摘要：Industry-standard thermal hazards screening is an effective and cost efficient tool to obtain the data required for the safe scale-up of new or altered chemical processes.Collected data can be used to characterize reaction kinetics, properly size process equipment（e.g.cooling systems, relief devices, condensers, knockout drums, etc.）, understand decomposition or unwanted side reactions, guide the selection of safe processing conditions, and calculate many important process-related parameters（i.e.heat of reaction, moles of generated gas, selfaccelerating decomposition or polymerization temperatures, and other）.This paper illustrates several widely-used thermal hazard screening bench-scale techniques that lend themselves to quickly identifying reactive hazards while providing directly scalable data for chemical process or storage facility design.A case study is presented on a phenol formaldehyde process, which remains an active process in the industry as it relates to a wide variety of uses like ablation, abrasives, coatings, composites, wood bonding, and much more.Example data are presented from various instruments with discussion of how the data are analyzed keeping chemical process safety as a priority throughout the discussion.A further discussion is provided on selection of the appropriate tool based on the testing goals.
