Simulation and Sustainability Analysis for Produced Water Thermal Desalination
Technologies

Abstract

Produced water is the largest waste stream
generated in oil and gas industries. Characterized by high salinity,
environmental concerns and the prospect of beneficial uses have driven
intensive research into produced water management. Dominant thermal
desalination technologies include Multi-stage Flash (MSF) and Multi-effect
Distillation (MED).  In this work,
several multi-stage MSF and MED processes are simulated using Aspen Plus based
on the plant data, and comparisons are made on multiple dimensions. In technological level, water recovery
and gain output ratio (GOR) are the major indicators. For economic comparison, capital and
operational costs (CAPEX & OPEX) are collected. The Waste Reduction Algorithm (WAR) is
utilized for the evaluation of their environmental impacts.
