Questions regarding the pressure and temperature of liquid chlorine exhaust gas

Thread Content

I have a question for everyone: in the processes of liquefying chlorine gas at medium temperature and pressure or at high temperature and pressure, the liquid chlorine and exhaust gases coming out of the separator have relatively high pressure and temperature! I would like to ask: when exhaust gas reaches the hydrochloric acid synthesis process and enters the chlorine buffer tank, the pressure is reduced through a control valve. This pressure reduction of the chlorine gas is equivalent to an adiabatic expansion, causing the temperature of the chlorine gas to drop rapidly. Could this lead to frosting in the buffer tank? If this portion of exhaust gas is directed to the emergency chlorine absorber, will it cause the absorbent solution to freeze? During normal operation, we plan to add a shell-and-tube heat exchanger, with the exhaust gas flowing through the tube side and the chlorine going to the liquefier flowing through the shell side – is it feasible to carry out heat exchange in this way? Has anyone done this? Please share your opinions!
