== Description == 
<blockquote><q>Volatiles is a combustible fuel. It is refined from [[Ice (Volatiles)]]</q><br>
'''- Stationpedia'''</blockquote>

'''Volatiles''' or '''H<sub>2</sub>''' 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]].

=== Composition ===
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 [[Kit (Atmospherics) H2 Combustor|H2 Combustor]] that has a self-contained catalyst which helps free the Hydrogen atoms.

Possible compound: CH<sub>3</sub>Cl (Chloromethane)


== Usage == 
''See also: [[Fuel]]''

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 H<sub>2</sub>, but it is not Hydrogen.<ref>Stationeer's Discord https://discordapp.com/channels/276525882049429515/392785541411635201/393216103284998144</ref>. When burned, it produces heat, [[Pollutant]]s, and [[Carbon Dioxide]] in the following reaction:

2 Volatiles + 1 O<sub>2</sub> → 3 [[Pollutant|X]] + 6 [[Carbon Dioxide|CO<sub>2</sub>]] + 2×Enthalpy<sub>volatiles</sub> heat energy

1 Volatiles + 1 [[Nitrous Oxide|N<sub>2</sub>O]] → 2 [[Nitrogen|N<sub>2</sub>]] + 2 [[Carbon Dioxide|CO<sub>2</sub>]] + 2×Enthalpy<sub>volatiles</sub><ref>Cows are evil youtube video https://youtu.be/-nELRhGK1_A?t=890</ref> heat energy

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 CO<sub>2</sub> 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 * (T<sub>C</sub> + 273.0)<sup>1.6</sup> + 0.05) / 5 for oxygen as an oxidizer, and clamp01(1 / (0.0025 * (T<sub>C</sub> + 273.0)<sup>1.01</sup> + 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|H2 Combustor]] or [[Kit_(Gas_Fuel_Generator)|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.

===Notes===
* 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.
* Seems that a concentration of Volatiles greater than 6% in an atmosphere it is lethal to plants, keep attention on that designing a greenhouse, because [[Kit (Advanced Composter)|Advanced Composter]] will release Volatiles during the process.
* Enthalpy of Hydrogen (H<sub>2</sub>) combustion is precisely 286 kJ/mol

==Sources==

== Description ==
There are two types of fuel, solid fuel and gas mixtures.
===Solid fuel===
There are currently only solid fuel available in the game [[Special:MyLanguage/Ore (Coal)|Coal]], and [[Charcoal|Charcoal]]. Both can be used to fuel the [[Solid Fuel Generator]].
When burning coal and charcoal they produce the following gases.

|}

===Gas Fuel===
In order to use gases for fuel you need a combustible gas combined with an oxidizer. The only flammable gas in the game is [[Volatiles]] (labeled as H<sub>2</sub>), the two oxygen sources are [[Oxygen]] (2:1 mix simply called fuel) and [[Nitrous Oxide]] (1:1 mix called superfuel or NOS).

When using liquid fuel some heat energy produced will be spent to evaporate liquid fuel components.

== Using Fuels ==

=== Fuel Combustion ===
Autoignition Temperature: 300℃<br>
2 Volatiles + 1 O<sub>2</sub> -> 3 Pollutant + 6 CO<sub>2</sub> + 572kJ

=== Superfuel Combustion ===
Autoignition Temperature: 50℃<br>
1 Volatiles + 1 N<sub>2</sub>O -> 2 N<sub>2</sub> + 2 CO<sub>2</sub> + 572kJ

=== Fuel Combustion Using a H2 Combustor ===
2 Volatiles + 1 O<sub>2</sub> -> 2 H<sub>2</sub>O + 429kJ

Note that staying below autoignition temperature means condensation for Nitrous Oxide at more than about 1MPa pressure, making it hard to store the fuel mix in large quantities without liquid management. While this reaction releases the same amount of energy as the classic fuel combustion above, it does so using half the volatiles and heating waste gases with less thermal mass resulting in higher temperatures.

== Collecting gases == 
Gases can be collected from a number for sources. On some planets Oxygen may be collected directly from the atmosphere. This can be accomplished with an [[Active_Vent|active vent]], some [[Pipes|pipe]] and a [[Gas Tank Storage|gas tank storage]]. On other planets the oxygen will have to be filtered out from the other gases. A [[Filtration|filtration unit]] and a [[filter]] will be needed for this. Some planets, however, have no atmosphere at all. In these cases the gases needed can be obtained by melting or crushing ices. This is by far the most common source for gases early in the game.
A basic [[Ice Crusher]] setup will provide most of your gas collection and mixing needs.
===Basic Ice Crusher Setup===
====Parts required====
* 1 x [[Ice Crusher]]
* 5 x [[Pipes]]
* 1 x [[Pipe_Volume_Pump|Volume Pump]]
* 1 x [[Pressure Regulator]]
Optional
* 1 x [[Active Vent]]
With this setup you can collect gases from ices to mix later. You can also pre-mix the gases by adding Volatile ice and Oxite at a 2:1 ratio. You can then load the pre-mixed fuel in canisters in pre-measured amounts using the pressure regulator.
====Setup====
[[File:ICE_CRUSHER.png|thumb|Combination Ice Crusher, Gas collection, and Gas measuring station, Front View (Caution: Be sure to turn of the pressure regulator, and pump al the gas out of the crusher when mixing gases)]]
# Place the ice crusher
# Place a pipe facing to the right
# Place a volume pump
# Place a pipe tee facing left,right, and down.
# Place a canister storage below the tee
# Place a regulator to the right of the tee
# Place a tee facing left,right, and down, Or an elbow facing left and down.
# Place a second canister storage below the tee or elbow.
# (Optional) Place an active vent to the right of the last canister storage.
====Usage====
====Fuel mixing====
# Place Volatile Ice and Oxites in the ice crusher at a 2:1 ratio. <br> &ensp; &emsp;'''*''' You can safely fit 8 Volatile to 4 Oxites in a canister. A Ratio of 10:5 will over fill a single canister <br> &ensp;&emsp;'''**''' Be sure to pump all the gases out of the crusher into a single canister, otherwise the mixture will fluxuate as the grinder processes and outs ices. <br> &ensp;&emsp;'''***''' Also be sure to turn off your regulator while you are collecting gases.<br>
# Pump the gases to your storage containers. <br>
# Set the regulator to the approximate pressure required to load the amount of fuel you need into the canister. <br>&ensp;&emsp;'''*''' You can check the exact amount in the canister using the tablet and the gas analyzer
====Refiling oxygen tanks====
# Purge the pipe network of any spurious gases from previous operations.
# Crush Oxites in the the ice crusher
# Pump the Oxites into a canister. <br>&ensp;&emsp;'''*'''A canister can hold approximately 12 Oxites.<br>&ensp;&emsp;'''*'''You will need to use a nitrogen filter in additon to your regular CO2 filter when breathing crushed Oxites.
====Emptying Canisters====
# Place any canisters you want to empty into the far left canister storage
# Set the active vent to "outward" and turn it on.
====Collecting Atmospheric Gases====
# Place any canisters you want to fill in the far left slot.
# Set the active vent to "Inwards" and turn it on. <br>&ensp;&emsp;'''*'''Be aware that the canister will fill very quickly, be careful not to over-pressurize the canister.

== Mixing Fuel == 
You can easily mix fuel by adding O<sub>2</sub> and H<sub>2</sub> to a pipe network in order to put it into canisters or pump into a furnace.

H<sub>2</sub> can be attained by melting the [[Ice (Volatiles)]] that can be found in some worlds while being part of the atmosphere of [[Worlds#Vulcan|Vulcan]]. O<sub>2</sub> can be attained by melting the [[Ice (Oxite)]] or again from some atmospheres. N<sub>2</sub>O is part of [[Ice (Nitrice)]] or can be created by the [[Nitrolyzer]].

Depending on how exact the proportions of your gas mixture are you will end up with different end temperatures and pressures after ignition.

===Basic Canister Mixing Setup=== 
====Parts required====
* 2 x [[Portables Connector]]
* 2 x [[Portable Gas Tank]]
* 1 x [[Pipe Gas Mixer]]
* 1 x [[Gas Tank Storage]]
* ''n'' x [[Pipes]]
* ''n'' x [[Cables]]
* ''n'' x [[Gas Canister]]

====Setup==== 
# Place both Portable Connectors
# Connect both Portable Connectors to the the inputs of the Pipe Gas Mixer
# Connect the Pipe Gas Mixer output to the Gas Tank Storage input
# Connect the Pipe Gas Mixer power input to power source.

====Use==== 
# Put first Portable Gas Tank or scrubber filled with O<sub>2</sub> on one Portables Connector.
# Put second Portable Gas Tank or scrubber filled with H<sub>2</sub>/volatile on the other Portables Connector.
# Use a wrench to connect both Portable Gas Tanks to their places.
# Optional: for a perfect fuel mix, ensure the temperatures of both gases are exactly the same.
# Set the Pipe Gas Mixer to desired combination (34% O<sub>2</sub> + 66% H<sub>2</sub>) Note: as the combination is a floating point number, you can also enter 0.333... or 0.666... with a labeler to get a more precise mix.
# Turn on Pipe Gas Mixer
# Place an empty Gas Canister in Gas Tank Storage.

Rocket Engines give you their max output in kN with this you can calculate what they can reasonably carry into orbit depending on the planet or moon you are on. Force = Mass * Acceleration. Acceleration is equal to the planet's gravity, Mass is given in kg per part of the rocket, and Force is kN. If your thrust force listed below is less than the weight of the rocket in kN then you will not even take off. It is better to have a thrust much higher than the weight of the rocket or else you risk running out of fuel on launch and on landing.

Liquid propellants bring greater efficiencies. Using Nitrous Oxide as oxidizer provides excessive thrust values. Keep in mind that N2O fuel mix is 1.9375 times heavier while thrust boost is around 1.5-1.7. Engine efficiency determines "bonus" thrust multiplier, meaning engine with higher efficiency will give more thrust consuming same amount of fuel. Thus using liquid engines is more favorable if one can cool fuel down, moreover Pressure Fed Engines consume fuel inversely proportional to its temperature. On the other hand if [[Volatiles]] and [[Oxygen]] are in excess (e.g. farm on [[Vulcan]]) is may be much easier to opt for Pressure Fed Gas Engine. It will provide ~40kN at 20°C.

== Description == 
The pumped gas rocket engine uses a 2:1 mix of [[Volatiles]] to [[Oxygen]]. It has a maximum thrust of 16.2kN and contributes 500kg to the overall weight of the rocket.
To travel to mars orbit it is recommended the rocket weigh less than 8000kg.

[[Category:Rocketry]]

Rocket Engines give you their max output in kN with this you can calculate what they can reasonably carry into orbit depending on the planet or moon you are on. Force = Mass * Acceleration. Acceleration is equal to the planet's gravity, Mass is given in kg per part of the rocket, and Force is kN. If your thrust force listed below is less than the weight of the rocket in kN then you will not even take off. It is better to have a thrust much higher than the weight of the rocket or else you risk running out of fuel on launch and on landing.

Liquid propellants bring greater efficiencies. Using Nitrous Oxide as oxidizer provides excessive thrust values. Keep in mind that N2O fuel mix is 1.9375 times heavier while thrust boost is around 1.5-1.7. Engine efficiency determines "bonus" thrust multiplier, meaning engine with higher efficiency will give more thrust consuming same amount of fuel. Thus using liquid engines is more favorable if one can cool fuel down, moreover Pressure Fed Engines consume fuel inversely proportional to its temperature. On the other hand if [[Volatiles]] and [[Oxygen]] are in excess (e.g. farm on [[Vulcan]]) is may be much easier to opt for Pressure Fed Gas Engine. It will provide ~40kN at 20°C.
