Casale new High Pressure stripper for urea plant

Casale strengthens its presence in the plants of Grupa Azoty PUŁAWY, the Polish leading company in the production of fertilizers.

After the revamping of the Urea plant of Puławy in 2010, followed by the supply of various equipment and interventions for the plant improvement, aimed at increasing its performance and supporting the policy of reducing CO2 emissions undertaken by the Polish group, a new HP stripper made with Uremium 29 components has just been delivered.

Urea plant in PolandScope of this supply is the replacement and modernization of the HP stripper in the synthesis section of the Puławy Urea Plant 2.

Uremium 29 is the new alloy with very high resistance to carbamate induced corrosion that Tubacex, the world leading manufacturer of tubular solutions, has specifically developed for and in cooperation with Casale.

The stripper was built with Casale technology and design at the Villa & Bonaldi workshops, a specialized and experienced Italian manufacturer of H.P. shell and tube heat exchangers for process Industries.

Uremium 29 is recommended for the tubes of HP pressure equipment as well as piping and fittings as it increases reliability and the operating life.

The real industrial tests performed along the last years in several Urea plants have confirmed the enhanced resistance to the most aggressive carbamate corrosion modes.

This is another relevant reference of the Casale experience in the design and supply of strippers, and other HP equipment as well.

With this last delivery to Grupa Azoty Puławy, Casale can now count of more than 35 strippers supplied so far, both new and revamped, with materials of construction ranging from Super-austenitic to Superduplex alloy (e.g Uremium 29) up to more exotic ones such as Titanium and Zirconium.
