How to Avoid CO2 Accumulation on Ground Floor

Look for options that do not involve venting it at your location. Depending on the purity and the market, you might be able to sell it and offset the cost of collecting it instead of venting.

You might pressurize and refrigerate it and sell the dry ice. There might also be a market for bottled CO2.

...just thought of another idea. Build a large greenhouse and vent your CO2 there or pipe it to a large local existing greenhouse. Greatly increased growth rates may be possible, and a portion of the CO2 will be removed the air.

In a more rational concept you could either move your venting points further away from the building or install more vents at ground level to alleviate the issue.

As far as capture and sell concept CO2 is already mass produced as is so unless you know of a near by consumer that would find getting your CO2 from you to be a cost effective venture along with what it would cost you to purposely capture and process it just vent it off into the massive greenhouse that you have available around you namely nature.

Rumor has it nature has all the plants and other CO2 eating life forms you would ever find in a man made green house and more plus its free to operate and maintain.

The Op was asking for ideas.

These aren't unreasonable ideas. The viability depends a lot on details that have not yet been presented. If you are privy to additional details about the problem in question, let me know where I went astray.

.

Dry ice is fairly simple to make, and in areas where refrigeration is in short supply, the investment may be worth while.

.

If the OP has neighboring businesses that might have industrial use of CO2, there may be a beneficial solution for both.

.

The suggestion of pumping the CO2 to a large commercial greenhouse has the potential to increase growth rates substantially for most plants.

.

The idea, in each case, was to create a benefit that might be leveraged to offset or provide a return on the investment needed for the upgrade.

Declaring outright (with almost no knowledge of the specifics) that the only reasonable action is to move the problem further away, is certainly one way to handle it. It probably meets the definition for standard operating procedure in many places.

I'm merely suggesting there could be some benefits to reserving judgement and refraining from declaring brainstorming ideas are irrational at least until you glean knowledge of contraindicating specifics.

.

and I hope you find them. And may it be quick. I hope you find whoever took a dump in you cornflakes, making you so grumpy this morning. It was wrong and I hope they get what they deserve.

Okay then do you have any working numbers for how much greenhouse floor space is needed for a CO2 absorbing and conversion rate of even only 2 tons per day?

Or for how much energy it takes to clean and condense a ton of CO2 gas into liquid plus the purchase and installation cost related to said equipment?

I have strong suspicions that the numbers for each are going to get real big and realistically cost prohibitive very fast!

Improve the ground floor ventilation....

Dilution may be the most practical way to deal with accumulation.
