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

KNOWLEDGE ENGINEERING OF A MONITORING AND CONTROL DECISION SUPPORT SYSTEM

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

Clean Technology Using Cogeneration Concepts for Simultaneous Production of Electricity, Steam, and Industrial Gases: A Route to Zero Pollution Discharge-A Case Study for Enhanced Oil Recovery in Canada

In recent years, global warming has been blamed on the so called “greenhouse effect” and has caught the attention of scientists and politicians throughout the world. There is an increasing concern surrounding the emission levels of greenhouse gases, particularly carbon dioxide (CO2). This paper is an extension of earlier work(1) to show how cogeneration concepts can be used to reduce production costs by simultaneously producing electricity, CO2 and steam for enhanced oil recovery (EOR) applications.

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
