Газ проходит через реактор, в котором разлагается по крайней мере частично до углеродной составной части и водородной составной части. Углеродная составная часть удаляется до требуемого уровня. Различные оставшиеся составные части вместе с водородной составной частью поступают на процесс сжигания, в то время как углеродная составная часть удаляется из процесса для отдельного использования.

Cured in place liner system and installation methods

A cured in place liner system and associated connections and methods are disclosed. The cured in place pipe system forms a completely rehabilitated, stand-alone, fluid-tight flow path between upstream and downstream portions of an existing pipe system. The rehabilitated flow path is stand-alone in that the liner system does not rely on structure of the portion of the pipe system through which the liner system is installed to define the fluid-tight flow path. The flow path between upstream and downstream portions of the liner system is defined by and made fluid-tight solely by components of the rehabilitation system such as cured in place liners and couplers. The portion of the pipe system through which the rehabilitation system is installed merely provides a path (e.g., through the ground) through which the cured in place liner system can be inserted. After the cured in place liner system is installed, the liner system forms a fluid-tight flow path between an upstream portion of the pipe system and a downstream portion of the pipe system. Various types of connections may be used. In addition, various types of methods may be used in forming the connections, such as using a mold to cure connecting sections of the cured in place liners in desired configurations (e.g., having a generally circular outer profile) for forming connections with the liners.
