Abstract
A cylindrical shift converter () is disposed within an annular heat exchanger () which has an outer wall (). A plurality of spiral rods () create a plurality of spiral gas passages () between the outer wall and a thin shell (). The outer diameter of the thin shell is at least about 3/16 inch (about 4 mm) less than the inner diameter of an inner wall () of an annular hydrodesulfurizer (), to facilitate inserting the shift converter and heat exchanger into the hydrodesulfurizer to form a unitized assembly (). The spiral passages open into the hydrodesulfurizer.
