Abstract: A method for heat integration between a chemical synthesis plant that runs an exothermic reaction and (ii) and a partner plant that generates a working fluid such as steam (e.g., runs a power cycle). The present disclosure describes both internal and external heat integration. Internal heat integration may provide heat from the exothermic reaction (e.g., from methanol synthesis) to a reboiler associated with a distillation column of the chemical synthesis plant. External heat integration may use heat from the exothermic reaction to preheat a condensed water stream (which stream is downstream from the turbine and condenser of the power cycle). Such reduces the need for bleed off the turbine to preheat condensed water as part of the power cycle. A bleed off the turbine provides heat to the reboiler associated with the distillation column of the chemical synthesis plant. Heat integration provides overall improved energy use within both plants.

Abstract: A load-following reactor system and associated facilities for improved control of a reactor under varying loads. The load-following reactor may be a tube-cooled reactor for methanol synthesis. A reactant may be controlled by at least one valve element such that a portion of the reactant is fed to the reactor through the reactor tubes, and a portion of the reactant is fed to the reactor after being heated in a heat exchanger. The heated portion of the reactant may be fed to the reactor after the tubes. The valve element may be controlled based on a temperature of the reactor and/or a flowrate of reactant feed to adapt the temperature of the reactor to the changing reactant flowrate.

Abstract: An improved reactor comprising a shell and at least one reactor internal component. The reactor internal component includes a tube bundle comprising a plurality of tubes attached by at least one tube support plate comprising at least one radial strut and at least one bracket configured to secure to at least one tube of the tube bundle. The tubes are arranged in concentric bands about a longitudinal axis of the reactor. The reactor comprises a gas inlet plate, a catalyst support plate, and a top plate.
