Benefits of TDL Over Extractive Measurement

Benefits of TDL Over Extractive Measurement
 Monitoring NH3 using extractive sampling is difficult. The sample must be kept above 290oC (554oF) to prevent formation of ABS and sulfuric acid, both of which damage the sampling and analytical equipment. Without direct gas analysis, many parameters will influence the NH3 measurement, including inlet NOx concentration, fuel composition and c...

What Is The Area Coverage Of My Gas Detector?

tips-from-the-field-DMS
The area coverage of a point combustible or toxic gas detector is, quite simply, limited to the opening of the gas sensor housing. Point gas detectors do not provide an "area coverage" because they can only respond to gas that travels to the gas sensor and enters the sensor housing. Consequently, the quantity of point gas detectors and wh...

Servomex - Extracting The Benefits Of Analyzer Remote Mounting

tips-from-the-field-DMS
Remote mounting is the solution in situations where the flange mount for your oxygen and combustibles analyzer is too hot for equipment, or the location is difficult to access or dangerous for personnel. In remote mounting, the sensor head is situated on a panel or cabinet away from the process, and is connected to the sample point via an insulated...

Comparison of Gas Analysis Technologies in Control Fired Heaters

Comparison of Gas Analysis Technologies in Control Fired Heaters
Fired heaters are integral to hydrocarbon processing (HP). Specifically designed for the reaction of fuel and air to produce extremely high gas temperatures, heaters transfer this energy to potentially highly flammable process fluids via heat exchangers. They consume large quantities of fuel, produce large quantities of emissions and are a potentia...

pH and Conductivity and the 'Elephant' in the Room

tips-from-the-field-DMS
 There's an old story about a group of blind men attempting to describe an elephant by touching different parts of its body. "It's like a snake," said the one who touched its trunk. "No, it's like a fan," said the one who touched its ear. The parable shows how we all tend to base "truth" on our sometimes limited or subjective experience, often...
