Unformatted text preview: The objectives : 1. The roles of chemical engineers responsibility while designing the processes and equipments 2. The roles of Inherently Safer Design 3. Review on 1. Materials / chemicals storage refer to TBS course 2. Thermodynamics Phase equilibrium refer to chemical engineering thermodynamics 1 st course The objectives (cont) 4. Design Variables 5. Equipment Sizing (short cut methode of equipment sizing) 6. Material Construction Selection 7. Mechanical design of equipments a. Equipment under internal working pressure load b. Equipment under external working pressure load The objectives (cont.) 8. Vessel stability ( tall tower/vessel stability ) 9. LOPA ( Layer Of (Equipments) Protection analysis The chemical engineers scope of work in industrial fields 1. Process engineering field process engineers 2. Operation engineering field operation engineers 3. Utility / Fasility engineering field fasilities engineers 4. Managerial field plant manager Chemical engineers Responsibilities while designing the process or the equipment 1. Responsible to comply the design intention for example equipment designed should comply the design capacity 2. Responsible to the safety of the equipment while operation / start up and intended shut down fail safe operation philoshopy 3. Responsible to the safety of the environment minimizing/eliminating the consequences of the accident / process failure realization decreasing the likelihood/the frequency of the accident realization using the accurate/suitable of layer of protection (control systems) for the equipment designed Responsible to comply the design intention The steps or squences while designing the equipment / process : 1. Should be familiar / full recognize about what the basic principle / the fundamentals around the equipment 2. Equipment sizing 1. Using the best practices short cut method calculation (using soft wares or empirical equation ertc.) 2. Using the Chemical Engineering Tools to provide the design equations selecting the design variable sizing the equipment 3. Applying the engineering sense , comparing the size of the equipment found/calculated that it is pratically possible / useable The safety of the equipment designed fail safe operation philoshopy Fail ??? fail operation There will be process parameters deviation increasing / decreasing of flow rate, temperature , pressure or composition Safe or unsafe???? Safe operation (while being fail) , mean no accident realization , no equipment damage or minor damage under the acceptable consequences / risk associated The safety of the equipment designed fail safe operation philoshopy What should you need to ensure the fail safe operation philosophy??...
