Oxygen for Life. To what extent it's essential to monitor it for a safe working place ? Oxygen concentration in Air is 21%. However oxygen can be displaced by other gases depending on the environment you are in. Oxygen displacement or deficiency shall be due to leaking materials from storage tanks, natural gas lines, process valves etc.  Decomposing organic matter, such as animal, human or plant waste, produces methane, carbon monoxide, carbon dioxide and hydrogen sulfide that displace oxygen.  When Oxygen level falls below 19.5%, health hazards may occur, with few breaths of oxygen deficient air leading to suffocation or even unconsciousness.  Confined spaces prohibit natural ventilation preventing gases from escaping. Explosive and toxic gases, including hydrogen sulfide and carbon monoxide, combined with a lack of oxygen, are the cause of most confined space accidents. By tracking Oxygen levels, gas leaks can be detected eventhough leaking gas cannot be see...

FLARE GAS. Excess hydrocarbon gases which cannot be recovered or recycled is burnt off in the flare system minimizing the impact on environment.  Biggest challenge is measurement of Flow of  Flare Gas as it is characterized by Low and High flow requiring high turn-down ratio, Unknown gas composition, Large pipe size, Limited straight run requirement,  Hazardous Area Approval etc. While the source of the flared gas is typically a leaking valve, identifying which valve and from which operating unit is very critical, difficult and time consuming. Ultrasonic flowmeter can measure the speed of sound of the gas. With sound velocity, temperature and pressure, the meter can determine the molecular weight and composition of the flared gas thereby enabling the operators identify the potential sources of flaring. Interesting isn't it? Flare gas flow meter is a key Instrument to signal abnormal process changes, early leak detection etc., while providing flow measurement d...

Hydrogen and not Air is used in Large generators for cooling. Do you know why? Larger generators produced more heat and also introduce windage losses caused by  wind resistance and friction on the generator shaft. Hydrogen has a thermal conductivity much higher than air and  a much lower  viscosity than air.  Hydrogen is safe to use and won't support combustion if you can maintain its purity above 90%. Also as the concentration of Hydrogen as a coolant increases the cooling efficiency of the generator also increases. During startup Air is replaced with CO2 and then CO2 is replaced with Hydrogen in a way to ensure Air is not in direct contact with Hydrogen. And during maintenance the reverse is followed to fill it with Air for safe working of personnel. Thermal conductivity analyzers are available to monitor the concentrations of Hydrogen and CO2 in Air to enable efficient and quicker Startup, Shutdown and Maintenance operations. Happy Reading.

Do you keep your car running in your garage or in a closed parking place...Never do that again. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is poisonous to humans. It is known as the “silent killer” because humans cannot tell when they are around it, but it is very dangerous and deadly. Exposure occurs by breathing air that contains carbon monoxide. Carbon monoxide is released directly from vehicle tailpipes while the engine is running. Carbon monoxide present in motor-vehicle exhaust can accumulate in garages, enclosed parking facilities, service stations, and vehicle-repair facilities. Other than this Carbon monoxide can be produced by any fuel-burning device. Main sources are your furnace, dryer vent in a drying machine, fireplace or chimney, etc. It is important to have these sources regularly serviced and cleaned by a professional to help prevent a CO leak that could lead to carbon monoxide poisoning. The carbon monoxide detector is a safety d...

Thermal validation is the process of validating and qualifying equipment and storage facilities to prove that they will create and maintain the temperatures they are designed for. A broad spectrum of instruments and processes require thermal validation. It can be a simple temperature map of laboratory Incubator, Freezer, Furnace or a full fledged autoclave unit. A typical thermal validation setup would include a thermocouple/RTD or a set of sensors with Traceable accuracy and a Datalogger. Sensors would require pre and post calibration records which is done typically with Dry Block Calibrators. Wireless dataloggers with Integral sensors for Temperature can make the Thermal Validation much easier. With Multiple dataloggers, Pharma Industries can execute multiple thermal mapping exercises at once. Validation software should be compliant to 21 CFR Part 11 and be validated. Some software goes further allowing complex calculations to be performed with a clear pass and fail crite...

Line of Sight and WirelessHART... WirelessHART is a radio communications protocol that adds wireless capabilities to the HART protocol while maintaining compatibility with existing HART devices, commands, and tools. WirelessHART utilizes a time synchronized, self-organizing, and self-healing mesh architecture that supports operation in the 2.4 GHz ISM license free band. Wireless HART has several advantages.. its highly encrypted, it's license-free and, most importantly, you are free from the clutches of wire. If an obstruction is introduced into the network, data will continue to flow because the device already has other established paths. Gateways interface with existing host systems via LAN or serial communications using industry standard protocols including OPC DA, Modbus®TCP/IP, Ethernet/IP & HART-IP, and Modbus RTU It enables a faster way to get the measurements to the central Host. If you have challenges running the wires from the measurement points but have a...

Water balance estimation is an important tool to assess the current status and trends in water resource availability in an area over a specific period of time.  When it comes to a specific industry a water balance chart compares the total water supplied to the site, the actual water consumed within all the water end uses in the site, and the total water leaving the site. This will help to identify areas of significant water usage and problem areas, including leaks and uncontrolled losses. Industry is demanding ever-greater volumes of water, while at the same time producing wastes and effluents, which in many places taint and damage the quality of this precious resource on which all life depends.  Water balance can help robust water accounting, monitoring, optimum operating and management in industrial parks.  Furthermore, performance indicators could evolve to a useful tool for leading to more systematic analysis of the impact of industrial design and manageme...

Plant Asset Maintenance and Protection starts from Lubrication.  Read to know more.. Lubricants form a thin layer to a level of micron between rolling Element and race thereby keeping the element separated and minimizing the contact in a Rolling Element Bearing. The lubricating fluid also helps in removing the heat that is generated by shearing. Insufficient lubrication allows metal to metal contact resulting in wear and tear. Lubricants are chosen based on the loads and operating temperature. Excessive lubrication is also no good resulting in high Temperature due to shearing stresses leading to bearing failure. Clean Lubricant ensures long Bearing Life. Even  micron-sized debris that gets trapped can result in the formation of a small pit in the race resulting in fatigue crack. If the particle is big then it creates a groove in the Race surface. Its ideal to monitor lubrication level, temperature and vibration on a continuous basis to predict problems well in adva...

How do you manage your most expensive Utility in your Plant ? Do you know what constitutes a major pie in your energy consumption chart ? Air compressors play an important role in any facility, and their energy consumption can make up a significant percentage of total energy use. Since compressed air is often the most expensive utility, operating costs can be significant. This is why, in recent years, increasing numbers of plants and facilities have started taking steps to reduce the amount of energy used by air compressors. What Smart Plant Operators do to reduce the energy used by air compressors? 1. Create and manage an air compressor operating schedule. Identify idle periods when the compressor can be shutdown. Automatic data logging and analysis can help a scientific approach. 2. Fix existing system leaks. Large leaks will be audible, while smaller leaks will need to be identified by ultrasonic leak detection technology. A periodic Air Audit will help. 3. Drawing cool ...
