Abstract:
Hydrocracking and fluid catalytic cracking (FCC) can generate sour water with cyanide content which can take various forms depending on conditions. Total, available (amenable) and free cyanide analysis using injection segmented flow analysis incorporating a gas diffusion manifold to handle hydrogen cyanide gas safely and either amperometric or photometric detection will be described, along with interferents and common pitfalls. Total organic carbon (TOC) analysis of boiler feed water can help to eliminate corrosive species in the heat exchanger system, prolonging life and lowering maintenance costs and downtime. The use of TOC measurements, both from in-line monitoring systems and benchtop analyzers will be described, with comparisons of the two approaches.
