TAILIEUCHUNG - ORGANIC CHEMICAL INDUSTRY PVC PRODUCTION BY THE SUSPENSION PROCESS

Hopke and co-workers (6), Heidam (7), Henry (8), and Barrie and Barrie (9) applied principal component analysis (PCA) to source identification, but Paatero and Tapper (10, 11) showed that PCA cannot provide a trueminimal variance solution since they are based on an incorrect weighting. In view of the limitations of PCA, a new technique, positive matrix factorization (PMF), was developed for sources identification and apportionment (12). The distinct advan- tages of PMF over PCA are that non-negative constraints are built in PMF models and PMF does not rely on the information fromthe correlationmatrix but utilizes a point- by-point least-squaresminimization scheme (12). It has been reported (13) that the source profiles produced by. | 1 Organic chemical industry PVC production by the suspension process ORGANIC CHEMICAL INDUSTRY PVC PRODUCTION BY THE SUSPENSION PROCESS SYNOPSIS SHEET Prepared in the frame work of EGTEI Synopsis-sheet-PVC suspension-30-09-05 2 Organic chemical industry PVC production by the suspension process 1.

Activity description and EGTEI contribution In order to estimate costs of NMVOC emission reduction in the organic chemical industry it was decided to split it into 4 sections and to consider an illustrative example for representing each of these sections 1 . The four sections are as follows The steam cracking process with naphtha as feedstock and ethylene and propylene as products is considered as the illustrative example taken into account for representing all the production of lower olefins ethylene propylene butanes and butadienes . Within the EC there are 50 steam crackers and these are located on 39 sites 2 . The PVC suspension process for representing a production of chemicals with sanitary impact. A process of the downstream chemistry for representing production of chemicals except the steam crackers the PVC production and the speciality chemical industry. This production can be also representative of no sanitary impact
