Stress corrosion of partially immersed heat exchanger u-tubes
Original language description
In general, every heat exchanger is designed individually. Various aspects, such as inlet and outlet temperatures, flow rates and stream pressures are considered in design process. Pursuit of optimal reliable design, tailored to specific needs is necessary for manufacturers in order to keep up with competition. However, optimal design can be very sensitive to changes in working conditions. In this paper, stress corrosion cracking of heat exchanger u-tubes as a consequence of decreased medium level in shell space is presented. Object of the study is heat exchanger with u-tubes used in petroleum industry. There is a mixture of gas oil and hydrogen in tube space. This mixture also contains sulphur chloride and ammonia therefore corrosion aided stress cracking presents serious threat. Inlet temperature is 350 C and medium flows at the pressure of 4.27 MPa. Shell space is partially filled with cooling water pressurized to 0.88 MPa, which is turned into steam with outlet temperature up to 20
