• In Aonla Unit, Lean NG is being supplied by

GAIL through HBJ pipeline which results in CO2

shortage for conversion of full Ammonia

production to Urea leading to Ammonia stock

buildup in the plant.

• CO2 recovery has been installed to meet the

shortfall of CO2.

• CO2 recovery Plant is recovering 450 MTPD of

CO2 from the Primary Reformer flue gases of

Ammonia-I (A CDM Project).

POLLUTION CONTROL IN UREA PROCESS

BLOCK DIAGRAM OF EMISSION SOURCES

Urea Process generates process water containing NH3-6%,CO2-2% &

Urea-1.0% by weight.

The principal source of this water is the synthesis reaction whwre 0.3 tonnes of

water is formed per ton of Urea.

2NH3+CO2→CO(NH2)2+H2O

The other sources of water are ejector steam,flush and seal water and steam used

in the waste water section.

The principal sources of urea ,NH3 and CO2 in the process water are:-

a)Presence of Ammonia in the urea solution feed to the evaporator

b)The formation of Biuret and the hydrolysis of urea in the evaporators,both

liberating NH3

2CO(NH2)2 →H2NCONHCONH2+NH3

CO(NH2)2+H2O →2NH3+CO2

c)Direct carry over of Urea from the evaporator separators to the

condensers(Physical entraiment)

d)The formation of NH3 from the decomposition of Urea ti Isocyanic Acid

CO(NH2)2 →HNCO+NH3

The reverse reaction occurs on cooling the products in the condensers.

(e) Off-gases from the recovery/recirculation stage absorbed in the process water.

(f) Off-gases from the synthesis section absorbed in the process water.

(g) Flush and purge water from pumps.

(h) Liquid drains from the recovery section.

Treated water : Urea-5 ppm,Ammonia-30 ppm

The purpose of the water teatment is to remove Ammonia,CO2,and Urea from the

process water and recycle the gases to the synthesis.This ensures raw material

utilisation is optimised and effluent is minimised.

Prill Tower Emissions

The prill tower is a major source of emission in urea plants. The large volumes of

discharged untreated cooling air contain particulate urea dust (1-2kg/t) as well as

NH3 (0.7-1.0kg/t).

Causes of dust formation

Prill satellites and undersize prills 10-100µm 5

Crushing, abrasion and attrition on the tower floor 1-100µm 5

Seeding dust 1-20µm 20

Towers with natural draft cooling are reported to have less dust emission than

towers with forced/induced draft air cooling.

The lower air velocity and product mass per m 3 of tower volume reduces attrition and carryover in the natural draft towers.

Operation and maintenance items significantly affecting dust formation

•Fouling of the prilling device causing wider spread in prill granulometry.

•High melt feed temperature causing increased evaporation.

•High prill temperature at the tower base. The largest prills may not have solidified sufficiently and will fracture on impact.

•Dust emission is approximately proportional to prilling tower capacity.

•High air velocities and the air velocity distribution cause coarse dust to be entrained.

•Weather conditions e.g. relative humidity, temperature can affect the air quality/quantity.

•Unequal pressure in the prilling device causing a broad spread of prill size.

Prill tower emission abatement

Selection of the appropriate equipment for existing plants can be a complex issue.

Dry dust collectors, irrigated electrostatic

precipitators and irrigated dust scrubbers have been considered for dust

abatement but few have been commercially proven

. Wet scrubbers seem to be more attractive than dry dust collectors. Recovery of

the NH3 from the emission (for example by

aqueous scrubbing) is very inefficient due to the low partial pressure of the gas in the discharged air.

Existing prilling plant performance

Causes of dust formation

The following reflects some speculations about the causes of dust formation .

•Urea vapour formation during hot spraying of the urea melt and its subsequent

condensation/solidification into small

•(0.5-3.0mm) particles. The vaporisation becomes negligible when the melt concentration is reduced to 95%.

•Reaction product of NH3 with isocyanic acid to form Urea.

•Entrainment of fine dust in the air.

•Solidification of sprayed molten urea droplets prior to coating due to excessive• air flow.

•High vapour pressure of sprayed molten urea.

•High or low temperature, producing soft or brittle granules.

•Inter-granular friction causing surface abrasion

Feasible and Available Emission Abatement Techniques

Gaseous emissions

•Scrubbing of off-gases with process condensate prior to venting inerts toAtmosphere.

•Wet scrubbing of prill tower and granulation air to recover urea and NH3.

•Connection of ammonia pump safety relief valves/seals to a flare; connection of

• tank vents to the plant main stack• or other safe location.

•Impact of granules with the metal surface of the drum.

•Dust reduction by producing granular rather than prilled product.

•Bag filtration of dust laden air from transfer points, screens, bagging

machines, etc. coupled with a dissolving system for recycle to the process.

•Flash melting of solid urea over-size product for recycle to the process.

•Collection of solid urea spillages on a dry basis

Liquid emissions

Treatment of process waste water for recovery of urea, NH3 and CO2.

Improved evaporation separator design to minimize urea entrainment.

Provision of adequate storage capacity for inventory to cater for process upset

and shut-down conditions.

•Provision of submerged tanks to collect plant washings, etc. from drains for recycle to the waste water treatment section.

•Use of mechanical seals instead of gland packing for pumps.

•Use of closed circuit gland cooling water system for reciprocating pumps.

•Replacement of reciprocating machinery with centrifugal type.

Solid waste

In the modern urea processes although the sophisticated handling of product

urea has reduced the chances of spillage,

still the formation of lumps and some spillage of urea prills cannot be ruled out.

To meet this exigency, a urea melting

system to employed. The melt urea obtained from the spillages and sweeping should be suitably recycled in the processes.

CARBON DIOXIDE RECOVERY (CDR) FROM FLUE GASES OF PRIMARY

REFORMER AT IFFCO AONLA UNIT

IFFCO, a premier fertilizer company has installed and commissioned Carbon

Dioxide Recovery (CDR) Plant at it‟s Aonla & Phulpur Units for recovery of CO2

from Primary Reformer Flue Gases based on the technology from M/s Mit

subishi Heavy Industries (MHI) Limited, Japan and Detailed Engineering from M/s

Tecnimont ICB (TICB) Private Limited, Mumbai.

The CO2 recovered from flue gases makes up for deficit of CO2 due to use of Lean

NG / R-LNG & leads to conversion of all the Ammonia produced to Urea, thus

avoiding Ammonia stock build up. The recovery of CO2 from flue gases also

reduces CO2 emissions (Green house gas) to atmosphere and thus contributes to

cleaner environment.

Carbon Dioxide (CO2) Recovery from Flue Gases.

The CO2 Recovery from flue gases is having following distinctive advantages:

It reduces CO2 emissions (Green house gas) to atmosphere, contributes to

cleaner environment, conserves carbon intensive fossil fuels like Naphtha and

thus has a great potential to be covered under Clean Development Mechanism

(CDM) of UNFCCC. The trading of certified emission reductions (CERs) through

CDM generates additional revenues & increases the viability of the CDR Project.

Production of additional CO2 from CDR unit in place of costlier Naphtha feed,

shall decrease cost of production of Urea and hence shall reduce Government

of India‟s annual subsidy outgo.

SALIENT FEATURES OF CDR PROJECT

The following are the salient features of CDR Project ordered on M/s TICB,

Mumbai & M/s MHI, Japan :

Source of CO2 : Flue gases from Primary Reformer stack of

Ammonia Plant

Plant Capacity : 450 MTPD CO2 (100% basis)

MHI CDR PROCESS

The CDR plant consist of four main sections; 1) Flue gas pre-treatment section,

2) CO2 absorption section, 3) Solution regeneration section, 4) CO2 compression

section. The following block flow diagram shows the plant configuration.

•1) Flue Gas Pre-treatment

The hot flue gases at about 150 – 180 0C are cooled to 42 0C, using flue gas

cooling system prior to the CO2 absorption in Absorber, to optimise KS-1

solution consumption & lower flue gas temperature which is favourable for

CO2 absorption.

The Flue gas water cooler is a packed column with SS structured packing.

Flue gas is cooled in the upper packing section of the Flue gas water cooler

by direct contact with water supplied from top of the tower. Circulating water

is cooled by a plate type heat exchanger. De-SOx (SOx removal) is carried out

in the lower packing section of Flue gas water Cooler by circulating dilute

caustic solution. Any slippage of SOx in the Flue gas from Flue gas water

cooler to CO2 Absorber shall cause KS-1 Solvent degradation.

A Flue gas blower has been provided at downstream of Flue gas water cooler

to draw the flue gas from existing stack to overcome the pressure drop

across Flue gas water cooler & CO2 Absorber.

•The cooled flue gas from the Flue gas water cooler is introduced into the bottom

section of the CO2 absorber through flue gas blower. The flue gas comes in

contact with the KS-1 solution on the surface of the packing in absorption section,

•2 ) CO2 Absorption

The CO2 absorber is a packed bed column with SS structured packing. The CO2

absorber has two main sections namely, the CO2 absorption section in the lower

part, and the treated flue gas washing section in the upper part.

where CO2 in the flue gas is absorbed by the KS-1 solution. The flue gas then

moves upward into the treated flue gas washing section in the upper part of the

CO2 absorber . The flue gas comes in contact with water for washing of entrained

amine content, as well as for cooling down to maintain water balance within the

system. The treated flue gas is exhausted from the top section of the CO2

absorber at sufficient height.

Rich solution from the bottom of the CO2 absorber is pumped to the Regenerator

through Solution heat exchangers to exchange heat with hot lean solution from

Regenerator bottom.

•3) Solution Regeneration

The Regenerator is a packed column with random SS packing, where the rich solution is

steam-stripped and CO2 is removed from the rich solution.

The rich solution (from the bottom of the CO2 absorber) after exchanging heat with the hot

lean solution (from bottom of regenerator) in “Solution heat exchangers” enters the upper

section of the regenerator. The regeneration heat is indirectly supplied by LP Steam

through re-boilers.

The overhead vapor from Regenerator column is cooled to 40C in Regenerator

condenser using cooling water. The condensed water is returned from the Regenerator

reflux drum to the top of the Regenerator by the Regenerator reflux pump to enhance

CO2 purity, remove KS-1 mist entrained in CO2 gas & maintain water balance in the

system .

The lean solution is cooled to the optimum reaction temperature of 40C by the

Solution heat exchangers and the Lean solution cooler prior to being fed to the CO2

absorber. 10% of the lean solution flows through a carbon filter system to eliminate

oil and soluble impurities. The mechanical guard filters are provided before and

after the carbon filter to remove insoluble particulate.

•4) CO2 Compression

The CO2 product gas is compressed by the CO2 compressor & then cooled in a

Compressor discharge cooler to supply product CO2 at a pressure of 0.8 Kg/cm2g

& temperature of 40 C at CDR plant battery limit. The product CO2 having purity

around 99.8 %(v/v) is sent to the existing Urea Plants by interconnection with

existing CO2 header.
