This new automatic valve performs multiple functions in a piping system, including pressure relief, backpressure control, pump bypass and anti-siphon protection. The lug-mounted Series RVDT uses an adjustable, non-wetted spring to control backpressure in a piping system. The set point…
Last year, the U.S. Environmental Protection Agency (EPA;Washington, D.C.; www.epa.gov) proposed new emissions standards for hazardous air pollutants (HAP) emitted by industrial boilers and solid-waste incinerators (CISWI) based on the performance of the maximum achievable control technology (MACT). The so-called…
GE Power & Water (Trevose, Penn.; ge.com) has introduced an improved membrane bioreactor (mbr) technology whose productivity is said to be 15% higher than that of its predecessor for wastewater treatment plants. The new system, called LEAPmbr, was derived from…
Almost by definition, chemical engineering is a “green” discipline today, as it so often involves efforts to optimize chemical processes in order to reduce the amount of energy and raw materials that are used and the amount of waste that…
The lowest KR values in rupture discs KR values are used to determine the frictional flow loss in rupture discs. While the perception is that all rupture discs have high KR values, this company’s FAS (Forward Acting Scored) and PRO+…
LB/FB Remote I/O Systems are used to connect intrinsically safe Namur switching signals and solenoid valve outputs as well as temperature inputs, or the supply of two- or four-wire transmitters, proportional valves and positioners. LB Remote I/O is installed in…
The realization that our natural resources are not endless, and that we need to focus on sustainability is driving technology and its supporting funds toward new choices. In the chemical process industries (CPI), engineers are looking for alternatives to the…
The Mobile Perimeter System (MPS) IV (photo) is a mobile gas-monitoring platform that can be rapidly deployed for temporary or remote gas-detection applications. The solar-powered unit has an onboard strobe and siren, and can be configured with wireless communication. The…
For years, clay has been the go-to product for spill containment simply because it was cheap and did the job. While clay, also referred to as diatomaceous earth, sand or kitty litter, will always have a place in in spill…
Developed for installation in confined spaces, the ready-to-connect pressure booster systems Hya-Solo D FL Compact (photo) and Hya-Duo D FL Compact systems comprise several close-coupled pumps, an inlet tank mounted on the same baseplate and components for controlling and monitoring…
