EMISSION-STANDARDS
The emission standards for Cement, Thermal Power, Iron & S.teel, Fertilizer
(urea), Nitric and Sulphuric Acid plants, six out of twenty industries listed
in the Schedule in Chapter VII under Section 54 (3) of the Air (Prevention
and Control of Pollution) Act, 1981 are given below in abstract�
As prescribed in the Air (Prevent-ion and Control of Pollution) Act, 1981
Section 17 ( l) (g), the emission standards for the six air polluting industries
mentioned above have been laid down. The emission standards for other
industries covered in the Schedule will be brought out subsequently. The
rationale for adopting these standards are given in the report.
These standards are applicable up to December, 1 9 86 and will be reviewed
again in January, 1987 based on experience and input from the monitoring
data obtamed in this.· period. The stack monitoring shall be done as prescribed
by the Central Pollution Control Board.
The State Board may adopt standards that are more stringent than thoS'e
given below depending on the location of the industries ahd specially if it
m a protected area. They shall not, however, relax the standards ..
A protected area is one that it already polluted from being in a metropolitan/
industrial location or the area is sensitive because of its proximity to national
parks, forests historical monuments and health resorts.

CEMENT
Sources of Emission
Generally particulates are emitted from the following sources ;
i. Rotary Kiln (Dry, Wet or Semi-Dry).
11. Raw Mill, Clinker Cooler.
iii. Finish Grinding.
iv. Packaging, .:)torage (Silos).
Besides emission is also associated with pul ver isa ti on of coal.
The control of particulate m the last three sources, namely, finish grinding,
packaging and storage is usually practiced in India (Refer Annexure-1) at
the highest possible level because of the urge for saving the products and
raw material both in old and obviously new plants. Furthermore, it is easier
to control from these three sources because of conditions of opera ti on.
But in case of the rotary kiln the control of emission is difficult because
of elevated flue gas temperature and the presence of carbon monoxide.
Due to technological limitations, most of the countries had to provide higher
allocation of emission load to th� rotary kiln when all the above 4 sources
are considered together. To site this the Canadian example is used, where
the controlled emission in terms of daily quantum are as furnished in Table
I.

It may be seen that about 50 percent of total quantum of emission is permitted
from the rotary kiln after approoriate control.
Data provided in Table 2 suggest that about 3 to 4% of product 1s emitted
when no control equipment is ·in position. If the industry tries to reduce
this emission to 0.05 percent of product then the efficiency of control ranges
between 98.3 to 98.8 percent, which must be within the technological capa
bility of the country.

NOTE It may be taken that approximately 3 to 4% of product is the
emission (uncontrolled) from rotary kiln.
The control devices associated with the rotary kiln should be capable of
attaining an efficiency exceeding 99 percent. Hence the efficiency ranges
prescribed here as 98.3 to 98.8 percent is quite conservative, and it is, there
fore, expected that rotary kiln should not emit more than 0.05 percent of
product after installing control devices. The corresponding concentration
of emission is given in Table 3 for the 3 units. The concentrations range
between 140 to 320 mg/Nm3•

For rotary kiln the daily quantum of emission .ts to be computed on the basis
of 0.05 tonne per tonne of cement l?�oduced. The average concentrations
to be maintained by the industry may be computed on the basis· of the air
flow rate, expressed in N m3 /hr mainta.ined in the kiln. It is also expected
that emissions from cement plants of capacity less . that 200 tpd would be
comparatively lesser than a large cemen,t plant. Also keeping in view that
certain areas would haxe to environmentally protected because it is already . , ·
polluted or is a sensitive area, the fo!Jow ing standards are adopted :

to limit the particulate matter emission. For keeping the sulph\Jr dioxide
level in the ambient within the air quality standards, the method required
shall be by maintaining a minimum stack height.

Sampling conducted at a recently commissioned 200 MW Thermal
Power Station showed that 99.78% removal of particulate matter
can be achieved with ESPs of latest indigenous design. The details
are provided in Table 2.2.

Source : Bharat Heavy Electricals Limited (BHEL)
ln developing the standards it is considered that category (b) plaAts
must install ESPs to achieve 99.78% removal as demonstrated at the
above plant. A standard of 1 50 mg/Nm 3
is proposed in these cases.
3.(a) In addition to the size of the boilers, qualified above, additional consi
der a ti on should be given to its age and its location. The age is impor
tant fr:om the point of view of the cost-benefit aspect and the location
from its en"4ironmental impact.
3.(b) BHEL came out with ·their improved ESP design in 1979. Therefore,
all plants commissioned after 31st December, 1979 are being classified
as new plants. Even if the boiler has been installed prior to 1979,
the plant will be· classified as new, in this standard, if the ESP has
been installed after December, 1979. New plants should meet an
emission level of 350 mg/Nm3
(equivalent to about 99.4% collection
efficiency). This is more relaxed than the standard for boilers greater
than 200 MW because the emission load from the smaller boilers will
be less. Further, for older plants, a standards of 600 mg/N m3
is
proposed because these plants may have constraints on both funds
Finally in areas where the environmental quality has to be protected
a standard of 1 50 mg/Nm3 is being adopted.

150 mg/Nm 3
200 MW and above 150 mg/Nm 3 150 mg/Nm 3
Stade Height Requirement for Sulphurdioxide Control
To maintain a healthy ambient air quality the stack height for boilers
should be as follows
Boiler size Stack height
200 MW and More to Less than 500 .MW 220 Metres
500 MW and More 275 Metres
Less than 200 MW H = 14 (Q)0.3
Q = Sulphur dioxide emission in kg/hr
H = Stack height in metres
Flue Gas Desulphurization
No s.tandards for sulphur dioxide emission is being prescribed, the control
being effected through the height of the stack.
For plants having boilers of 500 MW and more, necessary space has to be
provided for installing flue gas desulphurization device, should there be a
requirement in the future.

INTEGRATED IRON AND STEEL
l. Sources of emissions
2.
The sources of pollutant emissions are :
i. Sintering
ii. Coke Oven
rn. Blast furnace
iv. Steel making (oxygen lancing)
There will also be emissions from captive power plant and coal handling
operations which are not considered here.
Sintering plant
From the sintering plant, dust emission is expected to be 2.5 percent
of product. A survey of the steel plants in the country reveals that
flue gas collection system in the sintering plants are such that it
is not possible to correctly measure the flow rate and the dust concen
tration. No data otherwise is available to estimate the raw emission
in terms of concentration.
In the absence of any monitoring data it• is considered that we will
have to go by the achiev$ibility of venturi scrubber, bag filter or ESP,
preceded by cyclones if necessary, in which case it is possible to achieve
an outlet emission of 150 mg/Nm3. Therefore the emission limit
for sintering plant is adopted as 150 rng/Nm3.
3. Coke Oven
In the coke oven, process coal is heated in a battery to drive away
the organic matter and other impurities to obtain coke.
Heat source is coal or gas. About 60% of the total coke plant parti
culate emissions are accounted. for b'y coke oven charging and about
30% by discharging (WHO: ESP/83.49). Attempt should be made to
() "U () OJ m z < (j) () CD :J ....... ....,

- 13 -
control emissions both from coke oven charging as well as from dis
charging. No limit is proposed for the coke oven section.
4. Blast furnace
5.
6.
The top gas from the furnace which contains significant concentration
of particulates, after necessary cleaning, is used as a source of energy
in all the steel plants. Tapping is also a source of particulate emission
which may be required to be controlled. Considering the amount
of emission from the Blast furnace, no limit is proposed.
Steel making process with oxygen lancing
The emission from this section would be normally high only during
oxygen lancing. The gas would contain iron particles and be of high
temperature. In view of the above, high energy venturi scrubber
or bag filter is the recommended control equipment. However, it
is noted that ESP can also be used. In the absence of any monitoring
data, a limit is adopted based on achievability. During non-lancing
period the emission can be controlled to 150 mg/N m3
or so, the figure
of 400 mg/N m3 is adopted to take care of the lancing period.

FERTILIZER (UREA)
1 . Background
2.
3.
There are a number of nitrogenous, phosphatic and complex fertilizer .
manufacturing plants in the country. Some of the plants have captive
sulphuric acid and nitric acid (intermediates) manufacturing uni ts;
the emission limits for these units will be as per those developed
separately for the respective acid plants. Emission limits for fluoride
in case of phosphatic fertilizer plants is under preparation. The various
nitrogenous fertilizers are ammonium sulphate, ammonium nitrate,
calcium ammonium nitrate, ammonium chloride and urea. Plants
manufacturing urea are taken up for the present.
Source of emission
() "U () OJ m z < (j)
The source ·-of emission of particulate matter urea dust from the urea () CD
plants is the prilling tower. Prilling tower use cooling air for the urea � ....,
prills and are mostly discharged from the top. In this process, the CD -
molten urea is sprayed from the top of the prilling tower and the
cold air flows counter current, which picks up fine particles of urea
alongwith moisture. The size of the particles range from 2 to 200
mJCrons.

The air flow rate through the prilling tower is 400 - 500 m3 /hr per : tpd (tonne per day) of urea (Fertilizer Association, India). The dust
content of exhaust air could be around 300 - 500 mg/N m3. In order
to arrest these particles a scrubber followed by a demister should
be provided. The expected efficiency of removal is around 90%.
Therefore the limit for particulate emission urea dust through the

NITRIC ACID
I • Background
2.
The ammonia oxidation processes account for 90% of the nitric acid
production in the country. The processes are divided into four basic
steps :
Oxidation of NH3 to NO
Oxidation of NO to N02
Absorption of N02 in water
Concentration of HN0 3
Sources of emission
The main source of emission is the spent (tail) gas from the absorption
tower in which N02 is absorbed in water to produce weak (50%-70%)
nitric acid. The pollutants are primarily nitric oxide, nitrogen dioxide
and trace amounts of nitric acid mist. The spent gas after energy
recovery and acid mist removal is normally emitted through a stack.
The uncontrolled emission is estimated to be 25 to 27.5 kg of i'Y.O/ tonne of weak HN03 produced. (EPA:AP-42, Part A). As per data
reported by an Indian plant the uncontrolled emission level 1s in the
range of 2000-4000 pp rn.
In general, the quantity of NO emission is x kinetics of the nitric acid formation reaction.
variables that increase tail gas NO emission are x
directly related to the
The specific operating
I. insufficient air supply, which results in incomplete oxidation
of NO
2. low pressure in the abosorber
3. high temperature in the cooler-condenser and absorber
4. production of an excessively high-strength acid and

5. operation at high throughput rates, which results in decreased
residence ti me in the absorber.
There will also be emission from the tower in which concentration
of the weak acid 1s carried out and is estimated at 0.1 to 2.5 kg/tonne
(EPA: AP-42, Part A).
3. Control of Emission
The stack gas before release to the atmosphere can be treated by
a catalytic combuster or on an alkaline scrubber. In the catalytic
combustor tail gases are heated to ignition temperature, mixed with
fuel (natural gas, hydrogen, or a rnix ture of both), and passed over
a catalyst. The reactions that occur result in the successive reduction
of N02 to NO. The ex tent of reduction of N02 to NO in the combustor
is, in turn, a function of plant design, type of fuel used, combustion
temperature and pressure, space velocity through the combustor, type
and amount of catalyst used and reactant concentrations.
The expected efficiencies of control in the case of catalytic combustor
are as follows (EPA: AP-42)
Type of fuel Control efficiency
Natural gas 78.97
Hydrogen 97 - 99.8
75% Hydrogen + 25% Natural gas 98 - 98.5
The other method of NO removal is by scrubbing. As per data reported x
by an Indian plant, from an inlet concentration of 2000-4000 ppm,
NO can be reduced to about 300 ppm, providing an efficiency of x
about 90%.
4. Emission standard
Considering 90% as the achievable control, an emission limit of 3
kg NO /tonne of weak acid produced (before concentration) averaged x
ovt. ,· a 2 - hour period, is adopted.

SULPHURIC ACID
Sulphuric acid is produced mainly by the Contact Process. This involves
the catalytic conversion of sulphur dioxide, produced by burning sulphur,
into sulphur trioxide, which is then absorbed in strong sulphuric acid.
2. Source of Emission
Pollutants emitted from the plants are so2, so3 and acid mist. Nearly
all sulphur dioxide emission from sulphuric acid plants are found in
the exit gases of the so2 to so3 converter. The amuunt of so2 emitted
is inversely proportional to the conversion efficiency. The conversion
is affected by the following :
i. number of stages in the catalytic converter
ii. the amount of catalyst used
iii. the temperature and pressure and
1v. the concentration of reactants (502 and 02).
Uncontrolle,d em1ss1on for var10us conversion efficiencies are furnished

In addition to exit gases, small quantities of sulphur ox ides are also
emitted from storage tank vents, loading operation, sulphuric acid

3. Emission limits
Recent monitoring carried out by the Central Board at two plants

In both the plants the so2 emiss10ns are uncontrolled. From the emis
s10n data and conversion efficiencies (Table 1) it may be presumed
that 99% and 96.5% conversion efficiencies are achieved in double
and single absorption processes, respectively. But the double absorption
process is expected to achieve 99.7% conversion, the corresponding
so2 emission being 2 kg/tonne of H25o4 (100%). Adopting 99.4%
as the stable average efficiency, an emission limit of 4 kg/tonne of
H2so4 averaged over 2 hour, in case of double contact double absorption
process.
Plants having single absorption process are required to reduce 502 emission
for instance, by absorption in sodium sulphite or bisulphite and recycling
the same. A limit of 1 0 kg/tonne of H 2so 4 ( 100%) averaged over
2 hours is suggested as the limit for 502
em1ss10n for these plants.

GUIDELINES FOR MINI MU M STACK. HEIGHT
Plant Type
For all plants except Thermal Power Plant
Stack Height
30 m
2. For plants where the sulphur dioxide emission is estimated as Q(kg/hr)
the stack height, H in metres is given by
3.
4.
H = 14 (Q)0.3
For plant� where the particulate matter emission 1s estimated as Q
(tonnes/hr) the stack heigt1t, H in metres is given by
H = 74 (Q)0.27
If by using the formula given m 2 or 3 above, the stack height arrived
at, is more than 30 m then this higher stack height should be used.
In no case should the height of the stack be less than 30 m.
