Predicting Operating Regimes in Heavy Gas Oil Hydrotreating Reactors Jinwen Chen and Mugurel Munteanu CanmetENERGY, Natural Resources Canada One Oil Patch Drive, Devon, AB, T9G 1A8, Canada Hydrotreating (HDT) or mild hydrocracking (HDC) of heavy gas oil or vacuum gas oil is an important step in...

C5 Metathesis for Increased Propylene Production

Mar 14, 2011
Robert J. Gartside
The production of on-purpose propylene via the metathesis of ethylene and butenes now exceed 6% of the total propylene. The supply of butenes is tightening worldwide due to both the increased demand for metathesis feedstocks and the increased demand for butadiene. The C5 cut from steam crackers has...

Use of Process Simulation In Ethylene Plant APC and Dynamic Optimization

Mar 14, 2011
Akitoshi Takinami, Ravi Nath
Showa Denko owns and operates a large Ethylene plant in Oita, Japan. Depending on the economic environment, plant objective is a combination of Energy Efficiency and Production Capacity. In order to achieve these objectives, Showa Denko had contracted Yamatake and Honeywell to design, configure and...

Exploitation of Low-Grade Heat In Site Utility Systems

Mar 14, 2011
Ankur Kapil
The site utility system provides the heating, cooling load along with power production for the processes on the total site. Low-grade heat is available in large amount across the process industry from temperatures of 30 o C to 250 o C as gases (e.g. flue gas) and/or liquids (e.g. cooling water)...

Novel Additives to Improve Resid Quality

Mar 14, 2011
Parag Shah
With an increasing focus on resid upgrade and bottom of the barrel conversion over the years due to economic advantages, refiners are increasingly processing heavy crudes that yield higher residue content. These crudes are also higher in salt, metal and sulfur content. Often in these cases, there...

Petroleum Resid Conversion: Opportunities and Limitations

Mar 14, 2011
Irv Wiehe
In the conversion of vacuum resids one has the option to form coke as a byproduct or to devise conversion processes that prevent coke formation while forming a heavy liquid byproduct. The theme of this presentation is that both options can be greatly improved over current commercial practice but...

Prevention of CUI: “ Roadmap to Managing CUI ”

Mar 14, 2011
Klaus Bormuth
This paper details CUI cases as well as the means for preventing, finding and repairing them. Approaches and procedures for managing CUI are described leading to a document “Roadmap to Managing CUI” which can be modified to company specific requirements. In recent years more problems with CUI in...

Industry Standards for Composite Repair Systems

Mar 14, 2011
Julian Bedoya
ABSTRACT A significant amount of work has transpired over the past several years in generating consensus-based standards that include ASME PCC-2 and ISO 24817 for developing composite repair systems. The intent in developing these standards has been to provide industry with guidelines for designing...

Reducing the Load on Cooling Towers through Revamping of Individual Coolers

Mar 14, 2011
Graham T. Polley
The engineering of cooling water systems involves a consideration of both hydraulic and thermal behaviour. Unfortunately this is often ignored. For instance when engineers seek to reduce the thermal load on cooling towers they will often opt for increased heat recovery (via improved heat...

Scale-up of Advanced Methanol to Olefins (MTO) and Olefins Cracking Process (OCP)

Mar 14, 2011
Eric Romers, John Senetar
Abstract: The conversion of methanol to olefins (MTO) is a means to produce ethylene and propylene from feedstock derived from sources other than crude oil or condensates. Methanol is widely produced from natural gas or coal at locations with abundant reserves. By utilizing methanol derived from...

Chemical Insights Indicate Process Opportunities for Residue Processing

Mar 14, 2011
Murray R. Gray
The vacuum residue fraction of petroleum is one of the most complex mixtures of compounds known, one which continues to defy comprehensive analysis. The combination of complexity, diversity, and aggregation of the asphaltenes has enormous implications for upgrading reactions and phase behaviour...
