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:

1. Input - Starting gas network that you want to filter from
2. Output - Filtered gas
3. 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.

Warning: If run without filters or the filters are exhausted, all input gases will be moved directly to waste!

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 difference between the pressure of input and higher pressure of the two outputs. If the higher-pressure output is equal to or higher than the input pressure, the unit will process an amount of input gas equivalent to 10 MPa per litre, per tick, with the amount pushed to the two outputs based on the partial pressure of the gas being filtered in the input. For example, if a unit is set to filter nitrogen, and the input is 20% at 10 MPa, and the higher of the two outputs is at >= 10 MPa (for example, if the waste output is connected back to the input), then the unit will push, per tick, 2 MPa-litres (ie. 200 kPa in a single 10 L pipe segment) to the filtered output, and 8 MPa-litres to the waste output.

If the pressure of the highest-pressure output is less than the input pressure, the unit will process per tick will be equal to 10 MPa*L + (PressureDifferential * 3.16885) MPa*L, where the PressureDifferential is the input pressure minus the output pressure, in MPa. As above, this output is split between the filtered output and the waste output based on the partial pressure of the filtered gas in the input. As an example, if the input pressure is 10 MPa at 20% nitrogen, and the higher-pressure of the outputs is at 2 MPa, the unit will process 1 + (10-2) * 3.16885 = 35.351 MPa*L, which is equivalent to increasing the pressure of a single 10 L pipe segment by 3.5351 MPa. 20% of this, or 7.07 MPa*L, would be pushed to the output (if the output is a single 10 L pipe segment, this would increase its pressure by 707 kPa), and the remaining 80% (28.28 MPa*L) would be pushed to the waste output.

In effect, if the waste output is connected to the input, and the filtered output is a single pipe segment (followed by a pump), the rate of output for the filtered gas will be 10 kPa per tick multiplied by the percentage of gas in the input that matches the filter (ex. if 20% nitrogen, 200 kPa to that single pipe segment per tick). If both the outputs are instead single pipe segments fed into volume pumps, so they remain at 0 pressure at all times, the rate of output of the filtered gas will be the percentage of the gas in the input that matches the filter multiplied by 1 MPa + 31.69% of the pressure of the input (ex. 10 MPa input, 20% nitrogen, the single pipe segment on the filtered output would gain 0.2 * (1 + 3.169) = 834 kPa per tick).

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.
  • Inserting two of the same type of filter does not increase filtration speed.

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)
