Can anyone advice regarding theCO2 filters/traps :

1- What is the best type regarding the capacity?

2-Are there any type that can be regenerated?

Thanks....

Hello ahmed_saleh,

1. There are filters which can have a capacity of many e³m³ per day, and some chemicals and processes designed for parts per million. This depends on the feedstock, energy requirements, investment capital, and many other variables.

2. Yes, I can think of at least 4 variations which can be regenerated and even more which are not regenerated.

What kind of capacity, budget, and feedstock are you planning on treating?

Sincerely,

Eugene

Hi Eugene,
Thanks for your response...

Our case is related to protecting some atmospheric storage tanks (capacity of 500 m3 to 2000 m3) form having CO2 inside, due to its effect on the specs of our products by the time.
Thus, our case isn't related to waste management or recovery.

I wonder if you may recommend a proper solution for our case based on your experience.

Thanks..

Hello ahmed_saleh,

A typical method of controlling (or limiting) the amount of CO2 inside a tank with material in it is usually with a Nitrogen cap. Displacing the air or gaseous cap inside the tank is usually performed. To maintain the low level of CO2 in the tank, a slow amount of nitrogen is 'bled' into the tank.

Other options are available but are usually considerably more expensive and require higher levels of operator maintenance.

Does the material that you are storing react with Nitrogen gas?

Thanks Eugene for your response,

Regarding the material that we are storing: it does not react with Nitrogen gas.

Our team had some thoughts about this approach (N2 padding), but it would be difficult to apply for some storage tanks that are located in an isolated areas.

I'm interested to know about the other options even if they are more expensive & require operator maintenance. Please advise.

Hi ahmed_saleh,

The other two options fall into two categories:

1) non-regeneration: this is by injecting atmospheric air which has been passed through a caustic solution, powder, or air purification system filter (similar to N2 generation system)

2) regeration: this is by using an amine system which removes the CO2 and the amine is regenerated (with the CO2 being driven off by either heat or pressure differentials).

The least expensive systems are those which do not regenerate. A caustic system is the least expensive setup for a short term project. A regeneration system is the least expensive for a long-term system. It really depends on what you would like to do 

I hope this helps, and provides you with a few more options.

Sincerely,

Eugene
