Curious About CO2 Recapture for Your Brewery? Top Questions We Hear...

How many pounds of CO2 do you foresee being generated based on our current production?

This is a key question. If your goal is CO2 independence in your brewery, how does our equipment get you there? DALUM’S system was designed to capture and process fermentation gas and convert that gas into usable CO2 for your brewery, not just to reduce your CO2 footprint. Our performance does both, we capture and convert the maximum amount of fermentation gas channeled through our system and the reduction of your CO2 footprint is a byproduct of that action. With three sizes of?CO2 Units?compressors, we can tailor a model to your current brewing schedule and collection needs. Our goal is to collect and convert?70-80%?of all fermentation?gas?from the fermenters?gas passed through?in?our system - once O2 levels/Purity are in target range.?With the average barrel of beer in the 6-7% ABV (alcohol by volume) range we can expect that 10 lbs of fermentation gas is produced per barrel. With immediate fermentation containing levels of 02?and?H2O that we cannot process we can assume that we will collect approximately?7.0?- 8.1 lbs per barrel once collection is put online.? We can safely say we will then convert and store 75-80% of this gas.?So, using this example with a 120 Barrel fermenter and 20% headspace we can assume we liquify?700 lbs of gas from the one fermenter?producing 7% ABV beer. We would love to say 100% but that just is not feasible as many factors play into this calculation, purity levels, getting the system online etc.?

?

Can I collect fermentation gas from multiple fermenters at the same time??

With all our systems, yes, you can. We look at the flow of gas coming in to determine the size system that you would need. The feed gas is calculated based on your brewing schedule, ABV/Plato, and fermenter size(s). It is a bit complex but, we will look at peak gas feed at any given time throughout fermentation. You may be a 20k barrel brewery, but may need only a?15kg/h?system.? If the system can collect the flow of gas coming in, we are safe to assume that it will be processed. There are failsafe built into the system to account for vent gas, contaminants etc. that are automatic. The goal is that once the gas is in the system, it stays there.?

??

Can I push the liquid CO2 into an existing bulk storage tank??

With our system, yes, no boosters or additional equipment needed. Our final stage of compression is 600psi so pushing into your existing bulk storage tank is quite easy. At this PSI, any liquid that could not be stored would flash off, and the resulting blow off would be channeled?back to?the CO2 Unit?to?a foam trap or gas collection vessel?to be reprocessed.?

?

How much maintenance is required to stay operational??

If you own a shop vacuum and some basic tools, you can take care of the carbon filtration and the desiccant for the dryers. On average, this should be done every?one to?two years of operation. The advantage of our system is?that?90% of the?many odors, and foreign particulates that make it into the system are removed by our water scrubber which uses a minimal amount of water and only cycles based on the flow of gas through the system.?

?

The compressor itself is very dependable. The oil free non lubricated piston in the compressor has special rings whose lifecycle is dependent on the operation of the system. These could last?6-18 months depending on the brewery and hours of operation. The compressor can be conservatively rebuilt in 4 hours by competent maintenance personnel.?We also offer a core swap out option here in the US. We ship a new/rebuilt compressor, and you send the other back. It is a win for everyone.?(we do not yet have the flexible piping system to offer this but are working on this).

Can I operate and troubleshoot remotely??

One key feature is the ability to control and monitor the system remotely. Not only can you monitor production, but you should also have the ability clear alarms, check production, switch Dewar Tanks. PLCs, like computers may just need a re-boot to get them back online. You should have the confidence and ability to do it from anywhere. Down time means uncollected profits.
