HYBRID HIGH-TEMPERATURE METHOD WITH ELECTRIC HEATING Russian patent published in 2024 - IPC H02J3/28 C01B3/24 H02J15/00 H02J3/14 H02J3/38 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for continuous implementation of one or more heat-consuming chemical processes (1) occurring at chemical production sites with formation of hydrogen. Method is characterized by that at least one heat-consuming process is carried out with electric heating, the maximum temperature in the reaction zone of the heat-consuming process is more than 500 °C, at least 50% of hydrogen from at least one heat-consuming process is directed through pipeline (17) for continuous processing in subsequent processes (51) and via pipeline (7) into local hydrogen network (4), and electric power required for implementation of at least one heat-consuming process is taken from external electric network (16) and at least one local energy source (11), wherein at least one local energy source (11) receives at least 50% of its annual energy demand from said local hydrogen network (4) and maximum 50% of energy from its annual energy demand is obtained with hydrogen, which comes directly from heat-consuming process, wherein at least in said local hydrogen network (4), hydrogen from heat-consuming process (7) is stored as an energy carrier, wherein at least one local hydrogen network (4) is supplied hydrogen (36) from at least one other chemical process (31), and wherein the total capacity of the local network of energy carriers is at least 5 GW⋅h. Invention also describes the use of said method as a minute reserve for a general-purpose electric network and use of local energy carriers of chemical production sites for accumulating electric energy.

EFFECT: use of the proposed invention enables to carry out the heat-consuming process continuously with regulation in accordance with the need when using excess energy, wherein the production capacity is independent of the presence of excess energy in the common power grid.
