  • Pressure Blog: Batch Repeatability through Instrument Performance and Diagnostics

    Jim Cahill
    Author: Kyle Knutson Batch repeatability is critical in pharmaceutical and biotech manufacturing. Variations between batches that cause deviations require extensive analysis, either in real-time or post-process, to identify how to control and minimize this variation in the future. The consequences of unacceptable batch variation can be anything from extensive maintenance hours, to temporary halts in production or…

  • Flow Blog: Lease Automatic Custody Transfer Components and Operation

    Jim Cahill
    The exchange of crude oil between seller and buyer is known as custody transfer. A simple example of this is the gas pump where you fill up your car. The pump must accurately measure the fuel and determine/collect payment for the amount transferred into your gas tank. Lease Automatic Custody Transfer (LACT) units facilitate this transfer in an automatic way, both in onshore and offshore oil & gas production operations…

  • Flow Blog: Calculating Fluid Density Changes in Foundation Fieldbus Devices

    Jim Cahill
    I received this question on density measurement and wanted to share what I found out. I understand all dP flow measurements are affected by the density of the fluid (liquid or gas) flowing through orifice, annubar, pitot tube, etc. Most dP measurements in process measurements make an assumption of the density of the fluid. I understand the measurement of density is a complicated and expensive. My question to you…

  • Tank Gauging Blog: Helping Develop and Support Industry Standards

    Jim Cahill
    Trade associations play an important role in setting standards for their industry. A great example is the American Petroleum Institute (API) . Just a sampling of important standards we’ve discussed here on the blog includes API 670 – Machinery Protection , API 682 – Pumps—Shaft Sealing Systems for Centrifugal and Rotary Pumps , API 2000 – Venting Atmospheric and Low-Pressure Storage Tanks and API 2350 Overfill Protection…

  • Flow Blog: Repeating Golden Batch Production

    Jim Cahill
    For batch-based processes, the “golden batch” is term often used to describe the ideal batch against which all other batches are compared. In a Control magazine article, Data Analytics in Batch Operations , it is defined: …as the time-based profile of the measurement values that were recorded for a particular batch that met product quality targets. When using this standard, a batch is judge by how closely the golden…

  • Level Blog: Modernizing Tank Farm Measurements

    Jim Cahill
    One of the best applications for wireless instrumentation is in older tank farms. A Tank Storage magazine article, Modernising Old Tank Farms to Meet New Requirements shares why. The article’s author opens: When most tank farms were built, automation was costly. Therefore most storage tanks have a bare minimum of instrumentation and rely heavily on manual checks. Minimal instrumentation is no longer sufficient…

  • Analytical Experts Blog: A New Approach to Online Data Validation

    Rosemount Analytical
    By Jeff Gunnell How would you like an online analyzer that, after commissioning, starts up already in perfect calibration? That during its life, checks that it is in calibration without needing test samples? That works for very long periods without maintenance, but when eventually intervention is required, the analyzer raises a flag, gives a description of why maintenance is needed, and explains exactly what to do?…

  • Level Blog: Improved Mining Safety and Operational Performance through Solids Level Measurement

    Jim Cahill
    Some industries, such as the mining industry, face the challenge of having to measure the level of solids. Unlike liquids, they must content with the peaks and valleys depending on the consistency of the solids being measured. Emerson’s Asael Sharabi shared a story with me about a Canadian copper miner. In their mining process, they crush five different types of ore. The raw ore is passed through a crusher and the crushed…

  • Level Blog: Overfill Prevention Guide for Safer Operations

    Jim Cahill
    As the global supply of oil exceeds demand, not only do we continue to see falling prices, but also tank storage facilities with increasing inventories . From a process automation and management standpoint, having safe and reliable overfill prevention systems are critical for the hazardous materials these storage tanks contain. In a quick 1:04 video, Emerson’s Carl-Johan Roos introduces an overfill prevention guide…

  • Level Blog: Minimizing Safety Risk and Improving Batch Performance

    Jim Cahill
    Articles such as Oil & Gas iQ’s Five Deadliest Onshore Oil & Gas Blasts remind us of the critical importance and focus that is required for process and personnel safety. I lived in New Orleans at the time of one of the five mentioned. The accident occurred during the night and the shock waves from the blast were like someone repeatedly slapping on the windows with open hands. For some facilities, the distance to tank…

  • Flow Blog: Process Automation Nextgen Leaders

    Jim Cahill
    Given the important role that process automation plays in the products that process manufacturers and producers bring to the world, it’s important to have continuity in leadership. Each year, Control Engineering and Plant Engineering magazines recognize Engineering Leaders Under 40 to highlight that this continuity is alive and well. In their 2015 selection of leaders under 40 years of age , they share these statistics…

  • Analytical Experts Blog: Protecting High Risk Turret Systems

    Rosemount Analytical
    By Edward Naranjo, Emerson Process Management, Rosemount Over the last 30 years, the use of FPSOs (Floating, Production, Storage, and Offloading) and other Floating Storage Units (FSUs) has emerged as a key technology to produce oil and natural gas from subsea fields. These vessels can be deployed quickly, and advances in FPSO technology have allowed them to operate in increasingly severe environments and deeper water…
