Experimental and theoretical investigation of acetone evaporation

Abstract

In the case of flammable liquids, it is known that is not the liquid itself that is prone to ignition, but the vapour of the hazardous substance. For these substances, it is particularly important to be able to determine exactly how much vapour is produced and how it spreads. The substance to be tested is acetone. That is a common substance in households in various forms (cosmetics), but is also frequently used in the chemical industry. Different models are available for calculating the evaporation rate, which are compared in this study with the evaporation experiments carried out. The aim is to select a suitable model in relation to the measured results.

Gas explosion venting of 20-litre vessel with and without various length of vent ducts

“…They can be caused by false valve openings, improper seals, incorrectly fitted flanges, mechanical injuries of closed systems, storage and handling devices etc. Evaporation of liquid, spread of the gas or developing of dust clouds can be prone to ignition in open field and also in closed areas (Tugyi et al, 2021). Dust safety science report made by Cloney (Cloney, 2021) summarized incidents worldwide between January and June of 2021. related to dusts: 8 fatalities, 28 dust explosions and 51 fire incidents.…”
