概要
EXPERTISE & ACHIVEMENTS:
➥ Created single sqlite .db as a standalone relational database for previously 3 separate cell rooms (x9 Electrolyzers | x12 HCl furnaces), 3 separate brine systems & 3 Absorption chillers (with tons of separate spreadsheets) which now can be analyzed/correlated in terms of lab data, maintenance history, material consumptions, current efficiencies... Above quantitative relationships now made cost-efficiency possible through in situ process optimization, for instance by making water turbine & Freon compressor set-points ‘dynamic’ I saved ~370kWh on daily basis
➥ Conducted Process research and analysis (computer aided simulation/statistical process control) that tests the technical feasibility & or optimizes, design, operation and performance of equipment, components and systems. I have applied these skills in pipe network re-routing for compressed nitrogen/air circuits to reduce pressure losses & increase occupational safety. I was able to create fitting distribution curves to hundreds of electrodes for deducing predictive health decay models, leading to accurate budget & energy planning. For the fiscal years 2015 & 2016 my proposed electrical energy requirements for electrolyzers fell between the accuracy of ± 3%
➥ Trained fresh engineers & operators with a ‘look-see’ approach by building mockups of DCS/PLC & process networks using dynamic models in Geogebra & VBA driven Excel spreadsheets. My DCS mockups slashed training periods from 12 months to less than 4 months, it also lessened operator post-turnover headache majorly faced by HR
➥ Defeated ‘raw materials consumption’ face-palming my managers by Resource Monitoring (via SAP ERP) and avoiding/minimizing resource-hoggish processes
➥ Pointed out ‘make-believe’ chemical/equipment suppliers based on usage/maintenance averageness
➥ Saved hours in development jobs by meticulous scheduling via infographics of resources/manpower
➥ Deciphered cyclic problems faced by shift/maintenance engi

工作经历
Senior Chemical Process Engineer
Following sections are the major units that I command (as shift in charge as well as process analyst)
➥ UHDE Cl2 Electrolyzers (430MTD) – Carefully averaging outlet cathoyte/anolyte temperatures (utilizing immense heat of formations) I reduced steam consumption to preheat feed brine as well as cooling loads to precool feed caustic
➥ Asahi AKC Cl2 Electrolyzers (180MTD) – Rated heated air coils such that entering N2 temperature is well above 60ºC at electrolyzer tripping condition to avoid membrane thermal shock while ensuring adequate N2 flow rate
➥ CAUSTIC 50 w.t% EVAPORATION (570MTD) – Recovered tons of slightly alkaline but low TDS process condensates & used it as feed RO water after HCl pretreatment
➥ HYDROCHLORIC ACID PLANT (300MTD) – 35 w.t% hydrochloric acid production by combustion of hydrogen and chlorine gas in furnaces designed by SGL Carbon-Germany & Carbone Lorraine-France
➥ ANHYDROUS LIQUID Cl2 (35MTD) – Monitoring three Freon compressors for any mechanical overhaul & maintaining COPh of at least 2.8
➥ ABSORPTION CHILLERS (1070TR) – I oversee two YORK double effect machines each 400TR & one YORK single effect machine of 270TR. Machine performance history as well as solution chemical health are comprehensively logged & scrutinized for timely assessment & troubleshooting
➥ COMPRESSION CHILLER (260TR) – Of the 5 total Na-hypo batches at least 3 are always online & generating a plan to extract heat optimally is key to manufacture batches of varying Cl2 concentrations on schedule
➥ WATER TREATMENT – Maintaining key performance indicators of 2 RO & 3 Demin systems including Conductivity tests, Langelier index, pH, Recycle ratio, Regeneration frequency, Multistage pumps ampere/noise level …
➥ COOLING TOWERS – Totaling a tonnage in excess of 2000TR I manage 3 Hamon-French cooling towers including inhibitor concentration, blowdown durations/frequency & guaranteeing 4 to 6 cycles of concentration for optimizing make-up water quantity. In addition mec
