CFPP Prediction for Diesel Blend

CFPP Prediction for Diesel Blend

CFPP Prediction for Diesel Blend

(OP)
Dear all experts,

The diesel grades are being manufactured in typical petroleum refinery where,various 8 to 10 types of crudes are utilized to make a blend window to produce diesel and the important property of diesel is Cold flow property CFPP ,where additives are used to improve CFPP but the question here is to predict CFPP or to know CFPP well in advance so, that dozing of CFPP can be fixed up as per desired CFPP value.

Is there any method to predict CFPP or to minimize CFPP additive consumption ?

I think I could see some of the articles during googling but it says that , individual Diesel blending stream should have CFPP ,I think there is some way to predict CFPP through Crdue Pour point/visocity ?

Kindly share your valuable ideas..

Thanks in advance to all of you...

With warm regards,
Yours faithfully,

Suggest you contact the principal suppliers of pour point depressants such as Baker-Hughs, GE Betz, Nalco to name a few, as they have decades of experience dealing with cold flow properties of distillate fuels and the predictability of this property.

Not sure if this is useful but my company manufactures ATEX approved Cloud point analysers (online for petrochemical installations/refineries). The CFPP is generally 3-8oC below that of cloud so if you have the cloud point you can roughly predict where the CFPP will be.

Good idea orenda

Engineers like to solve problems. If there are no problems handily available, they will create their own problems.
