1. INTRODUCTION AND JUSTIFICATION OF THE PROJECT

1.1. Identification of Project

M/s Sarara Chemicals is willing to install a plant for production of Synthetic Resin with a

capacity of 5400 MTPA, in the land of 1335.45m2 at R.S. Plot No 200; L.R. Plot No 481;

Mouza – Bhajanpur; Village – Kuakandar; Dist – Darjeeling, West Bengal.

Because of high market demand, the project proponent is willing to produce two types of

synthetic resin i.e. Urea-Formaldehyde Resin (U-F Resin) and Phenol-Formaldehyde Resin

(P-F Resin). The production capacity of the two types of resins will be 3780 MTPA and 1620

MTPA respectively.

The proposed project is satisfying the General Condition of the EIA Notification as the India

– Nepal International boundary is in 4 km and the West Bengal-Bihar State Boundary is in

1.4 km from the project site. So the proposed project will be considered as Category A.

Thus the unit is categorized under Category „A‟ of Schedule no. 5(f) for “Synthetic organic

chemicals industry” as per EIA notification and its latest amendment

1.2. Identification of Project Proponent

M/s Sarara Chemicals is a proprietorship concern having its office at Village Kuakandar;

Mouza & P.O. Bhajanpur; P.S. Khoribari; Dist. Darjeeling.

The proprietor of the firm is Smt. Rekha Agarwal, wife of Sri Ashok Kumar Agarwal, is

resident of Gitanjali Complex, Behind Corporation Bank, 2nd Mile, Sevoke Road, Siliguri,

Dist. Jalpaiguri – 734001, The proprietor of the firm is from highly reputed business family

of Siliguri having wide business experience.

1.3. Need of Project and its Importance

The proposed synthetic resin plant will be set up with an installed capacity to manufacture

around 5400 MT per annum. The proportion of U-F resin and P-F Resin production is

proposed to be at 70: 30 ratios. U F Resin and PF Resin are used in plywood manufacturing

for pasting of veneer sheets. There are large number of plywood manufacturing units in North

Bengal and adjoining Bihar. There is a good demand for U-F and P-F Resin in neighboring

country - Nepal.

The unit proposes to export about 70% of its production to Nepal. Where number of plywood

units are situated who are using U-F and P-F Resin.

Considering good export as well as domestic market, marketability of the product will not be

a problem at all.

Pre-Feasibility Report for M/s Sarara Chemicals Page 5

1.4. Demand Supply Gap:

Demand of synthetic resins in the country is increasing day by day. These synthetic resins are

used in adhesives, finishes, particle board, MDF, and moulded objects.etc.

Urea Formaldehyde and related amino resins are considered a class of thermosetting resins of

which urea-formaldehyde resins make up 80% produced globally. Examples of amino resins

use include in automobile tires to improve the bonding of rubber to tire cord, in paper for

improving tear strength, in moulding electrical devices, jar caps, etc.

Phenol Formaldehyde Resins (PF) or Phenolic Resins are synthetic polymers obtained by the

reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite,

PFs were the first commercial synthetic resins (plastics). They have been widely used for the

production of molded products including billiard balls, laboratory countertops, and as

coatings and adhesives. They were at one time the primary material used for the production

of circuit boards but have been largely replaced with epoxy resins and fibreglass cloth, as

with fire-resistant FR-4 circuit board materials

Competition in the Indian market swells in recent years. This had many companies opting out

of low-margin segments, as competition resulted in lower prices. A gap between demand and

supply is created. Such remarkable price hikes take place when there is removal of some of

the key competitors, which leads to demand override and as a consequence prices start

soaring in a free-pricing market.

1.5. Import Vs. Indigenous Production

The state and pattern of growth of the economy determine the resin requirement. The

requirements of resin may be fulfilled either through indigenous production and/or through

imports. It is not possible for a developing country to import huge quantities of resin because

of foreign exchange constraints where as it is better for a country to be self-sufficient in its

resin requirements. The products manufactured will substitute the imports, saving foreign

exchange to India.

1.6. Export Potential

There may be large opportunities to become a global supplier of quality resin. Also there

exists abundant market opportunities in the neighbouring regions of Asia, Africa and the

Middle East.

1.7. Employment Generation

Direct Employment

M/s. Sarara Chemicals will generate employment of around 16 full time employees

for operations and administration purpose. The local population will be given

preference for employment as per their qualifications; this will improve their living

standards and livelihood.

A brief description comprising of manufacturing process along with mass balance of the

Product is mentioned herewith as follows:

3.3.1. Urea Formaldehyde Resin:

Urea formaldehyde resins are poly-condensation products of the reaction of formaldehyde

with urea. The relatively easy production of UF resins, their good solubility in water and

absence of colour, make these thermosetting polymers irreplaceable in the manufacture of

many wood based products. Due to the low resistance to humidity of UF resins, the wood

products are suitable for interior use in dry condition. The specifications of the resin product

such as the molar ratio of formaldehyde to urea, solid content, viscosity etc. are adjusted as

per requirement. The manufacturing process diagram is depicted in figure 3.1.

Page 16: Pre Feasibility Reportenvironmentclearance.nic.in/writereaddata/Online/TOR/13... · 2018-02-13 · Pre-Feasibility Report for M/s Sarara Chemicals Page 5 1.4. Demand Supply Gap: Demand

Pre-Feasibility Report for M/s Sarara Chemicals Page 16

3.3.1.1. Manufacturing Process:

The process for the preparation of Urea-Formaldehyde Synthetic Resins comprises:

The UF resin is prepared by reacting Urea with Formaldehyde in a molar ratio of

approximately 1: 2to3 at pH 6 – 11.The aqueous Formaldehyde solution should contain

more than 50% by weight of Formaldehyde. Urea reacts with Formaldehyde under

neutral or alkaline condition to yield Monomethylol Urea, Symmetrical Dimethylol Urea

and Trimethylol Urea depending on nature of reactant.

The resinification process for UF occurs in main stages, addition/ Methylolation and

condensation.

In the Methylolation step Urea and Formaldehyde are reacted under controlled

conditions using an alkaline catalyst. Typically the Methylolation step is carried out with

adjustment of temperature at 80°C and pH 6 to 11. The Mythylolation stage usually

results in a mixture of Mythylolated species, Monomethylol Urea, Symmetrical

Dimethylol Urea and Trimethylol Urea.

This mono and Dimethylol urea may be regarded as the monomer of the urea-

formaldehyde resin.

In the second stage these methylol urea products undergo condensation to form low

molecular weight polymers. The rate of reaction depends on pH. pH is adjusted in 0.5 to

3.5 by using acid. Acid catalyses the reaction in the following ways:

Formation of Methylene Bridge in amino nitrogen facilities in acidic medium

Methylene ether linkages can also be formed in acidic medium

Two types of acid materials can be used, which are classified as direct catalysts & latent

catalysts.

Direct catalysts are inorganic and organic acids, acid salts. They are effective at all

temperatures. The latent catalysts are salts and esters which develop acidity upon

heating.

The solution is refluxed at temperature around 80°C.

The condensation reaction proceeds to a predetermined end point and the resin

intermediate is cooled at 45°C.

At this state the reaction is arrested by raising the pH of the resin at about 6.5 to 9 and

cooled to the ambient temperature by circulating water in jacket and discharged from the

vessel.

3.3.2. Phenol Formaldehyde Resin:

Phenol-Formaldehyde Resin, as a group is formed by a step-growth polymerization reaction

and an exothermic one. It is controlled by a batch reactor as the viscosity of the material

changes rapidly. Since formaldehyde exists predominantly in the solution as a dynamic

equilibrium of Methylene Glycol Oligomers, the concentration of the reactive form of

formaldehyde depends on temperature and pH. The manufacturing process diagram is

depicted in figure 3.2.

3.3.2.1. Manufacturing Process:

The process for the preparation of Phenol-Formaldehyde Synthetic Resins comprises:

A typical phenolic-resin is produced by a batch process in a jacketed autoclave, which

is also termed as a resin kettle.

Molten phenol, formaldehyde in 1:2 ratio and the costic soda is added to the resin

kettle and mixed properly. The mixture is then heated with steam (Temp – 80 –

100°C).

The temperature is controlled by removing the excess heat by water cooling and

refluxing.

At the initial stage of reaction, the heavy viscous resin settles as the bottom layer with

an aqueous layer on top.

A combination of heat and vacuum aids the reaction mixture dehydration process.

When the temperature reaches 130 – 150°C, the resin fuses and is removed from the

kettle/ autoclave.

be flowed to septic tank followed by soak pit. For industrial use, around 2.1KL water will be

required out of which 0.2KL will be used in production process, 0.7KL will be used in boiler,

0.5KL will be required for cooling water makeup and around 0.7KL will be used for kettle

and floor washing. Around 0.7KL waste water is expected to be generated as effluent which

will be treated in ETP. Around 0.6KL treated effluent per day is expected to be generated

which will be used for gardening purpose. So there will be no discharge of waste water. A

water balance diagram is depicted in Fig 3.3.

4. RESPONSIBLE CARE FOR WASTES

4.1. Water Regime

The waste water will be around 700L/D generated from kettle washing and floor washing

will be sent to ETP for treatment. The flow diagram of the treatment process is depicted

below in Fig.4.1.

Fig 4.1: ETP Diagram

4.1.1. Recommended Treatment Process

To treat the wastewater the effluent will be collected in an equalizer tank through screen. It

will be then taken to mixing cum primary sedimentation tank, where Lime solution

(20gm/L) and Alum (4gm/L) or Polyelectrolyte will be dozed for flocculation and

sedimentation. The sludge from the primary sedimentation tank will be taken to sludge bed.

The treated water from primary sedimentation tank will be pH corrected, where acid will be

dosed to get a neutral pH. The wastewater will then to be aerated for 10 hrs with nutrients

and to be settled for another 10 hrs. The effluent is then to be passed through 3 nos.

activated carbon columns. The water will then to be chlorinated. The treated water from tank

will be discharged or reused.

The dry sludge will be stored after collection from the sludge bed.

4.2. Air Pollution

The main source of air pollution will be the flue gas from Vertical Boiler (1 MT/hr) and D.G

Set (50 kVA) contains PM, SO2 and NOx as air pollutants.

In the proposed plant source of air pollution is particulate matter to be generated from the

burning of 20kgs of coal per hour in boiler which is needed to be controlled before discharge

into the atmosphere. To minimize the emission level it is suggested that a cyclone separator

needs to be installed. The outlet of the cyclone separator will be connected to an induced

draft fan and finally to the proposed stack of 30m height. The technical specifications of

Pollution Control Devices are as follows:

The unit will also have one D. G. Set (50 kVA), which will be kept as a stand-by and used in

case of main power failure. The Diesel will be used as fuel for the DG Set and adequate stack

height of 2 m will be provided.

Other source of emission to atmosphere will be from leakage of piping and equipments such

as valves, flanges, pump seals, connections, and compressor seals open end lines and pressure

relief valves. The emissions will not be visually observed but can be measured in relatively

low concentration at each area of source.

4.3. Noise Pollution

The only source of noise generation may be from the D.G. Set, which will be kept as standby

and no other source of noise and vibration from the proposed manufacturing activity except

Plant machineries. The adequate precautions will be taken for abatement of noise pollutions

All the measures would be taken to limit the noise levels at the plant boundary within 75

dB(A) as per the stipulated limits.

4.4. Waste Management

The main source of hazardous waste generation from proposed activity is dried sludge from

ETP and Evaporation residue.

The other source of hazardous waste generation from proposed activity are discarded

containers/ Barrel / bags from storage and handling of raw materials and spent/used oil

generation from plant machinery..

The unit will obtain membership of active Common Environmental Infrastructure TSDF at

Haldia for proper disposal of hazardous waste. The unit has provided dedicated storage area

for the hazardous waste storage within premises having impervious floor and roof cover

system. The details of hazardous waste generation and handling / Management are given in
