Transcript of "05 Croatian Meet Industry Using Ammonia Vladimir Soldo"

  1. 1. University of Zagreb Faculty of Mechanical Engineering and Naval Architecture JOINT MEETING OF THE REGIONAL OZONE NETWORKS FOR EUROPE & CENTRAL ASIA (ECA) AND SOUTH ASIA (SA), ISTANBUL, TURKEY, 26-30 APRIL 2010 PIK Vrbovec Croatia: Meat industry using ammonia Vladimir SOLDO National consultant in the project HPMP in Croatia
  2. 2. <ul><li>ODS phase out project in Croatia </li></ul><ul><li>Faculty of Mechanical Engineering and Naval Architecture (FMENA) University of Zagreb has been the national consultant in many phase out projects in Croatia (RMP, TPMP, Chiller demonstration projects, HPMP) since 1999 . </li></ul><ul><li>FMENA is the national training center in Croatia (RMP, TPMP) </li></ul><ul><li>with m ore than 2200 service technicians trained and certified . </li></ul><ul><li>Project leader : prof.dr.sc. Tonko Ćurko </li></ul>Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010

  4. 4. 1. INTRODUCTION <ul><ul><li>Meat industry PIK Vrbovec (established in 19 38 ) opened the most modern production plants in the south-east of Europe in 2008. </li></ul></ul><ul><ul><li>The old factory used ammonia, but the system had the charging of about 30 tons. </li></ul></ul><ul><ul><li>New plants after the reconstruction of the old cold stores and refrigerating systems and the installation of new plants with the total cooling area of 25.000 m2, has charging of about 20 tons. The total cooling capacity of plants is 10 MW. </li></ul></ul><ul><ul><li>For the freezing cold stores and tunnels a direct ammonia refrigerating system is used. </li></ul></ul><ul><ul><li>For production cold stores, where people work an indirect ammonia refrigerating system with four chillers is used. </li></ul></ul>Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  5. 5. DIRECT SYSTEMS FOR FREEZING COLD STORES AND TUNNELS System schematic Charging of ammonia - 14 . 9 tons Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  6. 6. Indirect cooling system - chillers Secondary coolant is a 35 % mixture of propylene glycol and water Charging per chiller is 200 kg of ammonia Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  7. 7. Production cold stores with indirect cooling system This is a fully automated production line. Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  8. 8. Distribution of cool ed air Rashladne komore Discharge distribution socks Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  9. 9. The plan of rail layout. The meat is hung on hooks on roller carriers. Rashladne komore Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  10. 10. Freezing plant Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  11. 11. MACHINERY ROOM Oil is cooled by water Screw compressors Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  12. 12. <ul><li>S afety system – a v ery important part of plant . </li></ul>SAFE OPERATION <ul><li>All connections and valves of the ammonia distribution system are in the technical hall, outside of cold stores. </li></ul><ul><li>In case of ammonia leakage (200 ppm) water sprays are used and the ventilation system is turn ed on. The a bsorbed ammonia is stor ed in special tanks. </li></ul>Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  13. 13. Students’ technical excursion A common practise of the faculty (FMENA) is to take students for study visit of refrigerating plants. The visit was very useful to students because they could see how modern systems using natural refrigerant operate. Study visit , PIK Vrbovec, 29 May 2009 Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
  14. 14. CONCLUSION <ul><li>For the past few years with installation and reconstruction under way, production has been increased by 3 times, and the total charging of ammonia has decreased by one third. </li></ul><ul><li>A mmonia as a natural refrigerant is the first choice in industry refrigerating systems </li></ul><ul><li>Ammonia system in meat industry PIK Vrbovec with the charging of almost 20 tons is a sample application with safe and efficient operation. </li></ul><ul><li>In the r econstruction of old cold stores and refrigerating systems in meat industry PIK Vrbovec and in the installation of new plants with a total cooling area of 25.000 m2 all new standards have been applied . </li></ul>Joint meeting of the R egional O zone N etworks for E urope & C entral and S outh A sia, I stanbul, T urkey, A pril 2010
