Casale awarded fertilizer plant PDP contract


Casale awarded fertilizer plant PDP contract

Casale has signed a process design package (PDP) contract with Daewoo Engineering & Construction Co for two new fertilizer plants. These are being commissioned by Turkmenhimiya, Turkmenistan’s state-owned chemical company, as part of a production complex in Turkmenaba, the country’s second-largest city.

The two new fertilizer plants will manufacture granular ammonium sulphate (AS) and single superphosphate (SSP), respectively. Once completed, the Turkmenaba complex will produce 350,000 t/a of granular SSP using CULTIVA-SPhos, Casale’s proprietary technology for granular SSP production; and 100,000 t/a of AS using CULTIVA-PIPEX, a flexible and proven Casale process technology which is also used for NPK production.

“This latest contract highlights once again the trust in Casale’s process know-how and technology portfolio and confirms the value of our Phosphate and Nitrogen fertilizers portfolio in supporting large-scale fertilizer projects with high agronomic and operational performance,” Casale said in a statement. “We thank Daewoo Engineering & Construction Co. for their confidence and look forward to building a strong and lasting partnership. This collaboration reflects Casale’s commitment to driving sustainable agricultural development and delivering innovative solutions tailored to local market needs.”
