Abstract: A system and method for capturing and separating carbon dioxide from mixed gas streams. The gas stream is processed in a structure including a compression module comprising a plurality of compressors, intercoolers and inter-stage condensate separators. The flow path from the compression module includes a plurality of flow separators, gas stream splitters, heat exchangers and at least a first mixer and a first expander. The gas stream is sequentially compressed and cooled to form process condensate and separate it from the compressed gas stream. The gas stream is further dried and cooled to liquefy carbon dioxide and separate it from the non-condensable portion. Selective expansion of liquid carbon dioxide streams provides cooling for the system, and further energy efficiency is achieved by selective recycling of portions of gas streams, allowing for compact equipment and economical operation, while providing for high purity product streams of carbon dioxide.

Abstract: An electrostatic precipitator and a method of removal of particulates from gaseous flows. A plurality of screens, secured in sets within a central chamber in a housing, include at least one set of electrically chargeable first screens and at least one set of electrically grounded second screens. For each set of chargeable screens, all the screens of the set are provided with an identical electrical charge, either positive or negative, and the set is provided with a plurality of spikes directed at the oncoming gaseous flow. At least one screen cleaning unit selectively acts on the screens of each set. The precipitator can include a plurality of central chambers in a single housing or separate housings, and the chambers can be selectively activated or deactivated. The precipitator provides improved particulate removal from gaseous flows, including hot flows having temperatures up to at least 1200° C.
