Black, R B

Apparatus for use in the separation of at least one gaseous component from the combustion products of a hydrocarbon fuel and air is described comprising: (a) a diesel engine in which a mixture of the fuel and air is subjected to a first stage of combustion yielding primary products of combustion containing at least 6% by volume of free oxygen, (b) a secondary combustion unit comprising an elongated tubular element defining an elongated secondary combustion chamber having an inlet end and an outlet end, (c) an end closure wall at the inlet end of the secondary combustion chamber, (d) means for introducing primary combustion products and secondary combustion fuel through the end closure wall into the inlet end of the secondary combustion chamber, (e) a discharge connection for delivering secondary combustion products from the outlet end of the secondary combustion chamber, (f) a cylindrical heat shield in the inlet end portion of the elongated secondary combustion chamber, (g) a cylindrical shell forming a housing for the secondary combustion chamber, (h) means for separating at least one gaseous component from the secondary products of combustion, (i) a stripper for separating the absorbed carbon dioxide from the absorber liquid and including indirect heat exchange means carrying a heat exchange fluid for heating the absorber liquid, (j) and an indirect heat exchange system for absorbing heat from the tubular element of the secondary combustion chamber and being connected to the indirect heat exchange means for heating the absorber liquid in the stripper.
