Sanitize, Analyze and Optimize Bioprocessing Operations

Better designs and improved monitoring and control technologies lead to higher efficiencies While bioprocessing can be challenging due to the sanitation requirements and exacting processes, new technologies are allowing bioprocessors to more easily sanitize, analyze and optimize their processes in…

Facts At Your Fingertips: Design Considerations for Pneumatic Conveying

Attention to the design of bulk-solids pneumatic-conveying pipelines can help avoid conveying-system problems, such as low conveying rates, plugging, excessive wear-and-tear in the conveying line, high conveying-system pressure drop, product breakage, fines generation and product cross-contamination. This one-page reference provides…

Technology Profile: Production of Linear Alpha Olefins

Linear alpha olefins (LAOs) are hydrocarbons with the chemical formula CnH2n, characterized by linear chains and one double bond at the alpha position (Figure 1). Such hydrocarbons are important chemical intermediates, widely used in several industrial and consumer products according…

A System Approach with Flow Analysis

Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…
