Embodiment Construction

[0016] A method for developing an optimized corrosion protection system for air-cooled condensers is disclosed. The generated model was used to optimize the treatment and supply of corrosion inhibitors to the vapor system of an air-cooled condenser in order to inhibit and minimize corrosion. In general, a corrosion inhibitor is any substance that effectively reduces the rate of corrosion when added to the environment. Inhibitors can be identified with respect to their function (eg, removal of corrosive species, passivation, precipitation, or adsorption). The solution optimizes, for example, the chemistry of corrosion protection feed, timing, feed rate and feed point.

[0017] In an embodiment, a computer-implemented method for establishing a corrosion protection system for an air-cooled condenser utilizes one or more processors and associated memory storing one or more programs executed, the one or more programs including instructions for: receiving data associated with at l...

Abstract

A method for establishing a corrosion protection system for an air cooled condenser is disclosed. The method includes receiving data associated with the physical properties and chemical process conditions of the air cooled condenser, utilizing a chemical process modeling component to simulate conditions of the air cooled condenser, and identifying an optimized corrosion protection system based onan evaluation of iteratively altered input variables.

Description

technical field [0001] The present invention relates to a method for inhibiting corrosion caused by process conditions in air-cooled condensers. Background technique [0002] In steam generating systems such as power plants, air-cooled condensers are used to convert steam from a gas to a liquid after the steam has passed through a steam turbine. One widely used dry cooling system is direct dry cooling. In this dry cooling method, water vapor expands in a steam turbine, exits from the turbine through a relatively large diameter steam tube, and then passes through an upper distribution chamber where the water vapor enters the steam-air heat exchange condensers, such as air-cooled condensers. [0003] Air cooled condensers may include steam inlet piping, condenser tubes and condensate outlet piping. Turbine exhaust steam enters the condenser through the steam inlet pipe and flows through the condenser tubes. The steam condenses inside the condenser tubes, which are cooled e...
