Technology Profile: Ethylene oxide production from ethylene

This column is based on “Ethylene Oxide Production from Ethylene – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/ethylene-oxide-production-cost. Ethylene oxide (also known as EO, oxirane and epoxyethane) is the simplest cyclic ether. Because it…

High-volume twin-screw feeder delivers precision

The Model TSF twin-screw feeder (photo) is designed for precise batching and weighing applications, including: batching to weigh hoppers; low loss-in-weight, scale-monitored flow; low loss-of-weight batch applications with scales; drum and pail packout lines; and recipe-type batching by multiple computer-controlled…

This power supply has a new IO-Link Communication Module

The Pro 2 line of power-supply units (PSU; photo), with units ranging from 120 to 960 W, can connect to various gateways via a snap-on communication module (currently, IO-Link; Ethernet-based protocols such as Modbus TCP, Ethernet IP, ProfiNet in the…

How a Waste Treatment Plan Can Improve Your Bottom Line

Although waste is unavoidable in industrial processes, many companies are turning toward business strategies that seek to treat waste with minimal environmental impact — or even better, prevent waste altogether In the past, waste was simply discharged without any treatment.…
