Casale new high pressure stripper for Urea plant in Russia


30 June 2021

Novomoskovsk Azot (Russia), one of the major  producers of nitrogen fertilizers worldwide and the first  in Russia for urea volumes, with which Casale has already carried out several revamping projects in the past, has installed an HP stripper supplied by Casale and made with components in Uremium 29. Uremium 29 is the new alloy with impressive resistance to carbamate-induced corrosion that Tubacex - the world leading manufacturer of tubular solutions - has specifically developed for, and in cooperation with, Casale. Uremium 29 has demonstrated an excellent resistance to the most aggressive, carbamate-induced corrosion modes and it is used in industrial applications. Its outstanding mechanical and anti-corrosive properties makes it particularly fit for the tubes of high-pressure equipment as well as for piping and fittings and, in general, all situations where a high degree of reliability and a long operating life are critical factors for sustained, trouble-free operation of any urea plant. Leveraging Casale know-how and experience, this stripper - the 4th of this kind -  has 25% more tubes than the previous one, keeping the same external volume and weight. The remarkable improvement is the result of a careful  geometry optimization and the use of high-strength Carbon Steel  for all pressure resistant parts, which allow to reduce the wall thickness.
