Chemical Processing - January 2008 - (Page 44) >> EQUIPMENT & SERVICES REACTOR INTEGRATES PLATE EXCHANGER This plate reactor is said to allow faster scale-up, improved yield and better control of the reaction compared to classic stirred-tank reactors. The unit combines the properties of a continuous chemical reactor with those of a plate heat exchanger. It contains flow-directing reactor plates that are sandwiched between heat transfer plates, held together by pressure plates to create a modular reactor unit. Ports along the reaction channel provide access to the reaction mixture for measurement, sampling and reactant addition. The plate reactor can be disassembled and reassembled quickly, enabling easy cleaning. The mechanical design of the reactor allows for reaction at elevated temperature and pressure. The product range has capacities from 0.25 l/h up to 1 m3/h covering all steps from laboratory scale R&D to full production.

The electrode design includes an open junction, which solves the problem of diaphragm fouling often found in applications where sticky media, solutions with high particle content, or sulfide-bearing solutions are present. It integrates a polymer composition with the open junction reference system to ensure the performance and sensor life required for challenging applications. Mettler-Toledo Ingold (781) 301-8808 www.mt.com/pro NON-CONTACT LEVEL TRANSMITTER IS LOOP-POWERED The LVU800 Series general-purpose two-wire ultrasonic transmitter with NEMA 4X enclosure provides non-contact level measurement up to 10 m (32 ft.), and is said to be ideally suited for challenging ultra-pure, corrosive or waste liquids, as well as atmospheric bulk storage, day tank and waste sump applications. It features simple, fast set-up with pushbutton calibration. Media examples include wastewater and sodium hydroxide. It also is CE Compliant. Models include the LVU816, LVU826 and LVU832. Omega Engineering (203) 359-1660 www.omega.com CENTRIFUGAL SCREENER CANTILEVERS FOR QUICK CLEANING The medium-capacity Centri-Sifter centrifugal screener model “MO” features a cantilevered shaft with two, externally-mounted bearings between the screening chamber and motor drive, allowing all internals to slide freely from the shaft end for cleaning, screen changes, or inspection. Wide spacing between the bearings, a large diameter shaft, and a flexible shaft coupling combine to prevent vibration, even at high speeds under heavy, imbalanced loads, according to the company. Configurations are offered for continuous operation in-line with dilute-phase pneumatic conveying systems, as well as gravity-fed applications. Opening a hinged door at the discharge end of the screening chamber allows a retainer plate, screen cylinder, and helical paddle/feed screw assembly to be removed in one minute, says the company.
