HP Integration Strategies: Recent trends shape the future of DCS
Several trends have already impacted the distributed control system (DCS) market and are likely to continue over the next few years. These include both product- and technology-related trends and gener..
Use a systematized approach of good practices in pygas hydrogenation via APC
APC with inferential modeling was successfully applied to pygas hydrogenation units. The lengthening of the catalyst run length limits downtime for both the pygas unit and upstream units such as the steam cracker.
Why don’t we properly train control engineers?
While there are managers in the process industry that see training control engineers as a “no-brainer,” these are very much in the minority. They may send staff on courses covering configura..
Consider automated fault detection systems to improve facility reliability
Automated fault detection and diagnosis systems (AFDDSs) are well established in many consumer and industrial sectors.1 The conventional limit-value based (high/low alarms) fault detection and diagnos..
Optimize desulfurization of gasoline via advanced process control techniques
This case history describes the development of the inferential models used in open-loop and closed-loop applications, laboratory and analyzer update mechanisms, and APC model generation.
Apply new pump-drive software to test performance
Process control schemes involving fluid-flow machinery with traditional adjustable speed drives (ASDs) or modules encounter limitations such as control flexibility and accuracy. In this context, the t..
Emerson to supply automation for Vopak terminals
Under the agreement, Emerson will design, configure, and implement digital automation systems for all new automation projects at Vopak terminals, as well as provide ongoing support services for new and existing automation systems. Financial terms of the agreement were not disclosed.
Tyco signs global agreement with Shell to provide pressure relief valves
The five-year agreement covers Crosby and Anderson Greenwood direct acting and pilot-operated pressure relief valves, line block relief valves and supporting services for all of Shell's global operations. During 2011, Tyco was also selected by Shell to provide butterfly valves in a similar arrangement.
Successful fouling control hinges on effective monitoring
Equipment reliability, processing flexibility and energy conservation are key objectives for modern refineries. Refiners today are routinely using lower quality, more difficult to process feedstocks t..
HP Automation Safety: ‘Sticktion’: A dangerous failure mode
I set a wet glass on the old wooden kitchen table at our home. It sat there all night. The next morning, when I went to grab the glass, it stuck to the table. Yes, this event has happened before. But,..
