Release Scenario Assumptions for Modeling Risk From Underground Gaseous Pipelines

May 1, 2013
Elizabeth Lutostansky, Joan Schork, Keith Ludwig, Leonard Creitz, Seungho Jung
Underground pipelines transport toxic and/or flammable pressurized gases in close proximity to residential and commercial areas and highways. The quantified risk assessment of these pipelines is dependent on release scenarios, assumed frequencies, weather probabilities, neighboring populations, etc...

Visual Aid to Reduce Spurious Trips and Nuisance Alarms

May 1, 2013
Fareed Ebrahim, Patrick Fisher
HAZOP and Safety Integrity Level (SIL studies encourage adding safeguards such as alarms and trip with little consideration for cost or operability of the plant once it is running. This results in processes that cannot be operated without bypassing a large number of the interlocks, and important...

Small Site MOC: Big Company Challenges without Big Company Resources

May 1, 2013
Rainer Hoff
Many have argued that the PSM regulations impact small sites particularly hard. While small sites must comply with the same regulations as much larger sites, small sites are hamstrung by a lack of resources. This is particularly true for Management of Change due to the inherent complexity of MOC...

Update of the Activities of the NOx Safety Task Group

May 1, 2013
Dane Grenoble
The initial AIChE Task Group for NOx Safety was set up following a disclosure of significant accumulations of the NOx compound, N 2 O 3, in an ethylene cold box located at a plant on the Gulf Coast. Twenty-five years ago they issued their report describing the potential risks from the accumulation...

Preventing Process Safety Problems of Tomorrow, Today!

May 1, 2013
Kevin Watson, Robert Dayton
The most cost effective time for implementing process safety design elements is during the planning stages of the project management process. Gap: Facilities are designed with less than adequate process safety considerations and the gap is discovered after the facilities are constructed. Addressing...

Hydrogen Generation From Residuum

May 1, 2013
Girish Srinivas, Jeff Martin, Robert Copeland, Steven Gebhard
Refineries in the U.S. are processing increasingly heavy sour crudes that contain metals, sulfur, and high molecular weight aromatic hydrocarbons. Many sour crude oils originate in the Western Hemisphere, including heavy crudes from Venezuela, southern California, and the oil sands in Canada...

MAPD Stability and Management in Ethylene Plants

May 1, 2013
Jeff Melching, Peter E. Feld
Abstract MAPD Stability and Management in Ethylene Plants Accumulation of C3 (MAPD, Methyl Acetylene & Propadiene) and C4 (VA, Vinyl Acetylene) acetylenes to high concentrations has been known as a potential hazard in ethylene and butadiene plant operation. These components are heat and shock...

Tunable Polyimide and Resulting Carbon Molecular Sieve Membranes for Gas Separation

May 1, 2013
William J. Koros, Wulin Qiu
Polymer membranes have been used for natural gas and olefin-paraffin gases separations successfully. However, the separation performance is limited by a productivity and efficiency trade-off upper bound. Therefore, advanced carbon molecular sieves (CMS) materials were developed. These materials...
