Distillation and Unit Operations, Control and Troubleshooting

Objective:

Understand basic Unit Processes & Unit Operations Learn about Distillation Principles To utilize distillation theory and apply it directly to real and practical problems. Various types of Distillation Column Types and Internals Critical Design Aspects and analysis troubleshooting of distillation processes Learn about the instrumentation and control commonly deployed with the equipment Develop the understanding of distillation problems including thermodynamics and VLE, process design and hardware consideration. Provide the attendees guidelines for the selection of hardware

Description:

Distillation is the most widely used means of separating chemical species in the petroleum and chemical industries and is the first unit operation in an oil refinery. This course covers the key areas of assessing the operation of the internals through to their eventual installation but with the emphasis placed on design, operation, troubleshooting, and control. Various aspects relating to the initial design of column internals are covered, including simulation packages and VLE. Current internals are reviewed including critical design aspects of trays, packing and auxiliary equipment. Distillation column control is an essential ingredient in cost-effective operations, safety, and environmental management.
