Process to blend a mineral derived hydrocarbon product and a fischer-tropsch derived hydrocarbon product

Abstract

A process to blend a mineral derived hydrocarbon product and a Fischer-Tropsch derived hydrocarbon product is disclosed including the step of providing in an Above Ground Storage Tank a quantity of mineral derived hydrocarbon product and Fischer-Tropsch derived hydrocarbon product such that initially the mineral derived hydrocarbon product is located substantially above the Fischer-Tropsch derived hydrocarbon product.

1 . A process to blend a mineral derived hydrocarbon product and a Fischer-Tropsch derived hydrocarbon product comprising the steps of: providing in an Above Ground Storage Tank a quantity of mineral derived hydrocarbon product and Fischer-Tropsch derived hydrocarbon product such that initially the mineral derived hydrocarbon product is located substantially above the Fischer-Tropsch derived hydrocarbon product.  
   
   
       2 . The process of  claim 1  wherein initially at least 50 vol % of the Fischer-Tropsch derived product is present in the lower half of the Above Ground Storage Tank.  
   
   
       3 . The process of  claim 1  wherein more than 50% of the boiling ranges of the mineral and the Fischer-Tropsch derived products overlap.  
   
   
       4 . The process of  claim 2  wherein more than 50% of the boiling ranges of the mineral and the Fischer-Tropsch derived products overlap.  
   
   
       5 . A process of  claim 1  wherein the mineral hydrocarbon product comprises a crude mineral oil, a gas field condensate, a plant condensate or naphtha, kerosene, gas oil, vacuum distillate, deasphalted oil or residual fraction of crude oils.  
   
   
       6 . The process of  claim 5  wherein the blended product is a blend of a mineral crude oil and Fischer-Tropsch syncrude, a blend of Fischer-Tropsch derived naphtha and gas field condensate, a blend of Fischer-Tropsch derived gas oil and mineral derived gas oil or a blend of a Fischer-Tropsch derived waxy raffinate and mineral oil derived vacuum distillate and/or mineral oil derived deasphalted oil.  
   
   
       7 . A process of  claim 6  wherein a blend of Fischer-Tropsch derived gas oil and mineral derived gas oil is prepared.  
   
   
       8 . The process of  claim 7  wherein to the blend additives are added while emptying the blended product from the Above Ground Storage Tank.  
   
   
       9 . A blended product produced by the process of  claim 1 .  
   
   
       10 . A blended product produced by the process of  claim 9.
