Why Attend This Training Course?

A course on Hydrocarbon Gas Dehydration using Triathlon Glycol (TEG) focuses on the process of removing water from natural gas using TEG as a dehydrating agent. Hydrocarbon gases, especially natural gas, often contain water vapor that needs to be removed to prevent corrosion, hydrate formation, and operational issues in pipelines and other gas processing equipment.

What Is The Training Course Methodology?

This training course methodology depends on enabling participants to interact and exchange experiences, explore their competencies and achieve their career aspirations, using forward-thinking training arts, such as theoretical lectures and/or open discussion to exchange opinions and experiences, scenarios, innovative thinking brainstorming. Participants will receive an agenda including training material as a reference, in addition to some extra notes and booklets.

What Is The Training Course Curriculum?

Introduction to Gas Dehydration

• Why Dehydration is Necessary

• The importance of removing water vapor in natural gas processing.

• Preventing hydrate formation (which can block pipelines).

• Preventing corrosion in pipelines and equipment.

• Meeting pipeline specifications for water content in gas.

• Types of Gas Dehydration Methods

• Mechanical separation

• Refrigeration

• Absorption (TEG-based dehydration)

• Adsorption (using desiccants like molecular sieves)

Basic Principles of TEG Dehydration

• What is Triathlon Glycol (TEG)?

• Characteristics and properties of TEG.

• Why TEG is effective for gas dehydration (high water absorption capacity, non-volatile nature).

• Process Flow Overview

• Gas enters the dehydration unit (containing TEG).

• TEG absorbs water from the gas.

• Lean TEG (with less water) is circulated through a contactor or absorber tower where it absorbs water from the gas.

• Rich TEG (saturated with water) is then heated in a reboiler to drive off the absorbed water and regenerate TEG for reuse.

Design and Operation of TEG Dehydration Units

• TEG Dehydration Equipment

• Contactors/Absorbers: Where the gas and TEG are brought into contact for absorption.

• Regeneration System: Involves heating rich TEG to remove water and regenerate the glycol.

• Heat Exchangers: To exchange heat between rich and lean glycol and other system components.

• Storage Tanks and Pumps: To store and circulate TEG.

• Process Parameters

• Temperature and pressure requirements for the dehydration process.

• Lean and rich TEG specifications (water content)

• Flow Rate Considerations

  • How to match gas flow with glycol circulation rates to ensure efficient dehydration.

•  TEG Loss and Make-Up: Monitoring and managing glycol losses in the system.

TEG Regeneration and Management

• Reboiler Design: The reboiler heats the rich TEG, allowing water to evaporate and separate.

• TEG Quality Control

• Water content monitoring in both lean and rich TEG.

• How to maintain the proper glycol concentration and manage glycol degradation.

• TEG Degradation: Understanding how glycol degrades over time and factors that contribute to degradation, such as high temperature or contamination by other chemicals.

• Contaminant Removal: Managing contaminants like carbon dioxide, hydrogen sulfide, and other impurities in the TEG.

Environmental and Safety Considerations

• TEG Safety: Handling and storage safety protocols.

• TEG Disposal: Managing waste glycol and any associated environmental concerns.

• TEG in the Environment: Potential impacts of TEG leakage into the environment and safety measures.

Troubleshooting and Optimization

• Common Issues

• Ineffective dehydration (inadequate contact time, improper temperature/pressure).

• High TEG losses or foaming in the reboiler.

• Optimization Strategies

• Techniques for maximizing TEG efficiency.

• How to optimize regeneration processes to improve performance and reduce operating costs.

• Case Studies and Practical Applications

• Real-World Applications

  • Examples of TEG dehydration in different gas processing settings (natural gas, LNG facilities, etc.).

•  Case Studies

  • Learn from actual operational challenges and solutions in TEG dehydration systems.
