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...

Bio-Refinery for the Production of Ethylene Derivatives

Mar 22, 2010
Michael Bruscino
Downstream products of petroleum have been the main source for feedstocks for most of the petrochemicals produced over the last 90 years. However, due to the rising price of crude oil and concerns about the environment, there has been a renewed interest in alternative feedstocks, and in particular...

From Biomass to Ethylene: Steam Cracking of Bio-Synfined Naphtha

Mar 22, 2010
Kevin M. Van Geem
The recent high oil prices have focused research attention to alternative routes and feedstocks for the production of light olefins. The former was caused by two reasons: on the one hand the high oil demand from new economies, on the other hand the growing awareness of the declining oil reserves...

Effective Diffusivity Measurement in Coke-Deactivated Hydrotreating Catalyst

Mar 21, 2010
Roberto E. Galiasso Tailleur
The effective diffusivity of two fresh and two spent catalysts, previously deactivated for 18 months in a commercial unit, were determined. The effective diffusivities were measured using a shallow-bed reactor already developed for this purpose. Nitrogen, isopentane and isooctane effective...

Maintaining MPC Benefits for Years: No Myth

Mar 21, 2010
MPC software companies and their customers can sustain and increase the benefits from MPC solutions by forming effective maintenance strategies. This can mean maintaining MPC models current and migrating applications with evolving techniques. This paper will show how a well-formed maintenance...

Elements of Two-Stage Unicracking for Maximum Distillate Production

Mar 21, 2010
Diesel fuel is projected to be one of the strongest market growth transportation fuels over the next ten years. Availability of more heavy and sour crudes, utilization of refinery configurations for maximum distillate production and more stringent diesel fuel specifications are techno-economic...

Tutorial on Using Best Practices to Optimize DP Flow Measurements

Mar 21, 2010
Nathan Stokes
DP Flow is the most frequently applied measurement technology. Uncover the value of re-engineering DP Flow measurement points to enable better measurement. Learn how best practices and innovative designs deliver improved accuracy, reduced maintenance, reduced installed costs, lowered permanent...

Nonlinear Model Order Reduction Using Block Structured Models for Large Processes

Mar 21, 2010
Omar Naeem
Please note: sound does not begin until approximately 30 seconds into the presentation. Typically mathematical models of physical and chemical processes are large and complex because of complications and nonlinearities of physical processes. The importance of mathematical models is evident for...

Environmental Law and Regulation 101

Mar 21, 2010
Chris A. Paul
This presentation will provide a summary of each of the primary environmental regulatory programs, including air, water, waste and emergency planning. These programs are also known by their statutory names, the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act and the Emergency...

Cracked Gas Compressor / Turbine

Mar 21, 2010
Ed Oberthier, Krishna Merchant
The cracked gas compressor (CGC) is still the most critical unit in the entire ethylene production facility. Its energy demand and potential plant run length, linked to its volumetric flow, molecular weight, pressure ratio and associated contaminant removal, is a major design element within the...

Turbomachinery for Mega-Ethylene Plants

Mar 21, 2010
Diane E Scheponik, Donald H. Mansfield
Ethylene producers continue to search for ways to improve capital expenditure versus payback ratio and to reduce installation and maintenance costs by benefitting from economies of scale. As ethylene plant outputs increase beyond the 1 million ton per year size, turbomachinery manufacturers must...

Carbon Capture and Storage - Can CCS Be a Viable Business?

Mar 21, 2010
Ray Hattenbach
Carbon capture and storage (CCS) has been characterized as the technology that can jump start mitigation of greenhouse gases until new, less carbon intensive technology can be implemented to provide electrical power, transportation fuels and energy our society needs to stay competitive in the world...

Simulating a Typical Atmospheric Crude Distillation Unit Tutorial

Mar 21, 2010
David Myers
Atmospheric Crude Columns are one of the most important pieces of equipment in the petroleum refining industry. Typically located after the Desalter and the Crude Furnace, the Atmospheric Tower serves to distil the crude oil into several different cuts. These include naphtha, kerosene, light diesel...

CFD Simulation of Diesel Hydrotreaters Under Periodic Operation Mode

Mar 21, 2010
Middle distillate hydrotreating is the most important refining process for the production of ultra-low-sulfur diesel, in which sulfur content is required to be less than 15 wppm. Hydrotreating is usually conducted in trickle bed hydrotreaters under steady-state operation with constant gas and...
