White Paper: Improving Health and Safety with Magnetic Level Indicators in Ammonia Refrigeration Applications

Anhydrous ammonia is a versatile commodity in many manufacturing applications, including cold storage and food processing facilities. In comparison, anhydrous ammonia raises a range of safety and environmental issues to be addressed when determining some form of process instrumentation. Traditionally, visual level indication of anhydrous ammonia was obtained using sight glasses. This white paper discusses key areas in the ammonia refrigeration process where magnetic level indicators (MLIs) can provide a safer , more reliable method of level measurement over conventional technologies.

The goal of this document is to highlight the benefits of MLIs that will lead to improved personnel safety , reduced risk of fugitive emissions, reduced environmental impact, and reduced maintenance costs in large commercial and industrial ammonia refrigeration systems.

Understanding Safety Integrity Level (SIL)

Nothing is more important than safety to the process control industries. High temperature and pressure, flammable and toxic materials are just some of the issues faced on a daily basis. Reliability is a key component of safety; the more reliable the device, the safer the critical process.

Safety integrity level (SIL) is defined as "relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction." SIL ratings are applied in accordance of frequency and the severity of the hazard. These ratings determine the level of performance required to achieve and maintain safety, as well as the probability of failure.

There are four SIL levels; SIL 1, SIL 2, SIL 3, and SIL 4. These SIL levels relate to the risk of failure - a higher the SIL rating poses a higher risk of failure, in turn requiring stricter safety requirements.

Magnetrol, a leading manufacturer of innovative level, flow and volume controls for the process industries has put together this excellent technical note to help you better understand Safety Integrity Level.

Wastewater Treatment Facilities May Play Important Role in Tracking Coronavirus

New studies show that SARS-CoV-2, the virus causing COVID-19, is shed in human feces and is collecting in our city sewers.  If the pandemic continues in waves as the latest estimates believe, wastewater treatment plants could provide early warnings to prevent ICUs and hospitals from being swarmed.

Environmental microbiologists have studied pathogens in sewage for decades. In 1989, Israel set up a Polio virus sewage surveillance system. The use of sewage pathogen monitoring in wastewater treatment facilities as a public health surveillance tool, however, is a fairly new area of study.

Biobot, Somerville, MA company who specializes in wastewater epidemiology, is establishing protocols to test sewage for SARS-CoV-2. If successful, this data will give communities a dynamic map of the virus as it spreads to new places.

Data from sewage will enable communities to:

• Measure the scope of the outbreak independent from patient testing or hospital reporting, and include data on asymptomatic individuals,
• Provide decision support for officials determining the timing and severity of public health interventions to mitigate the overall spread of the disease,
• Better anticipate likely impact on hospital capacity in order to inform hospital readiness and the necessity of public health interventions,
• Track the effectiveness of interventions and measure the wind-down period of the outbreak, and
• Provide an early warning for reemergence of the coronavirus (if it does indeed have a seasonal cycle).

It needs to be mentioned that experts believe, based on previous coronavirus research, that SARS-COVID-2 is effectively removed through traditional water treatment processes. The focus on these public health surveillance efforts track virus levels prior to treatment.
