An ammonia synthesis process normally works as follows: Fresh feed air and hydrogen are combined with a recycle stream and the combined stream is compressed to 10 MPa. The compressed stream enters a reactor, and the entering nitrogen and hydrogen are converted into ammonia until the reaction reaches equilibrium. The reactor effluent, still at 10 MPa, enters a condenser. The liquid and vapor streams leaving the condenser are in VLE. The liquid stream, which is essentially pure ammonia, is the product. A fraction of the vapor stream leaving the condenser is purged, while the rest is recycled. There is a problem with the compressors and the pressures of the reactor and the condenser both drop to 9 MPa. The fresh feed rate and the fraction of vapor leaving the condenser that is purged each remain the same, as do the reactor and condenser temperatures. The system reaches a new steady state at 9 MPa.
