2.6 Manufacturing Process, Flow Diagram and Material Balance
The process of making ink involves making three different pigments. First, base for the required pigment is selected and the same is dissolved either in acidic or alkali media as per the process which is then diluted with ice cubes to achieve the desired temperature of the mass. In another reactor, a suitable coupler is selected and the same is again dissolved in suitable alkali or acidic media. Once, clear solution of both the above is achieved, they are allowed to react with each other in third reactor at certain predefined temperature, pH value and volume. The same is then subjected to salt and surface treatment to achieve the desired result.
Thus obtained slurry of organic pigment is then transferred to another reactor and allowed to be reacted with suitable varnish oil mix at certain temperature and pH in the presence of suitable additives.
These pre-dispersed pigments are then filtered through Nutche Filters and flushed into a sigma mixer. Here, the material is subjected to a high shear in the presence of extra quantity of varnish, alkyd and oil. The derived flush is diluted in the ink plant and converted into ink. Here, suitable additives and/or dryers are added before packing the ink.
2.6.1 Prinking Ink and Ink Concentrate
Varnish is prepared at high temperature by dissolving phenolic and hydrocarbon resins, in adequate proportion, in mineral oil at high temperature of 180ºC - 200ºC and after attaining required parameters, it is mixed in premix reactor with suitable pigment and with some mineral oil. Here it is subjected to high speed stirring for adequate mixing, and after passing through in-process quality assurance, the same mass is allowed to pass through grinding equipment like a bead mill and/or a triple roll mill with the parameters set as per the desired result. This mass is then accumulated to another reactor wherein further chemicals like additives, dryers and waxes are added to bring about an acceptable quality of ink. This mass is then filtered through an adequate filtration system and packed for dispatch.
2.6.2 Pigment Yellow 12
Dichlorobenzidine on reaction with sodium nitrite in presence of HCl at about 0ºC – 10ºC in ice/ water yields dichlorobenzidine diazonium salt. A surfactant is normally (though not always) used for controlling the particle size during the coupling reaction.
Rosination
Rosination is done by adding alkaline solution of rosin3 in the pigment slurry before / after filtration. During rosination, pigment particles get coated with rosin. Rosination is carried out where it is required and also depends on the application where pigment is used.
Filtration and Isolation of Press Cake
Filtration is carried out through filter press and pigment is isolated in the form of press cake, which contains water and pigment.
3 Rosin, also called colophony or Greek pitch (Pix græca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature, rosin is brittle, but it melts at stove-top temperatures. It chiefly consists of different resin acids, especially abietic acid.

Drying and Pulverization
Press Cake is dried and pulverized for making pigment powder.
2.6.3 AZO Pigments (BON Pigment): Rubine 57.1
Diazotization
Derivatives of amino benzene sulphonic acid react with sodium nitrite in presence of HCl at about 0 – 10ºC in ice / water yield diazonium salt.
Coupling
Diazonium Salt reacted with BON acid at about 5–25ºC in ice/ water yield pigment. Generally surfactant is used for controlling the particle size during coupling reaction. However it is not true for all the cases.
Rosination and Laking
Rosination is done by adding alkaline rosin solution in the pigment slurry before filtration. During rosination pigment particles get coated with rosin. Rosination is carried out where it is required and also depends on the application where the pigment is used.
Laking is done by reacting pigment with Calcium or Barium Salt.
2.6.4 Phthalocynine Pigment (ß– Blue)
Ball Milling
Crude Copper Phthalocynine is converted into ß form by grinding it through a ball mill. Different grinding times give different products, which are used for different applications.
Solvent Treatment and Purification
Grinded CPC is treated with solvent into the reactor. Solvent is removed by distillation. Resultant reaction mass is treated with suitable acidic media in water. The resultant slurry is filtered through filter press and Pigment was isolated in the form of Press Cakes.
D 2-1 refers the manufacturing process.

2.12 Rain Water Harvesting
Rainwater harvesting is a mechanism involved in collecting, storing and using rainwater when it is most needed. A rainwater harvesting system comprises of various stages - transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse or recharge.
There are five components in a rainwater harvesting system namely catchment, conveyance, filtration, storage and recharge.
2.12.1 Advantages of Rain Water Harvesting
There are various advantages of Rain Water recharging from which some of those are listed below:
1. Freshwater uptake is reduced as it allows use of rainwater in case of scarcity
2. Solution to water scarcity problems
3. Effective rise in ground water levels
4. Inexpensive and simple technology
5. It’s economical and energy saving as it prevents extraction of water from depleting ground water table
6. Provides high quality water, having low mineral content
7. Easy operation and maintenance
8. Reduces soil erosion
2.12.2 Design of Rain Water Harvesting
Quantity of Rain water collected depends upon:
1. Average rainfall intensity
2. Catchment area
3. Run-off coefficient
2.12.3 Design Calculations
Rainfall in Region: 922.7 mm/yr
Co-efficient and Factor Adopted:
1. Factor for terrace and roof top: 0.9 to 0.95
2. Factor for roads and paved areas: 0.9 to 1.00
3. Factor for garden, parks and green areas : 0.15 to 0.75

2.12.4 Components for Rain Water Harvesting Scheme
Catchment
The Catchment of a water harvesting system is the surface which directly receives rainfall. It can be a paved area like Terrace of a building or an unpaved area like lawn or open ground.
Manhole
Manholes are Brick Masonry Structure placed in between the Drainage line so that some percentage of water gets percolated directly through manhole. Percolation of rain water through manhole depends upon the permeability of the soil.
Each manhole, in this case, contributes around 10% of percolation depending on soil permeability.
Conduits/Pipeline
Conduits are pipelines or drains that carry Rain Water from the Catchment area to Rain Harvesting System.
De-silting Chamber
The rainwater first enters the de-silting chamber where the silt and floating oil gets separated from the flow. This oil is manually removed by scrapping from the top of the chamber and then overflows into the filtering chamber. The filtering chamber consists of pebbles, which further filters the rainwater before diverting it into the recharge well.
Filter Media in Rain Water Harvesting Pit
The filter is used to remove suspended pollutant from rainwater collected. A filter unit is a chamber filled with filtering media such as course sand, gravels, etc. to remove suspended material before it enters the recharge structure.
Recharge Structure
Rain water will be charged into ground water aquifers through recharge structure. It conducts water to a greater depth from where it joins the ground water.
2.12.5 Rainwater Harvesting Scheme
Rainwater harvesting scheme is given below.

2.17 Greenbelt Development
A green belt of approximately 28.42% of total plot area is proposed within the premises of OCL Balance area will be covered from open public land. OCL will encourage the community service projects for tree plantation. Greenbelt is designed to minimize the predicted level of the possible air pollutants. The scheme is designed4 based on guidelines provided by Central Pollution Control Board. Plantation along the boundary and roads shall be based on pollution absorption characteristics of the species and their vegetative cover. The green belt proposed shall fit the climate and soil of the region.
Tree species selected are absorbers of dust particles. Selection of the species is based on their pollution absorption capacity. The selected trees thus have large leaf surface area; deep root system and less litter fall. Faster growing trees with lighter canopy shall be planted alternatively with relatively slow growing trees with wider canopy.
Layout of the greenbelt has been shown in plot plan M-2.1.
