Tutorial: The Chemistry of Refinery Fouling

Apr 2, 2012
Irv Wiehe
The chemistry of refinery fouling is well enough understood to mitigate nearly all fouling. The key information required are the location of the foulant, elemental analysis of the foulant, and identification of precursors in the oil flowing through the fouled unit. Most organic fouling is caused by...

Dynamic Simulation of Demethanizer and Chilling Train System

Apr 2, 2012
Shujing Zhang
The chilling train system is an important part of ethylene plant which is usually combined with demethanizer and a series of flash drums to separate hydrogen and methane from cracked gas, and recover the hydrogen and methane as different products through multi-stream heat transfer with refrigerants...

Implementation of a Highly Toxic Materials Management Program

Apr 2, 2012
Ravi Ramaswamy
Process Safety Management (PSM) is defined as the application of management systems and controls (programs, procedures, audits, evaluations) to a manufacturing or chemical process in a way that process hazards are identified, understood, and controlled so that process-related injuries and incidents...

Maximizing LNG Capacity for Liquefaction Processes Utilizing Electric Motors

Apr 2, 2012
Jonathan Berg
In some locations currently being considered for LNG projects, relatively low cost electricity from the local power grid may be available. For these facilities, refrigeration compressors driven by electric motors drawing power from the grid may be attractive. The fuel requirements for these plants...

ìWell the Team Has Met and Completed the PHAÖ.Now What?î

Dewana Tarpley
Learning from the experiences and expertise of others has long been recognized as a valued process when completing PHAs. The gathering of a multi-disciplinary review allows facilities to succeed in a path of continuous improvement by evaluating the current and future state of the process based on...

Global and Local QSPR Models to Predict the Impact Sensitivity of Nitro Compounds

Apr 2, 2012
Guillaume Fayet
New quantitative structure property relationships (QSPR) have been developed to predict accurately the impact sensitivity of nitro compounds from their molecular structures. Such predictive approaches represent good alternative to complete experimental testing in development process or for...

The US Chemical Safety Board and Inherently Safer Technology

Apr 2, 2012
Manuel R. Gomez
The United State (US) Chemical Safety Board (CSB) was created by the same legislation that mandated the regulation of high hazard industries by the Occupational Safety and Health Administration (OSHA) and Environmental Protection Agency (EPA) under the Process Safety Management (PSM) and the Risk...

Performance, Maintenance and Environmental Benefits of An Integral SCR

Apr 2, 2012
Stephen De Haan
Selective Catalytic Reduction (SCR) involves injecting a NOx reducing chemical, such as aqueous ammonia, into the an exhaust stream in the presence of a catalyst within a specific temperature window of approximately 650°F to 1100°F. To reduce NOx emissions from an ethylene cracker, Chevron Phillips...
