Abstract
In order to improve a maintenance of wet scrubber operation for achieving harmful and polluting gas removal efficiency at a latex glove manufacturer in Thailand, this paper presents a technique to implement the real-time monitoring and reporting alarm system for pH measurement in wet scrubbers. All pH meter outputs are applied to an existing programmable logic controller (PLC) slave located on the master-slave network for production line control. A PLC master is communicated to an operator workstation running the supervisory control and data acquisition (SCADA) software. In addition, measurement data from the SCADA software are automatically transferred to the statistical process control (SPC) software installed in a data historian server. Traditional routine manual data collection and non real-time email notification are replaced by the proposed system, which provides the continuous automatic data collection as well as the real-time display and alarm functions. The automatic and reliable email notification in real time can be also obtained. Experimental results verifying the performance of the proposed system are also included.
