The skirts on the new CE Series pipe caps are designed to stretch over the pipe edges while retaining their shape and tight fit. This feature allows them to be installed without tools. Ribbed skirts provide ventilation to ensure that…
The Puron Plus membrane bioreactor (MBR) system is a skid-mounted packaged plant that provides customers with a full scope of supply from prescreening and biological treatment through to the final membrane clarification step. The Puron Plus is designed for both…
Fully serviceable inline, Clampseal blowdown valves provide control for continuous boiler or turbine blowdown, as well as bottom blow-off service. The valves feature a uniform, single-piece gland, a cartridge-type packing chamber and pressure seal backseat. For continuous blowdown service, Clampseal…
Installed gain graphs can help improve the selection of control valves for chemical processing. The graphs are plotted to analyze together control-valve flow characteristics and process-system flow characteristics, and better illustrate the relationship between a control valve and the system.…
Last month at the Chem Show, Chemical Engineering (CE) had the pleasure of honoring this year’s finalists and the winner of the 2009 Kirkpatrick Chemical Engineering Achievement Award, a biennial prize that the magazine has bestowed continuously since the early…
The desire to move from batch to continuous processes for the production of high-value organic molecules has become more widespread in recent years as evidenced by the increasing number of related studies published in the literature. The benefits of continuous…
The ultimate objective of storing liquid, fluid and gaseous products, which may be corrosive, flammable or unstable, is to store material in an environmentally safe and economically viable manner. Storage tanks in the chemical process industries (CPI) can be most…
Corrosion is estimated to account for a significant portion — 8–10% — of total annual-plant-capital expenditures for the chemical process industries. To avoid it, engineers can consider corrosion-resistant plastics for process piping and storage vessels. Thermoplastics are generally resistant to…
There are many considerations when choosing piping materials for an industrial system. Historically, when options were more limited, the decision-making process was relatively straightforward. It was a matter of choosing what grade of metal to install. Today, there is a…
New radial diaphragm valves improve 'cleanability' A single-body valve design with boreline seal that minimizes entrapment areas is responsible for the ease of cleaning. The DR Series of valves (photo) is designed for sterile flow streams in media preparation, fermentation,…
