  • COMMUNICATION SYSTEM, MONITORING SYSTEM AND RELATED METHODS
    Publication number: 20230125347
    Abstract: Disclosed herein are a communication system, a monitoring system for in-situ monitoring of a substance used in a gas scrubbing process, and related methods. The monitoring system can be used to monitor the at least one substance and provide treatment data for treating the at least one substance. The communication system includes a cloud server, a first server, a second server, and a third server. The first and second servers respectively include first and second communication interfaces configured to provide spectral information to the cloud server. The cloud server is configured to generate a calibration model including at least one parameter; apply the calibration model to the spectral information provided by the second server, whereby at least one value for the at least one parameter is extracted; and provide the at least one value for the at least one parameter to the first server via the first communication interface.

  • Preparing expandable styrene polymers
    Patent number: 8455559
    Abstract: The invention provides a process for preparing expandable styrene polymers which comprises the steps of: (a) adding an aqueous phase comprising a suspension stabilizer and an organic phase comprising styrene and an initiator to a reactor, (b) commencing the addition of a blowing agent at a styrene conversion in the range from 40 to 70% and adding the blowing agent over a period ranging from 30 to 60 minutes, (c) adding a stabilizer to stabilize the bead size distribution of the expandable styrene polymer at a styrene conversion in the range from 65 to 99%.
