Compact Water Handling
Getting the water quality and water chemistry right is fundamental to ensuring a decent rate of return on water-based enhanced oil recovery investments.

Boiler Feed Water Degasification Using Membrane Contactors - New Methods for Optimizing Performance
Liqui-Cel® Contactors have been used to remove dissolved oxygen in boiler feed water systems for years.  This paper discusses how Membrane Contactors can be optimized as boiler feed water deaerators for oxygen removal from water as well as carbon dioxide removal from water. The report also highlights advantages of Liqui-Cel systems over conventional deaerators and forced draft degasifiers.

Membrane Contactors: An Introduction To The Technology
This paper provides a good overview to Membrane Contactor technology. Principles of Membrane Contactor Operation and mass transfer principles are discussed.

Using Gas Transfer Membrane to Deaerate Cold Boiler Feed Water Reduces Steam Duty and Operating Costs
This case study gives an account of how Gas Transfer Membranes (GTM), enabled a refinery to deaerate cold boiler feed water to replace the steam duty, associated with traditional steam deaeration, with waste heat. Significant energy cost savings were realized resulting in a very quick payback for the refinery. The article is courtesy of PTQ and was originally printed in the Q1 2012 issue.

Using Membrane Contactors For CO2 Removal To Extend Resin Bed Life
This case study discusses operating savings and efficiency improvements at City Public Service in San Antonio, Texas.  They chose Liqui-Cel Contactors over a forced draft deaerator for CO2 removal from water at their plant to extand resin bed life, lower operating costs, and do away with chemical addition.

UltraPure Water: Systems for Microelectronics
This article, discusses the use of Liqui-Cel® Membrane Contactors as the degassing and oxygen removal technology used in new semiconductor plants instead of older technologies such as vacuum towers.

Osmotic Distillation using Liqui-Cel® Membrane Contactors
This paper discusses the benefits of using Liqui-Cel® Contactors for juice concentration by osmotic distillation.

VLSI chooses Liqui-Cel Contactors over Conventional Vacuum Tower for Deaeration
This paper describes the process and technology that VLSI evaluated for their San Antonio Texas Plant. Liqui-Cel® Contactors were chosen over vacuum deaeration for oxygen removal of < 1ppb.

Degasification of Boiler Feed Water with Liqui-Cel® Membrane Contactors
This paper discusses how Liqui-Cel® Degasifiers can be optimized as boiler feed water deaerators for oxygen removal from water and carbon dioxide removal from water. Advantages of Liqui-Cel® systems over conventional deaerators and forced draft degasifiers are also highlighted.

Mansfield Brewery Uses Liqui-Cel® Membrane Contactors to Nitrogenate Beer
Nitrogen is added to beer with Liqui-Cel® Contactors to control CO2 content and produce a smooth keg beer that mimics cask–conditioned beer while maintaining the ‘head’ characteristics of a keg beer.

Membranes for Oxygen Removal in 300mm Semiconductor Processing
