Flare loads from tower relief dynamics in an ethylene plant
- M.W. Kellogg Co., Houston, TX (United States)
Today, environmental, health and safety considerations are quite stringent necessitating rigorous evaluation of relief system designs. Conventional approaches to determine relief loads from distillation columns often lead to the over design of relief systems by very large margins. In addition, these approaches cannot account for the actual dynamics of relief situations resulting at times in the incorrect identification of design-setting relief scenario. Dynamic simulation of tower systems overcomes these limitations by rigorously determining dynamic responses including the effects of any acceptable instrument action. This allows realistic quantification of relief loads and correct identification of the design-setting relief scenario, resulting in safe, yet not overly conservative relief system designs. The paper presents the specific modeling approach and results of dynamic analysis of tower systems in an ethylene plant and compares the results with those obtained by conventional methods.
