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:
Economic Modelling / Optimisation – Ecopetrol
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.
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
The team received a perfect performance score (100 points / 100 points) for the project.
