Wireless Gas Detection
Widespread adoption of the WirelessHART network protocol (IEC 62591) and recent advances in lithium battery technology have made it affordable to supplement wired detection systems with wireless systems, improving plant safety and regulatory compliance. This paper addresses recommended practices in implementing fixed-point gas detection across WirelessHART networks. We will approach the topic through the lens of life safety at two levels — the device and the network. Although many of the considerations will apply regardless of which wireless protocol is adopted, we have chosen to focus on WirelessHART because of its growing prevalence in the market.
Industrial processes such as oil and gas production facilities, refining, chemical production and power generation often involve toxic and combustible gases, which can create serious hazards if they escape into the air. To minimize risk to personnel and plant safety, plants often deploy early warning devices such as gas detection systems, which require expensive infrastructure and seldom cover all of the potential leak points This extra cost is driving a trend towards augmenting existing wired gas detection coverage with wireless sensors, which can significantly increase monitoring coverage with minimal new financial outlay.
The reliability of today's safety control technology is only as good as the instrumentation networks that feed it. These are becoming increasingly complex, putting safe and cost-effective plant operations in jeopardy. While there remains considerable variation in the quality of the sub-system infrastructure, there is increasing awareness of the risk, cost of ownership and sustainability of all elements of process safeguards, including, and especially, the Safety Instrumented System (SIS).
This paper discusses ways that plant safety teams can reduce complexity, maximize safety, and minimize operation and maintenance costs.
United Electric Controls, a market leading provider of safety switches, recently briefed ARC Advisory Group on its new One Series Safety Transmitter. The company believes that its safety transmitter represents groundbreaking technology offering unprecedented performance at an affordable price. Key findings include:
In today’s world of standardized communications, no man is an island and neither is any process control system. Networking is about to expand greatly, thanks to the increasing adoption of integrated devices, the internet, and a proliferation of open operating systems. Increasing attacks that exploit weaknesses in the network may not be far behind. Real world examples have shown that control systems can be hacked, sometimes with deadly results.
World energy demand will grow at 1.2 percent a year for the next quarter century, according to a 2010 report from the International Energy Agency. Fully half of that growth will come from fossil fuels – coal, gas and oil. Thus, increasing oil and gas production understandably attracts considerable attention, with traditional and unconventional sources both being asked
to satisfy the world’s growing hunger for energy. However, that production must meet safety and regulatory requirements. Together, these ensure that the extraction of fossil fuels from any source protects equipment, people and the environment. It is important not to skimp in satisfying such requirements, as the cost of a safety-related failure can literally run into the billions. Fortunately, there are technological solutions that help meet this challenge in the form of advanced switches and transmitters. These can help maintain safe casing pressure, improve safety panels, and ensure that blow out preventers do their job. Beyond safety, applying the right technology can improve asset management and increase uptime. This white paper will examine the changing oil and gas production safety environment, explore solutions, and outline the advantages in addition to safety that can result.
Safety implementation typically is done by a group that includes plant instrument engineers and technicians, who are charged with finding simple and reliable solutions. Often, these situations involve the question of when to shut a process down. Such decisions frequently hinge on key process variables such as flow, level, temperature and pressure. These must be in a specified range at various locations within chemical and petrochemical plants, refineries and power plants, including everything from critical process vessels to eye wash stations.
