REFINERIES – MODULE
1. CRUDE DISTILLATION COLUMN UNIT - CDU
Process Description

Operating procedures consists of start-up, shut-down, normal and emergency procedures. The most critical periods in operation are those of start-up and shut-down. It is then that the hazardous possibility of fires and explosions are greatest.

The hazards normally encountered in start-up and shut-down of units are accidental mixing of air and hydrocarbons and contacting of water with hot oil. Other hazards primarily associated with start-ups are pressure, vacuum, thermal and mechanical shocks. These can result in fires, explosions, destructive pressure surges and other damages to the unit as well as injury to the personnels.

Fires occur when oxygen and fuel vapour or mists are mixed in flammable proportions and come into contact with source of ignition. They may burn out of control or touch off devastating explosion. Pressure surges from unplanned mixing of water and hot oil may cause only minor damage to the equipment.

History shows that most of the serious refinery fires and explosions have occurred on units during start-ups and shut-downs. The units have been designed to avoid most of the hazards encountered. The hazards which cannot be avoided have been identified and the procedures have been set up to minimize the hazards. These steps are outlined and must be diligently followed.

3. FLUIDIZED CATALYTIC CRACKING UNIT - FCCU
Process Description

1.Training Objectives

• This Program is a general program. Although this process appears to be rather simple, there is tremendous amount of knowledge that can be gained about operating various control loops by using the DCS Based Training Simulator System.
• The overall objective of training with this program is to learn about FLUIDIZED CATALYTIC CRACKING UNIT - FCCU. For example, you will learn how to analyze normal operating conditions and how to quickly spot possible difficulties. Most important, you will learn why changes are made, the way or the order in which they are to be accomplished. It is extremely efficient and definitely a safe mode.
• The Program represents a fully instrumented process. You will see on the screen the results of your operating actions in the same way you would see them in the plant. You will log instrument readings and based on these readings, adjust controller set points or take emergency actions. As you learn better procedures, the instruments and your logs will show this too.
• Training with this program is very much like simulation training given to the astronauts and if you relax and put your best effort into learning the program, you will find the experience to be very helpful when you work in the real plant.
