碩士 / 嘉南藥理大學 / 職業安全衛生系 / 102 / Explosion accident arising from butadiene peroxide has been concerned for a long time. Therefore, safety of butadiene storage tank and way of maintaining material quality become significant. The present study investigates influences of butadiene storage temperature and time as well as “oxygen content and rust content in storage tank” on generation of peroxide. According to research results, butadiene dimer changes when the temperature reaches above 21℃ and presents an obvious rising trend when the temperature goes up to 27.6℃. Storage time is positively correlated with butadiene dimer production (a linear relation of Y=30.162 X), which demonstrates storage time indeed affects generation of butadiene dimer; furthermore, 15 days later, production rate of butadiene dimer will show a significant difference. With regard to oxygen content in storage tank, existence of oxygen contributes to generation of peroxide; when oxygen level is greater than 0.3%, peroxide formation is easily induced. Rust content of raw material indicates iron catalyzes generation of peroxide, so it’s necessary to minimize formation of rust and thus reduce generation of peroxide. In addition, this research conducts Hazard and Operability Analysis (HazOp), and develops HazOp Record Chart to perform hazard analysis. For the most dangerous equipment or pipelines on the site, oxygen-containing gas shall be released regularly as per a schedule in order for avoiding the risk of explosion arising from exposure of broken pipe (breakage caused by polymer generated from stranded materials or dead angle) to ignition source.
