This project started on 22 March 2021. The tasks include guidance and review on monitoring equipment replacement, audit of monitoring equipment setting and legal requirement of connection, audit of Zero/Span, tests on response time, audit of Opacity, Relative Accuracy Test Audit, NO2/NO convertor’s efficiency audit, CEMS parallel signal comparison, original signals extract connection and mock signal tests, orientations on relevant laws.
Standards check for pipelines emphasize on the accordance with laws. By the audit results, CEMS in public and private places would maintain its best operating condition. The feedbacks have been provided to the factories and follow-up exams have been planned to check improvements.
With regards to Zero/Span check, OP Zero is 0.00%-1.74% whereas Span is 0.06%-1.98%; FLOW Zero is 0.00%-0.59% whereas Span is 0.00%-1.75%. The monitoring equipment which is more than half specification performance is Formosa Petrochemical Corporation Mai-liao Factory III (PC01): OP Span, Formosa Petrochemical Corporation Mai-liao Factory II (P301): OP Span, Mai-liao Power (P401), OP Span, Formosa Petrochemical Corporation Mai-liao Factory III (PA01): FLOW Span, Formosa Petrochemical Corporation Mai-liao Factory II (P401): CO Zero Span, Nan-ya Plastics Mai-liao Branch (P002): NOX Span, Formosa Petrochemical Corporation Mai-liao Factory II (P501): SO2 Span, Mai-liao Power (P201): NOX Span and Formosa Petrochemical Corporation Mai-liao Factory I naphtha cracker complex (PE01): NOX Span.
The response time of the tested monitoring equipment are all in accordance with performance specification.
Audit of Opacity are all in accordance with performance specification whereas the Calibration Error which is more than half performance specification are high reflectivity neutral density filters of Nan-ya Plastics Mai-liao Branch_ P001, middle reflectivity neutral density filters of Mai-liao Power_ P201, low reflectivity neutral density filters of Formosa Taffeta CO., LTD_P002 and low reflectivity neutral density filters of Formosa Taffeta CO., LTD_P001.
About the RATA, all tests on pipelines are in accordance with the instrument performance specification of the management regulations.
Regarding NO2/NO convertors’ efficiency audit, the factories checked are Formosa Petrochemical Corporation Mai-liao Factory II pipelines 701 and 501, Formosa Petrochemical Corporation Mai-liao Factory I naphtha cracker complex pipelines PS01 and PT01, Formosa Petrochemical Corporation Mai-liao Factory III pipeline PA01. The results all accords to the specification of convertor’s performance where the efficiency is ≧90%.
36 CEMS pipelines parallel signal comparisons, 4 blind signal input tests on sequence number parallel comparison and 36 signal acquisition deviation audits have been done. The parallel comparisons results all conform to the performance specification stated in the Appendix of CEMS Management Regulation. The blind tests are all qualified. The results of signal acquisition deviation all conform to the standard of ≦1 %.
Besides, one CEMS laws orientation has been done on 1st September 2021 with 16 participants from 7 companies. One CEMS laws orientation on flare tower has been done on 1st November 2021 with 29 participants from 12 companies.
