Ionic Liquid Piston Based Gas Compressor

  • A Pump Designed for Toxic/Explosive Gasses with low part count and high reliability
  • Can this be done with a durable Gasholder / Gasometer (perhaps with extra depth to prevent a pressure based leak/allow more travel distance and thus more pressure),

and some sort of actuator, a hydraulic piston etc, to push the top down while it is sealed, then use some sort of valve to take the pressurized gas out, rinse and repeat? Wouldn't requre lubrication of the piston, and perhaps could be staged?

  • Main issues may be:
  • "dome" section strength
  • pressure gained per travel distance centimeter down (ie will some huge tower be needed (anyone know the math?)
    • Granted this may be solved via larger diameter "pistons", and multiple compression pistons in series?

Gasholder-Pressure Piston Version

General Description

  • Uses a modified Gasholder with hydraulic/pnuematic pistons on top of the "dome" part, as well as a High Pressure Gas Hose, and a taller outer cylender to allow for more compression (can be modular/user selectable?)
  • Below the dome, under water is a low pressure inlet gas bubbler/output
  • May acheive less pressure and/or take up less space, BUT it would essentially be a Gas Holder with slight modifications, and thus may be more modular
  • Main concerns are how to attach the dome to the output while still allowing it to be mobile (~250bar rated hose?), also fittings + welds etc must be sturdy enough to handle the pressure (don't want a spacex cryo test type situation...)
  • Also can be used in a Cascade Setup, so small size may work for more modularity
  • Will require compressed air or fluid, but this can be easier to do with non-combustable, low diffusion gasses for pnuematic, also with the Powercube hydraulic power is common in the ose machines
  • Supposedly this was sort of done via passive weights on old gasholders, sso this is semi-proven, just more controlled, and most likely increased pressure ceiling

Basic Process

  • The gas floats up and is trapped by the sealed valve at the end of the dome's hose
  • Once it is "full" the pistons engage and push the dome down
  • This compresses the gas need to see how much per cm^3 pushed down 1cm (also if diameter of dome base etc affect this)
  • Once it has reached the "Base" of the stroke cycle and/or the desired pressure, the output valve is opened, and it is released at the pressure set by the regulator
  • This then loops

Basic Sketch

Basic, Per Module, Non-Exact BOM

  • 1x Gasholder (most likely more than 1x height)
  • 2x gas valves
  • 2-3x gas flow meters
  • 2-3x pressure meters
  • 1x gas pressure regulator (low to high)
  • 1x High Pressure Gas Hose
  • 3x High Pressure Gas Hose Fittings (for dome connection + final valve module)
  • 1x Low Pressure Gas Hose Fitting (for gas in)
  • 1x arduino (+ needed sheilds for sensors in to valves for gasses, and pistons)
  • 2x+ Pistons (Hydraulic or pnuematic depending on needs etc)
  • ?x Power Cubes (Depending on needs)
  • Hydraulic and/or pnuematic circuit for pistons
  • Various bolts, sheet metal etc for mounting pistons to dome
  • Optional (?) water in/out ports (drain plug seems essentiall, but addition via top gap may be possible? (also then may require extra ports/valves etc)
  • Power Supply (for arduino + electric power cubes (if used) )
  • Some sort of display/io for monitoring + control etc (simple lcd + dial will work + port connections?)
  • Make it pallet mounted for ease of modularity and transport?

Pumped Water Version

  • Uses high pressure water, and a valve system to make water push the gas up, may require extra valves, and higher pressure?
