  • Achieve continuous safety improvement

    Enhancing safety performance requires diligence and unrelenting effort. The Independent Safety Review Panel’s recently released report on the safety culture and practices at BP’s U.S. refineries where a March 2005 explosion occurred in Texas City, Texas indicates similar failings are likely elsewhere in the industry. Learn what can be done to enhance continuous safety improvement.

  • Combat contamination

    Consider the impact of slope, fittings and valves. Plants can lose sizable amounts of money each year because of contamination caused in process lines. Owners and contractors alike can take steps in the design and construction phase to enhance the drainability and cleanability of a system.

  • Get full value from partial stroking

    There are two main drivers for partial stroking of valves in safety systems: the desire to extend manual test intervals to as long as possible; and to reduce the amount of redundant hardware required for higher safety integrity levels. Like most things in life, it all boils down to one thing: trying to save money.

  • Sample pump eliminates emissions

    A compact system significantly improves analyzer accuracy. This innovative turnkey solution for analyzer emissions is a solid-state pump with an ultra-sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure — even during times of plant upset.
