  1. Major Ideas in Industrial Chemistry Elective and Related IT Learning Materials Dr Cheung Shiu Fai Editor, Educational Publishing Division

  2. Overview of the seminar • Curriculum comparison between NSS, CE and AL for industrial chemistry • Main topics in industrial processes • Demonstration of IT learning materials • Industrial chemistry-related courses in university education and career prospects

  3. Curriculum comparison between NSS, CE and AL for industrial chemistry

  4. Curriculum comparison between NSS, CE and AL for industrial chemistry

  5. Curriculum comparison between NSS, CE and AL for industrial chemistry

  6. Curriculum comparison between NSS, CE and AL for industrial chemistry

  7. Curriculum comparison between NSS, CE and AL for industrial chemistry New contents compared to HKCEE and HKALE (adopted from NSS Chemistry Curriculum): 1. Conversion of raw materials to consumer products as illustrated by the production of fertilizers (Discovering Chemistry 54.1&2) 2. Advancement of industrial processes as exemplified by the conversion of methane to methanol (Discovering Chemistry 54.4)

  8. Curriculum comparison between NSS, CE and AL for industrial chemistry New contents compared to HKALE (adopted from NSS Chemistry Curriculum): 1. Calculate the atom economy of a chemical reaction (Discovering Chemistry 55.1) 2. Relate principles of green chemistry and practices adopted in the industrial processes as exemplified by the manufacture of acetic acid (ethanoic acid) (Discovering Chemistry 55.2) 3. Evaluate industrial processes using principles of green chemistry (55.2)

  9. Topics in industrial processes Petrochemical industry (50.2) Processes that convert raw materials into value-added products (50.1) Two-step fermentation process Organic industry Vitamin C industry (50.3) Reichstein process Definition Methanol industry (54.4) Types Industrial processes Inorganic industry Ammonia industry (54.2) Plant site selection criteria (54.5) Chloroalkali industry (54.3) Common processes Resource availability Environmental impact Transportation capacities Mercury cell process Membrane cell process Diaphragm cell process

  10. Connections between industrial processes and Compulsory Part • Fractional distillation of liquid air into N2 for Haber process • Fractional distillation of crude oil • Cracking • Electrolysis of different concentrations of NaCl • Methods to determine the rate of a reaction  • Effect of changes in concentration and temperature on chemical equilibrium Chapter 1 Supplementary Information Chapter 21 Chapter 24 Chapter 33 Chapter 38 Chapter 41

  11. Petrochemical industry (50.2) Organic industry Types Industrial processes

  12. Types Industrial processes Inorganic industry • Students should be able to • Explain the physicochemical principles involved in the production of ammonia • Explain how industrial processes such as the Haber process often involve a compromise between rate, yield and economic considerations • Abstracted from Chemistry Curriculum and Assessment Guide (Secondary 4 - 6) Ammonia industry (54.2)

  13. CAL Program – Effects of pressure and temperature in Haber process Suggested Learning and Teaching Activities: “Using computer modelling to study an industrial process and to control the production of a chemical plant” Abstracted from Chemistry Curriculum and Assessment Guide (Secondary 4 - 6)

  14. Animation – Effect of catalyst on chemical equilibrium in Haber process Students should be able to Describe the applications of catalysis in industrial processes with examples such as iron in the Haber process… Abstracted from Chemistry Curriculum and Assessment Guide (Secondary 4 - 6)

  15. Types Industrial processes Inorganic industry Chloroalkali industry (54.3) Common processes Mercury cell process Membrane cell process Diaphragm cell process

  16. Three cell processes in chloroalkali industry has different: • Structure of electrochemical cell • Ion distribution in anodic/ cathodic compartment • Cathodic/ anodic reactions • Concentration of products • ……

  17. Organic industry Methanol industry (54.4) Types Industrial processes

  18. Industrial processes Plant site selection criteria (54.5) Resource availability Environmental impact Transportation capacities

  19. Suggested Learning and Teaching Activities: Doing decision-making exercises on selecting the location for a chemical plant Abstracted from Chemistry Curriculum and Assessment Guide (Secondary 4 - 6) Prepare for the SBA: non-practical related task

  20. Suggested IT-support materials in industrial chemistry • CAL program (selecting the optimal reaction condition for Haber process) • Animations (electrolysis of brine in membrane cell process) • Mind-map creator (methanol industry) • STSE worksheets (Is it good or bad to build a chemical plant?) • ……
