MOSCOW (MRC) -- Perstorp plans to have extra capacity of around 70,000 tonnes/year for production of carboxylic acids onstream during 2024. The investment will enable Perstorp to increase output significantly and strengthen its position as the sustainable solutions provider, according to SpecialChem.
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.
Perstorp has a unique position among plasticizer producers in offering Pevalen™, a high-performance polyolester plasticizer, ideal for sensitive close-to-consumer applications such as coated fabric and films and sheets. Pevalen™ meets growing calls 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 (Profina CP) and animal feed preservative (ProSid MI 208). It is the only company in the world making these products with upstream integration. Valmira Ozten, vice president business manager for formates & propionates at Perstorp, says “the company is witnessing strong growth in demand for both Profina and ProSid.”
As a result, the company is planning to significantly increase production capacity for calcium propionate, which is currently located in Castellanza, near Milan, Italy. New capacity could be onstream in early 2024. Various sites are under consideration. Perstorp markets its calcium propionates in numerous countries around the world.
As MRC reported previously, in December 2021, Perstorp, the world leader in the production of Trimethylolpropane (TMP), ramped up the capacity to meet growing demand from the European market. TMP is used to enhance the properties of numerous materials. Common applications include the use in saturated polyesters for coil coatings, polyurethanes for coatings and elastomers, acrylic acid esters for radiation curing, esters for synthetic lubricants, and for the surface treatment of pigments.
