A mistake often made with operator displays is to limit the scope of the design work to mimic the process equipment shown on P&IDs and Process Flow Diagrams (PFDs). These initial displays include measurements, valves and final control elements. They include enough of the process equipment and piping so that the process flow can be …

Display content – part 1
Last week the topic was mobile. The discussion focused on different views such as display lists and alarm lists. These views provide the user with information specific to what they are interested in. In the last blog I said I would talk about display content. To begin this discusstion I’ll start with a refinery and …

DeltaV Mobile
In process manufacturing the operator station allows operators to rapidly assess a set of distinct systems or situations under their span-of-responsibility and determine where attention is needed on a moment-by-moment basis. If a problem exists, the features of the operator station directs the operators to displays from which they can troubleshoot and take action. So …

Boot Camp for New Employees
Courses required for an engineering degree are designed to provide the student with a sound technical foundation for work in industry. However, in most cases these courses do not address the terminology and common practices that an engineer must know to design, implement, checkout and commission a process control system. Universities can help bridge this …

Centrifugal Compressor Efficiency – Part 4
Part 1 of the centrifugal compressor efficiency series addressed the measurements and parameters that must be calculated to determine compressor efficiency. In Part 2-3 of this series we examined one way of calculating the enthalpy and entropy of the gas stream at the compressor suction and discharge and isentropic enthalpy for the refrigerant R134a. Once …
