OIL & GAS TECHNOLOGY

Introduction

The control of processes in today’s oil, gas and chemicals industries requires accurate knowledge of process conditions and this in turn means accurate measurement of those conditions. Without measurement there can be no control and no information as to the state of the process.

A greater understanding of the measuring equipment and the instruments can improve the performance of the operator and this in turn will improve plant performance. Better knowledge of how equipment is selected and how it is constructed and how it works also helps an operator to identify the cause of problems and prevent there

Recurrence, Hence, the economic benefits of properly trained and informed operators can be readily quantified.

The course is designed to provide an overview of industrial measurement and control which includes process measurement (Flow, Level, Pressure and Temperature), transmitter, controller, process control (basic control theory, closed loop, Process dynamic, time constant, process gain, PID Control , practical logic and control system hardware, (UPS, DCS, PLC, and SCADA), alarm and trip system.

The course covers the major components and subsystems of a gas chromatographic system and its accessories, including inlets, columns and detectors. It presents operating principles, set-up procedures, and failure modes for each along with practical examples

The course will cover also the use of best practices in troubleshooting and diagnose of equipment operation problem.

Objective

By the end of the course, participants who are almost all operatorI and OperatorII in production operations, should become able to:

Explain theory behind measurement and control skills

Methodology

Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
