摘要：A novel method for real time process data reconciliation and a modified serial compensation technique for gross error detection are developed in order to obtain balanced and accurate process data. Based on process data reconciliation, a new matrix algorithm is utilized to analyze the dynamic production cost of final product streams and intermediate product streams. As an application, these technologies have been implemented in a large scale coal-based methanol plant successfully.
