System and method of delivering low/pressure/low temperature fluids into high pressure/high temperature heat exchangers by means of alternate pressure equalization
An improved system is described and method of introducing low pressure fluids into a high pressure heat exchanger wherein the method includes the following steps: delivering a fluid in the liquid state into a storage tank wherein atmospheric pressure equilibrium exists; delivering the liquid from the storage tank into alternating tanks, under alternating conditions; delivering atmospheric pressure equilibrium between the storage tank and the alternating tank being filled; providing elevation differential between the storage tank and the alternating tanks such that the liquid in the storage tank can flow into the alternating tanks, under alternating conditions, when the alternating tank being filled is in opened conduit communication with the storage tank wherein one opened conduit provides atmospheric pressure equilibrium between the storage tank and the tank being filled and a second opened conduit provides liquid access to the lower tank from the storage tank; delivering high pressure vapor equilibrium to the alternating tank being emptied while, at the same time, isolating the tank from atmospheric pressure equilibrium with the storage tank.
