Questions and answers (Q and A) reported at the NPRA Convention (1979) covered hydrogen manufacturing and purification, including hydrogen utilization in refineries, the use of purification processes for by-product hydrogen, and cryogenic hydrogen-purification units; the presence of a bellows expansion joint in the transfer line between reformer outlet and waste-heat boiler; combustion (oxygen) control in steam-reforming furnaces; hydrotreater problems, including modification of the inlet distributor to obtain uniform scale and coke deposition, procedures for avoiding excessive exchanger fouling in a 700 psig reformer feed pretreater, the reduction of exchanger fouling in a diesel hydrodesulfurizer, metals that withstand corrosion in effluent exchangers of a naphtha hydrotreater, corrosion problems in naphtha processing at high (> 15 ppm) chloride levels, smothering with steam in cases of tube rupture in a hydrotreater reactor charge heater, the processing of coker naphtha in a simple low-pressure naphtha hydrotreater with once-through hydrogen, and the prevention of fouling and pressure drops in hydrotreating pyrolysis naphtha.
