Honeywell and Environ join forces to promote circular plastic economy in Egypt
Honeywell International Inc. (Charlotte, N.C.) has signed a Memorandum of Understanding (MoU) with Egypt’s Environ Adapt for Recycling Industries with the aim of advancing plastics recycling in the country. The two organizations will explore the development of the first chemical recycling facility…
Better stress distribution with this tool design
This company’s Wright Drive 2.0 socket design is said to distribute contact stress more effectively than other wrench systems. The Wright Drive 2.0 12-point design has up to 10 times more tool-to-fastener contact area than conventional 12-point wrenches. The design…
Using ‘coke’ to reduce CO2 emissions from steelmaking
Liberty Steel UK (LSUK; London; www.libertysteelgroup.com) has completed trials of ecoke — a sustainable new raw material that can replace anthracite, the main source of charge carbon used in the electric-arc furnace (EAF) of steelmaking, and reduce steel’s carbon footprint…
New smelting furnace enables the use of lower-grade ore in DRI ironmaking
In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
Level Measurement & Control
A new level detector for multiphase applications Multiphase level measurements exist throughout chemical process industries (CPI). They are especially significant in the oil-and-gas and petrochemical sectors due to the value derived from effectively separating water and hydrocarbons. While level instrumentation…
Chem Chronicles: Discovery and Re-discovery of Mechanochemistry
A reclusive expert of 19th-century photography laid the foundation for mechanochemistry, a once-ignored field that is re-emerging in ‘green chemistry’ applications For decades in the late 1800s, Carey Lea had been fascinated by the chemistry of photography, and had studied…
New Applications for Spiral-Tube Heat Exchangers
A decades-old, yet less well-known type of heat exchanger offers advantages for new and emerging applications Spiral-tube or helically-coiled heat exchangers have been around for decades addressing sample cooling, mechanical seal cooling, vent condensers, vaporization and general heating or cooling…
Scaling Up Hydrogenation Processes for Biomass Conversion
When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
Facts At Your Fingertips: Liquid-Liquid Extraction Basics
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
Simultaneous Pump and System Sizing
Flow analysis can aid in simultaneously sizing pumps and associated piping systems. The concurrent sizing can reduce wasted energy and improve pump reliability In the chemical process industries (CPI), a variety of incredible process-simulation tools are available to provide greater…
