Property Insurance Company Evaluation of Combustible Dust Hazards

Mar 22, 2010
Henry L. Febo
This paper will discuss some of the key factors that FM Global insurance engineering representatives use in evaluating combustible dust hazards at insured locations. The information is used to develop underwriting information but more importantly, it is the basis for guidance provided for the...

How to Evaluate Process Safety Culture

Mar 22, 2010
Jerry Forest
At first glance it may seem that organizational culture is subjective and therefore difficult to measure. Indeed, even the definition of culture falls into the soft side of process safety. This paper will show that an objective approach can be taken to survey and define process safety culture. With...

An Operator Training Simulator (OTS) for a SUPERFLEX(TM) Unit

Mar 22, 2010
Ravi Guddeti
An Operator Training Simulator (OTS) of a new SUPERFLEXTM unit has been designed and built to provide highly realistic process and operations training to operators of a first of a kind petrochemicals plant. The OTS, which was delivered to Sasol in 2005, and otherwise called the Sasol Superflex OTS...

Advanced Materials for Radiant Coils

Mar 22, 2010
Dr. Deitlinde Jakobi
Since radiant coils operate under severe conditions of carburization, oxidation and erosion tube material selection plays an important role. Schmidt + Clemens and the R&D-institute HDZ have developed a new bench-scale unit to simulate high temperature corrosion of alloys in petrochemical plants...

Advances in Renewable Jet Technology

Mar 22, 2010
Use of aviation fuel currently corresponds to 2-3% of the total fossil fuels used worldwide, or 13% of fossil fuel used in transportation fuel. Aviation fuel use is the second biggest sector after road transportation, which consumes 80 percent. Further, the aviation industry is expecting to grow at...

Results of Root Cause Analyses of Spring Operated Pressure Relief Valve Failures

Mar 22, 2010
Julia V. Bukowski
A subset of 44 failed spring operated pressure relief valves (SORV) from a set of over 5600 Process Equipment Reliability Database (PERD) proof tests was subjected to root cause of failure analysis (RCA). This paper reports on the findings of those 44 analyses and includes specific examples of root...

Process Safety in the Face of Significant Change

Mar 22, 2010
Leslie J. May
Development of an effective process safety culture requires employees to look beyond intended performance, to their own nonconscious assumptions about process safety. When firmly in place, effective process safety culture instills an environment where employees differentiate between events which,...

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-...

Cracked Gas Dryer Tutorial (Part 2)

Mar 22, 2010
Bruno De Jonckheere
This tutorial will begin with a brief introduction to molecular sieves followed by a description of the process, covering overall operation of the charge gas dryer including adsorption and regeneration steps. Key design considerations will be discussed along with optimization and troubleshooting...

Advances in LNG Expander Technology

Mar 22, 2010
Joel Madison
The first use of cryogenic liquefied gas expanders dates back to the late nineties. The proven advantages of incorporating liquid expanders in the LNG liquefaction process lead the way to equip every new liquefaction plant with LNG expanders. The basic design concept of cryogenic expanders has...
