PROCESS & OPERATING PHILOSOPHY
Feed heating, catalytic reaction, high-pressure separation and stripping. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
REFINERY UNITS
Kerosene Hydrotreating (KHT)
Hydrogen treatment to control sulfur, smoke point, color and stability as required.
MAIN EQUIPMENT & PACKAGE LIMITS
Reactor, heater, exchangers, separator, stripper, compressor and product cooler. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
CRITICAL DESIGN INPUTS
Feed assay/composition, design capacity, operating pressure and temperature, product specifications, turndown, utilities, battery limits and site ambient conditions.
ENGINEERING DELIVERABLES
Feed/product specification matrix, catalyst basis, utility balance and performance test method. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
AUTOMATION, SAFETY & HSE
DCS regulatory control, critical interlocks, relief and depressuring, gas/fire detection, hazardous-area classification, HAZOP actions and applicable SIS/ESD functions.
APPLICATIONS & PERFORMANCE BASIS
Jet/kerosene upgrading and blend-component production. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
ASTM product methods, API, ASME and hydrogen-service practices. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
CONTRACTUAL CODE BASIS
ASTM product methods, API, ASME and hydrogen-service practices.
