Fuel Gas Network Synthesis Using Block Superstructure

Heat exchanger network synthesis with multiple utilities using a generalized stagewise superstructure with cross flows

Most of the existing simultaneous approaches for heat exchanger network synthesis assume that only one type of hot/cold utility is available to adjust the final temperatures. In this work, we propose a simultaneous mixed-integer nonlinear programming formulation based on a more generalized stagewise superstructure. We allow utilities to adjust the temperature of process streams in each stage. W...

Liquid Fuel Production from Synthesis Gas via Fermentation Process in a Continuous Tank Bioreactor (CSTBR) Using Clostridium ljungdahlii

The potential bioconversion of synthesis gas (syngas) to fuels and chemicals by microbial cell has attracted considerable attention in past decade. The feasibility of enhancing syngas bioconversion to ethanol and acetate using Clostridium ljungdahlii in a continuous tank bioreactor (CSTBR), kinetics and mass transfer coefficient of carbon monoxide (CO) utilization were evaluated. Two different ...

A Superstructure Based Optimisation Framework for Batch Water Network Synthesis with Multiple Wastewater Treatment Models

The existence of numerous water treatment/regeneration technologies capable of increasing the reuse opportunities for water–using network of batch processes calls for a systematic methodology to choose between them. Hence, this article aims to propose a new framework for the synthesis of total water network in batch plants when varieties of treatment units are available. First, a state space su...
