In 2016 we hope to give more accurate sizing for the tanks by providing the 80% liquid fill volume. We calculate this volume by measuring the tubes volume without the rounded heads on the top and bottom of the tank. Liquid propane has density of about 1.28lbs/L, while butane is about 1.33lbs/L. Due to the difference between these densities your solvent mixture will change how much solvent you can add into the system. once you have decided on the mixture plug the percentages into this equation to get the density of the mixture
simply multiply the tanks volume by ptotal and you get your tanks fill weight regardless of solvents used or the exact dimensions.
2lb 15.5L – The 10″ x 12″ 15.5L recovery tank holds 19 lbs of butane or 17 lbs of propane.
5lb ASME 30L The ASME 5lb extractor 30L tank holds 38 lbs of butane or 33 lbs of propane.
5lb 38.9L the 38.9L tank holds 48 lbs of butane or 42 lbs of propane.
8-10lb 42.3L The 42.3L 12″ x 24″ tank and the 10″ x 36″ tank hold 52 lbs of butane or 46 lbs of propane.
10lb 66.7L The massive 12″ X 36″ 66.7L tank holds 76 lbs of butane or 67 lbs of propane.
These figures are calculated at 80% fill volume which is considered safe for your pressure vessels. Never fill your pressure vessel beyond 80% fill volume!
