1 The Facility
National Petrochemical Company (NPC) is intending to build a petrochemical plant in Ilam, located in west of Iran. The Ilam Petrochemical Complex (ILPC) is consisting of the following plants:
- Olefin plant (450,000 ton/y)
- HDPE plant (300,000 ton/y)
- Power (100 Mwh) & steam generation plants (120 ton/h)
2 Feed Specification
This project has 4 different inlet feeds as following table:

3 General overview and process description
After discussion and calculation of High Operation Cost mainly from chemical consumption, that was decided to consider ZLD Package for treatment of all stream in Ilam complex.
The ZLD system is consists of:
*Degasser system: A degassing system consisting of a degassing column, flash tank, and set of preheaters has been provided to separately degas the spent caustic stream before mixing it with the wastewater.
*Four Effect Forced Circulation Evaporation:
Heating of wastewater by pre-heaters and perform the process of evaporation and separation in the evaporator.
*Pusher Centrifuge & Dryer System
for separating the salt and crystal-clear water from the wastewater feed.
Schematic of process is shown as below:
