Rupture discs are designed to fail. That's their job. 

These sacrificial parts are designed to burst when pressure within production equipment exceeds a certain threshold by breaking down, stopping the process to prevent or mitigate hazardous events. Rupture discs are critical instruments utilized so that companies can ensure process safety as set forth by the International Safety Standards (IEC 61508/61511). These devices prove most effective when they fail according to pre-established specifications. Inferior rupture discs often cause unnecessary and expensive production shutdowns due to the lack of quality testing and expertise in manufacturing.

A rupture disc (pressure safety disc, burst disc, bursting disc) is a “one and done” pressure relief device most often used to protect a vessel, pipe, or container from over pressurization. As opposed to pressure relief valves, rupture discs are designed to function only one time by providing an instantaneous response to an over-pressure condition.

Rupture discs are commonly used in chemical, petrochemical, nuclear, aerospace, medical, railroad, pharmaceutical, food processing and gas & oil applications. They provide primary or backup protection. Very often rupture discs are used in tandem with safety relief valves, protecting them from the process media and extending the life of the relief valve.

Three Tips to Optimize Cooling Water Management for Lower Plant Operating Costs

Evaporative cooling towers
Evaporative cooling towers

Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries. They also are essential in the heating, ventilation and air conditioning (HVAC) systems that provide climate control in large facility complexes, such as educational and corporate campuses; casinos, hotels and convention facilities; data centers, and government, research and medical buildings.

The proper control and treatment of cooling water is essential for efficient, safe and economical operations. Chemicals are fed to these systems that protect against fouling, corrosion and microbiological contamination. The proper dosage of these key chemicals is determined by having accurate information on the system make-up and blowdown water.

To achieve effective cooling through the cooling tower, it is necessary to maintain proper design flow through the cooling tower and thus provide adequate cooling of the system. Insufficient cooling water can affect critical equipment or building climate control. Accurate flow meters are the most effective tool to achieve reliable flow results and control system costs.

Here are three ways to optimize cooling water management with flow meters:

Tip 1: Install a flow meter at the plant water intake source, which can turn the meters sub-meters. Comparing the flow data on all three lines helps identify potential water leaks and determine the system water balance plus other system issues.

Tip 2: Install flow meters upstream from pumps to provide flow data alerting the system to low flow situations leading to potential pump problems caused by low flow conditions. Otherwise, the result can be expensive pump repairs or even system shutdowns.

Tip 3: Accurate flow information collected from both the blowdown and make- up water lines can be used to calculate rates for evaporation, cycles of concentration and cooling water chemical treatment rates.

Tracking these related factors is important to the assessment and improvement of a system's water treatment program. For example, maintaining the highest cycles of concentration can offer significant savings on cooling water treatment costs. Having accurate blowdown and make-up flow rate data is essential in achieving this goal. The flow data translates into savings on chemicals, sewage fees and associated energy costs related to cooling water usage.

Flow Meter Technologies

Different flow meter technologies have their advantages and disadvantages, depending on the fluid

and application. Cooling tower and HVAC systems require the ability to measure flow to +0.5% accuracy in high instrumentation is tight, and low maintenance and long life are essential.

McCrometer's FPI Mag® Electromagnetic Flow Meter meets the accuracy requirement in water for cooling tower service with its accurate sensing across the full diameter of the pipe. The meter installs without cutting pipe, welding flanges, de-watering lines or interrupting service. This reduces installation time and costs by up to 45 percent over traditional full pipe flow meter installations.

When choosing a new or replacement flow meter for service in cooling tower systems, be sure to consider the meter's accuracy, ease of installation, maintenance requirements and life of the instrument. Flow measurement at multiple points in cooling tower and HVAC systems is a best industry practice to minimize: water consumption, energy expenses, the cost of water treatment consumables and repairs to pumps and other equipment.

Capillary Source Heater Assembly

APCI heater
APCI heater from BCE (Belilove Company-Engineers)
Atmospheric pressure chemical ionization (APCI) a widely used ionization technique in mass spectrometry, is the ability to easily ionize and detect non-polar or slightly polar species.

The APCI heater has a Resistance Temperature Detector (RTD) built into it. The heater assembly has a .016” ID capillary tube in the center of the heater axis. The maximum operating temperature is up to 400°C. This assembly comes complete with the connector plug.

The APCI sample is typically dissolved in a solvent and pumped through a heated capillary. Nitrogen gas is introduced the gaseous solvent is heated up to 400°C the sample is then ionized by corona discharge.

How Industrial Magnetic Level Indicators (MLIs) Work in Process Control Applications

Magnetically coupled liquid level indicators

Magnetically coupled liquid level indicators (MLIs) are in widespread use throughout today's process industries.

Originally designed as an alternative to site and gage glass devices, MLI’s are now commonly utilized in both new construction and plant expansions. Orion Instruments magnetic level indicators are precision engineered and manufactured to indicate liquid level accurately, reliably, and continuously.

As shown in the video below, a float designed for the specific gravity of the process liquid travels inside the MLI chamber tracking the rise and fall of the process media.

This float contains an internal magnetic assembly that couples with the external visual indicator. The individual “flags” or “flippers” rotate 180 degrees as the level rises and falls, indicating the position of the liquid inside the MLI, and therefore, indicating the level of the liquid in the vessel.

These units are completely sealed and require little to no periodic maintenance. MLI’s also eliminate fugitive emission and glass breakage concerns common with site and gage glasses.

To complement these products, Orion Instrument produces a complete range of level switches and transmitters to further expand the control and alarm capability of the MLI.

Belilove Company-Engineers Gains ITAR Registration. So What's ITAR?

BCE (Belilove Company-Engineers) is ITAR registered.
The International Traffic in Arms Regulations, known as ITAR, are export control regulations run by the US Department of State. BCE is now ITAR registered. So what does this mean?

Understanding and complying with The International Traffic in Arms Regulations (ITAR) is necessary for companies in the supply chain to operate efficiently and expand business opportunities world-wide.

The U.S. Government requires all companies who manufacture, export, or broker defense related articles, defense related services, or technical data to be ITAR compliant. In as much, compliance with the continuously evolving export regulations is essential for any company that does business with manufacturers or contractors who compete in the global marketplace.

ITAR is designed to help ensure that defense related technology does not end up in enemy hands. ITAR relates directly to defense-related applications.  Items specifically designed or otherwise intended for military end-use are listed on the United States Munitions List (USML) and are therefore controlled by International Traffic in Arms Regulations (ITAR). The program is administered by the Directorate of Defense Trade Controls (DDTC) at the State Department.

Products, services, and information all fall under ITAR regulations, with the most notable items being “Significant Military Equipment (SME)”. These are the most controlled. Examples are tanks, ships, helicopters, and explosives. However, there are many other "not so obvious" items listed on the USML,  or used in the supply chain, and providers of these articles must follow ITAR as well.

To be ITAR COMPLIANT, a company needs to register with the Directorate of Defense Trade Controls and fully understand what is required for compliance. The company must understand and abide by the ITAR as it applies to any of their United States Munitions List related goods or services, and the company certifies that they comply with ITAR when they providing materials or services to a USML prime exporter.
