Technical: PIMS LP Model Calibration, Improvements, and Training
Ecopetrol sought to improve its PIMS-based linear program (LP) models for conducting its refining and petrochemicals short- and long-range planning activities.
Area of Expertise:
Technical
Project Example
Economic Modelling / Optimisation – Ecopetrol
Context
- DAI consultants were contracted to deliver the models while working for Nexidea, Inc. 
- The services were performed from June 2012 to April 2013 for a value of USD 1,326,841. 
Objective – Integrated PIMS Model
Develop an integrated LP model (PIMS) for conducting refining and petrochemicals short- and long-range planning activities.
Approach
- The consultants worked as a team with client personnel to build five weight-based LP models which - tracked the speciation of naphtha and lighter components in the feeds and process correlations 
- included documented yield and property correlations derived from SmartRef process unit models including benchmarking of existing process operations. 
 
- The project team provided two, one-week training courses to 20 personnel toward the on-going development and use of the models along with certifications. 
- The project team and client also identified earnings improvement opportunities of >USD 40 million / year 
Outcome
The team received a perfect performance score (100 points / 100 points) for the project.
