  • Publication number: 20240125568
    Abstract: A process and system for automated online fouling prevention of vertical shell and tube gas-to-gas heat exchangers is provided. The process and system of the invention utilize the flow velocity of the gas within the tubes to facilitate cleaning of the tubes by adding, when necessary, grit to the contaminated gas flow.

  • Patent number: 9109172
    Abstract: A low-temperature gasification system comprising a horizontally oriented gasifier is provided that optimizes the extraction of gaseous molecules from carbonaceous feedstock while minimizing waste heat. The system comprises a plurality of integrated subsystems that work together to convert municipal solid waste (MSW) into electricity. The subsystems comprised by the low-temperature gasification system are: a Municipal Solid Waste Handling System; a Plastics Handling System; a Horizontally Oriented Gasifier with Lateral Transfer Units System; a Gas Reformulating System; a Heat Recycling System; a Gas Conditioning System; a Residue Conditioning System; a Gas Homogenization System and a Control System.

  • Publication number: 20130228445
    Abstract: A method and apparatus is described for the efficient conversion of carbonaceous feedstock including municipal solid waste into a product gas through gasification. More specifically, a horizontally-oriented gasifier having one or more lateral transfer system for moving material through the gasifier is provided thereby allowing for the horizontal expansion of the gasification process such that there is sequential promotion of feedstock drying, volatization and char-to-ash conversions.

  • Patent number: 8306665
    Abstract: The present invention provides a control system for the conversion of carbonaceous feedstock into a gas. In particular, the control system is designed to be configurable for use in controlling one or more processes implemented in, and/or by, a gasification system for the conversion of such feedstock into a gas, which may be used for one or more downstream applications. Gasification processes controllable by different embodiments of the disclosed control system may include in various combinations, a converter, a residue conditioner, a recuperator and/or heat exchanger system, one or more gas conditioners, a gas homogenization system and one or more downstream applications. The control system operatively controls various local, regional and/or global processes related to the overall gasification process, and thereby adjusts various control parameters thereof adapted to affect these processes for a selected result.
