The heat exchangers are all water-cooled, with the cooling water passing through the tubes and the gas or oil through the shell. In this case, they are designed as a floating head with a backing ring and an inlet channel with a removable cover. This allows for easy inspection and maintenance of the cooling water side. The MO cooler is small enough to be integrated into the piping as a fixed tubesheet exchanger without connection covers.
The end customer has extensive historical customer specifications and requested a design according to AD Merkblätter. A vibration analysis was also required. Due to the water quality, the bundles must be manufactured from (22% Cr) Duplex. Integrating the coolers into our client’s package required close cooperation and communication.
Robox successfully combined all these requirements into a package that was delivered to the satisfaction of both the client and the end customer.
These are S&T heat exchangers with a one-pass shell, floating head with backing ring, and removable channel with cover plate. TEMA type AES (_EM for the MO cooler). Shells in carbon steel, tubes in (22% Cr) Duplex. Designed and built according to PED cat. IV/Mod G (gas cooler), Cat. II/Mod. G (LO and SO cooler) and art. 4 paragraph 3 (MO cooler), AD 2000, TEMA R (Gas Cooler) and C (oil coolers), and customer specifications.
