Host: Evan Hyde Guests: Dave Geddes - Mr. Geddes background, he managed PIMS group at Bechtel for 15yrs. For the past 15yrs, he has been doing feasibility studies for new refinery projects and updating refinery LP systems. - Crude oil supplies and characteristics with a focus on traditional and nontraditional crudes, naphthenic vs parafinic crudes and properties. - What is an assays and how differences can be expected between the predicted vs actual in the model and in the plant. - Certain assays vary over time over time - which crudes vary the most and why? - Impacts on key refining processes including mischaracterization of yields for novel feedstocks. For example how paraffinic cracking yields are better for FCC but naphthenic are better for HDC - Training at Refcomm > Petroleum Refining Economics Links Haverly's H/CAMS SimSci’s Crude Suite AspenTech’s PIMS software Minas Crude Assay - 1999 http://refiningcommunity.com/ https://www.facebook.com/TheRefiningCommunity/ #REFCOMM Twitter: @RefiningCommunity or @Cokingcom Variety of Linkedin groups as well.
