Solutions for a Sustainable Tomorrow

Jan 30, 2013
James Porter

This presentation focuses on the critical components of a truly sustainable operation . . . safety, environment, energy, capital management, and asset productivity.

Leadership Is Everyone’s Responsibility

Feb 20, 2013
Greg Shaffer

This webinar discusses the “hidden leadership” opportunities that are woven into everyday roles, how to recognize these opportunities and take advantage of them.

Emissions of Mercury and Other Air Toxics: Compliance Strategies for Coal Combustion

AIChE and A&WMA Web Forum
Jan 23, 2013
Bob Fraser, Constance Senior, Nick Hutson

What do you need to know about mercury, HCI, metals and other toxics control? This webinar will address technical and permitting issues from two perspectives: what is required (by Nick Hutson of USEPA) and what strategies could you adopt (by Bob Fraser of ERM).

Furnace Safe Park DCS Tool

Mar 23, 2010
Bryan McVicker
Properly managing the shutdown or “safe parking” of multiple steam-cracking furnaces during a plant-wide upset can be challenging. Alarm flood and multiple competing demands on operators are characteristics of such situations. The ExxonMobil Beaumont olefins plant has created a DCS interface to...

Uncertainties in Modeling LNG Vapor Dispersion with CFD Codes

Mar 23, 2010
Ruifeng Qi
Computational fluid dynamics (CFD) models have been widely proposed and developed to predict LNG vapor dispersion behavior and to determine safe separation distances around LNG production storage and transportation facilities. This is largely due to the ability of CFD codes to describe fully the...

An Integrated Toolkit for Addressing Human Factors Issues in Process Safety

Mar 23, 2010
David Embrey
This paper describes an integrated toolset, called the Human Factors Workbench, which addresses the proactive and reactive control of human error in process operations. It is a practical application of the tools described in the CCPS publication: ‘Guidelines for Preventing Human Error in Process...

Catastrophic Failure of a Dissimilar Metal Weld in a High Pressure Steam Venturi

Mar 23, 2010
Carl G. Matherne
In mid-2009 at the BASF FINA Petrochemical L.P. Steam Cracker in Port Arthur, Texas, a venturi-type flow meter in super-high-pressure steam service ruptured catastrophically, resulting in a major release of pressure and trip of the plant. Initially a steam leak was observed at the flow meter, and...

Full Potential Conversion of Vacuum Resids

Mar 23, 2010
Irv Wiehe
Present vacuum resid conversion processes, either coking or hydroconversion, are far from achieving their maximum conversion. With the remaining petroleum resources, on average, having a greater fraction of the vacuum resid fraction, it is imperative that new resid conversion processes or schemes...

Enhancing Post-Combustion CO2 Capture in Power Plant – A Catalytic Approach

Mar 23, 2010
Reynolds A. Frimpong
Improved solvent reaction kinetics and carbon capacity continue to be a major research interest for the scrubbing of CO2 in post-combustion processes. The DOE has set a new target for post-combustion CO2 capture of less than a 35% increase in the cost of electricity, while capturing at least 90% of...

Stability Analysis of Safety Valve

Mar 22, 2010
The stability for a safety valve was investigated by experiments and analysis. It was found that the dynamic instability was caused by the interaction effect between the pressure wave propagation through the inlet pipe and the valve disc motion. This dynamic instability is mitigated by the...

Improved Energy Efficiency in CDUs Through Fouling Control

Mar 22, 2010
Jimmy D. Kumana
Crude oil distillation accounts for a large fraction of the energy used in oil refining. Crude oil contains a variety of substances which tend to deposit as fouling layers in heat exchangers, and this results in decreased energy recovery and requires increased energy input to the furnace. CDU pre-...

Strategies & Tactics for Mechanical Integrity Budget Battles

Mar 22, 2010
Daniel A. Long
Effective mechanical integrity programs are essential to assure safe operation of plant facilities. The current economic downturn is difficult and most manufacturing companies have experienced headcount reductions, early retirement programs and budget reductions. Companies are concerned with short...
