  Article:   HYDROGEN GAS SEPARATION SYSTEM OPTIMISATION IN HYDROTREATING PLANTS.

Authors:  DANIEL MIHAESCU, FLORIN OPREA.
 
       
         
  Abstract:  Actual study reffers to the eficiency of main four separating systems from the most new high performance hydrotreaters.The principal performance criterions are: purity of hydrogen separated, eficient heat integration, lower overall costs due to savings heat exchanger surface, separator investment and operation costs.The data are processed with two important simulation programs: PRO II 3.3, CHEMCAD 5.0.The results of the study show that the design for reactor effluent separation into gas and liquid streams has major impacts on plant operability and economics for both new and revamped units.
