Abstract
A system is provided for energy recovery. The system includes a heat recovery unit. The heat recovery unit is configured to receive at least one of heat or steam from a methanization reactor operating to convert carbon dioxide (CO2) and supplied hydrogen (H2) via methanization to produce methane (CH4), generate energy using at least one of the heat or the steam from the methanization reactor, and supply the generated energy to at least one of a carbon/carbon (C/C) preform production process, a separator, or another system.
Claims18
A system for thermal energy recovery, the system comprising:
- a heat recovery unit;
- a carbon/carbon (C/C) preform production process unit configured to perform a carbon/carbon (C/C) preform production process which generates off gases;
- a separator;
- and
- a methanization reactor operating to convert carbon dioxide (CO2) and supplied hydrogen (H2) via methanization to produce methane (CH4),
- wherein the heat recovery unit is configured to:
- receive at least one of heat or steam from the methanization reactor;
- recover thermal energy using at least one of the heat or the steam from the methanization reactor;
- and
- supply the thermal energy to the carbon/carbon (C/C) preform production process and the separator,
- wherein the separator is configured to utilize the heat to separate the CO2 from the off gases and is configured to provide the CO2 to the methanization reactor;
- and
- wherein the methanization reactor is configured to feed the CH4 into the into the C/C preform production process.
A method for thermal energy recovery, the method comprising:
- receiving, by a heat recovery unit, at least one of heat or steam from a methanization reactor operating to convert carbon dioxide (CO2) and supplied hydrogen (H2) via methanization to produce methane (CH4);
- recovering, by the heat recovery unit, thermal energy using at least one of the heat or the steam from the methanization reactor;
- and
- supplying, by the heat recovery unit, the thermal energy to a carbon/carbon (C/C) preform production process and a separator,
- wherein the separator utilizes the thermal energy to separate the CO2 from off gases generated by the carbon/carbon (C/C) preform production process and provide the CO2 to the methanization reactor to perform a methanization process in order to produce CH4, which is fed into the C/C preform production process.
