On the basis of laboratory scale work and pilot experiment for electrochemical reduction of NB to PAP, the shape, maintenance and operation of such anode are discussed.

Electrochemical methods were applied to investigate the corrosion of A3 steel in FCC stripper water prepared in the laboratory. All experiments were conducted under ambient temperature.

Four kinds of corrosion inhibitors for drawn-and-ironed (di) material were studied by means of electrochemical method and rapid laboratory evaluation.
