CHEMICAL PROCESS OPTIMIZATION METHOD THAT CONSIDERS CHEMICAL PROCESS PLANT SAFETY
First Claim
1. A method for safely operating a chemical process plant comprising:
- measuring, for each of a plurality of sets of proposed process conditions for a particular chemical process within a particular chemical process plant, a pressure rise rate following a deliberate contained ignition of at least one material within the particular chemical process, to provide a plurality of pressure rise rates that corresponds with the plurality of sets of proposed process conditions;
selecting from the plurality of pressure rise rates a particular pressure rise rate that allows for a safe operation of the particular chemical process within the particular chemical process plant; and
implementing the particular chemical process within the particular chemical process plant while using a particular set of process conditions from the plurality of sets of reactor conditions that corresponds with the particular pressure rise rate from the plurality of pressure rise rates.

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. As an adjunct, the particular chemical reaction may also be subsequently and additionally optimized with respect to an ancillary parameter, such as product yield or feedstock utilization.
