Job Purpose
Analyze and execute hydrocarbon mass balance reconciliation for Refinery and Cracker and Petchem Complexes (RCPC Complexes), excluding INA Complex, through:
i) effective implementation of validation methodologies and mass balance principles to ensure timeliness, completeness and accuracy of data can be furnished to relevant stakeholders.
ii) seamless integration between mass balance application and data providers with minimal manual intervention for reliable hydrocarbon movement and mass balance tracking
Key Accountabilities
Hydrocarbon Accounting & Reporting
Track, analyze, prepare and issue required mass balance reports for RCPC Complexes which includes:
i) Daily report on feed/intermediate/product inventories and production numbers for the purpose of plant performance monitoring.
ii) Monthly Inventory Movement Report for the purpose of financial month-end reporting, assessment and billing purposes.
iii) Daily and monthly Production Report for the purpose of yield tracking and production numbers using reconciled figures as input to LP, APS and economic assessment.
Identify and propose alternative figure for unreliable and irregular data for reporting purposes. Establish and comply with process flow on data management to ensure any issues can be addressed to the relevant parties. Provide input and facilitate in data validation relating to custody meters, production levels of each unit, shipments and receipts.
Hydrocarbon Loss Tracking & Reporting
Track and analyze hydrocarbon loss which includes both accounted and unaccounted loss figure for the whole complex on daily basis through identifying the source of losses and possible recommendations to improve/minimize hydrocarbon loss.
Identification of Flow Meters Performance
Monitor and track the performance of operational and custody flow meters (measurement) by identifying faulty meters relevant to mass balance. Verify the reliability and accuracy of measurement from flow meters and highlight any irregularity to the rightful party. Generate Gross Error Report (list of flow meters where the reconciled figure deviates more than a certain acceptable limit) using 1) mass balance application, if available or 2) manual consolidation of such meters for instrumentation rectification work.
Molecular Management Tracking & Reporting
Analyse and execute the implementation of Molecular Management, developed to support following key functionalities and generate/prepare relevant reports:
i) Crude Composition tracking to support scheduling and operations to achieve the optimum crude mix charged to crude distillation unit.
ii) Monitoring of allocated product inventories held by each Offtaker (shareholder), where by allocated inventories indicate a right to purchase and lift product from RCPC Complexes.
iii) Develop reconciled Raffinate-2 butene delivered to INA.
iv) Capture of reconciled RCPC off gas and fuel gas exchange between production facilities and PRPC-UF on mass balance and report calorific value transferred to PRPC-UF based on online analyser.
v) Support development of an accurate hydrogen (H2) balance to support accurate performance monitoring and identification of excess hydrogen consumption and losses.
Error Solver Model Maintenance
Perform mass balance reconciliation using mass balance application. Utilize the application features to identify any errors and close any gap in terms of the reliability of the data. Verify model configuration in the application to follow physical and actual configuration at site. Identify any missing streams, routings, design info and tags in the model to ensure accurate representation of the plant configuration and notify relevant parties to close the gap.
