Abstract: A process for reducing pressure of a vapor stream wherein the vapor stream rotates a turbine wheel within the turbine to transmit rotational movement to an electrical generator and generate electricity. The resulting lower pressure vapor stream reduces a partial pressure of a hydrocarbon vapor or is injected into a reactor to reduce a temperature in the reactor. A recovered electric power measuring system comprises at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data from a sensor on an electrical powerline connected to a generator of a turbine, the turbine in fluid communication with a vapor stream wherein the turbine reduces the pressure of the vapor stream and the resulting lower pressure vapor stream is injected into a reactor to reduce a temperature in the reactor or to reduce a partial pressure of hydrocarbon vapor in the reactor.

Abstract: Processes and apparatus for recovering energy from a petroleum, petrochemical, or chemical process are disclosed. The process comprises providing a fluid process stream in a petroleum, petrochemical, or chemical process zone having a direct current power input; controlling a flow rate of the process stream by directing at least a portion of the process stream through a first power-recovery turbine to generate electric power as direct current therefrom; and providing the recovered direct current to the direct current power input of the process zone.

Abstract: Systems and methods are disclosed for detecting temperature excursion in a chemical plant or petrochemical plant or refinery. Aspects of the disclosure provide an enhanced control system for a reactor, such as in hydroprocessing. The enhanced control system may provide early warnings of impending undesirable events, directly or indirectly manipulate certain process variables to reduce undesirable outcomes, and/or directly or indirectly manipulate of certain process variables so as to place a reactor unit in a “safe park” state. This may avoid a high temperature trip, depressuration, associated operating risks, allow for faster recovery from temperature excursions, and/or avoid unplanned emergency shutdowns of the reactor, chemical process, plant, or refinery.
