Abstract

Synthesizing eco-industrial parks (EIPs) through synergistically integrating industrial facilities can effectively increase economic benefits. A modular design and optimization method has been developed for synthesizing Carbon-Hydrogen-Oxygen Symbiosis Networks (CHOSYNs), considering the chemical conversion, separation, and allocation of materials within the EIP. With the practical constraints considered, the feeding of facilities, operating conditions, and flexible production structures are optimized in terms of maximizing economic revenue. The proposed method can be utilized to identify the most profitable design based on available materials and market demand, target the optimal material allocation network, and assess the feasibility and stability of the proposed design. For the studied light alkane processing cluster, the optimized system can achieve a total economic revenue of 9.73 × 108$·y−1. It can accommodate variations in operating conditions and effectively utilizes carbon and hydrogen atoms. In contrast, oxygen atoms cannot be fully utilized due to the relatively small economic benefits associated with the related products.
