Justification and Engineering Design for the On-Line Monitoring and Automation of a Congruent Phosphate/pH Program
Michael E. Rogers, Ian Verhappen, Stephen Porter · 1992
Abstract Failures of convection tubes in two of Syncrude’s three hydrogen plants were traced to difficulties in carryover of boiler water into the steam and difficulties associated with controlling manually all the variables in a congruent phosphate pH program. To overcome this unacceptable situation, the introduction and use of a number of on-line analyzers was recommended. This paper examines the technical justification for using each analyzer, the actual engineering design that was required for their installation and the financial returns for carrying out the project. At the time of writing this paper, all the engineering work is complete, but vendor selection and installation are still to be done.
