It is said that it wasn’t very successful; no intention to slander. Could you provide some data? ?

It was very successful; you can look up relevant information to find out.

If you want to know the specifics, the best way is to go and see it in person; then whoever is spreading slander can be identified and dealt with. If the results are good, it means that the technology is improving, so the original poster can rest assured, right?

What is the method without power? Doesn’t the compressed air/oil used to operate programmable valves consume power?

By \"non-powered,\" it is meant that no vacuum pumps or gas compressors are required in this process; as a result, the efficiency of the adsorbent per unit volume is lower. This leads to higher costs for equipment and adsorbents, but long-term operation should still be cost-effective.

UCC Corporation’s decarbonization technology in the United States involves using nitrogen to flush out the carbon dioxide that has not been completely desorbed from the adsorption towers; this results in much lower hydrogen losses. Tenri Company’s processes use hydrogen and nitrogen flushing in this system, resulting in higher gas losses. To be honest, there is no way to determine whether the vacuum process results in less gas loss compared to the flushing process without any data; asking everyone on the 7th floor to take a look isn’t feasible, as there are technical confidentiality agreements in place! I do want to go watch it; who agrees? Based on estimates, if the flushing process is combined with vacuuming, then I think the gas loss should be lower, because the portion that is desorbed through vacuuming does not require hydrogen-nitrogen flushing, right? Floor 6? Maybe I misunderstood? If the gas components of each part are made public, we will be able to see the true situation. Also, regarding the comparison between gas loss and vacuum power consumption, no one has shared their data, which makes the units used unclear; I don’t think this is good. This is my personal opinion; it does not represent the company, nor do I intend to mislead the organizations that use it. As an extra note, Tenri Corporation has a group of outstanding actors. I hope we can all improve together. This post was last edited by CDYANGHAO on 2007-12-23 21:43.]
