|Spanish term or phrase: pulidores de condensado|
De cara a la definición del sistema de pulidores de condensado, agradeceríamos información acerca de los contaminantes posibles procedentes de CPG Nuevo Pemex en la corriente de agua desmineralizada/condensado.
La calidad del agua desmineralizada/condensado permite eliminar el requerimiento del pulidores de condensado. Las especificaciones del agua desmineralizada/condensado de suministro son indicadas en el Capítulo 2.11 que se modifica.

ION EXCHANGE RESIN SYSTEMS
Kurita custom designs and manufactures ion exchange resin systems that remove or exchange dissolved solids from water used in the electronics, power generating, hydrocarbon, chemical and pharmaceutical industries.
• **********Condensate Polishers**********
A condensate polisher is a device used to filter water condensed from steam as part of the steam cycle, for example in a conventional or nuclear power plant. It is frequently filled with polymer resins which are used to remove or exchange ions such that the purity of the condensate is maintained at or near that of distilled water.
Condensate polishers are important in systems using the boiling and condensing of water to transport or transform thermal energy.

scrubbers / condensation scrubbers
Refers to chemical or physical items installed in the chimneys of a factory or power plant, to remove or neutralize toxic effluents that may be mixed with the steam or smoke released in order to prevent air pollution.

"This article is about the pollution control device, for other uses, see scrubber (disambiguation).
Scrubber systems are a diverse group of air pollution control devices that can be used to remove particulates and/or gases from industrial exhaust streams. Traditionally, the term "scrubber" has referred to pollution control devices that used liquid to "scrub" unwanted pollutants from a gas stream. Recently, the term is also used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to "scrub out" acid gases. Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases.
Removal and neutralization
The exhaust gases of combustion may at times contain substances considered harmful to the environment, and it is the job of the scrubber to either remove those substances from the exhaust gas stream, or to neutralize those substances so that they cannot do any harm once emitted into the environment as part of the exhaust gas stream.
A wet scrubber is used to clean air or other gases of various pollutants and dust particles. Wet scrubbing works via the contact of target compounds or particulate matter with the scrubbing solution. Solutions may simply be water (for dust) or complex solutions of reagents that specifically target certain compounds.
Removal efficiency of pollutants is improved by increasing residence time in the scrubber or by the increase of surface area of the scrubber solution by the use of a spray nozzle, packed towers or an aspirator. Wet scrubbers will often significantly increase the proportion of water in waste gases of industrial processes which can be seen in a stack plume.
A dry or semi-dry scrubbing system, unlike the wet scrubber, does not saturate with moisture the flue gas stream that is being treated. In some cases no moisture is added; while in other designs only the amount of moisture that can be evaporated in the flue gas without condensing is added. Therefore, dry scrubbers do not have a stack steam plume or wastewater handling/disposal requirements. Dry scrubbing systems are used to remove acid gases (such as SO2 and HCl) primarily from combustion sources.
There are a number of dry type scrubbing system designs. However, all consist of two main sections or devices: a device to introduce the acid gas sorbent material into the gas stream and a particulate matter control device to remove reaction products, excess sorbent material as well as any particulate matter already in the flue gas.
Dry scrubbing systems can be categorized as dry sorbent injectors (DSIs) or as spray dryer absorbers (SDAs). Spray dryer absorbers are also called semi-dry scrubbers or spray dryers."
Hope this helps. Good luck.

The descriptions of 'condensate polishers' in the excellent refs from Tana appear to define the same process as 'scrubbers'. The choice between the terms may depend upon the target country for the document.
