There is something about opening a box labeled “some assembly required” that causes one of two reactions—the joy of the challenge or dread. In actuator commissioning, the dread comes from not being an actuator expert, in which case installing and commissioning that actuator may appear at first glance to be difficult.

On Nov. 15, 1990, the Occupational Safety and Health Administration (OSHA) made into law the standard for process safety management (PSM) of highly hazardous chemicals (29 CFR 1910.119), as well as section 304 of the Clean Air Act (CAA) amendments. The PSM standard and CAA changes were enacted in direct response to the Union Carbide India Ltd., Bhopal, India disaster that occurred on Dec. 2, 1984 and resulted in the deaths of 3,787 individuals. For the many valve and actuator users that operate processes involving hazardous materials, the changes mean analysis of PSM and creation of programs that should ensure a similar tragedy does not occur. Because pressure relief can be a last line of defense, PSM must address pressure relief systems.

Attendees at this year’s workshop Aug. 8-9 in San Diego received mostly positive reports from speakers who agreed that, while the nation is in recovery, the road forward is filled with more than a few bumps. While abundance and availability of natural gas is definitely a major influence, speakers said North America’s economic future will also be affected by the upswing in tight oil production. Those two factors could lead to energy self-sufficiency on the continent by the end of this decade and fuel a resurgence in the domestic petrochemical and manufacturing industries thanks to low feedstock prices and relatively inexpensive electricity.

In many regions of the U.S., the proliferation of gas and liquids discovered and extracted from shale formations has created a need for rapid infrastructure development. Valves and their automation play key roles at every stage of processing and transporting the gas and fluids—from the well to the storage facilities and distribution systems. This means they are vital in providing safety to personnel, process control for operations and protection for valuable assets as well as prevention or mitigation in the case of environmental events.

Regulators’ monitoring of emissions has forced industries to either implement proactive programs of leak detection and repair (LDAR) or deal with implications of non-compliance, which include fines and consent decrees. In either case, advanced sealing technology can help: It allows an entity to avoid noncompliance or adhere to the low-emission consent decrees.

Liquefied Natural Gas (LNG) is exactly what it says: the liquid form of natural gas. The process of liquefying is performed to reduce the volume for purposes of transporting the fuel: LNG reduces volume by 600 times, making it much more economical to transport by sea aboard LNG carrier ships to destinations all over the world.

Winners and losers in the world of valves, like in most industries today, are created as the players react to a constantly changing environment and marketplace.

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?
