VUV Analytics, Inc. has recently completed an investigation with coker naphtha samples that indicates PIONA+ can be used to report compound class analysis of non-conjugated diolefins, conjugated diolefins, cycloolefins, and sulfur compounds. Individual analyte speciation is also possible for many of these compounds. Olefins, especially conjugated diolefins, are known to cause fouling of refinery processes and to negatively impact product quality. PIONA+ shows the potential for quickly characterizing the most problematic compounds…
