Operational Inputs Into the Mechanical Integrity Program

Mar 15, 2011
F. Russ Davis
A predictive mechanical integrity (MI) program is based on the following: * Damage mechanisms that affect process equipment. * Rate at which degradation progresses. * Ability of the inspection group to identify and correct equipment damage before equipment failure. Operational temperature, pressure...

Practices to Mitigate NOx Risk In Cryogenic Section of Ethylene Plants

Mar 15, 2011
Jennifer L. Bancroft
In May 2010 the Ethylene Producers Committee NOx Safety Sub-Committee sponsored a discussion on practices to mitigate NOx risk in the cryogenic section of ethylene plants. The meeting was attended by representatives of 10 ethylene producers, 4 ethylene contractors and other contractors, 2 additive...

Advanced Hydrogen Management : More Than a Balancing Act

Mar 15, 2011
Sanjiv Ratan
Modern high complexity refining landscape involves increasing proportion of “opportunity crude” processing and widened bottom-of-the-barrel strategies, which together with ever stringent ‘clean fuels’ requirements has led to extensive need for hydrogen and its optimization in the refinery. This in...

Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology

Mar 15, 2011
P. N. Ramaswamy
Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology It is widely known that there is a potential for fouling in Cracked Gas Compressors within Ethylene plants. Gas crackers have generally had a higher fouling potential than liquid crackers due to the lack of aromatic...

Thoughts about Safety, Staying at Zero

Mar 15, 2011
Rendell Newton
Perfect safety records and perfect environmental records are an “inalienable right”, given to us not by governments, companies, or others. It is a right we give ourselves. It takes different skills and thinking to stay at zero recordable incidents than it does to get to zero recordable incidents...

Inferential Monitoring & Optimization of Crude Units Via Hybrid Models

Mar 15, 2011
Vladimir Mahalec
Refinery crude units often process variety of feedstocks. If properties of the feed entering the crude unit are not precisely known, it is difficult to predict how changes in the tower operating conditions will affect properties of the products. Similarly, if on-line analyzers are not available, it...

Flare Minimization Via Dynamic Simulation

Mar 15, 2011
Kuyen Li
Flaring in chemical process industry (CPI) is an important method to protect equipment and personnel safety during the process upset and the chemical plant turnaround. However, excessive flaring emits lots of carbon dioxide as well as air pollutants, which cause negative environmental and social...
