Process Modeling : New HSC Chemistry 6.0

Espoo, Finland -- Outokumpu Technology has just released a new version of the renowned HSC Chemistry® process calculation software which enables the user to simulate the whole chemical or physical process. The new HSC Chemistry® 6.0 contains 21 calculation modules and 11 databases for reaction, equilibrium, heat balance, heat transfer, petrological and simulation applications. The extensive thermochemical database has also been expanded to include over 20,000 species.

A Great Step forward for Green Chemistry

The rapid increase in the standard of living in the developing world means that more and more natural resources are required. Consequently we need new technology and better scientific tools in order to conserve the diversity and beauty of nature, and to simultaneously allow increased consumption by large population groups in all nations.

The new HSC flowsheet simulation module makes it possible to optimize process output and minimize waste materials, identify metering errors and improve the understanding of process interdependencies. HSC may be used to rapidly focus expensive experimental research towards ideal process conditions, for example, in chemistry, metallurgy, mineral processing, energy production and many other areas of industry.

The HSC flowsheet enables the pre-test simulation of the effect of recycling streams, raw materials and different operating conditions on process efficiency and emissions, all on a desktop computer without needing to disrupt the actual process. In short, HSC may be used to convert hazardous waste materials into valuable raw materials.

32 Years of Experience

HSC Chemistry was originally developed for Outokumpu Technology as an in-house tool. This work started back in 1974, when equilibrium compositions of sulfur plant flue gases had to be estimated. Since then, new calculation modules and databases have been developed according to the needs of hundreds of different research projects. A large number of experts, programmers and university students have participated in the software development and database compilation work within the last 32 years.

The development of the new flowsheet simulation modules started in 2002, more than 30 process simulation models have already been created using the new flowsheet simulation module before this Autumn's release of the latest HSC version to the public.

Pricing and Availability

The HSC 6 license is available from the Outokumpu Technology Web site for a price of 1190 Euros. HSC 6 is an invaluable tool for any process engineer or scientist because one laboratory experiment may cost much more than a single HSC license.

US Packaging Machinery Exports Strengthen

Arlington, VA -- United States exports of packaging machinery are up 7 percent from one year ago totaling US $646 million. The data, based on the U.S. Census estimates and reported by the Packaging Machinery Manufacturers Institute (PMMI) indicates that U.S. exports of packaging machinery are poised to surpass the $1 billion mark for the third consecutive year.

“The recent U.S. Census report is good news for PMMI members, the global consumer and industrial goods marketplace, where a ‘total system’ approach is required to meet today’s production demands,” said Charles D. Yuska, president and CEO, PMMI. “PMMI members have a global reputation for producing flexible, cost-effective and safe packaging machinery, and the marketplace is clearly responding.”

Domestic sales of packaging machinery also indicate the economic strength of the industry. Earlier this year, PMMI reported that U.S. packaging machinery sales within the United States are predicted to grow 3% to an estimated $5.854 billion in 2006, marking the fifth consecutive year of growth, according to PMMI’s U.S. Purchasing Plans Study.

Packaging is a critical component of all branding, merchandising and promotional strategies. Brand owners rely on product packaging to gain a competitive advantage in the local, national and global marketplace. Packaging machinery manufacturers transform packaging concepts into tangible products. Machinery design and capabilities continue to advance helping speed a product’s time-to-market.

About PMMI

Founded in 1933, the Packaging Machinery Manufacturers Institute (PMMI) is the leading global resource and trade association for the packaging industry. PMMI’s membership has grown to more than 500 members who manufacture packaging and packaging-related converting machinery and twenty three supplier members who manufacture commercially available packaging machinery components in the United States and Canada.

PMMI members are globally renowned for making the highest quality equipment, offering responsive service and committing to meeting their customers’ needs. More than one out of every four machines sold around the world is made by a PMMI member company.

Temcor Replaces Dome for Cement Plant

GARDENA, CA -- Temcor, the world’s largest Aluminum Dome builder has just completed the construction of a 135m Temcor Aluminum Dome for the Taiwan Cement Corporation (TCC). The dome replaces a previous structure destroyed by a typhoon. The new dome is currently the world’s largest clear-span aluminum dome.

The original dome, built by another manufacturer in 1997, covered a limestone blending pile at Taiwan Cement Corporation’s Ho-Ping Cement Plant. In July of 2005, the dome was destroyed by a seasonal typhoon. Temcor, a company which has bulk storage domes in place throughout Asia and the world, was awarded the contract in January 2006 to replace the failed dome, with a very important caveat: the limestone handling system needed to stay partially in service during the construction of the new dome.

Temcor designed, engineered and manufactured the dome in the U.S. and shipped it, ready-to-assemble, to the cement plant. In the meantime, TCC modified the existing support walls in preparation for the new dome.

To accommodate this requirement, Temcor developed a custom erection system to install the dome while the plant continued to operate. Temcor modified its unique Center Tower Erection method, where the erection tower is built up and used to assemble the dome from the center, out. As each strut ring is complete, the tower raises the dome to allow workers to continue on the next ring while working safely at ground level.

At Ho-Ping, a 30m high temporary steel frame was built around the stacking equipment’s center column to just above the incoming conveyor, to which Temcor mounted their traditional center tower for a total tower height of 84m. to facilitate the dome’s erection, the plant’s reclaimer system was moved to the side, and a diversion chute was implemented to divert the incoming limestone from the conveyor to the underground reclaim tunnel’s conveyor.

The dome design includes 18 skylights, two truck doors and three gravity vents.

Construction began in late June and will be completed in less than 20 weeks – even though the bulk of the work was done during typhoon season. Temcor took extra protective measures to ensure that construction could progress uninterrupted. And while several typhoons came through the area during construction, none hit the plant directly.

The new dome at Ho-Ping is made entirely of aluminum and will continue to be maintenance- and corrosion-free for years to come. It was designed to withstand wind speeds of 65m/s, 3-second average.

Feeder Eliminates Costly "No Flow" Events

Broomall, PA -- When wet coal is prevalent, ordinary feeders often become clogged, causing pluggage and inadequate flow to the pulverizers. This causes fluctuations in boiler heat rate, sometimes requiring the boiler to come off line until the problem is corrected. The Posimetric® Feeder can eliminate these costly "no coal flow" events.

Pennsylvania Crusher's Posimetric Feeder reliably handles materials having an extraordinary range of characteristics, including wet, dry, lumpy, sticky, abrasive or granular. Practically immune to jams, it feeds with a consistency that ordinary feeders cannot attain, and it feeds with no surges and no partial feeding.

The Posimetric feeder is a self-cleaning, positive displacement device with only one moving part, a closed, circular chamber with openings at its input and output points. Material enters, continuously locks up within the chamber and is carried to the discharge point at a constant rate, much like a rope travels around a pulley. Slow rotation speed, freedom from jams, and minimal wear help this model to rank among the most trouble-free items in a plant.

Mr. Measor wants help conveying flour vertically:

We are looking into options to elevate flour about 1 cubic foot a minute to two bins about 14 ft apart. The rise is about 20 feet and real estate says this must be vertical or near vertical.

We have had dense phase pneumatic suggested. But as I understand DP the vertical run would plug? True?

Alternatives? Possibly cable & discs in pipe? or.. Most solutions are way too big for this limited flow. (to post reply, click here)

Mr. Grigore needs to unload iron ore from railcars:

I'm looking for a system to unloading railcars, bottom dumping, in motion at 3,500 mt/hr. The material is iron ore of 140#/cu.ft.  In my opinion, the complete system has to include the following items:

- long hopper in order to empty each wagon
- rotary plow feeders under the hopper
- a belt conveyor under the plow feeders
- a system that will open automatically the bottom gates of the cars.

Any ideas or manufacturer references will be appreciated.
