  1. I thought it was neat too, but then people start telling me to go look at over people's designs, which don't have it. I switched production from Steel over to Iron and both the pump and non pump version have bee producing close to 100% petrol production at 10kg/s. I'm quite surprised about this. In this latest bout of testing, 9 dupes were killed, as they got buried in iron ore that mysteriously appeared from no where and there were not enough digger dupes to free them in time.
  2. It makes more sense now, thank you. A good idea to add a shut off. this setup seems to work nicely, it seems to stop the flow under low heat and doesn't use space stuff. I'm still not sure about where's best to use metals and tempshifts though. it is just a uniformly hot blob of petrol.
  3. I'm not sure what you mean with your first statement. I didn't overlook the shut off. The design has failed on me in previous builds, sometimes the pipe remainder will be just enough to cause a spill over. Most of the time, this is due to the whole system not being hot enough, which can happen when the heat source stops for prolonged periods.
  4. I'm not convinced my explanation is clear as to what I'm trying to do. Most of the oil boiler designs out there, including the video's you mention aren't fool proof, at some random time, a blob of oil will spill from the vent area, polluting the counterflow and cause overpressure damage, this is a pain to deal with in survival. Others are foolproof, but rely on lots of automation. I have built almost all of them in survival games. The device you have shown, does not fully prevent oil spill from entering the counterflow, it uses automation to stop the flow and resumes pumping at a temperature. worst case scenario, this happens. Which will require you to break into it and have your dupes mop the spill. Using the unlimited storage waterfall compressor as part of the conversion chamber, it completely stops ALL oil from spilling into the left hand chamber (shown below) and into the counterflow. I should remind you, that this is what we are actually looking at, all cooling is tertiary to this.
  5. Firstly, I removed the tempshift plates completely and the temperature is down to 115, I later re-added them with 2 spaces in between each plate and the temperature seemed to rise to 117, this increase might be caused by some other factor, like spurious dupe activity. I made another test, not using the thermium pump, however, because it no longer has waterfall compression, it no longer forces the oil to remain in the conversion chamber, I periodically get oil overspill into the counterflow heat exchange, which then blocks and get overpressure damage, which is what I was trying to avoid in the first place. If thermium is available, then using the compressor is the best choice and is 100% failsafe.
  6. I made a oil refinery which works particularly well, converting 10kg/s oil to 10kg/s petrol with just 1 refinery working steel production. It's conversion is always maximum given an initial oil temperature and heat source. I have implemented a cooling solution for this, which works reasonably well, it takes 60c oil and outputs 128c petrol at 10kg/s. Both pipe temperature sensors are set at 405. The hydro sensors The final heat exchange, it has a fault! Fixing it, I think would lose some additional heat from the output petrol. I'm not entirely sure if the tempshifts are doing anything positive. I removed these as well as fixed the heat exchange and the output temperature seems to be stabilized at 115c. The chamber on the right is where the action happens. If you haven't noticed, this uses the waterfall compressor effect, which makes it easy to make, as it can be built in a vacuum and doesn't really require any priming, just pump crude oil straight into the oil pipe and petrol into the refinery, hit go and wait The chamber self primes with oil, which fills the tile and either spills over or blocks itself, either is ok. When the oil reaches critical temperature, it turns into petrol and the waterfall effect starts up, at this time, the hydro sensor can be set to 100kg, releasing lovely petrol into the catch chamber immediately to the left, whereby it is pumped into the contraflow cooler on the far left. Over time, the catch chamber heats up and self regulates at a stable ~405c. One of the side effect advantages of this, is that it provides unlimited storage of your petrol as soon as it's converted, so, if you are feeling extra lazy about wanting petrol, but not bothered about cooling it, you can just leave it sealed up, then after maybe a thousand cycles later, just crack open one of the walls and watch in awe as your entire base fills up with 400c petrol The only caveat is that it uses a Thermium pump. You can get away with using steel for the pump in the contraflow, as petrol reaches here between 180-200c. I would take an educated guess that this would quite easily be possible to build not using space materials. The contraflow can accept input directly from the catch chamber instead of it being pumped in, by just lowering the whole contraflow assembly down 2 or 3 tiles, this would increase it's footspace though. To summarize, This is what I am actually discussing here, an Overpressure Distillation Machine. ALL cooling after this, is a tertiary concern. This requires absolutely NO maintenance or automation, apart from the hydro sensor to activate the pump. Once it's primed, the output is always 100% petrol. When there is not enough heat to convert the oil to petrol, we go into a blocked state, which prevents any further oil from escaping for what ever reason.
  7. It's a shame that we can't recycle dead duplicants into some tasty soilent greens to feed the rest of the colony!
  8. Can we use the liquid storage device as a refinery of oil into petrol, by supplying lots of heat to the main chamber but keep the infinite storage mechanic. I guess that the pump would have a filter on it, any oil gets sent back into the storage. I would suggest something like this, but it doesn't work, as the drip pool turns to petrol and stops it dripping further.
  9. I'll try that, thank you.
  10. I can't seem to get this working anymore, is this still viable?
  11. I'd thoroughly recommend using as much pressure as you can get away with, the higher the better, with an extra large steam area. It will have a massive heat capacity and when you crack that baby open and release the steam, your dupes will be living in a sauna for the years to come!
  12. Are you finding that metal is being sent to the heat exchange stack at above 200c when the volcano is active? I'm going to guess that this is the case. I'd be tempted to place a thermo sensor in the steam room, which only enables the loaders when the temperature is below 200.
  13. I totally disagree with this. The optimist; the glass is just empty and will order a new round immediately, ensuring inebriation. The pessimist; will see the glass full and be left soberly standing at the bar with no drink.
  14. I'm assuming that you like plenty of lag nice and thick with that spaghetti.
  15. As per what Dan mentioned above. Whenever a new battery is added to the main power backbone, I find it best to temporarily set all control battery parameters to 0/1, so that every battery discharges, then when they have all discharged, reset the battery parameters to their respective values. Now, all your generators will switch on at the correct times because all batteries are evenly charged. The downside to this, is that if you keep discharging for too long, your substations will use all their reserve battery power and you may likely get power outages in critical areas, so to prevent this, do it efficiently.
