  • Build your portfolio

    Is energy efficiency an engineering project or a management process? Contributing Editor Christopher Russell answers that question in this month's Energy Saver column.

  • Gamma scanning seeks an inside edge

    Many companies decide not to build up certain capabilities in-house mainly because they don’t have sufficient regular demand for them. Gamma scanning of distillation columns is a case in point, but on-site scanning specialists may be the wave of the future.

  • Properly deliver compressed gases

    From large petrochemical units to tiny pharmaceutical pilot plants, day-to-day operations depend upon providing compressed gases in a controlled, safe and environmentally conscious manner. Correct gas handling also can improve process efficiency.

  • Cut column energy consumption

    With increasing energy prices and public sensitivity to energy consumption, many plants are paying more attention to optimizing distillation. Simple and low-risk operational changes often can provide substantial savings.

  • Flame Modeling Provides Matchless Results

    A computer simulation helps solve a refinery combustion problem. Finding ways to limit NOx from fired heaters, especially under stringent environmental regulations, has become a major concern for the petroleum refining industry. Complying with new stricter regulations, a Texas refinery upgraded the burners in one of its large cylindrical furnaces.

  • Chemical industry starts to shine through clouds

    In its third year, Chemical Processing’s online salary and job satisfaction survey results provides reasons for optimism. The record 1,830 survey respondents’ answers indicate salaries, raises, bonuses and job satisfaction are all moving in a positive direction.

  • Exporters get reporting relief

    EPA eases annual reporting requirements and thresholds, and exporters are feeling relief, according to Lynn Bergeson in her monthly Compliance Advisor column.

  • pH sensor stands up to tough conditions

    Design provides improved reliability in a polymer-precursor batch reactor. Sensors must respond quickly and survive a harsh environment. Poor probe reliability can make the difference between a process that makes money and one that doesn’t.

  • Distillation control and optimization, Part 3

    Control's Béla Lipták continues his series on control of distillation processes, this time focusing on managing reboiler flow, temperature, feed rate, loading and reflux for economy, stability and safety.

  • Wal-Mart applies clout

    Wal-Mart Stores, Inc., previously committed to reduce by 5% the packaging used by its 60,000 suppliers by 2013. Now, a new initiative uses a scorecard to tackle wasteful packaging.

  • Make jacketing your strong suit

    Small details in jacketed-pipe configuration can have a big impact, according to Chemical Processing's Contributing Editor Andrew Sloley.

  • Valve innovation helps with nuclear waste

    Valves and actuators designed for handling radioactive waste must meet strict government requirements. This sometimes requires unconventional solutions. Such was the case at the Hanford Waste Treatment Project (WTP), Hanford, Wash.

  • Tiny reactors aim for big role

    Process Intensification (PI) has promised many things but has it fulfilled its promises? When looking at reactor technology, the answer is a definite “Yes.”

  • Consider changing the speed not the pump

    Chemical Processing's Contributing Editor Andrew Sloley advises that instead of reflexively resorting to brute force to provide enough head, adjusting the pump speed might make for a better solution.

  • Avoid trouble with slurries

    Handling slurries (a mix of solids and liquids), should be based on experience and experiments, not theory. Much of the knowledge obtained from pneumatic conveyors and fluidization systems can be used in understanding slurries.

  • Choosing motor controls and drives

    In any industrial control application, using the right drives and motor controls can make or break the project, and also can make a huge difference in how well those applications perform.

  • Implementing an operations management system

    Things are changing at warp speed. Manufacturing companies are collecting large volumes of data from data systems but improvements are possible only if the data are analyzed and developed into useful business parameters.
