Evaluation of the CO2 capture performance of the University of Regina CO2 technology development plant and the boundary dam CO2 demonstration plant

Publisher Summary The aim of this chapter is to review the CO2 capture performance from recent test results obtained from two major testing facilities of the international test centre for CO2 capture (ITC)— the boundary dam demonstration plant and the university of Regina (UR) technology development pilot plant. The facility has been used to evaluate the performance and reliability of absorption-based technologies as well as to obtain process design information under a wide range of operating conditions. The performance is presented in terms of CO2 capture efficiency, mass-transfer performance, and minimization of heat duty for solvent regeneration. The effects of reboiler heat duty on capture efficiency and operating parameters such as rich- and lean-CO2 loadings are also evaluated. Also, the energy efficiency improvement for the monoethanolamine (MEA) scrubbing technology resulting from using alternative operating conditions is discussed. In addition, operational challenges such as solvent stability are presented and discussed as a function of both the operating conditions and cost effective operating strategy. A comparison is also made of all the results obtained from the UR technology development pilot plant with those obtained from the boundary dam demonstration plant.

New feasibility study of carbon dioxide production from coal-fired power plants for enhanced oil recovery: A Canadian perspective

The concept of capturing carbon dioxide from coal-fired power plants and utilizing it as a flooding agent for enhanced oil recovery (EOR) processes is currently drawing much interest from oil, utility and coal companies in Western Canada. Implementation of such a scheme would provide two important benefits : (i) the captured CO 2 could be marketed as a flooding agent which would generate revenues, and (ii) CO 2 emissions to the atmosphere would be reduced. Since CO 2 emissions are considered to be the main contributor to the possible serious environmental problem of global warming, the proposed scheme could become an important instrument to reduce such emissions at minimal incremental cost to the environment. This paper demonstrates how cogeneration concepts, together with process optimization strategies, help to reduce the CO 2 production cost by utilizing low-pressure steam and waste heat from various sections of the power generation process. Based on these concepts and strategies, results from this study show that the recovery cost of CO 2 from a coal-fired power plant can range between

The International Test Centre for Carbon Dioxide Capture (ITC)

A large amount of carbon dioxide (CO 2 ) is being produced from fossil fuel fired power plants and discharged into the atmosphere annually. As a result, the discharged CO 2 is now suspected to have caused the greenhouse effect and global warming problem. To overcome this CO 2 emission problem, there is great interest, especially in Canada, to capture carbon dioxide and utilize it as a flooding agent for the enhanced oil recovery (EOR) process. In the past few years, a number of feasibility studies and a few testing pilot projects on CO 2 extraction from power plants were performed. However, their results have showed that even though it is technically feasible to extract CO 2 from power plants, its cost is high for the EOR application in the current crude petroleum market. A major reason for the high cost is that the CO 2 extracting process requires a substantial amount of energy. This paper demonstrates how cogeneration concepts together with optimization design strategies would help to reduce the CO 2 production cost by utilizing low-pressure steams and waste-heats from various sections of the power generation processes for extracting CO 2 . The economics and technical feasibilities of these concepts are described and the practical implications given Western Canadas resources for EOR applications are discussed

Pilot Plant Studies of the CO2 Capture Performance of Aqueous MEA and Mixed MEA/MDEA Solvents at the University of Regina CO2 Capture Technology Development Plant and the Boundary Dam CO2 Capture Demonstration Plant

This paper presents the development process of a decision support system for pre-filtering and analysis of data for the carbon dioxide (CO2) capture process. Chemical absorption is becoming one of the dominant CO2 capture technologies because of its efficiency and low cost. Since the chemical absorption process consists of dozens of components, it generates more than a hundred different types of data. Monitoring the vast amount of data can be complex, and data filtering and analysis processes are desirable. Specifically, invalid data captured as the equipment is started and shut down need to be filtered, and the filtered data need to be analyzed for different purposes. The data analysis support system not only filters out invalid data using different expert rules, but can also modify or reuse filtering settings, and export the filtered data to various file formats for further analysis. During development of the decision support system, knowledge acquisition was emphasized. The system was designed based on the model-view-control (MVC) design pattern. Source code management (SCM) software and strategy were applied to allow multiple developers to work together. Embedded database technology, Java event delivery techniques and extensible Markup Language (XML) were also included in development of the system.

Corrosion in MEA units for CO2 capture: Pilot plant studies

In order to sustain the current production capacity of conventional oil in Western Canada, enhanced oil recovery (EOR) technologies must be increasingly applied. Among these, CO2 flooding is a highly attractive alternative. A large amount of CO2 is being produced by coal-fired power plants in this region. The CO2 is currently discharged into the atmosphere and could be a major contributor to the greenhouse effect, which may lead to global warming. Thus, the concept of capturing CO2 and utilizing it as a flooding agent in EOR processes is currently generating much interest among oil, utility and coal companies. We demonstrate how cogeneration concepts, together with process-optimization strategies, help to reduce the CO2-production cost by utilizing low-pressure steam and waste heat from various sections of the power-generation process. Based on these concepts and strategies, results from this study show that the recovery cost of CO2 from a coal-fired power plant may range between
