Rapid cooling of quenching of gas streams is used in a number of essential applications in the process industries. The selection and sizing of spray nozzles are the most critical decisions in the system design. GEA quench tower design consists of an open vessel in which liquid is sprayed to contact the gas. The gas enters the bottom of the tower through a side nozzle and flows upwards, counter-current to liquid that has been sprayed from the top of the tower. By the time the gas has reached the top gas outlet, it has been cooled to its adiabatic saturation temperature.

Quenching is choosing in contrast to heat exchanger because:
Quenching is different from cooling in the sense that:
Coolers belong to the technical equipment which has been successfully employed for a long time in many industries. In former applications, their main function was the heating of materials by utilizing the heat withdrawn from other materials to be cooled. The stove pipe of the good old iron stove is an example of a “classic cooler”.
