Abstract
A method and system for reducing corrosion in a turbomachine. The method may include providing a process gas to a condenser, wherein the process gas contains a condensate having a pH level that is acidic. The condenser may be configured to remove at least a portion of the condensate from the process gas. Any condensate that is not removed is a remaining condensate. The method may further include increasing the pH level of the remaining condensate to above about 4 by mixing the process gas and the remaining condensate with an amount of pH modifier to form a mixture, and directing the mixture to a compressor coupled to the condenser, wherein the compressor is configured to compress the mixture.

A method for reducing corrosion in a turbomachine, comprising:
- providing a process gas to a condenser, wherein the process gas contains a condensate having a pH level that is acidic, and the condenser is configured to remove at least a portion of the condensate from the process gas, and any condensate that is not removed is a remaining condensate;
- increasing the pH level of the remaining condensate to above about 4 by mixing the process gas and the remaining condensate with an amount of pH modifier to form a mixture;
- directing the mixture to a compressor coupled to the condenser, wherein the compressor is configured to compress the mixture.
A system for reducing corrosion in a turbomachine, comprising:
- a process gas source coupled to a condenser, wherein the process gas source is configured to provide to the condenser a process gas that includes a condensate having a pH level that is acidic, and the condenser is configured to remove at least a portion of the condensate from the process gas, and any condensate that is not removed is a remaining condensate;
- a mixing mechanism coupled to the condenser and a pH modifier source, wherein the pH modifier source is configured to provide an amount of pH modifier to the mixing mechanism, the condenser is configured to provide the process gas and the remaining condensate to the mixing mechanism, and the mixing mechanism is configured to mix the process gas and the remaining condensate with the pH modifier to form a mixture, and wherein the amount of pH modifier increases the pH level of the remaining condensate to above about 4;
- and
- a compressor coupled to the mixing mechanism, wherein the compressor is configured to receive the mixture from the mixer, and compress the mixture.
A system for reducing corrosion in a turbomachine, comprising:
- a means for providing a process gas to a means for condensing, wherein the process gas contains a condensate having a pH level that is acidic, and the means for condensing is configured to remove at least a portion of the condensate from the process gas, and any condensate that is not removed is a remaining condensate;
- a means for calculating an amount of pH modifier to be mixed with the process gas and the remaining condensate to increase the pH level of the remaining condensate to above about 4;
- a means for providing the amount of pH modifier to a means for mixing, wherein the means for mixing is coupled to the means for condensing, and the means for mixing is configured to mix the amount of pH modifier, the remaining condensate, and the process gas to form a mixture;
- and
- a means for compressing coupled to the means for mixing, wherein the means for compressing is configured to compress the mixture.
