  • Publication number: 20150118131
    Abstract: A system includes a solvent gas processing system having a high pressure reaction vessel configured to remove an acid gas from an untreated feed gas using a solvent in a lean solvent fluid stream. The system includes a high pressure reaction vessel is configured to output a treated clean gas and a first flow of a high pressure fluid stream via a first flow path. The system includes a turbine having a main nozzle, an auxiliary nozzle, and an outlet. The main nozzle is configured to receive a second flow of the high pressure fluid stream from the first flow path via a main flow path. The system includes an auxiliary nozzle valve disposed along an auxiliary flow path. The auxiliary nozzle valve is configured to control a third flow of the high pressure fluid stream into the auxiliary nozzle of the turbine.

  • Patent number: 5958512
    Abstract: An apparatus for forming bands of reduced coat weight of a coating on a coated web that is moving through a laminating machine includes a supply of fluid and a nozzle for directing a stream of fluid from the supply toward the web, said nozzle having a relatively small outlet aperture for directing a relatively narrow width stream of fluid toward the web compared to the width of the web to impinge on the web to reduce the coat weight over a relatively narrow width band. The bands may be formed in the machine direction of travel of the web, across the width of the web in a direction other than the machine direction and may be of various width and may be precisely or randomly placed. The reduced coat weight areas may be narrow bands or broader areas of the web.
