CHAPTER 2 PROJECT DESCRIPTION
It is then fed into the centrifuge, where the crystals of Magnesium Sulphate are
separated from the mother liquor. The mother liquor is taken back to the reactor for the
next batch. Water is pumped to the settling tank and the impurities left in the settling
tank are leached 4 or 5 times with water till it is free from Magnesium Sulphate. Then
it is filtered through a filter press and stored in weak solution tanks. The filter cake
obtained in the filter press is dried in the drying yard along with the un-reacted ore
removed from the settling tank periodically, pulverized, packed, stored and sold. The
Magnesium Sulphate crystals obtained from centrifuge is packed and dispatched, or it
is dried in the MgSO 4 drying yard and packed depending upon the requirement of the
buyer.
Reactor
The main reaction for the manufacture of Magnesium Sulphate takes place here. The
reactor is a circular M.S. tank with a dia. of 3M and a height of 4M placed at a height
of 2M above the ground level Reactor is fitted with an agitator, gear box & electric
motor. Fresh water, mother liquor and weak Magnesium Sulphate solution obtained
from the mud washers are taken to the reactor. Required quantity of LCM (MgO) is
added-Spent Sulphuric acid from the measuring tank is slowly added into the reactor

CHAPTER 2 PROJECT DESCRIPTION
Settling Tank & Weak Liquor Storage Tank
Settling tank is a M.S. tank of 12.5 KL capacity with a size of 2 M x 5 M x 1.25 M.
This tank is used to store the impure MgSO 4 coming from the reactor.
The weak liquor storing tanks are made up of M.S with diameter of 2.4 M and a height
of 2.5 M. These tanks are used to store the weak MgSO 4 solutions.
Crystallizers
These are again made up of Mild steel and are half cylindrical at the bottom and
rectangular at the top. It is provided with stirrers for constant stirring.
Hot concentrated solution of Magnesium Sulphate from the filter press is drained intothese and is allowed to cool slowly to room temperature with constant stirring, when
crystals of MgSO 4 are formed. When the solution reaches the room temperature which
it normally does in 24 hrs it is drained into the centrifuge.
Centrifuge
This is used to separate the crystals of MgSO 4 present in the solution drained from

In this section processing takes place. This section consists of mixer and den (Main &R.P.) and acid feeder. The mixer is a horizontal blending machine having mixing and knee
ding section. Ground rock phosphate and dilute Sulphuric acid is continuously fed into
Mixer in fixed proportion. Due to continuous agitation by rotating paddles. First two stage
of reaction take place over here and the mass is converted into thick slurry. A particular
temperature and suction is maintained over here, for proper reaction. The slurry is
discharged by mixer directly into the other slow moving machine called den. Den retains
the slurry for advancement of reaction. Retention time of material in this section can be
changed based on the process need. A slow speed cutter is installed at the discharge end of
den. The den cutter chops the solid material into fine pieces, before discharging it from
den. The material is discharged by den continuously & slowly up to 85-90 % of reaction is
completed at this stage.
The material being discharged by den is Green Super Phosphate. The balance reaction
continues & is completed slowly, in heap in next few days. Den discharged is shifted &
heaped in Curing yard. The material is directly discharged over rubber conveyer. A set of
conveyer belts is installed in go down for shifting heaping of Green Super Phosphate at
different location in go down for curing. The Green Super reshuffled 2 to 3 times & cured.

CHAPTER 2 PROJECT DESCRIPTION
Pollution Control
In Process:
During acidulation fluorine content of rock phosphate is evolved as SiF4 gas. Fluorine
bearing gases are evolved during the reaction are to be removed before discharge to
atmosphere. The gases evolved during reaction in mixer and den is sucked by a high
suction blower & is scrubbed in circulating water. This section consists of H.V. jet
scrubber, Ventury scrubber, cyclone separator, I.D. fan & Chimney for sucking the gases
from point of generation & discharging to atmosphere at height of thirty Five meter, from
ground level after due cleaning. All the specially designed equipment of the section is
lined with different anti-corrosive materials. This scrubber liquor, namely H2SiF6, is kept
in lined pits for settling. The solid silica in the liquor is separated here & kept. The clear
liquor is kept in storage tanks & is used in process for manufacturing of Green SuperPhosphate.
The H 2SiF 6 liquor can also be used for manufacturing other Fluorine based chemicals,
such as Sodium Silico Fluoride. The silica can be sold or used as filler after sun drying.
As the liquor generated is recycled & used in process hence there will not be any liquid
discharge from the plant.

CHAPTER 3 DESCRIPTION OF THE ENVIRONMENT
3.1 BASELINE ENVIRONMENTAL STATUS
The baseline status of the environment quality in the vicinity of the project site serves as
the basis for identification, prediction and evaluation of the impacts. The baseline
environmental quality is assessed through field studies within the impact zone for various
components of the environment, viz. air, noise, water, and land and socio-economic. The
baseline environmental quality has been assessed in the winter season (December 2010
February 2011) in a study area of 10 km radial distance from the project site.
Knowledge of baseline environmental status of the study area is useful for Impact
Assessment Process of assessing and predicting the environmental consequences of the
significant actions. Significant action depicts direct adverse changes caused by the action
and its effect on the health of the biota including flora, fauna and human being, socio-economic conditions, current use of land and resources, physical and cultural heritage
properties and biophysical surroundings.
Baseline data generation of the following environmental attributes essential in EIA studies
have been studied and included in the report.
1. Meteorology
2. Ambient Air Quality

CHAPTER 3 DESCRIPTION OF THE ENVIRONMENT
3.2 ESTABLISHMENT OF IMPACT ZONE
Deciding whether a proposed action is likely to cause significant adverse environmentaleffects is central to the concept and practice of EIA. Before proceeding for baseline data
generation, it is important to know the boundary limits and framework, so that the data
generated can be utilized for the effective and accurate prediction of the environmental
impact assessment of the proposed project.
3.3 METEOROLOGY
Air borne pollutants is dispersed by atmosphere motion. Knowledge of these motions,
which range is scale from turbulent diffusion to long-range transport by weather systems,
is essential to simulate such dispersion and quality of impacts of air pollution on the
environment. The purpose of EIA is to determine whether average concentrations are
likely to encounter at fixed locations (Know as the receptor), due to the given sources
(locations and rates of emission known), under idealized atmospheric conditions. It is
imperative that one should work with idealized condition and all analysis pertaining to air
turbulence and ambient air or noise pollution should be done with meteorological
conditions, which can at best be, expected to occur.

3.6 AIR ENVIRONMENT
3.6.1 Design of Network for Ambient Air Quality Monitoring Locations
The air quality status in the impact zone is assessed through a network of ambient air
quality monitoring locations. The tropical climatic conditions mainly control the
transport and dispersion of air pollutant emissions during various seasons. The baseline
studies for air environment include identification of specific air pollutants prior to
implementation of the project. The Environmental Impact Assessment (EIA) study
requires monitoring of baseline air quality during one season. Accordingly, air quality
monitoring was carried out in the winter season from Dec. 1, 2010 to Feb. 28, 2011. The
baseline status of the air environment is assessed through a systematic air quality
surveillance programme, which is planned based on the following criteria:
Topography / terrain of the study area Regional synoptic scale climatologically normal Densely populated areas within the region Location of surrounding industries Representation of regional background Representation of valid cross-sectional distribution in downwind direction

3.6.6 Scrubber System Details
The unit have already available Water scrubber of adequate capacity to handle proposed
qty. of SiF 4 gas to be generated.
Fluorine bearing gases are evolved during the reaction are to be removed before
discharge to atmosphere. The gases evolved during reaction in mixer and den is sucked
by a high suction blower & is scrubbed in circulating water. This section consists of H.V
jet scrubber, Ventury scrubber, cyclone separator, I.D. fan & chimney for sucking the
gases from point of generation & discharging to atmosphere at height of 35 meter, from
ground level after due cleaning. All the specially designed equipment of the section is
lined with different anti-corrosive materials. This scrubber liquor, namely H 2SiF 6 , is
kept in lined pits for settling. The solid silica in the liquor is separated here & kept. The
clear liquor is kept in storage tanks & is used in process for manufacturing of Green
Super Phosphate.
In Hot Air Generator:
Flue gas generated due to burning of biocoal will be allowed to Multi Cyclone Dust

The dust laden gases enter the pre- separation plenum
1. Where they meet the low baffle plate
2. The baffle wall protects the sleeves against the direct flow. The air velocity isreduced in the pre- separation plenum. The coarse dust fraction leaves the airflow and falls into the dust collection hopper.
3. The gas laden with the fine remaining dust enters the filter plenum.
4. After deflection by the baffle plate.
5&6. The sleeves (6) fitted over supports (5) receive the flow in the outside. The finedust is deposited on the outside of the filter sleeves.

CHAPTER 3 DESCRIPTION OF THE ENVIRONMENT
When the diaphragm valves have closed, the cleaned filter sleeves are onceagain ready for the normal filter process. All rows of sleeves are cleaned in afixed sequence. The cleaning time is so short that practically always the wholefilter surface of the filter is available. Moreover the necessary compressed airquantity in relation to the flow volume is the same up- and down- line of thefilter.The compressed air impacts are controlled by an electronic timer. Impactedregularity can be continuously set with the electronic timer, depending on thetype and amount of dust.

CHAPTER 3 DESCRIPTION OF THE ENVIRONMENT
3.7 WATER ENVIRONMENT
3.7.1 Design of Network for Water Sampling LocationsThe water quality status in the impact zone is assessed through a network of water quality sampling
locations. The baseline studies for water environment include identification of specific parameters
of the pollutants prior to implementation of the project. The Environmental Impact Assessment
(EIA) study requires monitoring of baseline water quality during one season. Physico-chemical
parameters have been analyzed to ascertain the baseline status of fresh water in the existing surfacewater and ground water bodies. Samples were collected once during the study period for winter
season on December 2010 & February 2011.
The baseline status of the water environment is assessed through a systematic water quality
surveillance program, whic
