Hello, Experts,
Generally, we look certain variables for any new crude oil approval in petroleum refinery like , LPG H2S,TAN,Total Sulfur,Desalter related issues,CII etc.
In typical crude oil basket, where 8-10 crudes are being processed ,how to optimize any new crude oil approval process...
Hi, everyone,
after long time...I could find very good correlation for response of Naptha splitter overhead CS2 in light naphtha Vz. crude such as Eocene wt % of crude processed in the feed and wt % of Ras Gharib crude processed in the feed and coincidently these crude is having very high...
Dear Milutin,
This light naphtha goes for sell quite often so, that’s why it is area of concern .In fact, inlet crudemix window consists of quite different types of heavy & light crudes and apart from that few of the crudes have been analyzed in the past for inlet carbon disulfide once (no...
Dear all members,
Very good morning to all of you !!
Carbon disulfide(CS2),which is sulfur derivative impurities being reported in light naptha of naptha splitter overhead situated at downstream of crude/vaccum/gas con unit.
Lot of theories are there for formation of corrosion speicies in...
Just to give insight into,Propylene ( mainly from FCC & small part Coker LPG ) from propylene recovery unit passes through treatment process through regenerative and non regenerative type catalyst/adsorbents which convert upstream sulfur impurities those come as part of refinery processes like...
Hello…Everybody…
The polypropylene is one of the product which is produced by polymerization process (loacated in downstream of refinery process units ) in fludized bed reactor by using propylene is main raw material which comes from refinery. This propylene is predominantly comes from FCC &...
Hi everybody !!!
Very warm regards to all of you,
In coker complex ,the coke drums overhead line which goes to coker fractionator this transfer line is prone for coking and that is why to maintain temperature around 430 C,quenching is also being provided through Light coker gas oil (LCGO) ,at...
Hi..everyone !!!!
Is it possible to get Benchmarking value or best possible achieved value of ring loss in Tatoray unit of petrochemical complex ( Aromatics complex ) : Downstream of petroleum refinery.
Thanks in advance to all of you !!
Normally,
There are total 4 packed section – LVGO ,LVGO Circulation,HVGO & slopwax packed bed section.HVGO IR on below section is being maintained around 205 m3/hr ,It is damp vacuum condition i.e. 20 mmhg top section & around 32-34 mmhg vaccum at flash zone section.Yes,In the bottom VR quench...
Hello.everybody..
The vaccum crude distillation unit is having two similar trains of similar capacities and processing the same crudeblend with the same operating window.Now the question is how do one should structurally analyze the difference in the variations in the IBP of Vaccum residue...
Dear all,
I heard about EU – REACH which is related about regularization & registration of the chemicals/petrochemicals and petroleum refineries’ related products which goes to Europe.
Has anybody aware about that what is the procedure to be followed to register petroleum products like...
Hi everybody,
In petroleum refinery in addition to implementing pinch in certain potential area & in addition to usage of air coolers,there are cooling water exchangers installed in the process units like in CDU,P-XYLENE Aromatics complex,FCC,Coker etc. Is there any potential area where we can...
Oh..yes,
dcasto & 0707,
Failure Mode effect analysis -FMEA & QFD is also one of the good six sigma tools which one can deploy..I have just gone through qualproinc..really intresting one..
As 0707 mentioned, RPN = severity x occurance x detectability is really vital tool..any buddy has...
