Alkylation Operations

Topic I: Introduction – Explain what alkylation is. – Identify the major chemical reactions that occur during alkylation. – Identify the main sections of a typical alkylation unit. – Identify the major process variables that are controlled in an alkylation unit. Topic II: Feed Preparation – Identify and describe the feed streams to an alkylation unit. – Describe the equipment and basic operating principles involved in the removal of sulfur from the alkylation feed streams. – Describe the equipment and basic operating principles involved in the removal of water from the alkylation feed streams. – Explain why and how the feed stream is cooled. Topic III: Reaction Equipment – Identify and describe the major components of the reaction section of a typical alkylation unit. – Describe the basic operating principles for the following types of alkylation reactors: jet-type and impeller. Topic IV: Acid Handling – Describe how acid can be handled in a sulfuric acid alkylation unit. – Describe how acid can be handled in a hydrofluoric acid alkylation unit. Topic V: Fractionation – Identify and describe the major components in the fractionation section of a typical alkylation unit. – Identify the product streams produced in the fractionation section of a typical alkylation unit. Topic VI: Process Variables – Identify process variables that are monitored and controlled during alkylation. – Explain why these process variables are important to alkylation. – Describe considerations in responding to a decrease in the isobutane-to-olefin ratio in an alkylation unit. Topic VII: Safety Considerations – Identify safety hazards related to alkylation. – Describe protective gear and safety equipment used to minimize alkylation hazards. – Describe safety procedures that should be followed to minimize alkylation hazards.
