ISOCMIX PROJECT CONCEPT
This Project will design, finance, build and operate infrastructure to produce a proprietary premix fuel, ISOCMIX®, primarily for 2-stroke outboard motor engines utilising state of the art Isomerisation Technology.
Once-Through
Isomerization
In a once-through isomerization process, the
feedstock is mixed with hydrogen make-up gas. The mixture is then heated and
enters a first reactor where benzene saturation and partial isomerization take
place.
The gas-product mixture exits the 1st
reactor, is cooled and then fed to a 2nd reactor to complete the isomerization
reaction at chemical equilibrium. The product mixture from the 2nd reactor is
cooled and fed to a gas separator, where the mixture is separated from the
excess hydrogen gas. Excess hydrogen is combined with make-up hydrogen and fed
through the recycle dryers for blending with feed.
Saturated isomerate from the separator is heated
and fed to the stabilizer. The stabilizer’s overhead vapours are cooled and fed
to a reflux drum. Liquid hydrocarbons from the reflux are returned to the
stabilizer as reflux, while uncondensed light hydrocarbons are separated and
sent to the off-gas system. The bottom product or isomerate is cooled and sent
to gasoline blending to produce Premix Fuel RON 83.

Feedstock
Pentanes and Condensate Feedstock from the GNGC – Atuabo Gas Processing Plant will be utilised in the production of ISOCMIX®. The production facility will meet the required premix fuel specifications of the Ghana Standards Authority and a high level of safety and prudent environmental considerations will be embedded in the design. The condensate feed to the plant site will be C4+.
Storage tanks for the safe reception and
efficient storage of the feedstock and product shall be designed and constructed taking into consideration
overall facility fire safety considerations and the minimum number of days for
stock holding. It shall be complete for measurement devices for transmission of
tank levels to a central control room and remotely operated valves. It will
have standard loading and metering facilities.
This will be a laboratory fitted with state
of the art analysis and testing equipment for quality assurance process
implementation. Environmental compliance analysis will also be conducted in the
laboratory.
