AIChE Spring Meeting and Global Congress on Process Safety

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...

Natural Gas Liquid (NGL) separation is an important link in any LNG plant. Recently, expander-based process has received increased attention, thanks to better appreciation of the refrigeration integration between NGL and LNG sections. SIMAR, which stands for System Intrinsic Maximum Recovery, is a...

Magnetic bearings in turboexpander have become the standard for the installation in gas processing and ethylene plants; there are areas of the design that are challenging to the designer for each application. This paper begins with a review of magnetic bearings, the components and how they operate...

Today's ethylene plants incorporate Turboexpander Systems in order to optimize cryogenic recovery and energy demand. The related residue gas molecular weight and flow rates depend directly upon the selected upstream feedstock gas composition, conversion, and feedrates. Various recent ethylene units...

Many issues face coal fired utilities with respect to environmental demands, some based on regulations and others based on local pressures. These include increasingly stringent control of criteria pollutants, anticipated federal and state requirements for mercury control, issues revolving around...

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...

The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be released in the flue gas. Trace...

Recent upward trends in energy costs combined with focus on emissions of greenhouse gases has led both engineering design companies and operating companies to consider methods to optimize energy consumption of olefins units, including emphasis on the pyrolysis furnaces, compressor/turbine sets,...

In today’s competitive environment, development and implementation of new refining technology can differentiate one refining company from another. Whether in processing non-traditional crudes such as oil/tar sands or high sulfur crudes, extracting more from the bottom of the barrel, complying with...

Papers are on topics related sustatinable supply of a wide variety of biomass feedstocks to meet the needs of evolving liquid fuel demand (transportation and heating) and alternative enrgy sources. Please Note : Biomass Thermal Conversion -- Spring Meeting 2009 includes the following recorded...
