Abstract:
1. An insulated chemical reactor comprising: a reaction vessel having a wall with inner and outer surfaces; an evacuated insulation shell spaced apart from and surrounding said reaction vessel; at least one isothermal mixing baffle disposed within said reaction vessel; a phase separator in fluid communication with said baffle so that only one saturated or sub-cooled liquid phase of a heat transfer working fluid enters said isothermal mixing baffle; a temperature controlling helical channel coil fixed to said outer surface of said wall of said reaction vessel, said helical channel coil having at least two flat parallel walls disposed normal to and in contact with the outer surface of said wall of said vessel, thus defining an open helical channel coil fixed to said wall of said vessel, said helical channel coil having a winding pitch so that successive coils of said channel coil are spaced apart from each other, thus defining a closed path to receive a fluid to contact said wall of said reaction vessel, said wall of said reaction vessel being of a thickness less than that required for use under a given temperature and pressure regime, said channel coil serving to add structural strength to said wall of said reaction vessel, so that said reaction vessel with said channel coil fixed thereto can be operated under said temperature and pressure regime; said helical channel coil fixed to said outer surface to enhance conductive heat transfer and transfer of convective energy flow inside said helical channel coil through said wall of said vessel; and means to combine vapor from said phase separator and vapor from said isothermal mixing baffle and introduce said vapor into said helical channel coil.
