Abstract: A method for assuring safety of a particular chemical process plant includes measuring, for each of a plurality of sets of proposed process conditions for a particular chemical process within the particular chemical process plant, a pressure rise rate following a deliberate contained ignition of at least one material used within the particular chemical process. From the resulting plurality of pressure rise rates that corresponds with the plurality of sets of proposed process conditions a particular pressure rise rate that allows for a safe operation of the particular chemical reaction within the particular chemical process plant may be selected. The particular chemical process may be implemented within the particular chemical process plant while using a particular set of process conditions from the plurality of sets of process conditions that corresponds with the selected pressure rise rate.

Abstract: This invention relates to a process for reducing the corrosion rate of iron-containing vessels within an ethylene glycol distillation system. The inventive process includes the addition of an additive component of sodium nitrite and sodium hypophosphite into such iron-containing vessels, to thereby react with iron of the inside walls and form a protective coating thereon. This process reduces the corrosion rate in iron-containing vessels of the apparatus, and reduces the catalytic effects of iron corrosion products within the system. Thus, not only is the on-stream time of the vessels extended, but also product quality is improved by reducing the aldehyde content of the final ethylene glycol product.

Abstract: A reactor and heat exchanger assembly is provided with the heat exchanger integrally affixed to the reactor exit head and adapted to immediately cool reactor gases from the reactor.

Abstract: In an ethylene oxide process, the stripping and reabsorption operations, normally carried out in separate vessels, are carried out in a single vessel which is divided by a baffle into separate sections where reabsorption and stripping are carried out.
