Hi all, I'm new to the forum and of course my first act is to cry for help. I'm just wondering if anyone can help advise me on potential suppliers for a membrane separation unit for a stream containing propane, propylene, ethane, ethylene, hydrogen and nitrogen. We're aiming to recover the hydrocarbons and we'd like to be able to consider recovering the hydrogen and nitrogen streams should it prove viable. I've contacted MTR and had a positive response, but queries (repeatedly) to SIHI, BOC, UOP and Air Liquide have all been met with underwhelming response, or more accurately no response.
The location in question is Australia, so if anyone can suggest a company that might be able to provide the necessary equipment and also have the ability to reply to email, it would be greatly appreciated.

The not responding companies are so bussy that they do not bother to answer at a query that is not looking significant to them. I had the same experience with them.
Try Natco-Cynara, they tend to be very responsive.
