Corrosion At Pipe Supports: Causes and Solutions

Apr 30, 2013
Jim Britton, Steve Young
Localized corrosion attack at pipe support areas is a major problem for integrity managers. Offshore, marine and coastal operators, without exception, spend the largest part of their corrosion budgets on paint maintenance due to the damage caused by this type of attack. The inherent design flaws...

What Makes a High-Performing Plant in Solomon's Olefins Studies?

Apr 30, 2013
Claire Cagnolatti
Abstract: What Makes a High-Performing Plant in Solomon’s Olefin Studies? Solomon Associates has conducted studies of the olefins manufacturing industry for nearly 25 years. As part of those studies, Solomon identifies a group of the best-performing plants for every study in each of three feedstock...

Cooling Water Issues Follow up Solutions to Microbiologically Induced Corrosion

Apr 30, 2013
Carl Matherne
In the 2007 turnaround at the BASF TOTAL PETROCHEMICALS LLC Ethylene Steam Cracker, severe damage was discovered in the cooling tower water to process exchangers. Over 40 exchangers had been replaced or required total tube bundle replacement within the first seven years of operation. Several of the...

Exploiting Hydrogen Plant to Improve Refinery Margins

Apr 30, 2013
Sanjiv Ratan
In addressing the global drive for cleaner transport fuels against increasing proportion of heavier and sourer crudes, refiners are faced with the challenge to satisfy their current and future hydrogen demand economically. Hydrogen, with no direct revenue potential of its own, carries a substantial...

Value Additiion by Integrating C3 Derivatives with PDH Units

Apr 30, 2013
Vk Arora
With rapid development of Ethane based Ethylene production in Middle East and switch to lighter feedstock in US crackers have been mainly responsible for shortfall in Propylene and C4s. To fill this gap in Propylene supply, a number of new on-purpose Propylene production units (PDH) are being built...

A Guide to the Legal Framework of the PSM Standard for Engineers

Apr 30, 2013
Christopher Cunio, Georges Melhem
A Guide to the Legal Framework of the Process Safety Management Standard for Engineers By Christopher J. Cunio, Esq. and Georges A. Melhem, Ph.D. The Process Safety Management (PSM) Standard is a U.S. regulation that was issued by the Secretary of Labor in 1992 following a series of chemical...

Gas Cleanup Using Elastic Layered Metal-Organic Framework Adsorbents

Apr 30, 2013
Christian M. Lastoskie, Francisco Sotomayor
The suitability of elastic layered metal-organic frameworks (ELM) for the removal of carbon dioxide from methane-rich gas mixtures was evaluated using molecular modeling and experimental measurements for two adsorbents, ELM-11 [Cu(BF 4 ) 2 (bpy) 2 ] and ELM-12 [Cu(OTf) 2 (bpy) 2 ]. These materials...

Water / Wastewater Optimization Methods for Industrial Systems

Apr 30, 2013
Joseph W Guida
Efficient management of water and wastewater systems in large industrial complexes is important for minimizing costs and optimizing natural resources. This paper provides an overview of methods used to analyze water use efficiency such as water pinch analysis and water cascade analysis as well as...

LNG FSRU and FPSO Pump Considerations for Ship Motion

Apr 30, 2013
Gregory P. Wood
LNG marine pumps installed in FSRU and FPSO applications are exposed to three degrees of ship movement as a result of wave motion. There is concern that adding ship motion to a traditional stationary pump technology can cause issues such as unseating, free spinning, and bearing damage during non...

The Impact of Human Factors On LOPA (and other risk assessment methods)

Apr 30, 2013
William Bridges
All initiating events (IEs) and independent protection layers (IPLs) are inherently tied to human error. Human factors limit the risk reduction values and must be taken into account to ensure true independence of IPLs and to ensure the probability of failure on demand (PFD) of the IPL is achievable...

Worker Behavior Changing by Dynamic Culture

Apr 30, 2013
Salvador vila Filho
INTRODUCTION The chemical industries need appropriated project of process to control safety and production avoiding accidents and environmental impacts. The best project criteria include sufficient information about procedures or activities of operators. The execution is essential to successful...

Troubleshooting a Furnace Emissions Problem

Apr 30, 2013
Greg Dunnells, Jeff Jones
We had been fighting CO flue gas emissions on our CEMS analyzer for around a year, we had indications that it was a burner problem, fixed the burners, not the CO problem, had the vendor in multiple times to look at the burners, did all kinds of tests. Finally, we got our portable analyzer fixed,...

Profitably Recover Ngls, Hydrogen and Ethylene/Propylene From Refinery Fuel Gas

Apr 30, 2013
Benjamin Klein, Guang Lee, Jie Yu, Sudhir Golikeri
Over decades of operation, refinery fuel gas systems have become the repository for purge gases from Fluidized Catalytic Cracking, Delayed Coking, Catalytic Reforming, Hydrotreating and Hydrocracking process units. Flare gas recovery systems also contribute to the build-up of non-methane components...

Explosibility of Nano-Sized Metal Powders
