The air receiver tank has three main functions in your compressed air system: It stores compressed air that can be used for short, high-demand events. It provides a steady air signal to compressor controls. When used as a "wet tank", it acts as a secondary heat exchanger, increasing the efficiency of your air dryer.

An air receiver tank is an important component of a compressed air system. The tank is sized 6 – 10 times the flow rate of the compressor system. The receiver tank is usually 150 cubic feet (minimum) for compressors with a rating of 25 scfm at 100 psi. The tank is a reservoir of compressed air that can be used during peak demand.

1.1. Compressed air energy storage concept. CAES, a long-duration energy storage technology, is a key technology that can eliminate the intermittence and fluctuation in renewable energy systems used for generating electric power, which is expected to accelerate renewable energy penetration [7], [11], [12], [13], [14].
Compressed air energy storage is a promising technique due to its efficiency, cleanliness, long life, and low cost. This paper reviews CAES technologies and seeks to demonstrate CAES''s models, fundamentals, operating modes, and classifications.
The Engineer quotes Garvey as stating that " the UK should aim to install 200GWh of CAES, with a cost for the energy storage alone of between £0.2bn and £2bn depending on what compressed air stores are adopted. He believes a further sum of up to £10bn may be required for the associated energy conversion equipment ".

As promising as compressed air appears as a storage medium, it does have some drawbacks. When air is compressed, it heats up. When it expands, it cools. Cold air isn''t as effective at producing power when it is run through a turbine, so before the air can be used, it needs to be heated, frequently using natural gas, which produces CO …
