Dear Sir, We have Design Spec in ASPEN PLUS V11.Like this what is there for CHEMCAD V7 ? Is it controller? Regards, CHEMSTRONG

Dear George Verghese Sir, I had a chat with with you here on compressor. Can you please share your email address as I want to show some calculations with you only. I will post those to your email address directly. Regards, CHEMSTRONG

But what should be optimum rate for current plant conditions . I think we need to evaluate first present fouling rate in compressor and aftercoolers and then see how much wash oil is required. I want to know if fouling is completely reversible ??

Dear Sir, Can you plz tell me how u did it or send me an email now ? Regards

Dear Sir, It is possible to calculated wash oil rate using simulator . But I don't know the procedure . What you have mentioned is thumb rule or best practices approach for wash oil rate !! I want to know how we can develop wash oil optimization in Hysys or any other simulation software ?

I want to know how to calculate optimum flow rate of wash oil and wash water for Cracked Gas Compressor in Ethylene Plant . How to simulate it in Hysys simulator? Please help me now. Please help me what all data is required for this now?

In Process Dynamic Simulation using hysys , we need to enter valve Cv as per datasheet..We generally use Valve sizing chart to do this.. In this Universal Gas sizig Cv is given as per line size.. But for particular stream and valve combnation, i may inlet and outlet pressures , flows in diff...
