Dear All,

I am a chemical engineering Graduate at Texas A&M University Kingsville.

Currently working on my project " Liquefaction Of Natural Gas by C3MR process".

I got only 35% LNG.

I would appreciate your suggestions towards maximum product recovery.

I will explain about my process specifications to your fruitful replies.

Thanks a lot.

Your project is interesting to me for various reasons. I'm an Aggie -Class '60 - and I worked for El Paso LNG company during the 70's when we were the pioneer and leading LNG company in the business. I fail to understand what you mean by "I got only 35% LNG". Do you mean you've run out of feed gas? Or do you mean you've run out of refrigeration? Either way, I would have to guess that you're simulating the process and perhaps you've got problems setting up your simulation input; is that it?

Perhaps if you tell us the whole story - basic data and explanation of the problem - we might be of help on the Forum.

What I undestand from Suresh that he had a simulation and he found that the composition of methane in LNG is 35% using C3- MR cycle.

I think you have a problem with the composition of MR (C1, N2 ,C2 , C3) you have to use the right composition to get the right temperature at he exit of the main heat exchanger before going to the HP flash drum and LP flash drum and here you get LNG at -162C with almost of 85% methane liquid.

If you have another problem just give us more details as 'Art Montemayor' said.

I hope Suresh has finished the project by now, 10 months after posting this question...

Dear Art,
I really appreciate your effort towards young engineers. I saw your reply to my question and i felt sorry about not replying. I was busy preparing for my graduation(held on 5 May, 06) and job search (joined job on May 15, 06). Infact, i learned so many things from your postings. Currently working as a Flow Assurance Consultant in Houston.

Again, Thanks for your help
