Kermack Posted August 25, 2019 Share Posted August 25, 2019 So I found a hydrogen vent on a new game and the gas temps are ~35C, but the description says 500C. Think this is a bug?

SharraShimada Posted August 25, 2019 Share Posted August 25, 2019 Nope, no bug. Temperature will rise with pressure. When the room is full, and you start pumping it out, the geyser can pump in hydrogen again. And this is really hot stuff. A hydrogen vent can easy melt down a gold pump.

Promethien Posted August 25, 2019 Share Posted August 25, 2019 How long has it been erupting? All the cool material around it will disperse the heat for a while but not for long considering hydrogen has a decent SHC and 500c is a lot.

Kermack Posted August 25, 2019 Author Share Posted August 25, 2019 Let me clarify. The vent was buried completely and I made a water lock and dug a vacuum around it. The first eruptions were very low temps. I only noticed the temps were supposed to be 500C after I started harvesting the gas. As of editing this it seems the temperatures are now ramping up. I was able to run for several cycles and fill up 2 gas tanks before the temps began to increase. They are emitting at around 100C presently.

avc15 Posted August 25, 2019 Share Posted August 25, 2019 it's because the vent doesn't produce much mass, the H2 will transfer heat to all the mass surrounding it leeching all the temp out, at first. It will eventually overheat your equipment unless you actively provide cooling.

Eventually, your water lock (did you use water) will evaporate. If you used crude, you may eventually get petro. If you used petro, then you'll maintain the lock, but you will bleed heat out of the room.

Miravlix Posted August 25, 2019 Share Posted August 25, 2019 Water lock isn't good enough it's still mass the H can transfer the heat to, you need a vacuum lock and perfect insulation, to instantly see the 500C output. I don't cool geysers, I create a insulated cube for my dupes to live in, so I don't really care if the asteroid is heated a little after 1000 cycles and I just can't see myself playing 5000 or more cycles, so I will never play long enough that the asteroid run out of mass to "hide" the heat in. Only if you do vacuum builds does the game truly require dealing perfectly with heat.

Yoma_Nosme Posted August 25, 2019 Share Posted August 25, 2019 Anyhow. Leave 3-4 space between the vent and the pump. Make radiant pipes with ph2o inside. Let the ph2o cool and automate valve with temp sensor to refresh the cycled liquid. Works very well for me with hydrogen vents. I usually stick a door compressor on the other side of the room too just because... But in case of emergency (haven't happened but), it can vacuum the room and acts as the hydrogen storage in the meantime Link to comment https://forums.kleientertainment.com/forums/topic/110965-cool-hydrogen-vent/#findComment-1249785 Share on other sites More sharing options...
Sasza22 Posted August 25, 2019 Share Posted August 25, 2019 Hydrogen has really good thermac conductivity and realtively small heat capacity. This along with the low mass of the hydrogen produced makes it cool down pretty much instantly.

It's literally third for highest specific heat of gasses, after only steam and super coolant (when gaseous). And seeing as the other two have a relatively high temperature floor for being in a gaseous state, it's definitely the most flexible.

The heat capacity of hydrogen at the expected flow rates (≤ 1 kg/s) is minimal when compared to a water pipe at 10 kg/s, or to a chamber that probably has already at least 40 kg of reasonably-cool hydrogen left in it.

Right, but that's literally every gas compared to basically all liquids. Having 1/10th the mass per pipe segment will always kill your total heat capacity. It also costs way more energy to pump gasses per volume for the same reason (4800W vs 240W).

I legit thought it had a low heat capacity for how easy it was to heat and cool it but i guess it was just the conductivity and the low mass. Actually a large heat capacity makes sense for it being used so often to transfer heat.

Lilscratchy Posted November 1, 2019 Share Posted November 1, 2019 I don't know if people are still wondering about methods for cooliglng hydrogen from vents ut I've gotten myself a pretty effective system for my needs. For the purpose of clarity the Gass coming out of the vent I used this on comes out at between 100c and 150c So I encase the vent in insulated tiles leaving one long open 'corridor' for the heated hydrogen to pass through. Near the vent I have three automated airlocks setup. They are set up to close with the middle one left open when Gass pressure on the side of the Gass I'm pumping out reaches near max (5kg) This prevents further heat transferring over to the gas intended for piping from the vent as it erupts. Since the little bit of Gass stuck in the middle sucks at transferring heat. There's a an automated airlock located on top of the corridor which is set to open when the Gass reaches a temperature I see fit for pumping into my base,I have it set at below 30C. When it opens Gass can then flow into the gas pump which stores the Gass to be used for hydrogen generators. It uses a buffer gate set to 10 seconds because my base cooling easily allows for some hotter gasses to be pumped in to heat up my equipment. This has to do with the fact that as the pump pumps gasses out, pressure lowers and the 3 automated airlocks near the vent open again, allowing hotter gas to flow in and possibly heating up Gass I'm pumping out, but I do want to ensure taking in a proper amount of Gass for use. But I digress. The bottom side of the corridor has a row of metal tiles in it, with directly under it 6 wheezeworts in hydrogen which for me provide plenty cooling to cool the Gass down to usable temperatures over a short period of time. Hope this useful to anyone, might upload a picture of my setup later if anyone wants to see Link to comment https://forums.kleientertainment.com/forums/topic/110965-cool-hydrogen-vent/#findComment-1279433 Share on other sites More sharing options...
