Abstract: A guide for cutting a dowel pin of a rotor assembly is provided. The guide includes a catch basin, including a first catch basin portion and a second catch basin portion, and a shim. The first catch basin portion and the second catch basin portion form a cutting tool receiver. The shim extends from a first edge having a cross-section that is complementary to a surface of the rotor assembly. The first catch basin portion and the second catch basin portion form a receptacle that accommodates and retains portions of a dowel pin during and after removal of the dowel pin from the rotor assembly. The cutting tool receiver is defined by a receiver edge configured to guide a cutting surface of a cutting tool through a cross-section of a dowel pin.

Abstract: Systems and methods for the separation and capture of carbon dioxide from water are generally described. In some embodiments, a vapor stream containing carbon dioxide and water is separated using a cascade of at least two flash drums. Additional flash steps may be incorporated to remove atmospheric gases, such as nitrogen and argon, from the feed. Carbon dioxide may be condensed and pressurized at purities suitable for pipeline transport and eventual storage in geological formations. In addition, water may be recovered at high purity. In some embodiments, fuel cells may be used in combination with fuel reforming or gasification to produce syngas. Certain aspects of the invention involve innovations related to the combined reforming and fuel cell process, that, in certain embodiments, do not depend upon water and carbon dioxide separation.
