P43 SUBMERGED ROTARY JET TECHNOLOGY
REPORT ON GASOLINE BLENDING TRIAL
This report shows that the time required to blend to a constant S.G. within 0.003 can be
reduced from approximately 66 hours utilising side entry propeller mixers to
approximately 6 hours utilising the Progressive P43 machine.
It is further recommended and suggested that the blending time can be improved to less
than one hour by adding correcting hydrocarbon through the P43 machine.
1) INTRODUCTION
The Progressive P43 machine is motivated by a flow of hydrocarbon pumped
through the machine, a proportion of which drives an impeller. The impeller rotation is
reduced through a series of gears, the final drive of which transmits a slow rotation to the
nozzle body resulting in a jet of hydrocarbon sweeping the base of the tank every 90
minutes.
Early dye tests show that a single P43 machine is capable of effectively mixing a 46 metre
diameter tank filled to 7 metres with water, in only 30 minutes.
2) OBJECTIVE
The problems associated with rapid and efficient hydrocarbon blending are well
documented.
A major UK Oil Refinery has an export customer for gasoline which invariably requires
correction and blending of their standard product.
Using the existing side entry propeller mixer system, the blending time was typically fifty
hours.
The objectives of the trial were to reduce the blending time thereby improving throughput
and minimising costly delays.
3) METHODS
3.1 Refinery drain tank to facilitate manway removal.
3.2 Progressive mobilise one diesel driven pump unit plus one shell mount P43 machine
complete with specially designed manway cover.
3.3 Progressive install P43 machine and connect up with 8 inch cargo hoses to the mobile
unit.
3.4 Refinery fill tank with relevant quantities of gasoline (for trial purposes, the quantities
and qualities of gasoline were chosen to be a 'difficult' correction).

3.5 Progressive circulate tank contents through the P43 machine while refinery personnel
sample and analyse at hourly intervals.
3.6 After eight hours running time, Progressive shut down pumps and disconnect from P43
machines.
3.7 Tank drained, P43 removed.

Hourly samples were taken from Top (1 metre from roof) Middle (9.5 metre from floor)
and Bottom (1 metre from floor).
Results are graphically represented and show that complete homogenisation was effected
to 0.003 S.G. in six and one half hours.
For comparison purposes, this trial was repeated under the same conditions utilising the
existing two Kilowatt side entry propeller mixers. Homogenisation was effected to 0.003
S.G. in sixty six hours.
