Feasibility studies for conventional refinery distillation with a (1 : 1) w/w of a biocrude blend with petroleum crude oil
Biocrude produced by the catalytic cracking of plant seed oil has the potential for use as a substitute of petroleum crude oil. The distillation characteristics of a biocrude blend prepared by mixing 50 wt % of Oil India Limited (OIL) petroleum crude with the biocrude prepared from the methyl esters of Mesua ferrea L. seed oil are reported in this paper. More than 63% of the distillate can be recovered from the blend at atmospheric pressure, compared to 43% for the OIL crude. The recovery of aviation turbine fuel (JP-8), which normally has a boiling range of 175-250 degrees C was determined to be much higher: 26% in biocrude and 22% in the blend, compared to 16% for the OIL crude alone. This finding is significant, considering the increased demand for air transportation fuel. Blending shows great economic promise. Using vacuum distillation, the product recovered is similar to 89% for the blend, whereas this recovery is only 76% for the OIL crude. The fractions obtained from blend distillation have characteristics that are similar to those of the petroleum crude. However, some additional treatment may need to be undertaken to reduce the stickiness and odor of the blended crude.
