Pressure relief device (PRD) science

Butane cartridge are the essential engine of convenience, powering camping stoves, heaters, and culinary torches. However, their compact and disposable nature hides a critical inner complexity. At the heart of their safe operation lies a small but vital component: the safety valve. A failure in this system is not a mere malfunction; it can lead to catastrophic events like explosions or violent projectile releases. The Physics of Butane and Cartridge Design Butane is a liquefied petroleum gas (LPG) prized for its high energy density. Its storage relies on keeping the substance under pressure as a liquid, with gaseous butane occupying the headspace. However, container strength alone is insufficient against abnormal […]
