Acceptance criteria for soda separator?

It is actually very difficult to measure the water content in steam; so how can we assess the effectiveness of this steam-water separator?

What is the purpose of using clean steam, obtained by removing tiny liquid droplets with a steam separator in the steam pipeline? Prepare the turbine inlet steam?

Soda separation naturally involves removing the water droplets and foam carried by the steam. Depending on the use of steam, the degree of dehydration varies, and there are also several different types of detection methods. I was asking about the uses of steam, not the function of the demister.

What was said upstairs is correct; the installation of steam-water separators in steam pipes is done for specific reasons. For example, if the steam pipes are long, the accumulation of large amounts of condensate can lead to water hammer. It may also be done to improve heat exchange efficiency, or because the system cannot handle large amounts of condensate. This separation requires no high standards and is easy to achieve; it just needs to be installed, with no strict acceptance criteria required.

What was said upstairs is correct – steam pipes are equipped with steam-water separators, and of course, this varies depending on the purpose and requirements of the steam. For example, some steam pipes are quite long, and the accumulation of condensate can cause water hammer; in other cases, steam users aim to improve heat exchange efficiency, or it may not be allowed for large amounts of liquid to enter. The former has low requirements and is easy to achieve; it’s sufficient to simply install it, with no need for any acceptance standards, while the latter is different.

It’s just necessary to establish construction acceptance standards for the completion of a project

Steam is used for the desorption of activated carbon adsorbent materials

For the gas used in the analysis of activated carbon adsorption materials, high-temperature non-condensable gas should be employed. Using steam, especially saturated steam, is highly inappropriate. And even when clean, saturated steam without any droplets or foam comes into contact with activated carbon, it will rapidly liquefy due to the surface physicochemical effects. If it is superheated steam, there are no liquid droplets or foam, so the steam-water separator is unnecessary. The separation efficiency of the soda separator is no longer important. Even clean, saturated steam without any droplets or foam in contact with the activated carbon causes it to liquefy rapidly, resulting in the activated carbon becoming quickly saturated with liquid phase. The consequences are predictable. The main issue is the lack of a good understanding of surface chemistry in the process design.

Thank you! ! So, according to your understanding, what aspects of steam quality need to be considered when using gas for activated carbon purification? Won’t steam entraining water affect the resolution? Our equipment supplier has been telling us to ensure good steam quality
