Perstorp inaugurates facility for purifying wastewater in Sweden

Sweden’s Perstorp has opened a facility that will enable wastewater from the water treatment plant run by the municipality to be further purified and reused for cooling at the Perstorp Oxo production plant in Stenungsund. This will save 1.1 billion l/year of freshwater.

Each production plant utilises water for various purposes, including serving as a solvent for chemical reactions, a carrier for products, a heat-transfer medium, and for cooling, among other uses. The scarcity around fresh water is present everywhere in the world, and the chemical industry have the opportunity and responsibility to create solutions when it comes to reducing the freshwater consumption.

Perstorp says it invested in this project in Stenungsund and now with this facility fully up and running it will save fresh water every year. This is an investment that Perstorp plan to implement at more sites around the world, to reduce freshwater consumption.

The recycled water will be used for production of renewable hydrogen via electrolysis for Perstorp’s transition project Project Air, as well as for other strategic investments.

The project is a key enabler to combining business growth and sustainable development, and to ensure a future water supply for the Stenungsund plant.

It adds that the 30% decrease in fresh water usage aligns with Perstorp’s long term ambition to become Finite Material Neutrality.

Specialty chemicals innovator Perstorp is planning large-scale production of sustainable methanol from captured carbon dioxide and other residue streams. This could contribute substantially towards a climate-neutral industry. Project AIR, which Perstorp has created with partners, has been approved for the next level of evaluation from the EU Innovation Fund, one of the world’s largest funding programmes for the demonstration of innovative low-carbon technologies. “The positive response from EU Innovation Fund means that we are one step closer to finalising our ambition to become Finite Material Neutral. Project AIR is a concrete example of the transition towards a circular economy and of how significant CO2 emission reductions could be achieved by utilizing existing resources and closing loops,” said Perstorp’s President and CEO, Jan Secher. Project AIR is a large-scale project that by 2025 will decrease annual carbon emissions into the atmosphere by half a million tons. This will be accomplished by building the world’s largest Carbon Capture and Utilisation Unit on Perstorp’s site in Stenungsund, Sweden. Using a new electrolysis plant and taking biogas as a source, it will produce 200,000 tonnes/year of sustainable methanol, enabling the supply of sustainable chemical products to a large variety of sectors and end products. Perstorp, together with partners Fortum and Uniper, has applied for support for Project AIR from the EU Innovation Fund. In an initial evaluation from the Fund, Project AIR received the highest possible score on the categories GHG Avoidance and Degree of Innovation, obtaining in total 14 out of 15 possible points. Project AIR has thereby been chosen to be further evaluated for funding. In its evaluation of Project AIR, the EU Innovation Fund says the proposed large-scale sustainable production of methanol demonstrates, for the first time, increased flexibility and efficiency in using different raw materials (e.g. bio-methane, refinery tail gas, CO2 effluent streams). “In addition, it also uses the recycled carbon sources together with captured CO2 for methanol circular production,” it states. “Furthermore, the proposed plant will use waste water instead of municipal water as a feedstock in the electrolysis station. Waste water is not used as a feedstock in any other commercial electrolysers. The proposal represents breakthrough innovation.” “Moreover, the integration processes, manufacturing, control and operations of the project have not been demonstrated elsewhere; this is a first of a kind and is a breakthrough. This is excellent.” A final decision on what projects will be funded by the EU Innovation Fund is expected later this year.
