Abstract
Embodiments of the disclosure may provide an exemplary method for operating a compressor system, wherein the method may include cooling a process gas containing water vapor to a first temperature. The water vapor may form a condensate at the first temperature, and cooling the process gas may produce residual heat. At least a portion of the condensate is removed from the process gas, wherein any portion of the condensate that is not removed is a remaining condensate. The remaining condensate may be heated to a second temperature with the residual heat, wherein the remaining condensate in the process gas evaporates at the second temperature.
Claims20
A method for operating a compressor system, comprising:
- cooling a process gas containing water vapor to a first temperature, wherein the water vapor forms a condensate at the first temperature, and wherein cooling the process gas produces residual heat;
- removing at least a portion of the condensate from the process gas, wherein any portion of the condensate that is not removed is a remaining condensate;
- and
- heating the remaining condensate to a second temperature with the residual heat, wherein the remaining condensate in the process gas evaporates at the second temperature.
A moisture removal unit for a compressor system, comprising:
- a cooling unit comprising:
- a means for cooling a process gas containing water vapor to a first temperature, wherein the water vapor forms a condensate at the first temperature, and the means for cooling the process gas produces residual heat when cooling the process gas;
- and
- a means for removing at least a portion of the condensate from the process gas, wherein any condensate not removed is a remaining condensate;
- and
- a heating unit comprising a means for using the residual heat to heat the remaining condensate to a second temperature, wherein the remaining condensate in the process gas evaporates at the second temperature.
A compressor system, comprising:
- a compressor coupled to a moisture removal unit, wherein the moisture removal unit comprises:
- a cooling unit that includes:
- a means for cooling a process gas comprising water vapor to a first temperature, wherein the water vapor forms a condensate at the first temperature, and wherein the means for cooling the process gas produces residual heat when cooling the process gas, and
- a means for removing at least a portion of the condensate from the process gas, wherein any condensate not removed is a remaining condensate;
- and
- a heating unit that includes a means for heating the remaining condensate to a second temperature using the residual heat, wherein the remaining condensate evaporates at the second temperature.
A method of operating a turbomachine, comprising:
- providing, a process gas having water vapor to a moisture removal unit located at the front of the turbomachine upon starting the turbomachine, wherein the moisture removal unit includes:
- a cooling unit that includes:
- a means for cooling a process gas comprising water vapor to a first temperature, wherein the water vapor forms a condensate at the first temperature, and wherein the means for cooling the process gas produces residual heat when cooling the process gas, and
- a means for removing at least a portion of the condensate from the process gas, wherein any condensate not removed is a remaining condensate;
- and
- a heating unit, wherein the heating unit is configured to heat the process gas to a temperature at which the remaining condensate evaporates;
- providing a dry gas to the turbomachine upon shutting down the turbomachine;
- and
- providing an increasing amount of heated water to the heating unit as the turbomachine shuts down.
