Reduction of exhaust gases temperature: our fuel oil emulsion decreases engines heat load.

✓ decrease of the heat load on the equipment;
✓ an increase of intervals between maintenance;
✓ therefore equipment repair cost savings.

Fine preparation of stable emulsion. Our equipment allows to produce an emulsion with 100% of water droplets size in nanometres. The average globule size is 30 nanometers.

Our emulsion does not exfoliate already for more than seven years!

Savings

Excerpt from the protocol of the specific consumption records.

Following the tests and the experiments that were carried out at Atlantic Island Electricity on the days 11/11/2016, 14/12/2016 and 20/01/2016, it was asked from me to analyze the data and to access the concordance between the several parameters thatt were used to measure the success of the tests. In previous conversations, it was agreed between the parties that the best way to evaluate the success of the procedures would be the measurement of the specific consumption and the control of the organic compounds present in the exhaust gases (more specifically, the Total Volatile Organic Compounds TVOC’s and the Total Non-Methane Hydrocarbons TNMHC’s). The reason for that is related with the fact that AIE’s engines are not prepared to be used as a lab test, since they are connected in a grid with the local electrical network and there are too many variables involved. The lack of sensitivity to small consumption changes need to be overcome by using independent parameters. Since the objective of the tests is the reduction of the fuel consumption and the way to achieve it is to produce an emulsion with water, the only way for it to work is to increase the engine combustion efficiency and increase the fuel oxidation during the residence time. This technology proposes to do that by reducing the fuel droplet sites and thus increasing the transfer area between the fuel (the reductant) and the oxidant. As it is well known, the most advanced combustion theoretical models establish the relation between the contact surface area and the efficiency of the process, which means the proposed model does not contradict the theoretical knowledge on the field. The results observed in the exhaust gases analysis (Madebiotech’s report) show that the concentration of TNMHC passed from 171.4 mg/Niii3 (without the tested system 11/11/2016) to 44.5 mme3 (with the tested system 20/01/2017). Taking into account the fact that the legislation establishes the limit of 50 mg/Nm’ for the TNMHC concentration, this reduction of 74% in the emissions, together with the reduction observed in the specific consumption, it can be stated that, if these results are reproduced, the tested technology is indeed an added value both in terms of economical rationality and environmental performance. The only thing I cannot analyze currently is the long-term effect of the technology on the engines and the associated maintenance costs.

To calculate the savings, is used the minimum consumption of diesel engine when working on heavy fuel oil – 206.20 g/kWh.
Ratio of fuel oil density – 0.92118.

Additional positive economic effect from the use of our equipment

A significant reduction in harmful gas emissions that could potentially bring cost savings on environmental charges both direct and aimed for purchase of more advanced equipment allowing to reduce such emissions.

As well as a potential increase in the period between routine maintenance and overhaul of engines because of the more benign modes of the equipment running on the emulsion.
