New technologies to treat water in refineries and petrochemical plants: Giving the right water treatment solution to refineries and petrochemical plants is a big challenge. Nalco has addressed this problem with a holistic cooling water management system.

Evonik is currently working on the development of a new process for producing methyl methacrylate (MMA), an important precursor for Plexiglas and for specialty applications such as contact lenses and adhesives.

Partnering with an adept fluid management company – which has a vast experience from almost all types of process plants and 100 countries of the world – makes sense to encounter the ever-increasing challenge to move aggressive, corrosive, explosive, solid-laden or viscous fluids, under high pressure and extreme temperature condition.

Since many ports were not able to cater with the spurt in demand for coal and iron ore world wide, offshore transshipment became the only answer. Up-to-date transshipment facilities employ more than one crane on the pontoon and a complex cargo handling system consisting of hoppers, conveyors and ship loader. Three examples show how it is done.

Tunable diode laser (TDL) technology has proven to be exceptionally reliable for measuring trace gas components like H2O, H2S, CO2, NH3 and C2H2. TDL absorption spectroscopy (TDLAS) is a highresolution technique that enables the measurement of specific gases with precision while avoiding interferences that are common with traditional analyzers.

Engineering specialists Foster Wheller supply a retrofit-selective catalytic reduction (SCR) system for a coal fired power plant in Naantali, Finland. SCRs are used in the exhaust cleaning for therml power genertion.

When mixing sticky bulk solids, residues can be quite a challenge. They pose the threat of cross contamination or product impurities. Since rinsing mixer and screw with water and liquid cleaning agents bring unwanted moisture into the machine, dry cleaning methods can be an attrcative alternative. But also this approach poses several challenges – in a short interview with PROCESS Worldwide, Hendrik Freije, application engineer of Hosokawa Micron’s Food & Pharma team, talks about the Do’s and Dont’s of dry cleaning.

Residues of bulk solids in mixers can be quite a nuisance if one device is used for several products. While rinsing mixer and screw with water is an easy approach to cleaning, it has certain disadvantages, most obvious the presence of moisture within the device. But also dry cleaning poses its challenges – several aspects have to be considered when laying out a dry cleaning procedure for powder mixers.

Over the course of their long existence solenoid valves have developed slowly but continuously so that they are opening up new fields of application. Today they are a central element in controlling fluids in a broad spectrum of different applications. One of the newer areas of application is in the life sciences. A new actuation technology now allows a significant reduction in size with no loss of performance.

Separlab, a Czech specialist in high-performance liquid chromatography (HPLC), has standardized on Wanner seal-less Hydra-Cell multi-diaphragm pumps in its industrial-scale systems, using them to deliver solvents for the mobile phase and to inject sample mixtures. Learn why the company prefers such “specialists” over single-diaphragm and piston-plunger pumps in these applications.
