Progression of GHG Emissions Benchmarking

Mar 21, 2010

Claire Cagnolatti

The efforts to measure, regulate, and control the emissions of greenhouse gases (GHG) by the refining and petrochemicals industries have been in effect in varying degrees in several countries and regions around the world. Companies that operate such facilities in regions with pending or active...

Impact of Pressure Recovery on C2 Recovery Processes – Comparing Performances Between Expander and JT Valves

Mar 21, 2010

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...

Impact of Feedstock Variations on the Performance of Multi-Component Refrigeration Compressors

Mar 21, 2010

Satoshi Hata

Conventional ethylene technology uses three separate refrigeration compressor systems. Lummus has developed a patented mixed refrigeration system that provides the refrigeration needs from ambient to -140°C. Based on the inherent process flexibility with respect to feedstock variations, a...

Qualitative Prediction of Sorbent Performance for Mercury Capture by Lab-Scale Tests

Mar 21, 2010

Evan J. Granite

It would be desirable to have a simple and inexpensive test for predicting sorbent performance for mercury capture in coal-burning power plants and in integrated gasification-combined cycle (IGCC) facilities. Several lab-scale packed bed reactors have been employed to screen sorbents for 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...

Technology and Rotating Contributions / Combinations . TurboExpander - Recompressors

Mar 21, 2010

Kara R. Byrne

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...
