The Flexstream Gas Standards Generating System dynamically blends calibration gas standards for trace sulfur compounds in food-grade carbon dioxide. Specially designed permeation tubes add low-parts-per-billion (ppb) concentrations of typical sulfur species, including carbonyl sulfide, hydrogen sulfide and mercaptans, directly to…
Last month, Solvay Group (Brussels, Belgium; www.solvay.com) unveiled a methane recovery system (the MaRS Project) that captures methane liberated by mining trona ore (trisodium hydrogendicarbonate dihydrate), and pipes the gas to nearby processing facilities as a fuel for process heating.…
The new CMA series of all-electric modulating actuators are sized for linear, quarter-turn and rotary control valve and pump applications requiring precise position control and continuous modulation. The units can be powered by single-phase or d.c. supplies, eliminating the need…
The Yankuang Group (Zoucheng City, Shandong Province; www.ykjt.cn), one of China’s largest coal companies, and Accelergy Corp. (Houston; www.accelergy.com), are jointly developing a large-scale, low-carbon, coal-to-liquids (CTL) plant incorporating both direct and indirect liquefaction, in Erdos in China’s Inner Mongolia…
This company’s double planetary mixers are now available with a slightly tilted configuration of the stirrers to effect more effective and complete discharge of flowable products. Double planetary mixers are used in the preparation of pastes and gels, as well…
Two dissimilar iron-making methods — a conventional blast furnace using coke from coal, and gas-based direct reduction of iron ore — are combined in a process being developed by Midrex Technologies, Inc. (Charlotte, N.C.; www.midrex.com) and Praxair Inc. (Danbury, Conn.;…
Transfinity elastomer composite products specifically are designed for use in anti-vibration applications. These products provide elastomer compound formulators the flexibility to control damping levels and achieve the highest levels of dynamic durability. This new flexibility in material formulation creates opportunities…
A system that continuously produces 10 ton/yr of nanoparticles has been developed by Tadafumi Adschiri, principal investigator at the Advanced Institute for Materials Research (AIMR) and professor at the Institute of Multidisciplinary Research for Advanced Materials and New Industry Hatchery…
The production rate (per amount of catalyst) for generating liquid hydrocarbons from syngas by the Fischer-Tropsch (F-T) process, using a slurry reactor or tubular reactor, is generally limited to about 30% of the maximum rate. The restraining factor is heat…
Petroleum-derived ethylene normally contains traces of acetylene, which interferes with the conversion of ethylene into polyethylene (PE). Because it is difficult to separate it, the acetylene is selectively hydrogenated to ethylene — without subsequent hydrogenation to ethane — using a…
