Topic: Instrumentation

Control performance supervision enhances revamp
ChemicalProcessing.com
Upgraded ethylene cracker achieves targeted production rates in record time

Build reliability in during design
ChemicalProcessing.com
Instrumentation that promises to improve reliability may not always be what they seem. You have to consider whether a site can properly maintain sophisticated instruments.

Improve control loop performance
ChemicalProcessing.com
Specification of control valves doesn’t adequately emphasize the very basic requirement that valve position respond in a timely manner or even at all — leading to process variability.

Blind Transmitters: A return to the basics
ChemicalProcessing.com
Analog transmitters easily send process measurements from different areas in a plant to a central PLC where process control decisions can be made based on transmitter feedback. Analog transmitters are great cost-saving alternatives to single-point controllers. In situations where multiple sensing locations are required, single point controllers’ costs can add up quickly.

White Papers: In depth research


Title Author Date
Improve plant operations with process control Honeywell 02/25/2008
Operations, startups, shutdowns, emergency procedures, bringing equipment to intermediate safe operational states and changeovers can all be significantly impacted by your refineries’ procedural operations. Find out how to improve your operations through process control improvements. 
Improve Plant Safety and Availability through Advanced Measurement Diagnostics Rosemount 12/21/2005
Advanced diagnostics, some of which are available today, will go beyond alarming transmitter failures to actually predict impending failures in the complete measurement system. This will significantly reduce unscheduled shutdowns, and also reduce the risk of onscale failure. 
Measurement Best Practices Rosemount 10/05/2005
This 9-page PDF discusses way in which you can ensure your measurements are accurate, repeatable and reliable. 
Technical handbook from Magnetrol Magnetrol 04/04/2005
This technical handbook from Magnetrol gives important conversions, chemical properties, equivalents and pipe data. 
Theory and practice of pH measurement Rosemount Analytical 01/04/2005
This 43-page guide covers the basic mechanism of pH measurement, the structure of the sensor and its fundamental limitations, and also provides installation, maintenance and troubleshooting guidance. 
Tracing the accuracy of calibration gases 12/29/2004
Calibrating your instruments using specialty gas will only yield results as accurate as your gas mixture. This three-page white paper discusses analytic traceability and how it relates to gas mixture accuracy.  
Selecting Transmitters for Safety Instrumented Systems DuPont Fluoroproducts and Rosemount Inc 08/27/2004
This paper presents best practices that allow the user to quantify the impact of real-world failure causes and to take credit for improvements in system design. Besides selection, it also covers installation and maintenance.
