Abstract:
A system of fluid sterilization of fluid of vessel is provided, such as sterilization of ballast water for a water vessel. The system incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.

Claim (Index 1):
A system for fluid sterilization for a vessel, comprising:\n an inlet for operative connection to a fluid source to provide fluid along a flow path for sterilization by the system; a heating section in fluid communication with the inlet along the flow path, the heating section is coupled to a source of heat of a vessel, the heating section heats pressurized fluid therein above prescribed thresholds for temperature, pressure, and dwell time to achieve a desired level of sterilization; a heat exchanger having a first path disposed in fluid communication between the inlet and the heating section along the flow path to preheat fluid prior to entering the heating section and having a second path positioned between the heating section and a system outlet along the flow path to cool outflow of the heating section prior to exiting the outlet, wherein the first path and the second path of the heat exchanger are configured to pass heat energy therebetween; and a plurality of valves disposed along the flow path, including a first valve positioned downstream of the inlet and upstream of the first path of the heat exchanger, a second valve positioned downstream of the first path of the heat exchanger and upstream of the heating section, and a third valve disposed along the flow path configured for proportional control of fluid flow therethrough; a plurality of sensors disposed along the flow path, including (a) a temperature sensor positioned on the flow path downstream of the heating section and upstream of the second path of the heat exchanger, and (b) a pressure sensor; and a digital controller in operative communication with the plurality of sensors to receive measurements therefrom and in operative control of at least the third valve to control flow through the system to ensure prescribed pressure and temperature profiles across prescribed ranges for pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.
