...-year alumina plant, the Bayer liquor flow rate is typically 10,000 to15,000 gallons per minute (gpm). As one can imagine, any small improvement in the process in such a huge operation would mean enormous profit to the alumina industry. Over the years tremendous efforts have been devoted to increasing...

... ABSTRACT Duplex stainless steels (DSS) have generally performed very well in the pulp mill environment. However, some corrosion and stress corrosion cracking (SCC) of duplex stainless steels has been reported in different pulping liquors. Studies have shown that corrosion and SCC...

... ABSTRACT Corrosion testing in black liquors from kraft pulp and paper mill evaporators has confirmed that carbon steel has stable passivity in weak liquors (15% solids content), unstable passivity in intermediate liquors (25% and 33% solids content), and corrodes actively in strong liquors (45...

... in simulated kraft cooking environments. The effect of macro and micro stress state, phase ratio (ferrite content), liquor temperature and sulphidity on SCC has been clarified on the base steel grades and their welds. Guidelines to prevent SCC in digesters are presented. The cooking environments in pulp...

... INTRODUCTION ABSTRACT In the pulp and paper industry, variability in the process and wood source may result in high corrosivity waste liquors, called black liquors. It is well documented that the concentration of organic extractives is wood species dependent and prior research has...
