I have multi stage 3 stage Steam Jet Ejector System for Vacuum Tower. I want to know if first stage inlet temp is around 95 deg C then what should be first stage condenser outlet temp and similarly other stages outlet temps .. Please help me. Also tell me is there any ratio of steam to vapor to be maintained for efficient ejector operation..

Just Google with keyword as "steam jet ejector" and you will find plenty of information in the form of articles and guides etc. Understand the subject before you post a question as your question is not clear and seems quite generic in nature to which answering is little difficult.

You should cool down as much as you can to condense steam and reduce the load to the higher pressure stages.

Can be spray condensing or indirect condensing.

Heat exchanger area, pressure drop and steam cost economics will dictate the temperature approach and size of the heat exchanging equipment.

Get ejector load curves from the supplier.
