求助翻译下面内容，万分感激！ Comalco Alumina Refinery Located Gladstone,QLD Comalco-100% Rio Tinto Owned Stage One Announced October 2001-1.4Million tpa Came on-line September 2004 Rapidly approaching nameplate production rate Planned for 3 Stages-4.2 mtpa Australia’s Newest Alumina Refinery Presenters -Terry Snow : Process Control Superintendent -Jason Freyling : Process Control Engineer Presentation Overview Simulator-Cost Benefit -System Overview -Strategy for sustaining a simulator post commissioning -Cost/Benefit Analysis for 2005 -Application Case Study-Digestion Feed Pump Jump-Over -Application Case Study-7# Digestion Feed Pump -Lessons learnt Simulator – System Overview Developed by Honeywell as part of the CAR 1 construction project Estimated cost to commissioned (internal and external) ~A$4.5M Accepted by Management that Simulator paid for itself -For plant commissioning/start-up period -This is not relevant today (apart from credibility) Challenge-sustaining simulator post commissioning – can it be justified, how to do it System Benefits>System Sustaining Costs Training benefit diminishes over time* Support Costs need to diminish over time CAR Simulator Asset Intent – for lifetime of refinery Simulator Sustaining Strategy SWOT analysis – clearly identify costs and benefits – Formal annual C/B Maximize Benefits (not easily related to $ - really usage) -Number of operators trained -Number of control app’s tested (fast response to request) -Number of Procedures developed -Extend usage base (QA, Process Engineers) Minimize Costs (quantitative $) -Reduce effort required to resynch DCS (automation/tools) -Provide adequate simulator fidelity (qualitative assessment) -Provide adequate simulator scope (minimal effort for duplicated plant) -Labour substitution (right hourly rate for parts for parts of work) -Incremental Resynch + Full Resynch (at least 1 full per year per model) Console Training based Simulator System Simulator Training System Simulator Cost/Benefit Simulator Cost/Benefit – 2005 Costs (system, not training) - Internal Labour (1185 hrs) Resynch Trainer Support Documentation, Tool development - External Labour (305 hrs) Resynch Cap Project Tech Assist Train the trainer - License (HSE&SP) - Travel and Accom Total Cost ~$160,000 - 7 Full Resynchs - Multiple partial resynch’s - Resynch effort reduced from 120 hr to 20 hrs - Significant reduction in use of external labour Benefits (usage) - 21 operators trained 4 standard Boiler Tickets 2 Advanced Boiler Tickers - 4 Trainers trained - 7 Significant Process Control usages Liquor Filtration Master Sequence Dig . Feed Pump Cross-over Coal Mill 1A sequence abort Incorrect control action – Hydrate Flow Condensate Alarm rationalization Alternative design in Boilers to reduce RegPV’s Developed Standardized Work Practices for Calcination CRO’s Simulator Benefit Case Studies Digestion feed pump interlocks/trips - one of the refineries key safety controls - significant potential for equipment damage - significant potential for environmental incident Case 1: JPU Jump-over Case 2: 7th digestion slurry feed pump –swappable spare - simulator testing - verification of HPM Code - DCS testing - problems encountered CAR Digestion Trains Digester Feed Pumps Case 1: JPU Jump-Over Failure of 2 crank shafts in digestion slurry feed pumps of unit 1 Feeding one unit 1 digester from unit 2 feed pump Lost production due to having a whole unit down - flah tanks require that there be at least 2 trains on per unit Would involved leaving a unit offline for extended period Jump-over was in place for about 3 weeks ~7 days production From Decision to proceed to commissioning was 3days Pig Catching Station Case 1: Logic Connections Case 1: JPU Testing Procedure Using simulator , tested feasibility of jump-over from unit 1 train 1 to unit 2 train 1 - preliminary tests done to determine viability - unit start-ups and trips - was done in ~ 3 hrs Management decision to implement was late Wednesday afternoon Simulator configuration and logic on simulator configured late Thursday afternoon Testing of interlocks and control was done on the Friday morning Implementation and Testing on DCS done Friday afternoon Commission 11pm Saturday night 13 configuration changes, approximately 50 graphic modifications and 1 CL modification 24 trip/interlock tests to confirm logic connections Management sign off on risk based on quality of simulator testing Benefit: 14 days of 50% plant production Case 2: 7th Digestion Feed Pump CAR originally had 6 pump – 1 per train, no spare 7th – Spare that can operate in the duty of any of the other 6 Goal – reduce downtime of digestion trains because of pump availability Over 600 interlock tests carried out to prove logic Significant change to be done to an online plant All tests pre-done on simulator - prevent config errors on-line - only suitable platform to do large scale testing without plant impact No production loss associated with the logic changes Other forms of testing would have delayed the project – and cost production. The 7th pump was used 15 times in its 1st month of operation – significant production impact Case 2: Schedule DCS design meeting held early February - had to redesign all of the logic associated with the 6 existing pumps to allow for the interconnections to the digestion trains and the 7th pump Operations requirement for operator training by April - logic design had to be finalised quickly - simulator implementation completed on schedule. - decision made to test all control and interlock strategies in simulator - again completed before operator training 7th pump onsite late March 7th commissioned 1st week May Case 2: Logic Diagram Case 2: Modification Scope Unit based interlocks Will trip the whole digestion unit. 7th can be lined up to either of 2 units Train based interlocks Trips train when things like back pressure Hi. 7th can be lined up to any of 6 trains Pump based interlocks Some of the interlocks are in PLC and some in DCS. Feedfoward control signals Back pressure and feed tank levels Alarm strategies Contcutting of alarms on offline trains CL changes Decoding of PLC data Graphic modifications Status displays, operator displays Case 2: Implementation of Changes Large scale change - ~ 16000 lines of EB source involved in the change - ~ 150 HPM points - 7 existing graphics - 5 new graphics Built basic code in DCS for 1 of the pumps - didn’t impact on online trains Edit EB files to generate first pass of code for all of the pumps Loaded EB’s into the simulator Made modifications in the simulator as a result of testing Strict version control on EB source - EB files kept close to code in the simulator - not an automated process Pump Status Display Start Permissive Graphic Testing of Code – Simulator Example of Text Matrix Case 2: verification of code Ensuring code in DCS was what was tested in simulator Built a dummy set of simulator code from EB files Copied the actual simulator code from the simulator configuration Compared using CSDiff Reviewed and discrepancies so that the code to be loaded on DCS was the same as simulator code Implementation/Testing on DCS Changes on DCS had to be done when each digestion train was down Usually had between 1 hour and 1 day notice of when the pump would be down Repeated a similar set of interlock tests on pump after logic modifications on DCS Unit interlocks could only be tested if the whole unit was down. Approx 50 tests to be done on each train Tests took typically 2 hours to perform – production critical No surprises – no production loss because of delays fixing logic – due to pre-testing on simulator Problems Encountered 1 minor error detected in DCS code after implementation - forgot to re-setup an Automan block to allow external swiching Poit was not in scope of original changes 1 minor testing mistake on DCS - forgot to put an LIC back into PVAuto after testing. Overflowed a small amount of caustic Lessons Learnt Significant project and testing required. Simulator performed well for this task. - easy to reconfig when errors found -simulator model changes were fast, did not hold up project Simulator enabled comprehensive testing - not possible on real system with-out stressing plant or causing a production loss DCS implementation went well - no production loss during of DCS implementation - simulator eliminated live config changes to correct errors Simulator testing identified a line-up start permissive -preventing pump from starting when line-up isolations incorrect Verification difference in automan block (EXTSWOPT) was not part of original scope. Conclusion Simulator testing was a good way to implement project Simulator not just a training tool – even in a running plant Comprehensive testing of new code in a running plant is difficult Likely that logic errors would have been made without the comprehensive testing on the simulator |
