Glycol System for Dewpoint Control

Dewpoint Control Processing System

Dewpoint Control Processing System

Compass Model No.: LTS and Ethylene Glycol Regeneration System

Application: Natural gas field processing for dewpoint control of natural gas.

Objective: Increase ability of existing hydrocarbon dewpoint control plant and prevent hydrate formation during refrigeration.

Design Challenges: Allow for integration of new equipment into existing plant while minimizing process upset and utility of site equipment.

Compass Solution: Liquid/liquid LTS design (allowed for use of existing LTS for gas/liquid separation) and hydrate suppression injection for new and existing equipment.
