Introduction to Refinery Planning using Aspen PIMS

Course Id:  RPA101   |   Duration:  5.00 day(s)   |   CEUs Awarded:  3.5   |   Level:  Introductory


Course Objective

This course will help you prepare for the certification exam and the exam fee is waived with this course.
Learn how to solve refinery planning problems using Aspen PIMS and Aspen PIMS-Advanced Optimization. This hands-on course has been revised to incorporate problem-based learning by using relevant refinery problems to optimize results. You will not only learn how to use the tools, but you will also learn how to troubleshoot. Videos were created specifically for this class as a helpful tool to use on your job.

This course is designed for new planners and modelers who have 1 year or less experience in Aspen PIMS / Aspen PIMS-AO and need experience in building and optimizing refinery planning models to generate optimum plans.

Course Overview

Develop skills to build refinery Linear Programming (LP) planning models in PIMS to solve and generate optimum plans including evaluating alternative crudes, intermediate feedstocks, outside blendstocks, process units, products, and markets. Review data tables and structures required to build and maintain a model for developing crude distillation architecture, product blending, typical refinery process units, pooling, vector and delta based models, including interpreting and analyzing the LP solutions.

Benefits

  • Learn LP fundamentals
  • Gain familiarity with key Aspen PIMS tables and formats
  • Develop simple Aspen PIMS model and understand how the matrix structures are generated
  • Execute and troubleshoot various case scenarios and analyze information from Aspen PIMS reports
  • Perform basic economic evaluations

Audience

Technical as well as non-technical personnel who have no experience in linear programming. Also, this course provides a person who is knowledgeable in LP (but not necessarily knowledgeable in Aspen PIMS) with a quick way to gain a good understanding of the system.

Approach

  • Instruction on principle topics
  • Hands-on problem solving approach allows the student to gain an understanding of the most important Aspen PIMS data tables, menu options and reports
  • The class problems are designed to illustrate how to model and resolve real world planning problems and also how to interpret and troubleshoot LP solutions

Prerequisites

A basic understanding of Microsoft Windows and a working knowledge of Microsoft Excel, together with a general awareness of the interaction between refining technology operations and planning is strongly suggested.
