Perstorp to boost carboxylic acid production capacity by 2024

Sweden’s leading specialty chemicals company Perstorp announced plans to build additional production capacity of around 70,000 tonnes per year of carboxylic acids which will be onstream by 2024. The investment will enable Perstorp to increase output significantly and strengthen its  position as the sustainable solutions provider. 

Increased capacity will meet growing demand in various high-value applications,  including non-phthalate plasticizers for PVC, engineered fluids for applications such as refrigeration lubricants, and various  propionates used in food preservation and carboxylic acids for use in animal feed gut health and preservation products. Most of  the output will be used in downstream production operated by Perstorp itself. 

Perstorp will build a new plant on the site of its existing carboxylic acid production operation in Stenungsund, Sweden. Like the  original unit, it will be capable of producing acids from C3 to C9 chemistry, significantly strengthening the company’s portfolio.  Both plants will be fully integrated into Perstorp’s Oxo production platform. 

The decision to go ahead with the capacity expansion comes during a period of high growth for Perstorp, which has maintained  a strong position in its key markets despite disruption caused by the Covid-19 pandemic. “The expansion fits with our strategy  for growth and an increased emphasis on specialty products, and will reinforce our pioneering position in sustainable solutions for our key focus segments,” said Betty Lu, vice president for Oxo chemicals at Perstorp.  

“I am glad that our acid capacity expansion is now back on track, after a temporary delay due to Covid. This capacity  investment will remove our last bottleneck and enable us to grow our unique non-phthalate plasticizer Pevalenand Pevalen  Pro unconstrained in the coming years.” 

Perstorp has a unique position among plasticizer producers in offering Pevalen, a high-performance polyolester plasticizer, which is ideal  for sensitive close-to-consumer applications such as coated fabric and films and sheets. Pevalen meets growing demand for new generation plasticizers and has performance advantages over some of the most commonly used plasticizer solutions in terms of efficiency and UV stability. 

Perstorp also uses carboxylic acids for its in-house production of various grades of food preservative (ProfinaCP) and animal  feed preservative (ProSidMI 208). It is the only company in the world making these products with upstream integration.
