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...

The Extended History of PRICAT(TM) 468 for C4 Acetylene Hydrogenation

South Texas Section Webinar
May 5, 2011
Gary Gildert

Step three of the 'Eight Steps to Specify a Catalyst Bed' is selecting the catalyst. The process of developing and selecting catalysts is often shrouded in mystery. Examining the history of a product development can demystify the process.

Loss of Downcomer Seal on a Depropanizer During a Plant Start up

Mar 16, 2011
Andre Bernard
The bottom C4’s product specification could not be met on the Depropanizer tower during a plant start up. The olefins unit had been started with a new start up procedure, which involved significant reduction in feed rates to the unit until achieving on spec ethylene. C3 & C4’s product were to...

Improved Ethylene Cracking Furnace Control with Modern Process Mass Spectrometers

Mar 16, 2011
Peter J. Traynor
Whereas process mass spectrometers have been used as an alternative (lower cost) solution to multiple process gas chromatograph installations for many years, their use has been somewhat limited by their complexity - both real and perceived. The latest generation of process mass spectrometers has...

A New Class of Polymer Inhibitors

Mar 16, 2011
P. N. Ramaswamy
Polymer inhibitors are used within an ethylene plant in locations which are susceptible to aggressive polymer formation i.e. Primary Fractionator, Compressors, Pyrolysis Gasoline Strippers and within the Gas Separation units. Over the years, the use of such additives has been extended to newer...

More Refinery H2 through Efficiency, Recovery, and Process Improvements

Mar 15, 2011
Alan Zagoria
Hydrogen is even more important to refiners than it was just a few years ago. Heavier crudes, clean fuels, and increased conversion have increased hydrogen demand. Refiners can face costly choices if forced to adjust refinery operations to respond to hydrogen availability constraints. It is...

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...

Increased Fouling Potential and Mitigation Plans for Heavy Sour Crude Oils

Mar 15, 2011
Parag Shah
It is becoming a widespread norm that refineries are processing an increasing quantity of heavy and sour crudes than ever before. The depleting oil reserves of light sweet crudes have resulted in the need for deeper exploration. Considerable finds in the Orinoco belt of Venezuela, California and...

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...
