Petrochemical complex replaced existing flow meters with Coriolis and vortex units to achieve greater reliability and accuracy The switch cut product and steam losses, boosted energy efficiency and provided additional benefits.
Multiple sensors measure pressure in different sections of a distillation column. These sensors must work safely and reliably. Optimization requires properly dealing with temperature effects on pressure measurements.
In plant operations, one device that can represent significant cost is the sensor, particularly one used in a harsh application. Such sensors are critical probes that gather and deliver key data, and are often exposed to or immersed in corrosive solutions and subjected to high operating ...
Temperature plays a critical role in most processes, so using the right temperature sensor is important. Choosing between RTDs and thermocouples requires consideration of a variety of factors from accuracy to durability.
Applications benefit from more precise dosing and improved control. Read this article to learn why.
Level measurement can be a simple issue with numerous solutions. Measuring the height of the material in a vessel is merely an interface issue that can be resolved in a variety of ways.
Process Engineering: Accurate measurements under controlled conditions form the cornerstone of the development of methods for the successful design of heat transfer equipment.
Find the Real Maximum Pressure Vessels -- Always consider static head when assessing pressure vessels.
Stop Loops Driving You Round the Bend -- Practical pointers trump educators' edicts for real-world process control.
Pressure gauges are an often-overlooked defense mechanism against accidents. At many plants a significant number of these gauges are broken, damaged or misapplied. Here are eight primary culprits.
Effectively monitor data to make your plant more energy efficient and reliable
Monitoring the flow of powders and other solids often is crucial for operations but can be trickier than monitoring fluids. Here’s a rundown of some significant developments in technology to measure such materials.
Liquid level commonly is measured using displacers, floats or differential pressure. Understanding the physics behind the measurement is crucial for knowing how an instrument may be operating when facing unusual conditions.
A variety of issues can undermine the accuracy, reliability and service life of pH sensors. Calibration is essential and can provide important insights. Here’re guidelines on how to identify and address common problems.
A Korean petrochemical complex accumulates water in its naphtha storage tanks. It manually drained the tanks to remove the water but this was tedious and imprecise. Installing a conductivity meter enabled more accurate and less-labor-intensive draining.
Wanting a wireless flow transmitter at an elevated point in an extremely hot environment but concerned about the need for frequent battery replacement, an Ohio plant instead turned to a thermoelectric energy harvester
Precise and repeatable readings require proper interaction of the key elements in the system. Here’re pointers on how to get accurate temperature measurements while avoiding common problems and minimizing maintenance.
This article looks at six technologies mechanical floats and displacers, differential pressure, capacitance, ultrasonic, radar, and guided wave radar that are used most often for automated control, and provides practical guidance for choosing among them.
This month's quick poll wants to know what measurements cause the most headaches at your chemical facility.
This level-measurement technology suits many applications. Like any level-monitoring option, it has both advantages and disadvantages. This article discusses what to consider in determining whether or not to use guided-wave-radar level instruments.
Product quality often varies between different operating shifts. Today, the availability of more process data and better connectivity can go a long way toward addressing such variability. Electronic shift logs and bringing in business data also can help.
Picking a pH sensor can seem an overwhelming task. Deciding which options are needed can be confusing. No single sensor always is best for all plant applications. This article discusses some important factors to consider during the selection process.
