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...

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...

Life Cycle of Aluminum Plate Fin Exchangers

Mar 14, 2011
Dr. Hubert Koepf
Abstract: Corrosion, blockage, fouling, and mechanical/thermal overload are the key degradation mechanisms that operators need to control to avoid premature failure of their aluminum plate fin heat exchangers. The paper will describe these degradation mechanisms as well as how to incorporate finite...

Cooling Water Issues – Cause and Solutions to Microbiologically Induced Corrosion

Mar 14, 2011
Carl G. Matherne
In the 2007 turnaround at the BASF FINA PETROCHEMICAL L.P. Ethylene Steam Cracker, severe damage was discovered in the cooling tower to process exchangers. Over 41 exchangers had been replaced or required total tube bundle replacement within the first seven years of operation. Several of the units...

Furnace Penetration Sealing Systems - Engineered Solutions for Cracking Furnaces

Mar 14, 2011
Malcolm A. Peirson
Ethylene Cracking Furnace operators are under continuing pressure to increase furnace efficiency. Fuel costs, environmental concerns and reduced maintenance budgets demand that unit reliability and efficiency be kept at a high level. Our paper will discuss an operational problem common to high...

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...

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)...

Compressor Train Performance - Evaluation and Monitoring (Part 2)

Mar 13, 2011
Stephen Plaisance
Utilization of Equipment Health Management system tools has allowed end users to monitor, protect and manage the critical rotating machinery in an Ethylene Plant. This paper will present an equipment health management system architecture, hardware and software components that provide performance...

New Flare System VOC Regulations & Reduction Control Options

Mar 13, 2011
Keith Wade
As this abstract is written, there will be flare system emission testing in a controlled environment underway that will likely pave the way for new VOC control measures on all flare systems in the US. The TCEQ (Texas Commission on Environmental Quality) sponsored testing held in Q4 2010, will...

Centrifugal Process Compressors - the Basics of Performance and Rerate

Mar 13, 2011
Colman de Jong
This work provides a brief overview of the thermodynamics of centrifugal compressor performance. A discussion of what terms are used to describe compressor performance, how is performance calculated and predicted, how the fan laws can be used to predict compressor performance, and how is this...

Fundamentals of Alarm Management

Mar 13, 2011
Peter G. Herena
When the information era began thirty years ago, the focus for the refinery control specialist was placing as much data as possible into the hands of engineers and operators. The philosophy remained prevalent though the volume of transferred data leaped by orders of magnitude every decade...
