Benefits of technology

The patent is about a method for removing water from an air stream using a system of packed beds. A spray head distributes liquid water to the bed surface, and the air stream passes through the bed in the opposite direction, carrying the water with it. This process removes some of the water from the air stream, resulting in a drier air stream that is more suitable for use in a gas turbine system. The technical effect is the improved efficiency and performance of gas turbine systems that use dry air.

Problems solved by technology

The water moisture deposited in this way at the filters can combine with the solid particulate matter also deposited at the filters forming a coating on the filters that interferes with the free flow of the air through the filters.
As a result, an increased pressure loss can be experienced at the filters.
In addition, the particles of water moisture can collide with one another and, as a result, drop out of the air stream.

Abstract

A moisture removal system for removing water moisture from an air stream and an associated method are provided. The moisture removal system includes one or more packed beds that include a water-entry surface at which liquid water is received and an air-entry surface that is located substantially opposite the water-entry surface and at which the air stream is received. The air stream passes through the one or more packed beds in a direction substantially counter-current to the passage of the liquid water and the liquid water and the air stream contact one another in the one or more packed beds resulting in the removal of at least a portion of the water moisture from the air stream. The moisture removal system can be located upstream of and be operably connected to the inlet of a gas turbine system to which the air stream is delivered from the moisture removal system.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to method and apparatus concerning the removal of water moisture from a gas and, in particular, to method and apparatus concerning the removal of water moisture from ambient air prior to the ambient air being applied at a gas turbine system.[0002]The removal of water moisture from gases, including the removal of finely divided water droplets suspended in air for example and referred to herein as an air / water mist, is performed in a variety of circumstances. One such circumstance, for example, concerns the operation of a gas turbine system for generating electricity in which an ambient air stream is mixed with fuel and the mixture combusted to produce gaseous products of combustion that are employed to drive a turbine that powers a rotor of an electric generator. Typically in such an operation, the ambient air that is mixed with the fuel can first be subjected to certain conditioning procedures.[0003]As an examp...
