Steady state analysis of the Tripoli West LT-HT-MED plant Original Research Article

Two units of 5000 m3/d low temperature horizontal tube multi-effect distillation (LT-HT-MED) have been recently commissioned by the General Electricity Company at Tripoli West plant to replace the old multi-stage flash (MSF) units to supply the required makeup water to the boilers. The two units are the first LT-HT-MED units that went into operation. Thermodynamic analyses for the units have been done. A computer program was written based on the mathematical models of the different plant components of the parallel feed system with thermo-vapor compression. The results show good agreement with the available data. A study on the effect of the different process variables on the plant performance have been carried out.
