Distillation and absorption are back. The AIChE Spring Meeting (San Antonio, April 28–May 2) proved it and the fall meeting to be held in November will muffle any doubting Thomases. During the late 1970s and early 1980s, I spent appreciable…
The Farr Gold Series dust collection system is now available in a simplified skid package. The high-efficiency cartridge dust collectors and all associated equipment are incorporated onto a single platform, for ease of transport and installation. In addition to dust…
Many chemical engineers study or employ distillation trays, gas-liquid separators and spray nozzles. Most of those engineers have studied or employed force balances around liquid droplets suspended in upward-flowing vapor streams. Considering a droplet of size “ d, ” for…
For separation columns, this multidisciplinary engineering company offers a high-performance random packing called Cascade Mini Ring, which is also available with a special surface treatment; and a high-performing structured packing MC Pack (photo), which has a specialized configuration. Liquid distributors…
At AchemAsia, this engineering company presented its range of filters and filtration plants for the chemical, food, biotechnology and environmental industries. For example, the Hi-Bar range of continuous pressure filters is said to offer new solutions for filtration, washing and…
The operating costs of direct, steam-heated evaporators can significantly be reduced by revamping with mechanical vapor recompressors (MVRs), according to this company. For example, a four-effect, directly steam-heated evaporation plant, designed for 30 ton/h of water evaporation initially had a…
Sulfur is a major contaminant in the oil and gas industry that exists in various forms and requires separation from both water and process streams. In recent years the removal of sulfur species has received increasing attention because of safety…
The HemiPleat eXtreme nano-fiber filter offers higher filtration efficiencies, greater durability and better resistance to pulse cleaning than competitive products, the company says. The standard HemiPleat filter delivers MERV (minimum efficiency reporting value) 15 efficiency — higher than the MERV…
Three new types of Lewabrane membrane separation elements for reverse osmosis (RO) are now available. These new products are suitable for water with strong fouling potential. The new elements were designed to generate greater turbulence in the feedwater channel, meaning…
The newly launched Sartoguard NF prefilter series feature a unique combination of high-performance polyethersulfone (PES) membranes and nanofleece technology. This is said to be the first time that PES nanofleece material is being used for liquid prefiltration applications in biopharmaceutical…
