Gas Dehydration (FAC10)
Description
The course covers dehydration of natural gas in some depth. It describes the four main gas dehydration processes of Cooling, Absorption, Adsorption and Membrane dehydration. Absorption processes concentrate on glycol dehydration but also include discussion of enhanced and proprietary processes. Adsorption processes concentrate on molecular sieves but also discuss Silica gels. Membrane dehydration covers the principles as well as typical process arrangements.
The course covers the process design and sizing calculations as well as the equipment within the processes and typical operational issues as well as process design safety matters.
Course Level: Skill
Duration: 2 days

Designed for you, if you are...
- A facilities or process engineer, either a graduate or a more experienced technical professional looking to develop theoretical competence
- A project manager who seeks greater understanding of the process and mechanical design of plants
- An operations engineer looking to deepen your knowledge of the design principles of the plants
- A sub-surface engineer seeking to broaden your technical knowledge
How we build your confidence
The course links theory to application. It reinforces this through real industry problems and examples which are solved by the participants as part of the sessions.The course is highly interactive and participants are encouraged to share their own experiences and problems to the benefit of all.
The benefits from attending
By the end of the course you will have a good understanding of how to select an appropriate gas dehydration method for a field development as well as the basic principles of the process design and how to size the equipment within the process.You will have had hands-on experience of designing a glycol dehydration system and calculating the glycol purity required and the glycol circulation rates as well as the sizing of the main components of the system.
