Disclosed herein are systems and methods for reducing power plant CO2 emissions. In one embodiment, a method for reducing emissions in a combustion stream, comprises: combusting a gaseous stream to produce an exhaust stream comprising carbon dioxide, and separating CO2 from the exhaust stream by passing CO2 through a membrane to produce a CO2 product stream and a CO2 lean exhaust stream.

A power generation system includes first and second turbines. The first turbine including a low-pressure compressor (14) and a high-pressure compressor (16). A combustion chamber (22) combusts compressed oxidant and a fuel stream to generate a hot flue gas (31). The first turbine further includes a high-pressure expander (20) for receiving the flue gas and generating a CO2 rich exhaust gas. A low-pressure expander (22) generates a first final exhaust (52) and electrical energy. A CO2 separation system receives exhaust gas (38) and provides a CO2 lean gas fed to low-pressure expander (22). The second turbine including a compressor section (64) configured to discharge a recycle stream (71) from a high pressure compressor (70) to a second combustion chamber (72) and supply a split stream (84) from a low-pressure compressor (68) to high pressure compressor (16) of the first turbine.

摘要:
Power plants and process for lowering CO2 emissions generally includes extracting a portion of the recirculated CO2-rich flue gas mid-way through the compression pathway of a gas turbine and removing the CO2 in a separation unit. The remaining portion of the CO2 rich flue gas (i.e., the portion of the recirculated flue gas that was not fed to the separation unit) is mixed with fresh air coming from an additional compressor-expander and then fed back to the compression pathway. As a result, flue gas recirculation increases the CO2 concentration within the working fluid, leading to an additional increase in CO2 partial pressure. As the concentration and partial pressure of CO2 is increased, a lower energy penalty is observed to remove the CO2. Moreover, a reduced volume is fed to the CO2 separation unit during operation. Consequently, the size of the separation equipment can be reduced as well as the energy required for the separation process.

A mailer for disks. The mailer has first and second pockets for receiving disks, each pocket formed of front and back rectangular panel members joined at at least one pair of corresponding edges and unconnected on at least one pair of corresponding edges. The pockets are foldably attached by a spine at an edge of each of said pockets. There is a sealing member for adhering the first pocket to the second pocket to maintain the mailer in a closed conformation. At any pocket edge not retaining the received disk by the joined edges, the spine, or the sealing member, the disk is retained in the pocket by retaining means.

In one aspect, there is provided a handheld vision tester comprising a display, cursor control, interface port, and camera. The display delivers a series of images making up vision tests to a user who interacts with the vision tests by using the display and cursor control of the handheld vision tester. The camera verifies the user is taking the vision tests. The results of the vision tests are stored in the handheld communication device. The interface port allows for communication of the stored results of the vision tests with external devices. In another aspect, there is provided a calibration system for the handheld vision tester. The calibration system includes a stand to hold the handheld vision tester and a reflective surface substantially parallel to a display of the handheld vision tester.

A system for power generation includes a boiler configured to receive heat from an external source and a liquid stream and to generate a vapor stream. The liquid stream comprises a mixture of at least two liquids. The system also includes an expander configured to receive the vapor stream and to generate power and an expanded stream. A condenser is configured to receive the expanded stream and to generate the liquid stream. The system further includes a supply system coupled to the boiler or the condenser and configured to control relative concentration of the two liquids in the liquid stream.
