Qualification Testing

In order to reduce the amount of carbon dioxide (CO2) greenhouse gases released into the atmosphere, significant progress has been made in developing technology to sequester CO2 from power plants and other major producers of greenhouse gas emissions. The compression of the captured carbon dioxide stream requires a sizeable amount of power, which impacts plant availability, capital expenditures and operational cost. Preliminary analysis has estimated that the CO2 compression process reduces the plant efficiency by 8% to 12% for a typical power plant. The goal of the present research is to reduce this penalty through development of novel compression and pumping processes. The research supports the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) objectives of reducing the energy requirements for carbon capture and sequestration in electrical power production. The primary objective of this study is to boost the pressure of CO2 to pipeline pressures with the minimal amount of energy required. Previous thermodynamic analysis identified optimum processes for pressure rise in both liquid and gaseous states. At elevated pressures, CO2 assumes a liquid state at moderate temperatures. This liquefaction can be achieved through commercially available refrigeration schemes. However, liquid CO2 turbopumps of the size and pressure needed for a typical power plant were not available. This paper describes the design, construction, and qualification testing of a 150 bar cryogenic turbopump. Unique characteristics of liquid CO2 will be discussed.

The Status

The greenhouse gas represented by carbon dioxide is having a negative impact on the earth's ecology. The goal of carbon neutrality is to reduce carbon emissions to zero through complete elimination or dynamic balance. Therefore, achieving the goal of carbon neutrality is conducive to restoring the earth's ecology and reducing global temperature. The main ways to achieve carbon neutrality include the use of renewable energy to replace fossil energy and carbon capture and sequestration. There is no carbon dioxide involved in the process of renewable energy production, and carbon capture and storage can directly eliminate carbon dioxide. This article reviews the ways to achieve carbon neutrality: the status quo, advantages and disadvantages of renewable energy and carbon capture and sequestration, and analyzes the current development and problems and challenges of carbon neutrality through examples.

In order to reduce the amount of carbon dioxide (CO2) released into the atmosphere, significant progress has been made into capturing and storing CO2 from power plants and other major producers of greenhouse gas emissions. The compression of the captured carbon dioxide stream requires significant amounts of power and can impact plant availability, and increase operational costs. Preliminary analysis has estimated that the CO2 compression process reduces plant efficiency by 8% to 12% for a typical power plant. This project supports the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) objective of reducing energy requirements for carbon capture and storage in electrical power production. The primary objective of this study is to boost the pressure of CO2 to pipeline pressures with the minimal amount of energy required. Previous thermodynamic analysis identified optimum processes for pressure rise in both liquid and gaseous states. Isothermal compression is well known to reduce the power requirements by minimizing the temperature of the gas entering subsequent stages. Intercooling is typically accomplished using external gas coolers and integrally geared compressors. For large scale compression, use of straight through centrifugal compressors, similar to those used in oil and gas applications including LNG production, is preferred due to the robustness of the design. However, intercooling between each stage is not feasible. The current research develops an internally cooled compressor diaphragm that removes heat internal to the compressor. Results documenting the design process are presented including 3D conjugate heat transfer CFD studies. Experimental demonstration of the design is performed on a sub scale centrifugal compressor closed loop test facility for a range of suction pressures.

Carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are expanding at lightning speed as the world increasingly embraces the need for a carbon-neutral future. As it is described on the U.S. Department of Energy (DOE) website, “CCUS is a process that captures carbon dioxide emissions from sources like coal-fired power plants and either reuses or stores it so it will not enter the atmosphere. Carbon dioxide storage in geologic formations includes oil and gas reservoirs, unmineable coal seams and deep saline reservoirs — structures that have stored crude oil, natural gas, brine and carbon dioxide over millions of years” ( https://www.energy.gov/carbon-capture-utilization-storage ). The International Energy Agency (IEA) states that “CCUS is the only group of technologies that contributes both to reducing emissions in key sectors directly and to removing CO2 to balance emissions that are challenging to avoid – a critical part of “net-zero” goals. After years of slow progress, new investment incentives and strengthened climate goals are building new momentum behind CCUS” ( https://www.iea.org/reports/ccus-in-clean-energy-transitions ).
