An embodiment of the present invention provides a water wash system that may mix a cleaning fluid with at least one chemical agent to form a cleaning solution. The cleaning solution may reduce the corrosives on components of a compressor. The cleaning solution may be an mildly acidic solution to reduce corrosion of a caustic nature. Alternatively, the cleaning solution may be a mildly basic solution to reduce corrosion of an acidic nature.

An embodiment of the present invention provides a water wash system that may mix a cleaning fluid with at least one chemical agent to form a cleaning solution. The cleaning solution may reduce the corrosives on components of a compressor. The cleaning solution may be a mildly acidic solution to reduce corrosion of a caustic nature.

Systems and methods for fault prediction are described to reduce equipment failure by effectively monitoring equipment, removing anomalous data, and reducing false alarms. Such systems and methods can be used to receive monitoring data, extract information from the data, and combine extracted information for establishing prediction models. Additionally, fault probabilities may be quantified and faults may be predicted based on the probabilities.

Fault prediction of monitored assets

A method and system for operating a facility having a plurality of equipment combinations wherein each equipment combination is operating interactively with at least one of another of the plurality of equipment combination is provided. The method includes receiving, in real-time, for each of the plurality of equipment combinations, a plurality of measured process parameters, determining at least one derived quantity from the plurality of measured process parameters, and recommending a change to an equipment operation based on the measured process parameters and the derived quantities.

Systems for monitoring machinery

An embodiment of the present invention measures a sample of the airstream, in real time, for a corrosive, before the airstream enters the compressor. An embodiment of the present invention may then initiate an on-line water wash system to reduce the level of the at least one corrosive on the compressor. An embodiment of the present invention also provides an on-line water wash system that may mix a cleaning fluid with at least one chemical agent to form a cleaning solution. The cleaning solution reduces the level of corrosives on components of a turbomachine compressor. The cleaning solution may be an acidic solution to reduce corrosion of a caustic nature. Alternatively, the cleaning solution may be a basic solution to reduce corrosion of an acidic nature.

Inlet air conditioning system for a turbomachine

A method of operating a turbine, the method including the steps of: 1) gathering measured creep data for a blade while the turbine operates at different operating temperatures, the measured creep data comprising at least a measured creep rate for the blade (wherein the different operating temperatures include at least a first operating temperature and a second operating temperature); and 2) given the measured creep data for the blade while the turbine operated at the first operating temperature and the measured creep data for the blade while the turbine operated at the second operating temperature, determining whether operating the turbine at the first operating temperature or the second operating temperature is more economically efficient.

Determining optimal turbine operating temperature based on creep rate data and predicted revenue data

A method for determining the radial deformation of a blade in a turbine that includes: 1) taking an initial measurement of the blade with one or more proximity sensors disposed around the circumference of a stage of blades; 2) after the initial measurement, taking a second measurement of the blade with the one or more proximity sensors; 3) making a determination of the radial deformation of the blade by comparing the initial measurement to the second measurement. The initial measurement and the second measurement may be taken while the turbine is operating.

Method for monitoring driven machinery

A method for controlling a rotational speed of a rotor having at least one rotor blade, a rotor shaft, and an electrical generator coupled thereto. The method includes controlling a torque of the rotor shaft by controlling a torque of the electrical generator, alternating between changing an angle of pitch of the at least one rotor blade and maintaining the angle of pitch of the at least one rotor blade substantially constant, and maintaining a substantially constant rotational speed of the rotor during variable wind speeds above a predetermined rated wind speed.
