Acetic acid condenser – steam generator

End user: Rafineria
Location: Polska
Design code: EN 13445, 2014/68/EU

Weight: 23,060 kg
Pressure: 19 bar
Temperature: 175 °C
Medium flammable

Materials: Titanium (Gr. 1 – UNS R50250 – 3.7025 / Gr. 2 – UNS R50400 – 3.7035), austenitic stainless steels, carbon steels

The E-1313 shell and tube heat exchanger manufactured by Polimer Grzegorz Grzesik is responsible for condensing reaction gas (acetic acid) and utilising the steam produced in this process, by transporting it to the turbine. A hydraulic pressure test on the tube side was carried out at 27.5 bar(g).

Tube sheets, heads, and conical and cylindrical chambers were explosively cladded with grade 1 Titanium. Polimer developed its own butt welding technology for connecting titanium cladded carbon steel plates to ensure its hermeticity. 

For heat transfer, 2330 titanium tubes of 7000 mm length were applied and 100% eddy current tested after production and assembly. A helium leak test was performed and the maximum leakage recorded was 10-7 Pa*m3/s.

  • Total weight of empty equipment: 23,060 kg; 
  • Dimensions with chambers: 11,500 mm x 3,500 mm x 3,120 mm; 
  • Equipment was marked CE acc. to Pressure Equipment Directive 2014/68/EU.
