The Project’s Solution
For the implementation of the project’s objective, it was decided to split the process of the facility into two stages:
Stage 1: To cool the air by means of the “heat recovery” method with the help of cold air that flows out of the cold-grade heat exchanger.
Stage 2: The cold-grade heat exchanger - a heat exchanger that cools the air down by means of the glycol brine, to an even lower temperature.
This method ensures the purpose of the process, to dry out the air on the one hand, and conserving energy for first-degree cooling and of reheating, on the other. With strenuous efforts contemplating about the many design alternatives and in different operational regimes, the choice for the welded heat exchangers, which were at the forefront of this new technological capability, was formulated.
Another requirement of the process was a high periodicity of the load. To address this issue, we have introduced improvements to the internal structure of the heat exchangers. We have commissioned in late 2013 these heat exchangers from TRANTER, which Krashin-Shalev represents in Israel (since 1985).
