Apparatus is disclosed for synthesizing ammonia from an ammonia feed gas passing to an ammonia synthesis converter from a heat exchanger. The synthesis converter is close coupled through a channel to a heat exchanger and a conduit extends through the channel and is adapted to be connected to the tube side of the heat exchanger.

Ammonia conversion process

Apparatus for synthesizing ammonia from an ammonia feed gas passing to an ammonia synthesis converter from a horizontally disposed heat exchanger. The synthesis converter comprising a shell and catalyst holder positioned within and spaced slightly from the shell to provide an annular passageway therebetween, is close coupled through a channel to a heat exchanger and a conduit extends through the channel and is adapted to be connected to the tube side of the heat exchanger.

Ammonia converter

A heat exchanger is disclosed which comprises an outer shell, a bundle of heat exchange tubes within the shell and positioned within a tube sheet adjacent one end thereof, and a shroud spaced between the shell and the tubes. The exchanger is constructed so that hot incoming fluid passes over the heat exchange tubes inside of the shroud and then, in its cooled state, passes along the back face of the tube sheet and between the outer surface of the shroud and the inner surface of the shell, so that thermal stresses in the tube sheet are minimized.
