  100. 100. POLLUTION CONTROL IN UREA PROCESS
  101. 101. BLOCK DIAGRAM OF EMISSION SOURCES
  102. 102. 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.
  103. 103. 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
  104. 104. Cause Particle Size Dust %of Range Total Condensation products of urea vapours/aerosols 0.5-2.0µm 50 Reaction product of NH3 and isocyanic acid 0.1-3.0µm 20 (HNCO) to form Urea 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.
  105. 105. 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 Prill Tower (Not Scrubbed) Urea Dust NH3 mg/Nm3 kg/t Mg/Nm3 kg/t 35-125 0.5-2.2 35-245 0.5-2.7 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.
  106. 106. •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 to Atmosphere. •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.
  107. 107. •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.

  111. 111. 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.
  112. 112. 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. TREATED FLUE GAS CO2 LEAN SOLUTION Flue Gas Source FLUE (1) (2) (3) (4) (Primary GAS Flue Gas CO2 Solution CO2 Reformer) Pretreatment Absorption Regeneratio Compressio n n CoCO2 Product 2 product CO2 RICH fnfp’I’I’ SOLUTION To Urea Plant
  113. 113. •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. •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. •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,
  114. 114. 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 40C 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 .
  115. 115. The lean solution is cooled to the optimum reaction temperature of 40C 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.
