In the chemical industry, the availability and reliability of your equipment is key if you want to keep producing the purest end product in a way that is also cost-effective. In many agrochemical and base chemical applications as well as…
In terms of product purity, plant safety, and reliability, chemical manufacturers are operating in one of the most challenging industries. In order to keep production running as well as meeting the highest safety and hygiene standards, selection of the technologies…
Technical salts and crystallization products have found a broad spectrum of different applications in the industrial sector in the past decades. One of the most frequently used salts is sodium chloride, which is an important component in the human diet,…
Ragn-Sells AB (Sollentuna, Sweden; www.ragnsells.com) has partnered Hitachi Zosen Inova AG (Zürich, Switzerland; www.hz-inova.com) for the construction of a new plant that is designed to extract resources from flyash — a toxic byproduct of waste incinerators that normally ends up…
Traditionally, cyanide consumption with conventional bio-oxidation residues is higher than with residues produced through other oxidative technologies. The Outotec MesoTherm BIOX process, based on its proven mesophile BIOX process, offers an easy, cost-effective upgrade path that can cut cyanide consumption…
Fats, oil and grease (FOG) waste can create environmental problems for water-treatment and sewage systems, but can be a potential resource if collected and separated efficiently. A technology originally developed by Downey Ridge Environmental Co. (Lansing, W.Va.; www.greasezilla.com) to separate…
In a project called ReeMAP, LKAB Minerals AB (Luleå, Sweden; www.lkabminerals.com) is developing technology to recycle mine waste to produce phosphorus mineral fertilizers, rare earth elements (REEs), fluorine and gypsum. The first step is to use the mine waste to…
