Abstract: Apparatuses and methods for reforming of hydrocarbons including recovery of products. A reforming-zone effluent is separated into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream may be passed separated into an H2 rich stream and a tail gas stream in a PSA. The tail gas may be passed through an absorber and then passed through a membrane to form a second H2 rich stream and a liquid stream. A second absorber is used to recover C3/C4 hydrocarbons. The two absorbers may be stacked on top of each other.

Abstract: Processes and apparatuses for heating a feed stream for a reactor which has a charge heater. At least one process stream provides heat so that a pre-heated feed stream passed to the charge heater is a vapor stream. The process stream may be the heated stream from the outlet of the charge heater. Alternatively, the process stream may be the effluent stream from the reactor that has been heated.

Abstract: Processes for controlling liquid organic hydrogen carrier processes are described. The processes include flow control of hydrogen as the primary variable with toluene make-up based on reactor conditions. Make-up hydrogen gas is provided via a flow controller which can be adjusted by the operator. A pressure controller on the separator is used to adjust the temperature at the reactors with a temperature controller. The inlet temperature to the reactors is maintained by heat exchangers, such as steam generators. The reaction conditions are monitored by temperature measurement and the inlet and/or the outlet of the reactor. When hydrogen feed rates are adjusted, the unit operations must increase or reduce the toluene to balance this situation. A differential temperature controller is used to reset the toluene flowrate to the reactor to achieve the desired processing objective.

Abstract: Processes for hydrogenating toluene to methylcyclohexane (MCH) and dehydrogenating MCH to toluene with minimal to no by-products, thereby ensuring minimal loss of hydrogen are described. MCH acts as a liquid organic hydrogen carrier, and it can be transferred in storage vessels and/or pipelines for several thousands of miles to the final destination with very minimal to no degradation.
