摘要： A polymer finishing process including: recovering polymer powder from a polymerization reactor; feeding the polymer powder to an inlet of a mass flow screw conveyor and one or more mass measuring devices for determining a mass of polymer powder within at least a portion of the mass flow screw conveyor; measuring at least one of a mass of the polymer powder in the screw conveyor and a combined mass of the screw conveyor and the polymer powder within the screw conveyor with the one or more mass measuring devices; and determining a mass flowrate of polymer powder through the mass flow screw conveyor based on the at least one of the measured mass of the polymer powder in the mass flow screw conveyor and the measured combined mass. A method of controlling a polymerization process using a mass flow screw conveyor is also disclosed.

摘要： PURPOSE: To maintain measuring accuracy and to reduce costs, by performing the time division of the measured signals from a plurality of measuring parts, sending the signals through a single channel, separating the signals after A/D conversion, and sending the signals to average value computing parts correspondind to the measuring parts.
CONSTITUTION: The measured analog signals from measuring parts 1 are sequentially supplied to an A/D converter 2 through a first time division switching part 4 in a circulating mode. The signals are converted into the measured digital signals. The measured digital signals are separated through a second time division switching part 5. The signals are supplied to average value computing parts 3 corresponding to the measuring parts 3. A time division supplying circuit 6 supplies the time division switching signal to the switching parts 4 and 5. By using only one A/D converter 2, the measuring accuracy, which is similar to the accuracy obtained by providing a respective A/D converter to each measuring part 1, can be obtained. The cost of the conveying and measuring apparatus can be reduced.
