Gas Holder
(Redirected from Gasholder)
Contents
Basics
- Also known as a gasometer
- A device for low pressure gas storage
- It uses a similar mechanism to holding a cup upside down in water to trap gas for storage
- It acts as a buffer - removing the need for continuous gas production.
- In the traditional design the weight of the gasholder lift (cap) controlled the pressure of the gas
- Consists of two main parts:
- a deep tank of water that was used to provide a seal
- a vessel that rose above the water as the gas volume increased
- Common for old Gasworks, due to the lower technology of the time
- Although there are better modern options, they also tend to be more complex, and maitnence intensive
- Thus at least in certain applications, or as an intermediary, this may be of use due to the tradeoff of complexity and maitnence for overall size
Gas holder with an external fixed frame. Water provides a seal. The whole tank floats in a circular water reservoir, held up by the roughly constant pressure of a varying volume of gas. The pressure is determined by the weight of the structure, and the water providing the seal for the gas within the moving walls. Besides storing the gas, the tank's design serves to establish the pressure of the gas system.
Possible Future Uses
- Storing C02 rich exhaust for CO2 Enrichment (especially if pre-processed with a Gas Scrubber
- This would also produce (dilute?) carbonic acid, for better or worse
- Although it is not the best design for this purpose, it may act as a sort of Wet Scrubber , and this aspect could be optimized
- Addition of some sort of mechanism to push the cap down, could modify it to be a sort of Ionic Liquid Piston Gas Compressor
Existing Open Source Designs
- A Simple, Small Design by the youtube channel "NightHawkInLight" not usable for long term use etc, but good demonstration/proof of concept platform etc
