The Flying Fox Posted February 16, 2018 Share Posted February 16, 2018 Much tinkering has brought me to this design of a petroleum to natural gas generator and works pretty dang well! The liquid valve is set to 500 G/s which is plenty of natural gas to work with and the machine seems to run the best around this setting. Setting it less means less natural gas builds up in the upper part of each step which is actually bad as less heat gets trapped within the machine and the petroleum doesn't pick up enough heat to get near boiling at the bottom. Setting it much higher means that very little natural gas escapes. (Or none at all) The falling petroleum both semi-blocks and helps pump the natural gas steadily upwards to the top of the machine. Basically, it works wonderfully when there's +5 KG of natural gas right where the top of each wire bridge is. The temperature of the petroleum works best when it's 70+ C. In this setup, I set it the same as the oil refinery's output temperature, however, because the conversion of petroleum to natural gas creates more energy then it takes in, you'll still have to actively cool the output natural gas as it comes out around 150+ C. Still, the whole thing can run for a long time on a tiny amount of magma once it's up to speed which couldn't take too long as the mass of the radiator is small. Those wire bridges don't really add up to much! Use iron ore! The left hydro switch is set to 'below' 10 KG and just turns the shut-off valves on the top on and off if there's a build up of petroleum at the bottom. The right hydro switch is set to 'above' 2KG and just operates the doors to control the flow of heat from that small box that had magma in it. As for the automation, the buffer gate is set for 4 seconds, the middle filter gate is 3 seconds, and the right filter gate is set for 30 seconds. (It's plugged into the second door) Link to comment https://forums.kleientertainment.com/forums/topic/87662-super-efficient-petroleum-to-natural-gas-generator/ Share on other sites More sharing options...
Lifegrow Posted February 16, 2018 Share Posted February 16, 2018 You're using a heat deletion bug here approximately 25 times Might I ask what temperature your oil enters the system at and how quickly it changes from each step? Also, have you a thermal shot? Great idea, but sadly for me I think it's based entirely on surface tension temp-shift issues. *Edit - re-read your post - and rephrased* Link to comment https://forums.kleientertainment.com/forums/topic/87662-super-efficient-petroleum-to-natural-gas-generator/#findComment-1004756 Share on other sites More sharing options...

Great idea, but sadly for me I think it's based entirely on surface tension temp-shift issues. *Edit - re-read your post - and rephrased* Honestly, I thought that might be the case when I made the machine, however that doesn't really appear to be the case at all. Drip-cooling would prevent the petroleum from heating up, but that isn't the case for sure. Also, the natural gas is coming out literally twice as hot as the incoming petroleum. If drip-cooling was truly an issue here, then the whole thing wouldn't work as well as it does. The input temp of the petroleum, by the way, is 74.9, the same as the output of the oil refinery. And here's a thermal shot, although it's basically all red. And here, instead of me trying to describe the thermal gradient through the radiator, just have the save. It's easier that way!

Saturnus Posted February 16, 2018 Share Posted February 16, 2018 There's a fairly easy way to check if there's heat deletion bug involved. Is the resulting temperatures different if it was a straight channel? I made something very similar recently. The principle still works the same you just have to change the heat source to a small magma chamber.

Roboson Posted February 16, 2018 Share Posted February 16, 2018 They're heating someone thing up. Using heat deletion while trying to heat something would be counter-intuitive. I'm not sure it would even work in a straight line, not due to a bug, but because of physics.

It'll work in a straight line. I've made something similar before as you can see in the link or in many of my old high efficiency distiller designs.

Roboson Posted February 16, 2018 Share Posted February 16, 2018 Im sorry, which link? It was my understanding that this worked so well because it's heating each little pocket individually instead of one long puddle. That wouldn't be the case in a flat puddle.

Using heat deletion while trying to heat something would be counter-intuitive. I'm not sure it would even work in a straight line, not due to a bug, but because of physics. Something like his can work in a straight line, but not as well. One of my original prototypes was something more like Saturnus made in the past, as he mentioned. However, a straight line design has two issues this one doesn't. A straight line of petroleum acts more like a beam of tile thermally and you don't really get a nice thermal gradient of high and low. The temperature just tries to average itself instead. By having steps it breaks up the petroleum more into sections to try and prevent heat from moving up. Also, in a straight design, the petroleum will bunch up where the vent is with plus 10+ KGs building up there. The steps prevent the petroleum from doing that. Edit: Exactly as Roboson said. A flat puddle just spreads it's heat around the whole thing and actively prevents heating the petroleum to neat boiling at the heating end.

Saturnus Posted February 16, 2018 Share Posted February 16, 2018 This was the old version of my cooker linked above. Achieved the exact same thing as yours. Just much more compact and much more efficient using crude oil from slicksters as the input. Note how only 7 tiles long tombstone heat exchanger can heat the crude oil from about 40C to to about 360C. That's why I think there's a lot of unnecessary heat deletion going on so you're having to make it bigger, much too big to be practical, to compensate. 11 minutes ago, Roboson said: Im sorry, which link?

The Flying Fox Posted February 16, 2018 Author Share Posted February 16, 2018 Seeing as my design hits about the same temperatures in the first 11 wire bridges, I'd say mine works very similar as yours. So, it's not bugged then. And, of course there's going to be a much longer radiator in my setup because I'm trying to push it far closer to boiling temperature then yours did. A whole 180C degree difference and, as anyone whom knows about thermal exchangers, or any thermal exchange for that matter, less heat moves when the temperature delta drops. So the last 6 wire bridges only move the petroleum up another 40 degrees or so simply because the petroleum is already so hot compared to the natural gas at that point.

Saturnus Posted February 16, 2018 Share Posted February 16, 2018 Mine reached boiling temperatures in the drop off the end. It literally vapourizes as it hits the hot plate. Check the save file and just remove the tepidizer for a magma heater. It'll use next to no magma although I can't guarantee it'll be less heat energy extracted than yours, it'll be very close.
