Aspen Refinery Multi-Blend Optimizer provides off-line blend scheduling and optimization capabilities for gasoline, distillates, fuel oils, and other refined products.  It generates optimal recipes for individual blends or aggregates blends into time partitions.  Aspen Refinery Multi-Blend Optimizer can be implemented standalone or with Aspen Petroleum Scheduler for refinery blend optimization and scheduling. Aspen Refinery Multi-Blend Optimizer is a core element of aspenONE® Planning and Scheduling for Refining and Marketing.

Features

  • Optimal Blending Schedules:  Using an event-based, multi-period, and multi-blending modeling system, optimal blend schedules for short- and/or long-term campaigns are developed.
  • Linear and Nonlinear Modeling: Delivers the automatic generation and simultaneous solution of a mixed-integer, nonlinear model of the entire blending process. Includes complex nonlinear blending correlations, tank constraints, discrete volume and recipe constraints, and all relevant events such as blends, product shipments, intermediate receipts, and tank-to-tank transfers.
  • Common Database:  Shares a common database with Aspen Petroleum Scheduler and uses the same graphical user interface, giving the scheduling staff the same “look and feel” for all activities and enabling them to optimize blending based on an Aspen Petroleum Scheduler schedule.
  • Blend Control Interface:  Allows for a standard automated export of optimized blend recipes to the blend control system.
  • Aspen Blend Model Library (ABML):  Provides a common set of blending correlations that can be shared between Aspen Refinery Multi-Blend Optimizer and other components of the apsenONE Planning & Scheduling solution (e.g., Aspen PIMS™ and Aspen Petroleum Scheduler).  ABML supports calculations for index properties, derived properties, complex properties, interaction coefficients, and client-specific blending correlations. Numerous specifications are supported including EPA RFG, CARBOB, and RBOB.
  • What-If Analysis:  Provides look-ahead feasibility analysis and allows user to easily compare trend data for multiple cases on a single chart for what-if cost comparisons.  

Benefits

  • Increase Collaboration: The integration between Aspen Refinery Multi-Blend Optimizer and Aspen Petroleum Scheduler helps process unit schedulers and blend schedulers stay synchronized, while reducing model maintenance and total cost of ownership.  Additional integration to Aspen PIMS provides collaboration with planners.
  • Improve Margins: By using the optimal combination of components, blend recipe giveaway and blend quality giveaway reductions are realized and overall margins are optimized.
  • Meet Regulatory Requirements: Eliminate off-spec blends and penalties by consistently meeting regulatory requirements.
  • Reduce Supply Chain Costs: Decrease demurrage, inventory holding costs, and component stockouts by making the right blends on first attempt.  Provides greater upgrade of low-volume components.
  • Increase Visibility: Improved interaction with the trading group by providing more valuable information on inventory positions and component requirements.
