One of the major component for Petroleum Refinery "Unaccounted loss" is Receipt Crude BS&W at Tank farm from Jetty through Ship.Is there any best practices/methodology for Crude BS&W accounting in Refinery overall yield accounting methodology. There are various steps for Crude BS&W measurement...
Organic Rankine Cycle application is one of the very good energy saving measures , however, Generally speaking, its payback is not much economical. Any proven case study in Petroleum refinery or Captive power plan where this is proven and beneficial?
Thanks & Regards,
Limestone as CaCO3 and Fly ash (Coal Fly ash) are used as flux in Petcoke(High Vanadium content) Gasification unit under reducing atomsphere to minimise fusion temperature of petcoke. The fusion temperature is important as it affect the refractory life. Petcoke quality remains more or less...
Is there any Online analyzer available which can monitor Saybolt number (Colour) in the ATF/Kerosene Merox outlet product stream.ATF/Kerosene Merox converts RSH to disulfide, during the process colour degradation happens.
Thanks in advanced.

Crude Furance burner tip has issues of white deposition (Fuel gas fired burners) on burner tips. Is there any preventive measures to avoid such thing as due to this deposition, high back pressure and uneven heat flux is being observed.
Normally wash water is used to wash ammonium and cynaide salts in overhead vapour line (upstream of condenser) in Delayed coker fractionator.Is it technically feasible /viable to replace this stream with hydrocarbon instead of water.
HP steam is generated from waste heat boiler at two places in Sulfur unit of the Petroleum Refinery one at reaction furnace and another at incnerator downstream equipment.This saturated HP Steam(261 deg C-Design value) is routed to Superheater where it is superheated to 391 deg C(Design...
Once through /Natural Thermosiphon Reboiler where we know that it has got the impact of liquid level on its heat transfer rate and its performance.
For Atmospheric splitter column , where this reboiler is operated, has bottom baffle.Now when we want to assess reboiler sump level vis a vis heat...
Heavy cracked naphtha which is produced in Fludiesed cataltic cracker plant having IBP is 150 deg C and FBP is 220 degc.Is there any technical issue replacement of MP steam with LP steam for energy saving.
Thanks and Regards,
Petroleum Refinery integrated with Petrochemical complex has its own captive power plant(CPP-Cogeneration).CPP generates and distribute power and steam to the refinery and petrochemical complex.Which is the appropriate method to calculate the Heat rate and steam cost which gives the true and...
Phenolic sour water stripper is having thermosyphon reboiler.unit capacity is to strip off 180 m3/hr phenolic sour water having H2S 0.3 wt % in feed and outlet striped water is having less than 30 ppm h2s.lp steam is used in reboiler.temperature is checked as 160 degree c at the inlet of...
We are facing difficulty to reduce carbonyl sulfur (COS) in propylene product ex Propylene Recovery Unit from LPG ex FCC and Coker Unit.We are using Merox process for LPG Sweetning.
The Total sulfur in Merox product outlet is in the range of 7 to 9 ppm.
Request you to suggest remedial...
Shell and Tube heat exchangers : BEU .
Tube side service : MP Steam / 16 kg/cm2g.
