The Sabatier reaction, in which H2 and CO2 react at temperatures of 300–400°C in the presence of a nickel catalyst, or an alumina-supported ruthenium catalyst, is one way to reduce CO2 into methane. Until now, however, it has been difficult…
Nippon Shokubai Co. (Osaka and Tokyo, Japan; www.shokubai.co.jp) has jointly developed a new process for biomass utilization in collaboration with professor Yuichi Kita at Kobe University (www.kobe-u.ac.jp). The process is highly efficient for decomposing lignocellulose into a group of water-soluble…
Produced water from natural gas wells in the Marcellus Shale Deposit is extremely high in total dissolved solids (TDS; levels of 25–35% TDS are common) and barium, making the water difficult to re-use and requiring injection in underground geologic formations.…
While demand for the artificial sweetener xylitol grows, expensive raw materials and low yields have kept production prices high. Now, a new process from S2G BioChem (Vancouver, B.C., Canada; www.s2gbiochem.com) aims to produce xylitol in a more cost-effective way, utilizing…
Natural gas vehicles (NGVs) are attractive because of the low cost and wide availability of natural gas, plus the ability to connect to residential and business gas lines for fueling. Among the challenges for using natural gas as a fuel…
Data points from literature are refined into a single correlation defining dry-tray pressure drop in sieve trays The sieve tray has been in the marketplace as a distillation device for many decades. It has been used extensively on distillation tray…
Characterizing mixer impellers on the basis of power, flow, shear and efficiency Mixing has been defined as “the application of mechanical motion in order to create fluid dynamic effects that achieve a desired process result” [1]. The process result is…
Mixing, granulating, coating, drying and heating and cooling can be performed in this company’s “single-pot” process developed for the food industry. The process performs chemical reactions or mechanical product treatment in one machine; several process steps can take place without…
VarioPur (photo) is a new product range that includes three high-performance materials based on thermoplastic polyurethanes (TPU/AU). Both abrasion and extrusion resistance are at least five times higher than those of the traditional material, NBR (nitrile butyl rubber). The three…
The new fillpac bag placer (photo) enables efficient bag filling for materials from the construction, cement, mineral and chemical industries. With its standardized modular design, the fillpac provides numerous setup options. For instance, users can set it up at any…
