Conceptual Study
Petrogas Jahan provid provides conceptual studies that evaluate technical options prepare preliminary process design, estimate costs and define project requirement.
Our Approach to Conceptual Study
1. Data Collection & Review
Gathering available feedstock data, process requirements, and site conditions.
2. Process Evaluation
Scenario Development and Theme Screening, Performing initial simulations and licensor assessment.
3. Preliminary Design
Producing BFD, Process description, Developing high-level process flow diagrams (PFDs), material balances, Utility Consumption and equipment sizing.
4. Cost & Schedule Estimation
Preparing conceptual-level CAPEX/OPEX estimates and indicative project timelines.
5. Risk & Feasibility Analysis
Identifying technical and economic risks, along with optimization opportunities.
6. Final Report
Delivering a clear, decision-ready document to guide FEED and EPC phases.
Basic Design Engineering
In this stage, we translate the project concept into a clear engineering basis. Our team prepares process flow diagrams (PFDs), utility requirements, material balances, and preliminary equipment sizing, along with safety and environmental considerations.
This provides the foundation for Detailed Design and ensures that all project stakeholders share a common technical understanding before execution.
Basic Design Engineering – Our Process
1. Concept Endorsement
Endorsement of conceptual studies report.
2. Process Flow Diagrams (PFDs)
Development of PFDs based on conceptual study and technology selection.
3. Material & Energy Balances
Defining process requirements, heat and mass balances, and utility demands.
4. Preliminary Equipment Sizing (Equipment List)
Estimating major equipment capacities and preparing basic datasheets.
5. Process and Instrument Diagrams (PIDs)
Development of 1th issue of P&ID’s
6. Utility & Offsite Requirements
Identifying needs for power, water, steam, fuel, and other essential utilities.
7. Safety & Environmental Considerations (HAZOP/HAZID)
Integrating HSE standards, flare and relief systems, and environmental compliance.
8. Project Definition Package
Delivering a consolidated package that provides the technical basis for Detailed Design and reliable cost estimates.
Front-End Engineering Design (FEED)
FEED defines the technical scope of a project before moving into detailed design. Our team prepares confirmed P&IDs, equipment datasheets, plot plans, and accurate cost estimates.
This phase reduces risks, improves budget reliability, and ensures a smooth transition to EPC execution
Our Approach to FEED (Front-End Engineering Design)
1. Data Collection & Review
Gathering process data, feedstock characteristics, site conditions, and project requirements.
2. Process Design
Developing and confirming process simulations, material & energy balances, and P&IDs.
3. Equipment & Specifications
Preparing datasheets and preliminary specifications for critical equipment and systems.
4. Layout & Plot Plans
Designing plant layouts, utility integration, and infrastructure requirements.
5. Cost & Schedule Estimation
Delivering accurate CAPEX/OPEX estimates and a realistic project schedule.
6. Risk, HSE & Regulatory Compliance(HAZOP/HAZID)
Conducting risk assessments, HSE studies, and ensuring compliance with industry codes and standards.
7. FEED Package Delivery
Providing a comprehensive engineering package that forms the basis for Detailed Design and EPC execution.
Detailed Design Engineering
At this stage, our team transforms the basic design into full construction-ready documents. We deliver detailed P&IDs, equipment specifications, civil/structural drawings, electrical and instrumentation layouts, and 3D plant models.
The outcome is a complete package of Approved for Construction (AFC) documents and procurement deliverables, ensuring a seamless transition to the EPC execution phase.
Detailed Design Engineering
1. Basic Endorsement
Endorsement of Basic Design report.
2. PFD, UFD, Piping & Instrumentation Diagrams (P&IDs)
Development of detailed PFD, UFD, P&IDs based on approved Basic Design, covering all control and safety systems.
3. Equipment Specifications & Datasheets
Finalizing datasheets, mechanical drawings, and vendor specifications for all major and auxiliary equipment.
4. Civil, Structural & Architectural Design
Preparing detailed layouts, foundation drawings, steel structures, and building requirements.
5. Electrical & Instrumentation Design
Complete electrical load lists, single-line diagrams, cable routing, instrumentation layouts, and control logic.
6. 3D Modeling & Plant Layouts
Developing integrated 3D models to optimize plant layout, piping routes, and accessibility.
7. Process Safety Studies (HAZOP / HAZID)
Conducting hazard identification and operability studies to ensure compliance with international safety standards.
8. Construction &
Issuing AFC (Approved for Construction) drawings, MTOs (Material Take-Offs)
9. Procurement Deliverables
Providing Material Requisitions (MRs) for procurement.
