  • Heat recovery technique for catalyst regenerator flue gas
    Patent number: 7404891
    Abstract: A technique for recovering heat from a high temperature effluent stream from catalyst regeneration or the like, comprising processes and means for: (a) passing the effluent stream in heat exchange relationship in a steam generator with boiler feed water to produce high pressure steam and partially cool the effluent stream; (b) passing the partially cooled effluent stream from the steam regenerator in heat exchange relationship to preheat high pressure boiler feed water and further cool the effluent stream; and (c) passing the preheated boiler feed water to the steam generator. The apparatus and processes for thermal energy recovery may be used to treat hot regenerator effluent from FCC or OTO-type processes, thereby producing a cooled flue gas stream to discharge to ambient atmosphere.

  • Control unit for a motor vehicle which can be accommodated in a trim component
    Patent number: 4564883
    Abstract: The invention relates to a control unit which comprises one or more switches and is capable of integration into a trim component installed inside the passenger compartment of a motor vehicle. The control unit is designed in such a manner that, after fitting the trim which accommodates it, a baseplate can be fixed to the trim, the baseplate accommodating the bases of all the control elements intended for the control unit.
