Feed injector lowers energy consumption of FCC units

A newly launched feed injector for fluid catalytic cracking (FCC) units at petroleum refineries reduces the oil-side pressure drop and lowers the steam required, enabling facilities to achieve the same performance with lower energy consumption, according to developer Lummus Technology…

Blast-furnace technology aims for carbon neutrality

Primetals Technologies, Ltd. (London, U.K.; www.primetals.com) and thyssenkrupp AG (Essen, Germany; www.thyssenkrupp.com) have signed an exclusive, worldwide cooperation agreement that sees both parties commit to bringing the Sequence Impulse Process (SIP) technology to the market. The SIP technology has been…

Paving the way for emissions-free renewable fuels

UOP, LLC, a Honeywell company (Des Plaines, Ill.; www.uop.com) and Wood plc (Aberdeen, Scotland; www.woodplc.com) are now licensing a combined technology suite that brings together UOP’s Ecofining renewable-fuels process with Wood’s Terrace Wall hydrogen-reforming furnace, with the aim of substantially…

Technology Profile: Production of Vinyl Acetate

Vinyl acetate (also known as vinyl acetate monomer; VAM) is important in the manufacture of many polymers and resins. The greatest demand for vinyl acetate is associated with the production of polymers and copolymers, mainly poly(vinyl acetates) used in papermaking,…

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…

Field Calibration of DP Flowmeters: Best Practices

Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…

A flexible, origami-based fuel cell

Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…
