    DeltaV Blog: Migrating Legacy PLC-5s to DeltaV

    Way back in the mid-1980’s, when I was a newly-minted engineer working oil & gas production projects offshore in the Gulf of Mexico, a new series of PLCs came on the scene to replace the Allen-Bradley PLC-2’s we had been using. They were the PLC-5 series. Javier DeLuna Now, more than 30 years old, the CPUs used in these PLCs were placed into end of life status which meant no further factory support for the CPUs as...

    Valves Blog: Valve Condition Monitoring Connected Services

    One path in digital transformation programs is to drive reliability improvements of plant assets by moving from reactive maintenance to condition based maintenance of the equipment. Saurabh Pathak I caught up with Emerson’s Saurabh Pathak who shared a case study with me of a large, Middle Eastern natural gas transportation & distribution company. This company had a continuous improvement program to improve asset...

    Flow Blog: Accurate and Reliable Orifice Meters

    Steve Ifft A few weeks ago at the Emerson Exchange conference in Nashville, I wrote a real-time blog post on an experts’ session on flow measurement technologies . Since no one flow measurement technology excels for all applications, this session proved to be a lively & humorous one where each of the Emerson experts extolled the virtues of their flow metering technology and the shortcomings of some of the other technologies...

    Valves Blog: Approaches to Partial Stroke Testing Safety Valves

    The safety valve within a safety instrumented function (SIF) must be tested regularly to help assure proper operation in the event of a safety demand. Operators usually perform an offline full stroke test during a scheduled shutdown because of the impact of this test on the process. But when a SIF (a.k.a. safety loop) requires more frequent testing, users can perform a partial stroke test (PST) , per the global IEC 61511...

    Level Blog: Successfully Applying Non-Contacting Radar in Black Liquor Mixing Tanks

    In the Kraft pulping process, wood fibers are separated, and resinous materials removed, using an alkaline (typically sodium hydroxide and sodium sulfide) cooking liquor, also known as white liquor. This process converts wood into cellulosic pulp used in the papermaking process. This digesting process turns the white liquor into black liquor, which contains : …lignin fragments, carbohydrates from the breakdown of...

    Level Blog: Improving Floating Roof Tank Performance

    Christoffer Hoffmann Bulk liquid storage terminals are a critical component in the energy industry supply chain between production and distribution. Floating roof tanks are commonly used to avoid having a vapor space or ullage between the liquid level and roof found in fixed-roof tanks. A Storage Terminals magazine article, Staying on the Radar , shared some thoughts from Emerson’s Christoffer Hoffmann on avoiding...
