✦ Synopsis

Apart froin the chemical considcratious involved in thc manufacture of spnthctic nminonin, the commercial npplicntions of the proccss have lcd to considernble iniprovcinciit in tlie design of conipressing plant. Before detailing such designs, Iiowevcr, it would, perhaps, bc as \.ell to give a bricf outline of various synthetic aiiiinonia processes so that seine idca of the problcms to bc solvcd inay be gaincd.

The co~nplete invcstigation of the cheinical equilibriuiii of nitrogen, liydrogcu and ammonia is due to IIaEcr. TIis scicntific work found iinincdiate prncticnl application and led to the development of the I-Inbcr process for tlie innnufacture of synthetic ammonia. The working of this proccss rnny be briefly sirriirilariscd as fOllO\S :-Water gas (CO + 11,) is niixcd in a suitable proportion with n producer gns (CO -+ 2 1 Q Wahr vnpour (H,O) is tlicn added to tlic iiiixtitrc and the gases are passcd ovcr n cntalyst lieatcd to 400' or 500" C.
