Technical Comparison: CO2 Removal — Comparison of Liqui-Cel® Membrane Contactors to Forced Draft Degasifiers
April 5, 2004
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 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.
Design Requirements
| Forced Draft | 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.
