A modular gas processing system built with various gas processing modules and cubes improve transportability and customization. Individual gas processing modules and cubes can be included or removed in multiple combinations for customization because each module has a common interconnection point for connecting to any other gas processing module and cube.

A method, an IoT system, and a storage medium for dehumidification monitoring of an ancillary facility in a smart gas pipeline network are provided. The method comprises: obtaining humidity monitoring data collected by a gas equipment object platform, wherein the gas equipment object platform includes a humidity monitoring component and a dehumidification component; the humidity monitoring component is configured to monitor the humidity monitoring data, the dehumidification component is configured to dehumidify a pipeline vault; determining a dehumidification parameter based on the humidity monitoring data and a downstream feature of a gas pipeline, wherein the dehumidification parameter includes a self-cleaning cycle of the dehumidification component, and the downstream feature includes a gas usage frequency of downstream gas; and sending the dehumidification parameter to the dehumidification component, and controlling the dehumidification component to perform self-cleaning based on the dehumidification parameter.
