AspenTech, a global leader in asset optimisation software, has announced that it has expanded its 12-year partnership with St1 Refinery AB, part of St1 Nordic Oy Group.

The refinery, situated in Gothenburg, Sweden, is deploying AspenTech solutions to provide a vertically integrated set of production optimisation solutions – from operational planning to real-time control of critical equipment. This will allow an increase in operating margins while improving energy efficiency and thereby reducing carbon dioxide (CO2) emissions.

St1 produces and invests in sustainable energy production in various areas, together with investments in energy transition of its traditional refinery. It has a long-term advanced renewable fuels strategy which includes biorefineries. One is currently under construction at the Gothenburg refinery. A long-term user of AspenTech’s Planning & Scheduling solutions, St1 recently migrated to Aspen Unified PIMS and have now agreed to extend the partnership with the deployment of AspenTech’s advanced process control software Aspen DMC3TM and its dynamic optimisation software, Aspen GDOTTM, across the Gothenburg site.

Miika Eerola, managing director, St1 Refinery commented: “It is important that our refinery continues modernising to maintain a positive long-term future and provide opportunity for the next generation. Our collaboration with AspenTech enables improvements across many critical elements in our renewables strategy, including equipment efficiencies resulting in less energy, hydrogen optimisation including future biogas feedstock and refinery optimisation to maximise benefits with fuels production.”

“St1 Refinery’s investment in advanced renewable fuels and biorefining puts them at the forefront of an industry driving a more sustainable future. We are delighted to be a key part of their strategy to meet emission targets, building on our partnership established over a decade ago,” said John Hague, executive vice president of operations at AspenTech.

With a combination of AspenTech’s production optimisation and performance engineering solutions in place, St1 Refinery is equipped with data and solutions to make quicker, more accurate decisions that help them achieve their profitability goals while moving them significantly along the path on their energy transition journey.
