Allisonlastname: /* Space Age Recipes */ add item count to holmium ore for holmium solution

{{languages}}
{{:Infobox:Chemical plant}}
The '''chemical plant''' is a building for processing fluids and solids, usually through chemical processes. Many recipes that either require or provide a fluid other than [[crude oil]] are produced here. The chemical plant has 2 inputs and 2 outputs in fixed positions (their positions can be flipped). Solid items can be both inserted and removed by [[inserters]] from any point (no need to target fluid input/output connections).

When chemical plants are in the process of crafting an item, they will billow out smoke that matches the color of their input ingredients.

== Base Game Recipes ==

The Chemical plant has twelve available recipes in the base game, one of which must be set before it can begin processing.

Aquilo's recipes are able to be selected while on other planets, but because they require liquids that are exclusive to Aquilo and cannot be shipped off-planet, those recipes are effectively locked to the planet.

== Fluid inputs ==
Unlike solid ingredients, which can be inserted anywhere, the fluid ingredients can only be added at the two fixed inputs. Furthermore, recipes which requires two fluid ingredients, will only accept each ingredient on a specific input. When the recipe that requires fluid ingredients is selected, the chemical plant will display icons on the inputs to show which ingredient goes to which input. These fluid inputs can be flipped with {{keybinding|H}} or {{keybinding|V}}.

Heating tower

Allisonlastname: fix units

{{Languages}}
{{:Infobox:Heating tower}}
{{About/Space age}}
The '''heating tower''' burns [[fuel]] to generate heat. Initially unlocked on [[Gleba]]{{SA}}, it is useful for burning off unneeded biological products as well as providing electrical power. It later becomes a vital source of heat against the cold of [[Aquilo]]{{SA}}. The heating tower has 250% efficiency, so it generates 2.5 times the fuel value in heat of any fuel given to it.

The internal heat of heating towers is limited to 1000°C. Like a nuclear reactor, heating towers will continue to burn fuel even if they have reached their maximum heat. The fact that they burn fuel regardless of temperature makes them more useful than a [[boiler]] for destroying unneeded biological materials. Also like a reactor, you can read their heat and fuel status through the [[circuit network]].

The heating tower has a heat capacity of 5 MJ/°C. Thus, they can buffer 2.5GJ of heat energy across their working range of 500°C to 1000°C, and they require 2.43 GJ of energy to warm up from 15°C to 500°C when initially placed. Because of the efficiency however, this means they only need 0.97 GJ of fuel to reach 500°C, which is slightly less than 10 [[rocket fuel]]. More fuel will be needed to bring the connected [[heat pipe]]s and [[heat exchanger]]s up to temperature.

Note that heating towers produce less pollution per unit energy produced than boilers. Boilers produce 3.6 MJ per pollution generated, while heating towers produce 24 MJ per pollution. This coupled with their efficiency makes them a more efficient and clean alternative to boilers on [[Nauvis]].

Rail

Allisonlastname: explain curve radius a bit better

{{Languages}}
{{:Infobox:Rail}}

A '''Rail''' is used for building a [[railway]] track for [[locomotive|trains]]. Unlike [[transport belt]]s, rail tracks can also be curved and placed diagonally. [[Train stop]]s, [[rail signal]]s and [[rail chain signal]]s can be placed on rails to better guide automated trains. [[Gate]]s can also be placed on rails, making them rail gates. In [[Space Age]]{{SA}}, rails can be connected to [[rail ramp]]s{{SA}} and [[rail support]]s{{SA}} to build elevated rails. Elevated rails allow trains to freely pass over obstacles.

The minimum rail turning radius is 13, meaning the smallest possible 180° turn has 26 [[Map_structure#Tile|tile]]s between the centers of opposite rails. However, due to rails being two tiles wide, the actual footprint is 28 tiles wide.

The [[rail planner]] can be used to automatically place rails. See the page for more info.

== Achievements ==
Rails are directly related to the following achievements:

Barrel

Allisonlastname: crafting empty barrels can accept productivity

{{Languages}}
'''Barrels''' can be used to store and transport 50 units of various fluids. Since they are solid objects, they can be used as an alternative to pipes, once [[fluid handling (research)|fluid handling]] is researched. The barrels themselves are reusable once the fluids are drained.

Barrels stack in groups of 10. A single [[cargo wagon]] can hold 400 barrels, which gives a capacity of 20,000 units per cargo wagon – 30,000 fewer units than the capacity of a [[fluid wagon]].

Empty barrels have a rocket capacity{{SA}} of 200. Full barrels, regardless of fluid, have a rocket capacity{{SA}} of 100. As such, a single rocket can carry 5000 units of any fluid which can be barrelled.

== Empty barrels ==
'''Empty barrels''' can be crafted. When barrels are emptied, the (required) [[assembling machine]] will also return an empty barrel.

== Example of use ==
Barrels are useful in situations where pipes are not available or a bad option, such as oil production far away from your main factory, or when transporting fluids to another planet in [[Space Age]]{{SA}}. Barrels can be transported with a [[belt transport system]] or [[railway]], by [[logistic robot]]s, via [[car]] or [[tank]], or in the [[player]]'s inventory. A simple example with [[transport belts]]:

[[File:Crude-oil-barrel-handling-example.png]]

== Notes ==
* Barrel filling and emptying recipes cannot accept [[productivity module]]s or [[quality module]]s.

== History ==
{{History|0.16.8|
* Lowered barrel fluid capacity from 250 to 50. (So cargo wagon with barrels holds 20k and logistic robots are not too strong alternative to carrying fluids.)
* Decreased barrelling crafting time from 1 second to 0.2 seconds.}}

{{history|0.15.0|
* Added automatic barreling support for all fluids.}}
