With the new high risk chemical facilities federal anti-terrorism regulations, its time for the chemical industry to ratchet up its cyber-security efforts. Theres a surge in interest in cyber-subjects such as security certification, defense-in-depth strategies, risk-based planning and improved policies and procedures.
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.
Recognized throughout the world for decades as an innovator in the field of mass transfer products, Sulzer Chemtech opened its first Houston facility in 1998. That was the first step in a series of moves designed to position the company in the U.S. market.
In spite of their large operating cost, most pump systems are inefficient by design. Among the common design problems are non-optimal pipe sizing, control valve utilization and, perhaps most common, incorrectly sized pumps. How a pump operates depends on the system, so improvements must focus on the system as a whole.
