CH3002 Primary Refining Technology Syllabus:
CH3002 Primary Refining Technology Syllabus – Anna University Regulation 2021
OBJECTIVE
The course is aimed
1) To enable the students to learn the methodologies in the primary petroleum refining processes like crude preparation, atmospheric and vacuum distillation, Lube, asphalt and wax processing.
2) To enable students to examine how each refinery process works
3) To enable students learn each operating variables are applied to achieve the objectives of each refinery process
UNIT I FEED PREPARATION
Pipelines from port to tank farm -safety and regulations -storage techniques in crude oil-impurities removal- measuring by dipping -spiking techniques -types of salts in crude – desalting process – electric desalter- preheating train and design- furnace and its operation.
UNIT II ATMOSPHERIC DISTILLATION
Operation and process description of ADU-design characteristics of ADU tower-cutpoints-degree of fractionation-over flash-column pressure and overhead temperature- Preflash systemoverhead system-side streams-intermediate pump around and reflux systems- Refinery off gas – LPG treatment-Naphtha stabilizer and splitter-side stripping sections-operating variables
UNIT III VACUUM DISTILLATION
Operation of VDU- Need of vacuum- ejectors and its types/principle- Overhead ejector systemflash zone- draw off temperature- internal flow in VDU- light/middle/heavy cuts- routing to secondary units- lube based treatments-packing section tower loading of VDU
UNIT IV LUBE OIL BASE STOCKS
Viscosity index calculation and pour point – LOBS processing by solvent treatment and hydro treatment- solvent selection-solvent extraction by NMP,furfural,- MEK solvent dewaxing/- refrigerating and filtration -hydro finishing- types of LOBS based on VI- types or groups of lube processing-spindle/LN/IN/HN/BN processing and blending.
UNIT V ASPHALT AND WAX TECHNOLOGY
Vacuum residue properties- propane deasphalting-asphalt processing and types-chemical structure-air blowing of bitumen- slack wax processing- wax and types/properties- wax deoilingunit operations in wax plants- refrigerating and filtration/ hydro treating of wax- molding and storage
