1) What all we check while issuing a confined space permit2)How much is the Minimum requirement of Oxygen3)What is the TLV,STEL and IDLH of Hydrogen sulphide4) How to prepare an equipment for hot work5) While issuing an excavation permit what all precaution's we have to take6)Start up of centrifugal compressor7) What is surging in a centrifugal compressor ? How it occur's ? How is antisurging done ?8) What is hamerring? Steam and defferent pressures and temperatures, superheating.Following defnitions:1) flow - units 2) pressure- units 3) temperature-units, conversions of units.Absorption & adsorptionPumps & typeswhat is NPSH?compressors & typesGeneratorsturbines (types) Steam, gas, combined cycle-- condensing, ...... etcExchangers -- types Shell, tube, baffels, finfanThermocouple & RTD (resistance thermometerdevice)Basic knowledge on DCS systems.(distributed control system)Controlers - typesShut down systemsPermit to work systems. (hot work, cold work, open flame mainly 3 types) others all certificates attached to the permits. like excavation, Flow rateCalorific valuewhat is the purpose of lubrication oilDensity - unitsViscocity -- UnitsPHAnode protection & cathodic protectionFlash point, ignition Temperature, Auto ignitiontemperature (values for H2S, Methane)Filtration - types of filtrationabsolute temperatureDewpoint & Atmospheric dew pointCurrent -- Units -- types (AC/DC) step up transformers/ step down transformers.AmpereHeters , types of heat transfers (covection, conduction, Radiation)Joul thomson effectSpecific heat & latent heatStorage tanks and types ( for Cruid oils , LPG, LNG)Cavitation -- effects of cavitation & how to controlWhat is corrosion? types of corrosion? preventive methods.Simple mathmatics with limited time.Write an essy on your plant systems, start-up or shut down in simple with good wording (criteria easy to understand to all, gramer, hand writing, clear masage with 10 to 15 centenses)Reading of P & ID's (need to understand all sybols of valves,equipmets,directions,links to next pages, signals, line specifications, data given on P &ID like design & operating, importance of notes, revisions, P & ID numbering.Prepare any of your unit to draw a flow chart. For example absorption or regeneration or compressor loop or distilation or boiler.Criteria is drawing to be neat, good look, all main equipments and controlers with control points(signals)other monitoring parametres (like PT, TT, LT,FT, DT...) numbers are not too important.
