Multiphase flow through pipes is characterized by the flow regime, liquid hold-up and pressure gradient. Accurate prediction of these flow attributes is necessary for designing and maintaining pipelines and flowlines in the oil and gas industry. Aspen HYSYS provides a number of flow correlations for modeling multiphase pipe flow. To aid the user and provide a basis for comparison, the performance of correlations for different pipeline geometries, fluids, and flow regimes was analyzed. This paper discusses these analyses.

Learn how you can eliminate the need to employ separate third-party tools for pipeline hydraulics by modeling the entire gathering and production system (be it offshore, onshore, topside, etc.) within one tool. Using this new pipeline hydraulics modeling capability, you can optimize the design from a capital and energy perspective, and also ensure the overall safety of the system.

Methanol is a powerful hydrate inhibitor, but adding the correct amount requires knowledge of hydrate formation and inhibition. Aspen HYSYS, you can rely on the accuracy of the Cubic Plus Association (CPA) Equation of State (EOS) for completing calculations around hydrate inhibition and methanol partitioning. Start your 1-day online trial today to take a guided tour and try out the new accuracy of the hydrate inhibition stream analysis tool.

As part of an effort to drive reliability in its refinery operations, Saras turned to Aspen Mtell® prescriptive maintenance to improve equipment uptime and decrease maintenance costs.

AspenTech's Smart Calibration allows you to boost productivity and increase performance by creating accurate production sequences utilizing feedback loops.

AspenTech's Polymers Scheduling enables you to reduce transitions and operational costs using high-fidelity modeling of your unique assets.

Learn how Westlake assesses time sensitive supply chain opportunities, such as accepting a modified customer order, in a matter of minutes using Aspen Plant Scheduler rather than four hours using previous spreadsheet methods.

Learn how a major European chemical producer implemented aspenONE® Supply Chain Management, integrated to their SAP ERP system, and was able to reduce inventories by 20%, achieve 97% on time deliveries, and reduce the number of campaign transitions by 20%.

With polymers scheduling utilizing Aspen Plant Scheduler, companies can improve throughput and reduce the number of transitions while simultaneously achieving high on-time order fulfillment rates. Polymer manufacturers are looking for ways to increase on time order fulfillment, unlock their plants “hidden capacity," and reduce total time spent in transitions. Scheduling with intuitive product wheels and powerful sequence optimization methods assists in achieving these goals.

In asset-intensive industries, a single failure of a critical, costly piece of equipment can result in millions of dollars in production losses. In a new report, ARC Advisory Group's Steve Banker describes how optimized production scheduling based on an integrated digital twin maintenance model enables these companies to convert unplanned downtime into less expensive, scheduled maintenance.
