2 FACTORS OF PROGRESS TECHNOLOGICAL INNOVATIONS AND INCREASED FUNDAMENTAL INSIGHT 

Among the many technological innovations of recent years are the following examples  

The introduction of better materials of construction (e.g., in steam reforming) where the use of centrifugal cast 25% Cr/20% Ni steel tubes has permitted increasing the operating temperature and consequently the throughput. 

Better design of reactor internals (e.g., in phthalic anhydride synthesis), improving the rate and uniformity of heat removal by molten salts. 

More adequate shop techniques and increased shipping clearance, permitting the construction of multitubular reactors of large diameters containing up to 20,000 tubes.
