Hi chemical expert,

I'm trying to get the hydrocarbons' phase diagram. This is to enhance my understanding on when the ethane for example will be transformed into gas phase at given pressure and temperature.

You guys out there must be expert and read a lot as compared with the beginner like me. Really appreciate if somebody could copy me to the suitable link for the information.

cheers Pal.

Ishams:

Reading doesn't make an "expert". First-hand results and knowledge do.

To obtain a phase diagram for ethane - such as a Mollier diagram or a "T-S" diagram, you can use one of two sources that I know of:

1) The GPSA Engineering Databook gives you detailed diagrams of the major hydrocarbon compounds - especially ethane;

2) The NIST database (free on the Internet) will give you a tabulated listing of all the properties of saturated Ethane. To find out the URL for the NIST database, use the SEARCH feature on our Forums and you will find it in one of my threads.

I hope this helps you get what you want.

Hi again Jedi,

It's me again with a new question to you. What will happen to CO2, H2S named offgas for AGRU system prior to emit to atmosphere. Specifically, if could clarify the chemical reaction for typical incinerator would be useful for me.

Thanks to you

If you have a new question, start a new thread topic.

The answer to your question is that most of the time it will be routed to a Sulfur Recovery Unit, sometimes to acid gas injection. There are other processes available but these are the major ones.

[JoeWong]

As indicated by Joerd, route to Sulfur Recovery Unit (SRU) for Sulphur production while route acid gas injection (AGI) is mainly for well disposal.

Of course, another common disposal is route to (Regenerative) Thermal Oxidizer (RTO) for component breaking and disposal-off in atmosphere.
