摘要： Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed one or more active chemical species into the hot water system.

摘要： Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system undergoing a wet layup sequence to inhibit corrosion in the hot water system. The method includes separating the wet layup sequence into a plurality of phases. Each phase is either short-term or long-term and a subset of the short-term phases is optionally transitional. The method further includes defining one or more zones in the hot water system. At least one of the defined zones is selected for each phase and one or more of the selected zones include at least one ORP probe operable to measure the real-time ORP and communicate with a controller. The ORP probe(s) either intermittently or continuously measure the real-time ORP at operating temperature and pressure at one or more of the selected zones in one or more of the phases and transmit the measured real-time ORP to the controller. The real-time ORP is assessed to determine whether it conforms to an ORP setting for that phase. The invention further includes a multi-component control device for a hot water system undergoing a wet layup sequence.

摘要： A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.
