Condensation of carbon dioxide with "small" amount of gaseous hydrogen

[virk]

We are trying to find out the design criteria for a heat exchanger which condenses carbon dioxide. What makes it somewhat tricky is the fact that a yet unknown small (0-10 mass percent) amount of hydogren will be in the gas flow, too. (Evaporating ammonia will provide the refrigeration)
There are a lot of topics to be considered like temperatures, pressures, load, shell&tube or plate HE, etc. but the topic why I am posting here is the presence of hydrogen which will "deteriorate" the condensation process.
1) Is there any experience/knowledge available, how the condenser should be designed to properly fight the non-condensable-problem of hydrogen?
2) Is there any experience/knowledge available about the corrosiveness of this fluid for example against "normal" carbon steel, some stainless steel, etc.

At this stage of this project I am just trying to collect some first information.

The hydrogen will be swept to the end of the co2 condenser and will have to be vented or otherwise removed. The presence of the CO2 will slow the condensation and you will need more heat transfer area to compensate.

One additional point, the partial pressure of CO2 in the H2 leaving the condenser cannot be less than the vapor pressure of CO2 at the condenser temperature.
