  1. “azbil” Solutions for Alumina Refining Plant Al2O33H2O + 2NaOH 2NaAlO2 + 4H2O White side: Scaling problems Dissolve bauxite in caustic soda. Digestion Crushing and transport Mining Red side: Wearing problems Clarification Remove solid residues from the liquor. Spent liquor Convert to alumina by removing water of crystallization from the alumina hydrate. Form and recover of crystals of alumina hydrate from the liquor. Calcination Crystallization 2NaAlO2 + 4H2O Al2O3•3H2O + 2NaOH Al2O3•3H2O Al2O3 + 3H2O Electro-magnetic Flow meter Pressure Transmitter Smart Valve Positioner Special Control Valve Integrated Open DCS

  2. azbil Open System Platform with a variety of Solution Packages Yamatake Solution Vision with System Platform PM-EX AMC PM100 Knowledge Power Alarm Analyst PREXION, MIB Electric Shift Log Utility Optimization 3rd party system Integrated HMI DOPC DGFC DGPL PlantWalker-HV Field Client Ex Proof Field Client OperationAnywhere

  3. Personalized window presentation images… MIB- For Manufacturing data visualization For Manufacturing Manager For Manufacturing Stuff For Shift Leader • Distill data in multiple sources into useful data • Personalize useful data for each individual meeting their role and responsibility SOP Shift Log Batch History Plan/Performance Order/Ship Quality Labo Asset Data

  4. PREXION – For production monitoring Infrastructure of production Information system Process historical information user can utilize the information at any time and any accuracy depending on their work. Production Control Facility Management Operation Management Quality Control Technology Control Site performancefor Plant Manager Process performancefor Shift Leader Production performancefor Production Engineer

  5. Alarm Analyst - Correlation analysis Alarm Analyst R20 Correlation Analysis;- Easy to build Knowledge-Base alarm & event model… unique technology From alarm & event historical logs, Correlation Analysis extracts ;- • Event groups consisted of the alarms and the operation actions in a process upset • Propagation path • Source origin • Nuisance alarms • Total counts in Alarm & Event group • Information about Alarm & Event group structure • Cause & Effect relationship • Cause of alarm flood or complex operation is estimated using order of events occurrence.

  6. Gasket Electrode Mirror finish liner Liner SpringAssembly MagneW3000:Solution for Scaling (adhesion problem) • 1. Field replaceable electrode • Cleaning electrode can be done in the field. • 2. Mirror finish liner • Mirror finish liner solves the scaling problem.

  7. Mirror finish liner - It is proven that no adhesion occurred on the mirror finish liner surface. Replaceable electrode structure Gasket New liner manufacturing technology - Patent pending Electrode Conventional type surface roughness MagneW 3000 PLUS surface roughness Liner SpringAssembly No adhesion MagneW3000:Solution for Scaling (adhesion problem)

  8. Zero-drift ＠ 125℃ AT9000(GTX): Long-term stability • azbil’s new sensor has realized excellent zero-point stability. 0.10 0 -0.10 Competitor A Data Competitor B Spec.@28℃ Error(%FS) azbil’s new sensor@125℃

  9. azbil Solution-oriented Control Valve For Alumina Slurry Customers : Alumina Refining Plant

  11. Isolated design between electronics and pneumatic circuits This design eliminates troubles caused by dusty and humid air quality. Instrumentation air and outside atmosphere do not come into the electronics circuit department. SVP3000: High durability and stability Pneumatic circuits Even if the atmosphere is corrosive and instrumentation air is not perfect, it does not affect the electrical part of the positioner. Electronics circuits Isolated design between electronics and pneumatic circuits
