ABSTRACT:
A method and apparatus for coupling a primary loop with a secondary loop for circulating processing fluids therebetween comprising in combination: a first connection for the feed line of the primary loop and a second connection for the return line of the primary loop; a third connection for the feed line of the secondary loop and a fourth connection for the return line of the secondary loop; a crossover line coupling the four connections; first valve means for controlling the flow through the secondary loop; first sensor means responsive to the temperature associated with the secondary loop to control the first valve means; second valve means in the path of flow through the crossover line; and second sensor means responsive to the flow of the process fluid across the crossover line to control the second valve means.
