As economical separation of contaminants from natural gas becomes increasingly important, simulation eases the design of innovative module to remove carbon dioxide. Membranes offer potential advantages over other methods.

Automating procedures within control systems can serve to make your operators more effective and more consistent. With studies showing more than 40% of all plant incidents stemming from some form of human error, it makes sense to give automation a larger role in day-to-day operations.
By integrating smart motor control centers that will monitor energy consumption a plant can remove wasteful energy expenditure, prevent unplanned downtime, and improve overall operational efficiency. Recent tax code amendments make these improvements inviting.
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.
Understanding how changing a work environment affects people can reduce accidents. Management of Change (MOC) has been one of the hardest of the PSM requirements for industry to master. Making matters worse, its rarely applied to people and organization changes. But there are proven approaches.
More attention to steam systems and trap monitoring provides big benefits. At most chemical plants, plant management and operators face increasing pressures to improve the energy efficiency of their processes, so they should see how they can save on steam.
Senior Editor Dirk Willard discusses Shigeo Shingo's take on mistake-proofing, or Poke Yoke, if you speak Japanese. The practice suggests the following devices: eliminate redesign, facilitate guide, mitigate lessen the damage caused by the error, or flag identify the error.
Faster. Smaller. Smarter. Modular. All express the future of process analytics. And un-stoppable describes the ongoing migration of process analytical instruments to continuous, online, field-mounted use at chemical plants.
For you to succeed in advancing your strategy, while keeping the peace, you must meet many challenges motivating personnel and juggling the integration of changes. The solution is better plant-wide communication and understanding of the alarm philosophy.
