I am a graduate student in Chemical Engineering, from Shanghai, China. I work on techno-economic studies of the coal biomass to liquids (CBTL) plant with CO2 capture and storage (CCS). The CBTL plant is one of the potential solutions for the production of alternative transportation fuel. In this project, plant-wide models of the indirect, direct and hybrid CBTL plants with CCS are developed in Aspen Plus, while the techno-economic analysis is performed using Aspen Process Economic Analyzer.

Techno-Economic Studies of Coal-Biomass to Liquids (CBTL) Plants with CO2 Capture and Storage (CCS)
In this project, indirect, direct, and hybrid liquefaction routes are investigated for production of transportation fuels from coal and biomass. Addition of biomass and application of carbon capture and storage (CCS) technologies are studied for reducing the carbon footprint. Due to easy availability and low cost of the shale gas in the U.S., utilization of shale gas in the direct and hybrid routes was investigated for producing hydrogen at a lower cost with reduced CO2 emission in comparison to the traditional coal gasification route. Because the quality of the syncrude produced from ICL and DCL technologies vary widely, the hybrid coal liquefaction technology, a synergistic combination of ICL and DCL technologies, is investigated for reducing the penalty of downstream syncrude upgrading unit through optimal blending. Significant amount of CO2 that is generated in the hydrogen production unit(s) is captured to satisfy the target extent of CO2 capture. Different CCS technologies are considered and optimized for the indirect, direct and hybrid CBTL plant depending on the sources of CO2 containing stream and corresponding CO2 partial pressure. High fidelity process models are developed for indirect, direct, and hybrid CBTL plants with CCS. These models are leveraged to perform comprehensive techno-economic studies. Contributions of this project are as follows: (1) development of the systems-level and equipment-level process models and rigorous economic models in Aspen Plus, Aspen Custom Modeler, Aspen Exchanger Design and Rating, and Aspen Process Economic Analyzer platforms, (2) sensitivity studies to analyze the impact of key design parameters (i.e. biomass/coal ratio, operating conditions of key equipment, extent of CCS, CCS technologies, blending ratio of the syncrude and products in the hybrid route) and investment parameters (i.e. price of coal and biomass, project life, plant contingency and plant capacity) on key efficiency measures, such as thermal and carbon efficiency, as well as economic measures, such as the net present value, internal rate of return and break-even oil price, (3) comparisons and analyses of trade-offs of indirect, direct, and hybrid CBTL technologies.
