Dear All,

My name is Mohammed , I am still new to this field which is Lubricants …..

Here is my situation & what I need from you guys to recommend it to me …

 

All of us we know what we mean by ( Lubricant Blending Process ) which is :-

 

Lubricant blending process ,  comprises mixing different materials boiling in the lubricant boiling range to make a final homogenous product. Usually a higher viscosity lubricant will be blended with a lower viscosity lubricant to achieve a blended lubricant of intermediate viscosity.)

Here in my country – Egypt -  , I have studied the Market , and I found the most required products are following :-

•  ( 20 W 50 – SL  ) – ( 5 W 30 – SN  ) – ( 15 W 40 C I 4 ) – ( 15 W 40 CH 4 ) – ( 20 W 50 CH 4) –( Hydraulic 68 ) – ( CF 50 ) – ( CD 50 ).

For more information , I have the Formula for ( 20 W 50 – SL ) & let me share  it with you as an example .

Because I need to know how to prepare it in the Production environment (blending Vessel) .

• Base Oil ( virgin base oil ) – SN 150  = 8.5 %.
•  Base Oil ( virgin base oil ) – SN 500  = 75.9 %
• SL/CF PACKAGE ( from Additive company called – Lubrizol ) = 6.5 %
• Viscosity Index Improver ( VII ) ( from Additive company called – Lubrizol ) = 9.0 %
• Pour Point depressants ( PPD ) (  from Additive company called – Lubrizol ) = 0.1 %.

 

Here is my question , I want to know if there is any Training I can Attend by myself to know how to prepare the product ( 20 W 50 SL ) on small scale first using digital magnetic stirrer hot plate in my Lab as first step.

 

As second step once I make sure the sample which I prepared is correct and it meet the requirements of ( 20 W 50 SL )  , I will Immediately implement on Big scale which is in blending vessel which is almost ( 5 Metric Tons = 5,000 LTR ) .

 

My question in very simple way , which one is put first , then heat to which degree , then add what else , then do what else as next ? shall I put ( SN 150 ) first , or ( SN 500 First ) and then do the blending while the heater is working & to which degree ? should be 80 degrees Celsius , or what ?

 

Can anyone recommend also good institute can teach me how to prepare / Implement the Products ?

I have all the required formulas , from Lubrizol & Unfortunately , I am the only one who is supervising this project .

Please advice me ASAP .

Regards,

Dear Mohammed,

You may read the book 'Lubricant Blending and Quality Assurance' by R.David Whitby for understanding every process in lubricant blending and its quality assurance. This book is published by CRC press.
