These blowdown valves can be fully serviced inline
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…
Avoid kinking on tight turns with this tubing
Parker Hannifin Tex-Flex fluorinated ethylene propylene (FEP) corrugated tubing (photo) can turn sharp corners without kinking. The manufacturer asserts that the tubing can handle bend diameters four times smaller than a typical smoothbore tube of the same size. The tubing’s…
This mixer is available in a wide size range
Charles Ross and Son The VersaMix Model VMC (photo)is offered in sizes ranging from 1– to 750–gal working capacity. The model has an air/oil lift system that raises and lowers the agitators from the mixing vessel. The vessel is attached…
Transfer flammable liquids safely with this pump
The SCP-6500 (available March 1, 2010) is designed to accommodate the transfer of alcohols, volatile hydrocarbons and flammable solvents. The pump features a lug with a grounding wire to allow users of flammable liquids to ground it, making the pump…
40th Kirkpatrick Award Announced
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…
Millichannel Reactors: A Practical Middle Ground for Production
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…
Creating Installed Gain Graphs for Control Valves
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.…
Aboveground and Underground Storage Tanks
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…
Chemical Resistance of Thermoplastics
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…
CPVC Piping In Chemical Environments: Evaluating the Safety Record
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…
