain temperature up to $95 \text{ deg C}$ in $15,000 \text{ L}$ glass lined reactor for $3 \text{ hrs}$.
Then filter in filter press, wash it, neutralize it, dry it, pulverize it and packed the crude material in a $50 \text{ kgs}$ bag.

Stage 3 (Pigmentation)

After blowing the water soluble crude material which will be neutralized that contains $0.8\%$ of sulphuric acid, we will treat it with a mild solution of $\text{NaOH}$ to become neutral. Then we will exchange it with $\text{NaCl}$ in $60 \text{ deg C}$, wash.

Alpha Blue Manufacturing

Stage 1 (Wet process)

Use Sulphuric acid ($\text{H}_2 \text{SO}_4$) in a reaction vessel. Then slowly charge Copper Powder at $50 \text{ deg C}$.
Maintaining temperature just below $80 \text{ deg C}$. So as to dissolve it $85\%$ completely.
The mass is stirred further for $6 \text{ hrs}$ at $80 \text{ deg C}$ and then cooled to room temp. by chilled water circulation in the jacket.
Recycled water is then introduced as a thin slurry into the vessel slowly, taking care that the temperature does not rise above $50 \text{ deg C}$.
The $\text{CPC}$ separator size in the required form and is filtered off.
After filtration process, whatever reactor foam generated that contains approximately $10 \text{ to } 12\%$ of the crude, the same quantity will be used for the next reaction of Alpha Blue.

Stage 2 (Pigmentation Process)

Wet product is charged to reactor, treated and washed with water and diluted with fresh water.
The resultant slurry is treated with $\text{H}_2 \text{SO}_4$ for $\text{pH}$ $0.5 \text{ to } 1.0$ using ammonia solution and caustic lye and heated with condenser at $90 \text{ deg C}$ for $3 \text{ hrs}$.
The dilute slurry is filtered and the cake is washed with required amount of fresh water.
Then the cake is dried at $60 \text{ deg C}$ for $24 \text{ hrs}$.
The aqueous filtrate $\text{GTS}$ goes to $\text{ETP}$. Then after it is discharged it is $650 \text{ to } 670 \text{ Kgs}$.

Crude $\text{CPC}$ ($\text{PB}$ $15.0$) is put into ball mill of capacity $15,000 \text{ kgs}$, add few solvents for $24 \text{ hrs}$.
After $24 \text{ hrs}$ discharge the milled slurry for stage $2$ (pigmentation).

Stage 2 (Pigmentation)

Charge crude milled blue into all vessels, dissolve caustic, urea, surfactants and dispersing agents. Stir up for $2 \text{ to } 3 \text{ hours}$.
Then recover the pigment, filter the pigmented mass through filter press, wash with water till neutral $\text{pH}$. Dry the pigment cake in open flask dryer at the rate of $75 \text{ kgs}$.
