Analysis of storage in Liquefied Petroleum Gas systems: Stationary Tanks vs. Cylinders

Abstract:

In Ecuador, liquefied petroleum gas (LPG) is used as an energy source for residential, commercial and industrial equipment. In its natural state this fuel is in gas phase, but for easiness of transportation and storage it is liquefied and stored in containers called cylinders (by spare) or tanks (stationary), where it is re-gasified for consumption. The present work mea-sures the remaining LPG that is returned in cylinders to the marketers, by 20 commercial and industrial users in Ecuador during a month, 8 with 15 kg cylinders and 12 with 45 kg cylinders. The average return was 3.82 kg/cyl. (25.49%) and 9.69 kg/cyl. (21.54%) respectively. Then, 8 safety parameters considered in the current Technical Standard in Ecuador were verified for these 20 facilities, and the results of those users who do not comply with these parameters are presented. Finally, some arguments are given about why there are economic and security advantages in the storage of LPG in stationary tanks over the storage in cylinders.
