On January 7, 2013, a lithium-ion battery caught fire on a Boeing 787 Dreamliner. Watch this PStv® Safety Moment for an examination of the root causes of this incident and the implications for electric vehicles. In this video, we also present process safety design lessons learned to help you prevent future incidents.
A major petroleum company recently increased production capacity and required an analysis of its existing relief systems to validate performance and design. As a result of increasing production capacity and debottlenecking studies, several refinery units were found to be operating at charge rates higher than the design basis for the relief systems documentation.
An international oil company was preparing to startup a state of the art acid gas injection facility and needed to benchmark against current industry practices for handling large quantities of toxic gas at high pressure.
A supplier was being sued because his product, when delivered, went into the wrong storage tank. This led to a chemical reaction and release of chlorine to which the plaintiffs claimed they were exposed.
Exothermic reaction processing must be concerned with potential consequences when heat released by the reaction exceeds that removed by the reactor coolant system, a situation known commonly as a runaway reaction. We have investigated a complicated reaction process in which two exotherms can occur — the process of making the desired product, o-nitroaniline (o-NA), from ammonia and o-chloronitrobenzene (T Onset around 140° C), and the decomposition of the product, o-NA (T Onset around 225° C). A severe industrial loss occurred in 1971 at a plant producing o-nitroaniline, an incident that has been the subject of several AIChE loss prevention presentations and papers. In this article, we take a closer look at the chemistry involved, and the ability to use thermo-kinetic analyses to understand the reactions involved, and how these influenced the accident that occurred. Further, we present the progress we've made towards predictive models for the kinetics and the pressure-time data. Several useful generalizations have evolved. First, is the need to include experiments that use stoichiometric mixtures when assessing exothermic reactions. Second, is the need to understand the role of reaction intermediates, and how they may influence the operation of the plant.
