Calcium chloride solution is an important industrial refrigeration refrigerant and a flocculant in sodium alginate industry and soybean industry. Calcium chloride is generally produced with multi-continuous reactors, and thus the process of the scaling problem and its solution are of great significance. In the small scale , by the pulse method, we obtain the residence time distribution, taking advantage of a computer software，and thereby obtain the average residence time of 166.4、292.9、443.2min, variance is 39151.2、43975.7、62038.1, N = 0.7、2.0、3.2， in the three tank reactors ,while the average residence time of 24.9min, variance 128.3 in the tube reactor. In the middle scale test, we take potassium chloride as a tracer and measure the conductance of the solution to determine indirectly the residence time of the platform designed for production of liquid calcium chloride, thereby obtain the average residence time of 100min, the average variance of 1000 , N = 7. of the platform.
