Chem Economics: ACC Releases Portfolio of Specialty Chemicals Indexes

September
2012
Chem Economics
T. Kevin Swift
The American Chemistry Council (ACC) has launched a new set of indexes covering nearly 30 segments of the U.S. specialty chemicals market. (The first, which dealt with plastic additives, was discussed in the July issue, p. 13.) This is the first set...

Edward Cussler

This webinar will discuss whether the skill set of chemists and chemical engineers is appropriate for this altered chemical industry.

Galvanic Corrosion Between Dissimilar Metals

Apr 5, 2012
Richard Rolke
A Dow USGC cracker suffered a tube failure on a cracked gas compressor inner stage cooler after ten plus years of service. To further extend the equipment life, the decision was made to replace the tube bundle and upgrade the metallurgy of the tubes from admiralty brass to Duplex stainless steel...

Modeling of LNG Spills Into Trenches and Troughs

Apr 5, 2012
Nicolas F. Ponchaut
Trenches and troughs are commonly used in LNG storage and transfer facilities to contain potential LNG spills. The trenches are concrete-lined rectangular channels dug into the ground. They are typically slightly inclined from the horizontal to direct the flow of LNG towards the sump and they are...

Hydroprocessing Design - Tutorial

Apr 4, 2012
Stuart Shih
Hydroprocessing or hydrotreating is the key technology to clean, to refine, and to convert crude oils into valuable products, such as gasoline and diesel. It covers a wide range of feed stocks and numerous configurations. The tutorial will discuss process configuration, material selection, and heat...

Anti-Surge Methods for the Base Load LNG Plant Propane Compressor

Apr 4, 2012
J. C. Kuo
The propane compressor represents a significant capital investment and operating expense of a LNG plant, and is an essential component in providing revenue streams of the plant. Therefore, operation and protection of the propane compressor are critical issues in the plant design and operation. The...

Guidelines for Jetting and Flashing LNG Vapor Exclusion Zone Analysis

Apr 4, 2012
Delmar R. Morrison
Liquefied Natural Gas (LNG) has been a growing energy resource in the U.S., for which significant import and storage infrastructure was developed in the past decade. The infrastructure for liquefaction and export has also been developing as a result of recent shale gas finds in North America. In...

Tutorial on Hydroprocessing: ìHydroprocessing Catalysts and Processesî

Apr 4, 2012
Paul Robinson
The products of petroleum refining must meet tight specifications, including limits on sulfur, nitrogen, olefins, aromatics, and other contaminants. Hydrotreating removes these contaminants from distilled crude oil fractions and intermediate process streams. Hydrocracking converts heavy oil...

Cost Effectiveness of 2-Row Membrane System for FLNG

Apr 3, 2012
Herbert Moon
One of the most critical issues in engineering and design of FLNG is to reduce top side weight along with its load distribution to the sub-structure. Concentrated top side loads will result in an increase in hull structure costs. The developed 2-row containment system allows flexibility of top side...

ABSTRACT A Liquefied Natural Gas (LNG) plant demands a large amount of mechanical power for generating...

Fate of Ammonia in Refinery Amine Systems

Apr 2, 2012
Nathan A. Hatcher
Fate of Ammonia in Refinery Amine Systems Ralph H. Weiland, Nathan A. Hatcher & R. Scott Alvis Optimized Gas Treating, Inc. Sugar Land, TX ABSTRACT Ammonia ingress and accumulation in refinery and bio-gas amine systems is not a new problem. However, increasing utilization of advantaged crudes...

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...

Waste Heat Recovery Considerations in LNG Plants

Apr 2, 2012
Douglas Wiles
WASTE HEAT RECOVERY CONSIDERATIONS IN LNG PLANTS ABSTRACT DOUGLAS WILES, RYAN HOLLENBACH & STANLEY KWAN Thermal integration in an LNG plant improves its overall thermal efficiency. Thermally integrated plants tend to have lower operating costs and reduced environmental emissions including, CO,...

Combustion of Mixtures: A Modified IFC Approach

Apr 2, 2012
Gary Mueller
While most studies on flares have been done with single hydrocarbon fuels or binary mixtures, the reality of most industrial flares is that they see different mixtures of many gases. Over the past 5 years the International Flare Consortium (IFC) has been conducting research on just this issue. In a...
