Abstract: A process for reducing pressure of a vapor stream used for reducing a temperature or pressure in a reactor. A pressure of a vapor stream is reduced with a turbine to provide a lower pressure vapor stream. The vapor stream rotates a turbine wheel within the turbine. The turbine wheel is configured to transmit rotational movement to an electrical generator. Thus, electricity is generated with the turbine. The lower pressure vapor stream is injected into a reactor and reduces a temperature in the reactor or reduces a partial pressure of a hydrocarbon vapor in the reactor.

Abstract: A control process and apparatus provide feed forward control of stoichiometric proportions of hydrogen sulfide and ammonia to a thermal oxidizer and an ammonia scrubber, respectively. To account for unmeasured or uncalculated sulfur feed to the thermal oxidizer, a feed back measurement of sulfur dioxide and ammonia concentration is used to correct the flow rate of hydrogen sulfide to the thermal oxidizer and/or ammonia to the ammonia scrubber.

Abstract: Processes for controlling at least one process condition of a chemical processing unit with a turbine. In the processes, a flow of a fluid is adjusted with a turbine in order to provide the fluid with a flow associated with at least one process condition of a chemical processing unit. The turbine wheel is rotated within the turbine, and the turbine wheel is configured to transmit rotational movement to an electrical generator. The resistance of the turbine is modulated and adjusts the flow of the fluid through the turbine. A response time of at least one steady state process condition to a new steady state process condition of at least 10% difference is at least one second to reach 50% of the difference between the at least one steady state process condition and the new steady state process condition after modulating the resistance of the turbine.

Abstract: Methods and apparatus for recovering power in a hydroprocessing process are described. The method involves the use of a power-recovery turbine in place of, or in addition to, a control valve. A hydrocarbon feed stream is combined with a portion of a hydrogen stream. The combined stream is heated, and the heated stream is introduced into a hydroprocessing reaction zone having at least two beds. The heated stream is contacted with a first hydroprocessing catalyst to form a first hydroprocessed stream. At least part of a portion of the hydrogen stream is combined with the first hydroprocessed stream to form a first quenched hydroprocessed stream. The first quenched hydroprocessed stream is contacted with a second hydroprocessing catalyst to form a second hydroprocessed stream. At least a portion of the second portion of the hydrogen stream is directed through a power-recovery turbine to generate electric power.

Abstract: A process according to various approach includes flushing an intermediate transfer line between the first intermediate transfer line and the extract stream transfer line away from the adsorptive separation chamber to remove residual fluid from intermediate transfer line. The process may include directing the residual fluid flushed from the intermediate transfer line to a recycle stream to introduce the residual fluid into the adsorptive separation chamber.

Abstract: In a process for separating components in a feed stream by simulated countercurrent adsorptive separation, the process according to various aspects includes withdrawing an extract stream through one transfer line that contains residual fluid away from the adsorptive separation chamber. The process also includes directing an initial portion of the extract stream, including at least a portion of the residual fluid withdrawn through the one transfer line toward a first destination. The process further includes directing a subsequent portion of the extract stream withdrawn through the one transfer line toward a second destination.

Abstract: A process and system for monitoring and controlling the operation of a dehydrogenation reactor is provided. Samples of hydrocarbon streams are taken at sampling locations to be analyzed at a single gas chromatograph or other analytical equipment. Actions can be taken to modify the operation of the dehydrogenation reactor as necessary to maintain its operation within predetermined parameters. In particular, actions may be taken when a hydrocarbon stream exhibits an amount of cracking that is outside parameters. It is usually intended that actions will be taken on a gradual basis once or twice per day to reduce the cost of the process while still providing the necessary changes to operations.
