Ammonia and Liquid Jet Compressors

Without some data on the performance of the liquid jet compressor, the equipment downstream at 4, and the affinity characteristics of ammonia/water at 200degC/20Bar it is not possible to say.

Usually LJC do compress the mixture to an average pressure of the sum of the two inlet pressures.

This is my dilemma. If we have in the cylinder ammonia at 20 bar and 200ºC and the LJC is pulling it, and as we have lesser and lesser ammonia in the chamber it will expand, loosing pressure and consequently lower its temperature?

After 4 we have an heat exchanger to recover the heat followed by an absorver.

There should be a process description document somewhere that states how the plant should work. Critical data as to the sizing and performance of the plant should be in that document.

I do not have a plant in operation; it is an idea to go back to use cylinders, avoiding the expansion of ammonia in the cylinder and try to recover the most heat possible after work is performed.

Instead of condensing the ammonia I will absorb it and pump it to the generator.

I believe that the temperature in 2 will be always 200ºC, despite of reducing gradually the mass of the ammonia in the cylinder due to the pulling action of the LJC, and that consequently the pressure will reduce, too.

I guess I should rephrase the question, apologies about my poor English.

What formula shall I use to calculate the temperature drop inside the cylinder as the ammonia mass is reducing, due to the pulling action of the LJC?
