PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEARMEMBER OF GROUP AND SUPERVISORS1 PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEARACKNOWLEDGEMENTFirst and foremost, thank you to Allah S.W.T for giving us the strength to finish up this project report. Without Your Willingness we would not be able to complete this project. It wouldbeimpossibletoacknowledgeadequatelyall thepeoplewhohavebeen influential, directly or indirectly in forming this project.We would like to take this opportunity to express our deepest gratitude to our supervisors, EncikMohdImranBinZainuddinandPuanSunitaBinti Jobli whohas given us his constant encouragement constructive advises and his patient in monitoring our progress in this project.Our appreciation and specialthanks goes, Puan Hasnora BintiJafri, Puan Junaidah Binti Jai, Encik Aziz Bin Ishak for supplying the valuable information and guidance for this project.We greatly indebted to Encik Napis Bin Sudin for his cooperation and willingness to be interviewed and for provide us with invaluable information and for his resourcefulness in gathering material.Special thanks owe to Puan Masni Bt Ahmad for her willingness to be interviewed and for the painstaking care she has shown in assisting us throughout the project.We also would like to express our appreciation to the Malaysia Industrial Development Authority (MIDA), Pusat InformasiSirim Berhad, Petronas Resource Center, Jabatan PerangkaanMalaysiaandTiramKimiaSdn.Bhd. (KualaLumpur)fortheirgenerous supply of relevant documents and material needed research.Last but not least to all my lecturers, family, friends and collegues for their encouragement and kind support when we need it most.2 PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEARABSTRACTThe purpose for this MTBE or Methyl tertiary Butyl Ether plant is to produce 300,000 metric tonne/year. MTBE is the simplest and most cost effective oxygenate to produce, transportand deliver to customers. The additive works by changing the oxygenate / fuel ratio so that gasoline burns cleaner, reducing exhaust emissions of carbon monoxide, hydrocarbons, oxides of nitrogen, fine particulates and toxic. Two units will beconsideredwhicharethefluidizations, (Snamprogetti)Unit andtheEtherification Unit. Therawmaterialsusedareisobutane, methanol, andwater asfeedstock. In addition, two types of catalysts are chromia alumina catalyzed compound in Snamprogetti Unit, while sulphonic ion exchanged resin catalyzed is used in the MTBE reactor. A good deal of catalyst has been devoted to improve the activity, selectivity, and the lifetime of the catalysts.IntheDesignProject 2, weemphasizeintheindividual chemical andmechanical designsforselectedequipmentsintheplant. ThechosenequipmentsareCatalytic Cracking Reactor, Multitubular Fixed Bed Reactor, MTBE Distillation Column, Liquid-Liquid Extraction Column and Heat Exchanger.Design Project 2 also includes Process Control, Safety, Economic Evaluation, Process Integration and as well as Waste Treatment, which are considered as group works.3 PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEARCONTENTSTITLEPAGEDECLARATION IICERTIFICATION IIIACKNOWLEDGEMENT VABSTRACT VILIST OF TABLESLIST OF FIGURESLIST OF NOMENCLATURESREPORT 1CHAPTER 1 PROCESS BACKGROUND AND INTRODUCTION1.1 Introduction 11.2 Historical Review of MTBE Production Process 21.2.1 UOP Oleflex Process 31.2.2 Philips Star Process 31.2.3 ABB Lummus Catofin Process 31.2.4 Snmprogetti Yartsingtez FBD Process 4CHAPTER 2 PROCESS SELECTION2.1 Method Consioderation 52.2 Detailed Process Description 72.2.1 Snaprogetti Yarsingtez fbd Process 72.2.2 MTBE Unit 82.2.3 Distillation Column Unit 82.2.4 Liquid-Liquid Extraction Unit 9CHAPTER 3 ECONOMIC SURVEY3.1 Market Survey 103.1.1 World Market 103.2 Asia Market 113.3 Demand 113.4 Production Capacity 144 PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEAR3.5 Supply 143.6 Market Price 153.6.1 Methanol 153.6.2 Isobutane 163.6.3 Catalyst 163.6.4 Conclusion 163.7 Economic Analysis 173.7.1 Break Even Analysis 173.7.2 Data Calculation1 20CHAPTER 4 PLANT LOCATIONS & SITE SELECTION4.1 Plant Location 244.2 General Consideration On the site Selection 244.2.1 Location with Respect To Marketing Area 254.2.2 Raw Material supply 254.2.3 Transport Facilities 254.2.4 Availability Of Labor 254.2.5 Availability Of Utilities 264.2.6 Environmental Impact and Effluent Disposal 264.2.7 Local Community Considerations 264.2.8 Land (Site Consideration) 264.2.9 Political and Strategic Consideration 274.3 Overview on Prospective Locations 274.3.1 Teluk Kalong 284.3.2 Tanjung Langsat 284.3.3 Bintulu 294.4 Conclusion 33CHAPTER 5 ENVIRONMENTAL CONSIDERATION5.1 Introduction 345.2 Stack gas 355.2.1Gas Emission treatment 355.3 Wastewater Treatment 355.3.1 Wastewater characteristic 355.3.1a) Priority pollutants 365.3.1b) Organic 365.3.1c) Inorganic 375.3.1d) pH and Alkalinity 375.3.1e) Temperature 385.3.2 Liquid waste treatment 385.3.2a) Equalization treatment 385.3.2b) Solid waste treatment 395.3.3 Waste Minimization 415 PRODUCTION OF 300,000 METRIC TON OF MTBE PER YEARCHAPTER 6 SAFETY CONSIDERATION6.1 Introduction 426.2 Material Safety Data Sheet 436.2.1 Isobutane 436.2.1.1 Product Information 43Physical & Chemical Properties 436.2.1.2 Immediate Health Effects 446.2.1.3 First Aid Measure 446.2.2 N-Butane 446.2.2.1 Handling and Storage 456.2.3 Methanol 456.2.4 MTBE 466.2.4.1 Physical State and Appearance466.2.4.2 Physical Dangers 466.2.4.3 Chemical Dangers 476.2.4.4 Inhalation Risks 476.2.5 TBA 476.2.5.1 Recognition 486.2.5.2 Evaluation 486.2.5.3 Controls 486.3 Hazard Identification & Emergency Safety & Health Risk 49CHAPTER 7 MASS BALANCE7.1 Snamprogetti -Yarsingtez FBD Unit 517.2 Separator 537.3 Mixer 537.4 MTBE Reactor 547.4.1 1st Reaction in rector 557.4.2 2nd Reaction in reactor 567.4.3 3rd Reaction in reactor 577.4.4 Overall reaction 587.5 Distillation Column 597.6 Liquid Extraction Column 607.7 Distillation Column 617.8 Overall reaction system;
