Reboiler Circuit Debottleneck with No Hardware Changes
With a thorough investigation and proper problem diagnosis, an entire gas plant limited by a deethanizer reboiler circuit was successfully debottlenecked This article describes a case study of a gas plant (designed by others) that was bottlenecked by the reboil…
Chementator briefs
Desalination Recently, Formosa Petrochemical Corp. (FPCC; Mailiao, Taiwan; www.fpcc.com.tw) commissioned IDE Technologies (Kadima, Israel; www.ide-tech.com) to build a desalination plant in Yunlin County, Taiwan that will be the first large-scale application for IDE’s high-purity boron-removal process. The three-step process combines…
A probe that tests galvanizing kettles at high temperatures
To provide corrosion protection and long life, steel products are galvanized by immersion into kettles containing molten zinc. These galvanizing kettles need to be checked periodically to monitor rates of corrosion in order to avoid a catastrophic spillage of molten…
A new zeolite catalyst promises to significantly improve naphtha cracking
Chiyoda Corp. (Yokohama, www.chiyoda-corp.com) has been working on a new naphtha cracking process with the aim of producing more propylene and consuming less energy than existing naphtha thermal-cracking methods. The company has recently developed a new catalyst based on iron-…
A ‘greener’ more sustainable route to trimethylgallium
Last month, the Precious Metals Chemistry business unit of Umicore AG & Co. KG (Hanau-Wolfgang, Germany; www.pmc.umicore.com) inaugurated its production unit for making trimethylgallium (TMGa) and triethylgallium (TEGa). The new facility uses a new, patented production process to make these…
A new catalyst for making methane from CO2 and H2
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…
Make more from biomass with iron
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…
New process generates salable products from Marcellus produced water
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.…
Bio-based xylitol lowers production costs
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…
