Processing plants today do everything they can to increase efficiency and productivity. Frequently, that involves operating at higher temperatures, pressures and flow rates, which means higher pressure differentials across critical control valves as well other conditions that generate more noise. While this noise has always been a problem, it is even more so in today’s high-throughput processing plants.

Dry chlorine gas is found within chlorine production, storage and transfer facilities, as well as in downstream processes such as production of vinyl chloride monomer (used in making polymer polyvinyl chloride) or phosgene (used in applications such as pharmaceuticals and organic compounds). Dry chlorine is generally understood to have less than 150 parts per million (PPM) water containment.1 Moisture contamination in any of these dry chlorine service areas, however, can result in the formation of dendrites, crystal-like masses that can cause problems.

This article is a follow-up to the VMA & VRC 2012 Annual Meeting presentation by Harry Moser, founder and president of the Reshoring Initiative. The non-profit Reshoring Initiative is dedicated to helping companies understand the true cost of offshoring by using Total Cost of Ownership (TCO) analysis. The initiative provides free TCO estimator software, as well as a database of more than 300 reshoring articles and case studies where companies can share their experiences with reshoring.

The economics and simplicity of wireless field instruments has allowed many industrial plants to expand the benefits of automation well beyond traditional “wired” control.
Wireless technology has created monitoring applications for safety, reliability, maintenance, environmental compliance and increased personnel efficiency that are possible without incurring the traditional cost and time barriers imposed by wires. Globally, plants are replacing manual clipboard rounds, automating periodic inspections and monitoring more assets than ever before because of these new applications. But what is the status of wireless control of valves in particular?
