Thermodynamic Modeling, System Hydraulics & Flow Schemes
Process engineering forms the fundamental foundation of any safe, energy-efficient chemical or hydrocarbon production plant. COREX Engineering provides end-to-end process design capabilities, from early conceptual feasibility studies and Aspen HYSYS simulation through to detailed Process Flow Diagrams (PFD), intelligent Piping & Instrumentation Diagrams (P&ID), and safety relief valve calculations.
Our senior process engineers combine thermodynamic theory with operational field insight to optimize equipment sizing, minimize utility consumption, and ensure fail-safe overpressure protection.
Key Technical Deliverables
Steady-State & Dynamic Simulation
Thermodynamic modeling in Aspen HYSYS and Aspen PLUS with heat and material balances (HMB) for all operational cases.
Intelligent P&IDs & Flow Schemes
Development of complete P&IDs with line numbers, valve tagging, control loops, interlocks, and design pressure/temperature boundaries.
Hydraulic Network & Line Sizing
Single and two-phase pressure drop calculations, erosional velocity limits (API 14E), and pump suction/discharge hydraulics.
Process Equipment Datasheets
Process datasheets for pumps, compressors, separation vessels, column internals, heat exchangers, and filters.
Overpressure Protection & Relief (PSV)
Contingency relief scenario evaluation conforming to API 520 / 521 (fire case, blocked discharge, tube rupture, power failure).
Flare Header & Depressuring Audits
Blowdown simulations, backpressure calculations, and flare network verification to prevent cryogenic low-temperature embrittlement.
