Abstract: A VOC removal system removes VOCs from an exhaust fluid of a semiconductor process. The VOC removal system measures current VOC removal parameters and passes them to an analysis model trained with a machine learning process. The analysis model predicts a future VOC removal efficiency based on the current VOC removal parameters. The analysis model generates adjustment parameters based on the current VOC removal parameters and the predicted future VOC removal efficiency. A control system adjusts the VOC removal system based on the adjustment parameters.

Abstract: A system and method for prediction of the time to service components for a fleet of portable oxygen concentrators (POCs) is disclosed. Each of the POCs include a transmitter to transmit operational data. A network interface is configured to receive operational data from the POCs. A user database contains profiles of users associated with respective POCs. An analysis engine updates the profile of a user associated with a POC in the user database based on received operational data from the POC. The analysis engine determines a similar profile in the user database to the updated profile. The analysis engine predicts a service date for the component of the POC based on the similar profile and the updated profile.

Abstract: Disclosed is an electrochemical dehumidification device based on a screen-type amphoteric ion exchange membrane electrode, comprising a core dehumidification unit which comprises, sequentially from one side to the other side, an anode air pathway, a screen-type anode electrode, an amphoteric ion exchange membrane, a screen-type cathode electrode and a cathode air pathway. The core dehumidification unit performs active dehumidification when a voltage is applied, and performs passive dehumidification when no voltage is applied. A number of the core dehumidification unit is equal to or more than one, the core dehumidification units are capable of being connected in parallel, in serial or in an overlapping mode; meanwhile, the units may also be used in combination with other dehumidification devices. The device achieves active/passive dehumidification, and is ultra-compact and flexible.

Abstract: The present disclosure provides an automatic control system for emission indexes of a desulfurization device of a thermal power unit, which comprises a first controller, a second controller and a flow controller. At the same time, the present disclosure provides an automatic control method for emission indexes of a desulfurization device of a thermal power unit. The present disclosure runs through the production and operation data of waste gas desulfurization treatment facilities, and establishes a pH optimization set value prediction model according to the data, and can realize automatic regulation and control of pH value by optimizing and controlling the pH optimization set value and the slurry flow optimization set value every moment through the dynamic model, thus solving the problem that the pH value control process is large in lag and slow in dynamics, and improving the pH value control quality.

Abstract: A gas supply system primarily designed for use with fire sprinkler systems which includes a control system which uses flow demand to automatically determine the mode of operation and switch between providing air and nitrogen. The gas supply system can operate either in standard nitrogen generation mode where nitrogen is supplied to the reservoir tank and/or sprinkler system or in a bypass mode, where sufficient pressure is only obtained by directly supplying air. The gas supply system can provide for improved safety in operation as well as the ability to operate the sprinkler system primarily when filled with nitrogen supervisory gas.
