  • Patent number: 10458681
    Abstract: In accordance with exemplary inventive practice, a catalytic system and a temperature swing adsorption system are thermally integrated. The temperature range of the adsorption system is lower than the catalyst operating temperature. Benefits of inventive practice include reduction of total energy consumption and of generated waste-heat. Total energy consumption is reduced by transferring some of the waste-heat generated by the catalytic system into the adsorption system during the sorbent heat-up portion of the sorbent regeneration cycle. The heat is transferred using a thermal reservoir, which accumulates heat from the catalytic apparatus and transfers it to the adsorption apparatus at a later time, and which is repeatedly cycled as the sorbent is cycled. The catalytic system and the adsorption system can be inventively integrated in various ways to reduce the total energy consumed, and/or to modify the sorbent regeneration temperature profile, and/or to obtain an optimum power load profile.

  • Patent number: 10239018
    Abstract: The present invention provides for a reagent vaporization system. The reagent vaporization system includes a vaporization chamber located within a stream of hot exhaust gas. An aqueous reagent source located outside of the stream of hot exhaust gas provides aqueous reagent to the vaporization chamber. The heat from the hot exhaust gas vaporizes the aqueous reagent, which is then introduced into the stream of hot exhaust gas.

  • Patent number: 10156373
    Abstract: In accordance with exemplary inventive practice, a catalytic system and a temperature swing adsorption system are thermally integrated. The temperature range of the adsorption system is lower than the catalyst operating temperature. Benefits of inventive practice include reduction of total energy consumption and of generated waste-heat. Total energy consumption is reduced by transferring some of the waste-heat generated by the catalytic system into the adsorption system during the sorbent heat-up portion of the sorbent regeneration cycle. The heat is transferred using a thermal reservoir, which accumulates heat from the catalytic apparatus and transfers it to the adsorption apparatus at a later time, and which is repeatedly cycled as the sorbent is cycled. The catalytic system and the adsorption system can be inventively integrated in various ways to reduce the total energy consumed, and/or to modify the sorbent regeneration temperature profile, and/or to obtain an optimum power load profile.
