LIQUID-Gas Separations
Transcend identifies and eliminates the underlying causes of process problems. Liquid droplets in gas streams are particularly susceptible to shear and shattering into aerosols. Liquid aerosols can affect downstream unit operations like compressors, absorption columns, molecular sieves, cryogenic exchangers and other critical equipment.

Applications for Liquid-Gas Separation Technology
Compressor Lube Oil Carryover Control
Lube oil carryover from compressors represents a persistent operational challenge that can compromise downstream processes, foul equipment and reduce system efficiency. Our advanced separation technologies effectively remove entrained lubricants from compressed gas streams.
- High-efficiency inlet separators with multi-stage separation
- Coalescing filtration systems for submicron droplet removal
- Engineered liquid collection and drainage systems
- Custom-designed separators for specific operating conditions
- Integration with existing compression systems
Amine Gas Treating System Optimization
Optimal operation of amine absorption units requires efficient contact between gas and liquid phases while preventing the accumulation of contaminants that compromise performance. Transcend’s root-cause approach addresses critical fouling mechanisms before they impact operations.
Feed gas containing contaminants like heavy hydrocarbons, corrosion products and particulates create operational issues. These contaminants build up in regeneration columns, recirculate through the system and combine to form "shoe polish"—a hydrocarbon-particulate dispersion that:
- Fouls trays, packing and exchanger surfaces
- Blinds filters and carbon beds
- Stabilizes problematic foams
- Reduces treating capacity
- Increases pressure drop across equipment
Inlet Gas Conditioning
- Advanced inlet separators remove heavy hydrocarbons before system entry
- Proprietary separation technology prevents hydrocarbon washing into amine
- Reduces the root cause of downstream fouling
Activated Carbon Bed Systems
- Properly positioned for maximum hydrocarbon removal effectiveness
- Strategic placement on rich or lean amine streams (5-25% slip stream)
- Custom-engineered vessels with optimized contact time
- Designed to handle both sweet and sour gas applications
Amine Filtration Systems
- High-efficiency particulate removal protects internals and carbon beds
- Removes corrosion products before they combine with hydrocarbons
- Prevents "shoe polish" formation throughout the system
- Extends carbon bed life and effectiveness
Glycol Dehydration System Enhancement
