Cooling Towers: Estimate Evaporation Loss and Makeup Water Requirements

Applying mass and energy balance calculations yields critical operating insight Cooling towers are an important unit operation in chemical process industries (CPI) operations. Applying mass and energy balance calculations enables process engineers to evaluate evaporation loss, blowdown and makeup-water requirements,…

New chemical solution for dust suppression

Sentinel dust suppressant (photo) is a proprietary chemical that is designed to adhere the finest silica particles to larger particles to prevent the fines from becoming airborne. The chemical is sprayed onto sand grains and adheres to the small dust…

A powerful radar level sensor for powders and bulk solids

The NCR-80 non-contact radar level sensor (photo) for powders and bulk solids features an 80-GHz frequency focused in a narrow 4-deg beam angle, enabling precise aiming to avoid the flow stream, internal structure or sidewall buildup. This ensures reliable performance…

This vibrating-fork level detector has wired HART connectivity

Rosemount 2140 (photo) is said to be the world’s first wired HART vibrating-fork level detector. The Rosemount 2140 detects level in applications with high temperatures and harsh conditions that are unsuitable for other level-monitoring devices. It is easy to install…

Monitor reformer-tube temperatures in realtime

The near-infrared borescope NIR-B 3XR (photo) delivers continuous, high-accuracy reformer-tube-wall temperature (TWT) measurement, furnace optimization and monitoring, giving operators the ability to measure temperature point data and to store this data for future analysis. Operating with a wide-angle field of…

Contact-free pump operation minimizes contamination

The Dry-Pro line of dry vacuum pumps (photo) feature contact-free operation that requires no lubrication in the pumping chamber, minimizing process contamination and pollution caused by the pump operation. The Dry-Pro line offers dry-screw vacuum-pump designs with fixed- or variable-pitch…

Software add-on enables apps that integrate with CAD

This company has updated its LiveLink for SolidWorks products. As an add-on to the company’s Multiphysics software, LiveLink for SolidWorks allows a computer-aided design (CAD) model to be synchronized between the two software packages. The latest version of LiveLink for…

Explosion protection for plastic extrusion applications

The EBP Series of explosion burst plugs (photo) are used to protect plastic extrusion equipment from overpressurization. The EBP Series’ welded design provides a flush attachment, preventing potential product buildup. Stronger welded joints make EBP devices more resistant to increased…

A portable gas monitor with an extremely long service life

The BW Clip4 (photo) is a new four-gas, portable monitor that can operate continuously for two years without the need to change sensors or charge batteries. BW Clip4 monitors significantly reduce maintenance costs associated with fleets of portable gas detectors…
