Volatiles or 'H2' is a combustible gas in the presence of Oxygen and the breathing gas of the Zrilian species. The main source of Volatiles on most planets is in the form of Ice (Volatiles) that can be mined on the surface. Volatiles will autoignite at 300 Celcius or above in the presence of Oxygen, and autoignite at 50 Celcius or above in the presence of Nitrous Oxide.
Denoted with the name Volatile, it is a homogenous compound made up of Hydrogen, Chlorine and Hydrocarbons. This means that it is poisonous due to the Chlorine, but also combustible due to the Hydrogen and Methane portions and can be turned into Water with Oxygen in a H2 Combustor that has a self-contained catalyst which helps free the Hydrogen atoms.
Possible compound: CH3Cl (Chloromethane)
Volatiles are an extremely reactive, complex organic molecule, which can be used in conjunction with Oxygen as a combustible fuel. It is refined from Ice (Volatiles).
Due to obscure and largely forgotten ODA regulations, volatiles are sometimes labelled 'H2' by various items of technology. however, though they are similar to Hydrogen, they're not 'actually' Hydrogen. Volatiles will not produce water when produced without a catalyst (See the H2 Combustor). Alone, they create pollutants and Carbon Dioxide when burned in the following ratio:
Different ratios of Volatiles and Oxygen will produce different temperatures and pressures during combustion. Combustion will create a large amount of Heat, pressure, and Carbon Dioxide. This reaction is useful inside a Furnace for smelting ores and creating alloys, but can be catastrophic when inside a Canister or a room. Currently as of version v0.1.1089.5513, it is labeled in the atmospheric analyzer as H2, but it is not Hydrogen.. When burned, it produces heat, Pollutants, and Carbon Dioxide in the following reaction:
Enthalpy of volatiles is 286000 Joules, this is per amount of Moles of matter.
Since both reactions results in same amount of heat, but the one with Nitrous Oxide results with less moles, it produces much more heat per amount of matter (2.25 times more heat energy per mole of reaction products). Also, Nitrogen has lower heat capacity than pollutant, which results in even higher temperature.
This reaction is inconsistent with volatiles being simple hydrocarbons (too much CO2 is produced), but it may be consistent with more complex organic molecules. If either volatiles or oxidizer is below 0.3mmoles, it reacts completely without any residue. The reaction rate by default (for example: in atmosphere) depends on temperature as clamp01(1 / (0.002 * (TC + 273.0)1.6 + 0.05) / 5 for oxygen as an oxidizer, and clamp01(1 / (0.0025 * (TC + 273.0)1.01 + 0.05) / 5 for nitrous oxide. Thus, the maximum default reaction rate is 0.2 and is valid at temperatures below 211C when without nitrous oxide and 107C when enough nitrous oxide is present (>~5%). After that reaction rate decreases logarithmically. At temperatures above 460C, nitrous enriched fuel combusts faster (at approx. 2x rate) than oxygen only. At higher temperatures, the difference is even greater, thus making the reaction more efficient and violent. Some devices (like H2 Combustor or Gas Fuel Generator) increases rate of reaction (to 0.9 i.e. 90% in both cases).
If a combusting gas mix contains Volatiles, NOS, and O2, they all will react proportionally at same rate, according to aforementioned reactions (i.e. at 90% reaction rate and ideally balanced mix, each component will decrease by 90% from it's original amount). When mix is unbalanced and have either excess of volatiles or oxidizers, then proportions decrease accordingly, i.e. with excess of volatiles, only the amount of volatiles corresponding to amount of oxidizers (2 per Oxygen, 1 per Nitrous Oxide) will decrease proportionally; with excess of oxidizers, similarly, only the amount of oxidizers corresponding to the amount of volatiles is decreased at reaction rate, i.e. oxygen reacts at half the rate of nitrous oxide.
Volatiles have a specific heat of 20.4 Joule / mol.
- The Specific heat of 20 Joule / mol is in-between the specific heat of Hydrogen and Methane.
- The actual Autoignition temperature of Chloromethane in Oxygen is 625 °C (1,157 °F; 898 K), the game grossly underestimated the iginition temperature by about 11 times.
You can collect Hydrogen from the following sources:
|Ice (Volatiles)||22 mol|
|Ore (Cobalt)||1 mol|
Can be also obtainable by trading.
- Seems that a concentration of H2 greater than 6% in an atmosphere it is lethal to plants, keep attention on that designing a greenhouse, because Advanced Composter will release H2 during the process.
