The angular coordinate method allows to simplify the multi-level operation of the compressor to a one-dimensional visualization of the safe operating zone, presenting it as a direct comparison of the process variable with the set value, which is the most common and convenient practice for plant operators monitoring processes in the DCS.

Reducing Wellhead Fugitive Emissions with Electric Actuators
For producers, transporters, and distributors in the hydrocarbon value chain, Emerson provides a portfolio of proven fugitive emissions solutions.
Control Valves for Ammonia Production Efficiency
Control valves are critical in the applications within the ammonia production process. Some applications are severe services that could cause challenges to the valve operation, impacting the process efficiency and may disrupt the production or even damage the equipment.
Role of Digital Valve Controllers in Modern Process Safety
Valves used in process safety applications remain static for much of their existence in a manufacturing or production process. Digital valve controllers can play an essential role in ensuring these valves operate as they should when called upon in an abnormal situation.
Optimizing Water Usage in Ore Mining Operations
A white paper, High-Performance Control Valves for Water Addition Processes in Ore Mining, highlights the importance of valve selection in reducing operational and maintenance costs, waste, and water usage.
Recommended LNG Process Valves, Actuators and Regulators
Selecting the proper final elements—valves, regulators, actuators—helps to enhance equipment reliability and improve LNG and regasification plants safety—ultimately driving cost savings and operational excellence.
Enhancing Safety with Advanced Pressure Relief Valve Technologies
Pressure relief valves (PRVs) are crucial for preventing unsafe overpressure conditions in production processes. Historically unmonitored, these devices now benefit from advanced monitoring solutions that transform data into actionable insights. Explore how technologies like wireless acoustic transmitters and differential pressure transmitters are revolutionizing PRV monitoring, enhancing safety, and improving regulatory reporting.
Calculations for Sizing Control Valves
A Fisher brand technical paper on Valve Sizing Calculations shows the traditional and standardized calculations for properly sizing pressure regulators and valves.
When is a SIL Suitability Rating Required for Final Control Elements?
Riyaz Ali provides clarity on when to assign the SIL suitability for valves used in different scenarios (process control vs. safety shutdown) and establish criteria to assign SIL applicability for the “Final Element”.
Supercritical Control Valve Selection
Supercritical fluids are often found in carbon capture, ethylene, and hydrogen refining processes, and they pose unique equipment selection challenges, particularly for control valves. Our article on pages 45-50 in the February issue of Hydrocarbon Engineering, titled...
Rendere più redditizi gli hub regionali per la cattura e lo stoccaggio del carbonio
L’articolo tratta dei poli regionali di cattura e stoccaggio del carbonio (CCS) e delle tecnologie avanzate che possono ottimizzare questi processi per ridurre i costi e migliorare l’efficienza. I poli CCS permettono a più emettitori di CO2 di condividere infrastrutture, riducendo i costi complessivi. Tuttavia, i costi rimangono elevati, specialmente in termini di energia necessaria per catturare e comprimere la CO2.
Una tecnologia matura per la cattura della CO2 è l’assorbimento post-combustione basato su ammine, che ha bisogno di un ampio monitoraggio e controllo per bilanciare efficienza e costi. Il monitoraggio online e l’automazione sofisticata, come i misuratori di portata e densità Coriolis, migliorano l’efficienza del processo.
Dopo la cattura, la CO2 viene liquefatta e trasportata tramite condotte, e per mantenere la sua stabilità sono necessari compressori affidabili e sistemi di monitoraggio per rilevare eventuali perdite. Le soluzioni di automazione, inclusi sensori wireless e sistemi di controllo avanzati, sono cruciali per prevenire perdite e garantire il funzionamento sicuro delle infrastrutture.
Per le reti di condotte condivise, è essenziale misurare con precisione la composizione della CO2 e le impurità, utilizzando analizzatori di gas avanzati per prevenire danni. Le stazioni di integrità della CO2 comprendono una serie di soluzioni di automazione per monitorare e garantire la qualità della CO2 trasportata.
Infine, il successo dei progetti di stoccaggio sotterraneo della CO2 dipende da valutazioni accurate della capacità di stoccaggio, che possono essere migliorate con software avanzati di esplorazione e produzione e soluzioni di gemellaggio digitale per una modellazione precisa degli ambienti fisici.
Hacer más viables los centros regionales de captura y almacenamiento de carbono
Los centros regionales de captura y almacenamiento de carbono (CAC) pueden ser una propuesta económicamente atractiva, ya que permiten a múltiples emisores de CO2 de una zona -como centrales eléctricas, plantas químicas y acerías- compartir infraestructuras y tuberías. Aun así, la CAC sigue implicando costes significativos, ya que la captura y compresión de CO2 requiere un gran consumo de energía.
