ABSTRACT

This paper discusses the efforts to commission and validate an online Nuclear Magnetic Resonance Spectrometer [NMR] for the analysis of heavy feedstock to a cracking plant.  Reference will be made to ASTM D3764 – Standard Practice for Validation for Process Stream Analyzers (1).  Results from laboratory analyses of standards and plant samples will be presented.

 This paper was based on work performed almost entirely by Process NMR Associates, who regrettably are not acknowledged.
