Project management can be a messy, complex issue for all involved parties and, likely, the most hair-raising aspect of all is project handover from the EPC (engineering, procurement, construction) contractor to the chemical processor. In the past, this literally involved a truck pulling up with cartons and boxes chock full of engineering documents, drawings, operations manuals and catalogs. From there, the...

  The current economic recession has hit trade show attendance especially hard. A number of events for 2009 have been cancelled, while others are implementing contingencies. Discounted registration fees are common, while at least one event offered to cover attendees airfare before finally deciding to postpone altogether. Some of the more resilient organizations are offering the alternative of live...

With the exception of Oslo-type crystallizers, the main commercial crystallizers are agitated systems that use an agitator [agitated tank or draft-tube baffle (DTB)] or a circulation pump [forced circulation (FC) crystallizers]. In such systems, however, large crystals become damaged by the pump or impeller, which leads to the generation of fines, says Michel Malfand, president of Crystal Evap consult...

Many methods have been developed for the encapsulation of "active" materials within a carrier nanoparticle, such as a polymer. These composite structures can be used in many biomedical, cosmetics, and food processing applications for the controlled release of pharmaceuticals, neutraceuticals, and flavors. However, most of the proposed encapsulation methods developed so far involve multiple steps...

Aqueous Recovery Resources, Inc. (ARR; Bedford Hill, NY; www.suparator.com), has developed the Suparator, an oil/water separation system that involves no moving parts or media, for low operational costs and minimal maintenance. The separator (diagram) is based on the Bernoulli effect, whereby increased stream velocity in a fluid results in internal pressure reduction, which enables liquids of different...

The American Society of Testing Materials (Conshohocken, Pa.; www.astm.org) has developed a new standard for measuring viscosity: ASTM D 7483-08, Determination of Dynamic and Kinematic Viscosity of Liquids by Oscillating Piston Viscometer (OPV). The new ASTM method is part of a brand new product line to be launched this month by Cambridge Viscosity (Medford, Mass.; www.cambridgeviscosity.com). OPVs are...

Primary amines are made in high yield by a palladium-catalyzed allylic amination reaction developed by Shu Kobayashi, a chemistry professor at the University of Tokyo (Japan; www.chem.s.u-tokyo.ac.jp.). The reaction uses aqueous ammonia as the nitrogen source — the first time this has ever been achieved, disproving a 30-year old theory that allylic...

Calibration-free pH The world’s first continuously self-calibrating pH measurement system was previewed at the Interphex show in New York last month by Sensorin (Burlingame, Calif; www.sensorin.com). According to the manufacturer, all currently available pH sensors including glass, optical and ion-selective field effect transistors (ISFET) require calibration, whereas Sensorin’s approach, which...

Nearly 30 years ago (May 6, 1979), U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: "In the year 2000, the solar heater behind me will still be here, supplying cheap, efficient energy. A generation from now, this solar heater can either be a curiosity, a museum piece, an example of a road not...

Despite various studies and process automation supplier suggestions that wireless sensing technologies cost less and provide tighter control than their wired counterparts, chemical processors are still proceeding with caution when it comes to implementing wireless instrumentation. Wireless supporters hope the introduction of WirelessHART and the eventual publication of ISA 100 will help break down the...

A process that produces hydrogen from coal with close to 80% energy conversion efficiency, plus coproduction of a carbon-dioxide-rich stream for sequestration, is being developed at Ohio State University (Columbus, Ohio; www.osu.edu). This compares with around 60% conversion efficiency for traditional coal gasification processes, says Fanxing Li, a research associate and co-inventor of the process along...

A less-expensive way of making the raw materials for carbon anodes (for aluminum smelting) and graphite electrodes (used to make steel in electric arc furnaces) has been developed by West Virginia University (UWV; Morgantown, W.Va.; www.wvu.edu). The conventional starting materials for making electrodes are needle-grade coke (from petroleum) and binder pitch, which comes from petroleum distillation residue...

Milkweed, a plant that is toxic to farm animals and other creatures, may be a future source of a base material for sunscreen and other skin care products. Milkweed is harvested for floss, used as a hypoallergenic filler for pillows and comforters, and a byproduct of that work is an unsaturated oil. A process that converts triglycerides in that oil to ultraviolet- (UV)...
