Chapter 88.5 BAT for Urea and UANBAT is to apply the common BAT given in Section 1.5.BAT for storage is to apply BAT given in [5, European Commission, 2005].BAT is to improve environmental performance of the finishing section by one or a combinationof the following techniques:• apply plate bank product cooling (see Section 7.4.5)• redirecting urea fines to the concentrated urea solution• select proper size of screens and mills, e.g. roller or chain mills• apply surge hoppers for granulation recycle control• apply product size distribution measurement and control.BAT is to optimise the total energy consumption for urea production by applying one or acombination of the following techniques:• for existing stripping installations, continue applying stripping technology• for new installations, applying total recycling stripping processes (see Sections 8.4.2, 8.4.3and 8.4.4)• for existing conventional total recycling installations, only in the case of a substantial ureaplant capacity increase, upgrading to stripping technology (see Section 8.4.7)• increase heat integration of stripping plants (see Section 8.4.8)• applying combined condensation and reaction technology (see Section 8.4.9).BAT is to treat all exhaust gases from the wet sections by scrubbing, taking into account thelower explosion limit and to recycle the resulting ammonia solutions to the process (e.g. seeSection 8.4.5).BAT is to reduce ammonia and dust emissions from prilling or granulation and to achieveammonia emission levels of 3 – 35 mg/Nm 3 , e.g. by scrubbing or optimising the operationconditions of prilling towers, and to re-use scrubber liquids on-site (see Section 7.4.11). If thescrubbing liquid can be re-used, then preferably by acidic scrubbing, if not, by water scrubbing.In optimising the emission levels to the values mentioned above, it is assumed that dustemission levels of 15 – 55 mg/Nm 3 are achieved, even, with water scrubbing.Where process water with or without treatment is not re-used, BAT is to treat process water, e.g.by desorption and hydrolysation and to achieve the levels given in Table 8.20 (see Section8.4.12). If in existing plants the levels cannot be achieved, it is BAT to apply subsequentbiological waste water treatment.NH 3UreaAfter process watertreatmentNew plants 1 1Existing plants

Chapter 99 AN AND CAN9.1 General informationAmmonium nitrate (AN) is used extensively as a nitrogenous fertiliser. The main marketableproducts are: hot solution of ammonium nitrate, ammonium nitrate containing 33.5 – 34.5 %nitrogen and calcium ammonium nitrate containing less than 28 % nitrogen. The worldproduction of AN solution (ANS) is estimated to be 40 – 45 Mtonnes per year.Calcium ammonium nitrate (CAN) is obtained from AN solution by mixing with dolomite,limestone or calcium carbonate and represents Western Europe’s most applied fertiliser product.Plants for the production of AN and CAN generally produce from a few hundred tonnes per dayup to 3600 tonnes per day.Other products, similarly obtained by mixing are magnesium ammonium nitrate, MAN(addition of relatively large quantities of dolomite), ammonium sulphate nitrate, ASN(addition of (NH 4 ) 2 SO 4 or H 2 SO 4 ) and NS fertilisers (generally based on gypsum).Fertiliser products must comply with EU regulation 2003/2003/EC. AN and CAN fertiliserscontaining an excess of the specified thresholds of ammonium nitrate are classified as oxidisingsubstances under the UN Transport Regulations.Country Company LocationYearstartupCapacityin kt/yrAustria Agrolinz Linz 1989 630Belgium BASF Antwerp 1990 650CzechRepublicLovochemie Lovosice 1991 415France Grande Paroisse Mazingarbe 1971 250GermanyYaraCommentRostock 1985 633 Line 1Rostock 1985 633 Line 2Lithuania Achema Jonava 2003 415 Status unknownTheNetherlandsDSMGeleen197919931150Anwil Wloclawek 2000 500Poland Zaklady Azotowe Kedzierzyn 1987 616Zaklady Azotowe Tarnow 1965 360Portugal Adubos Alverca 1961 290Chemko Strazske Straske 1997 75SlovakiaSala NadDusloVahom1976 500Spain Fertiberia Avilés 1970 250Switzerland Lonza Visp 1982 120Table 9.1: CAN production plants in the European Union as of July 2006[154, TWG on LVIC-AAF, 2006]Number of plantsand status unknownLarge Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers 363
