Abstract: A load-following reactor system (150) and associated facilities for improved control of a reactor under varying loads. The load-following reactor (152) may be a tube-cooled reactor for methanol synthesis. A reactant may be controlled by at least one valve element (160, 162) such that a portion of the reactant is fed to the reactor (152) through the reactor tubes (190), and a portion of the reactant is fed to the reactor after being heated in a heat exchanger (156). The heated portion of the reactant may be fed to the reactor (152) after the tubes (190). The valve element (160, 162) may be controlled based on a temperature of the reactor (152) and/or a flowrate of reactant feed to adapt the temperature of the reactor (152) to the changing reactant flowrate.
