3M Liqui-Cel Membrane Contactors have been used for over 10 years and they are clearly proven in the field. In effort to help further educate customers on the benefits of 3M Liqui-Cel Membrane Contactors over conventional forced draft degasifiers for CO2 removal, we have prepared the following technical comparison.
The table below lists the system design requirements that must be thought through at the beginning of the project. You will see that the Liqui-Cel System has fewer restraints.
|Forced Draft||3M Liqui-Cel Contactors|
|Influent water flow rate||Influent water flow rate|
|Influent CO2||Influent CO2|
|Influent water temp.||Influent water temp.|
|Influent water pH||Influent water pH|
|CO2 Outlet||CO2 Outlet|
|Influent suspended solids||Not applicable|
|Physical site limitations||Not applicable|
|Seismic Zone||Not applicable|
|Wind Loading||Not applicable|
|Sump retention||Not applicable|
System Size and Placement
The size of a Liqui-Cel Contactor is comparable to a reverse osmosis (RO) membrane, which makes it possible to design your RO unit and easily accommodate your degassing system in the same system skid/frame. This is impossible when using a forced draft tower. The advantages here are saving space and lowering installation costs. Additionally, no special foundation is needed for your Liqui-Cel System. These points are very important to consider when comparing a Liqui-Cel system to a forced draft tower because the foundation, support structure, and installation of a tower can be a big expense.
