Removing Dissolved Gases without using Chemicals
which is a long term environmental contaminant. Formation of Carbon 14 can be prevented by using Liqui-Cel Contactors to remove nitrogen from these feed water systems. Because our membranes are not selective to which gas is removed, all dissolved gases can be removed simultaneously. Membrane Contactors are small clean reliable systems that can be placed virtually anywhere in a building. Contactors have been used for corrosion control in many industries for over 15 years.

Fluitec's ESP - Lubricant Varnish Mitigation
in the fluid. Lubricant varnish has become a significant maintenance problem in many critical applications, such as gas turbines, paper machines and compressors. Turbine oil varnish has been a particularly high profile issue over the last decade. A very small amount of varnish that settles in a susceptible zone, such as a GT ’s fuel control or IGV valve can disable the unit from starting properly, resulting in a fail-to-start condition or in some cases a unit trip. Varnish can negatively impact... (read more)

Anguil Frac Water Reuse Technologies
Over the last ten years, the US energy sector has accelerated the development of its unconventional oil and gas resources through increased use of horizontal drilling and hydraulic fracturing practices. Water is an essential element in the fracturing process. The development of means to recycle and reuse this water is now becoming critical. The volume of water required to fracture a well varies across the country, but it generally ranges from 1 million gallons to 5 million gallons. Operators... (read more)

Liqui-Cel (R) Membrane Contactor Technology Being Evaluated for Dissolved Gas Removal from Water in Many Hydrocarbon Processes
The oil and gas industry has utilized various deaeration technologies for many years to remove dis-solved gases, particularly oxygen, from injection water. Minimizing the environmental impact, improving operating efficiency, avoiding process issues and protecting system components are just a few
Taiwan O2 CO2 Removal Case Study (.pdf)
A semiconductor plant in Taiwan is using Liqui-Cel (R) Membrane Contactors to remove dissolved gas from their ultra pure water (UPW) system. The UPW system is used to purify water used in the chemical mechanical polishing process (CMP) at the fab. The water system was designed and built by United
Bubble Removal from Inks Using SuperPhobic (R) Membrane Contactors (.pdf)
When liquids and gases are brought into contact, mass transfer between the gas and liquid phases will occur. The concentration of gas dissolved in the liquid will continue to increase until equilibrium is reached. When gas concentrations in a liquid reach equilibrium, the liquid is gas

The concentration of gas dissolved in the liquid will continue to increase until equilibrium is reached. Once equilibrium is reached, the concentration of gas in the liquid
Deareation: Degasification of Water Using Novel Membrane Technology (.pdf)
on the surface of finished products or piping material. Also, as the water temperature is increased, dissolved gases can form bubbles that may lead to incomplete wetting of surfaces. The removal of dissolved gases is an important processing step and is routinely accomplished with a vacuum degasification
Performance of Palladium Diffusers for Reliable Purification of Hydrogen

Advanced Oxidation Ditch Performance (.pdf)
; the denitrification rate at 10C is 75% of the rate at 20C. For every gram of nitrate-N that is reduced to nitrogen gas, 2.86 grams of oxygen are saved in terms of CBOD removal. Thus, energy savings of 10 to 20 % can be expected by providing an anoxic zone within the ditch. Denitrification is a zero order
