Safety in Process Equipment Design and Operation

Introduction

Safety in Process Design includes a wide range of subjects with many applications in Oil & Gas, Chemical and Process industries, related to hydrocarbons and chemical processing.

This training course provides an overview of important elements of process safety as they are often encountered in today’s industrial practice. The emphasis is on engineering design aspects of Process Safety Management and it will highlight the safeguarding aspects of processing equipment inside the plant.

Techniques for analyzing and mitigating process safety hazards applicable to oil and gas processing will be reviewed. Integration of the concepts required to achieve an optimum approach to Process Safety Engineering is the main goal of this seminar. Exercises and useful examples will be utilized throughout the seminar to emphasise the key learning points.

Upon completion of this training course , the delegates will learn:

• Importance of the concept of “Inherently Safer Design”
• Design principles based on Codes and Standards for safe operation of process equipment
• Selection and sizing of safety valves and pressure relief systems
• Common process hazards analysis methods: HAZOP, LOPA, FMEA
• Detection and prevention methods for fire and explosion accidents
• Plant Equipment Inspection (NDT) and Maintenance Procedures

Objectives

• Comprehensive understanding of different aspects of process design that influence process safety
• Ability to select an “inherently safer design” for the entire process plant operation
• Knowledge on the mechanical structure integrity of process equipment
• Familiarity with hazards associated with process fluids regarding material degradation
• Experience with the Code requirements for sizing relief valves, methodology for determining the relief flows and handling the relief streams.
• Knowledge of how to operate with emergency depressuring systems (EDP) system for prevention of fire and gas explosions
