Description
Used to separate gases from one pipe network into another using filters. Can filter up to two (2) gases at once. Guide (Filtration) provides additional information regarding the function, construction, and operation of a Filtration unit.
Usage
Once you have placed the Filtration Unit in your desired location, there are 3 separate connections that will need to be made:
- Input - Starting gas network that you want to filter from
- Output - Filtered gas
- Waste - Remaining unfiltered gas from the input
Place the appropriate filter(s) in the Filtration unit for the particular gas that your want to filter. Up to two filters can be placed into a filtration unit. If these are different types of filters, both types of gas will be filtered simultaneously. Placing two of the same type of filter in the unit does not increase filtration speed, it just provides redundancy for when one of the filters runs out.
Be aware that the filtration unit unrealistically has an infinitely powerful pump integrated into its output port. That means as long as it is turned on and there is gas to filter out from the input, it will pump that filtered out gas into the output pipe network (no matter how high the pressure in that output pipe network already is!). So eventually that pipe network will burst (around 60 MPa) unless you provide some sort of pop-off valve (e.g. a combination of a back-pressure regulator and a passive vent), use a pipe analyzer and some logic to turn the filtration unit off when a certain amount of pressure is exceeded in the output pipe network, or use the onboard IC10 and a data connection to the output (tank or pipe analyzer) to disable the unit when it reaches a certain threshold. Note that on-board IC10 chips do not execute when the unit is turned off, so an on-board IC10 is only capable of turning the unit off if output pressure is too high, it is not capable of turning the unit back on once output pressure drops.
As of patch patch 0.2.4218.19726, the filtration system processing speed is based the pressure differential between the input and output. The unit will output filtered gas equivalent to 10 L (one pipe segment) at a pressure equal to 1/40th of the partial pressure of the gas being filtered in the input. As an example, if the input is at 10 MPa and is 20% nitrogen (so partial pressure of nitrogen is 2 MPa), a filtration unit with a nitrogen filter will output, per tick, an amount of nitrogen equivalent to 50 kPa (2 MPa / 40) in a 10 L volume (~0.205 moles at 20 C). Since the partial pressure difference between the input and output directly impacts the speed, pressurizing the input is beneficial, as is attaching the output to a single pipe segment followed by an active Volume Pump set to maximum throughput (10 L/tick) to ensure the output is at minimum pressure.
Characteristics
- It has a manual power switch.
- It consumes 10W of Power per Tick when idle and 44W when active.
- It has a separate Power Port and Data Port.
- It has an on-board IC10 chip slot.
- It has a pipe port (labelled "Input") for the gas mixture from which the designated gas(es) will be filtered.
- It has a pipe port (labelled "Filtered") for the designated gas(es) that have been filtered. (This is in line with and directly opposite of the input)
- It has a pipe port (labelled "Unfiltered") for any remaining unfiltered gases. (This is to the side)
- It can filter up to 2 different gases at once by inserting two different filters.
Note: When using an I/O slot reader chip, the filter slots are labeled as slot 1, slot 2 and slot 3(IC), with 1 being the slot closer to the inlet. When using an IC chip, the slots are labeled as slot 0, slot1 and slot 2(IC).
User Interface
A Filtration unit provides the following user interface:
| Name | Type | Function |
|---|---|---|
| Filter (Right) | Slot 0 | Port for a gas filter. If gas of the same type is present in the incoming mixture, it will be redirected out the "Filtered" pipe port. |
| Filter (Left) | Slot 1 | Another Port for a gas filter that functions the same as its twin slot. May contain the same or a different filter. |
| v | Slot 2 | IC10 placed in filtration unit (has 2 Input/Outputs) |
| On | Switch | Switches Filtration unit between turned on or turned off. (On=1/Off=0) |
