Instructions for Use at Petroleum Refineries
Halfrid®neftekon Application instructions for Use at Petroleum Refineries
The present Application Instructions are developed for the use of quantum fuel activator Halfried®neftekon as a part of crude petroleum to increase gasoline and diesel oil cut during petroleum refining.
As for the method of application, Halfrid®neftekon belongs to the group of petroleum additives.
2. Composition and Operating Principle
Halfrid®neftekon is a stabilized solution of specific organic substance in the mixture of petroleum hydrocarbons with boiling limits from 185 to 310 °С. In appearance Halfrid ®neftekon resembles hydrocarbon fuel from pale‐ yellow to reddish colour with slight characteristic odor.
|Chemical element||Percentage by weight|
|Oxygen||no more than 0.3|
|Sulphur||no more than 0.1|
Halfrid®neftekon operating principle is based on the effect of quantum polyresonance activation (QPA),which is induced in petroleum products in their gas phase during petroleum refining and results in particular the ordering of vibrational‐rotational movement of incident reactants which leads to reduction of its entropy and heat‐absorption capacity. In activated petroleum resonance oscillation stimulation of hydrocarbon atomic groups of molecules occurs at different frequencies, which results in hydrocarbon chains break and, as a sequence, increase of light fractions yield (petroleum and diesel oil) during petroleum refining.
- increase of light fraction yield during petroleum fractionation up to 11%;
- increase of diesel oil cut up to 8%, increase of gasoline cut up to 5% during direct petroleum refining;
- decrease of bottoms to 17%;
- light fractions quality improvement (additional formation of isoparaffins and formation of aromatic compounds).
4. Method of Application and Dosage
Petroleum activation can be performed through adding activator:
- to drums and tank vessels during transportation;
- to petroleum depots during storage;
- by direct dosage to the petroleum delivery line in the fractioning column during petroleum refining.
4.а. Activation in the Storage Tank during Transportation and Storage
- It’s necessary to estimate the amount of activator essential for the activation of total petroleum tank volume (see “Table of dosage”);
- Add required amount of Halfrid®neftekon into the tank with crude petroleum;
- Activator dispersion in crude petroleum takes up to 5 minutes;
- In order to avoid the additional errors it’s recommended to use measuring tanks with not less than 2nd accuracy class for Halfrid®neftekon dosage.
4.б. Activation in the Petroleum Delivery Line to the Fractioning Column
- For activation a proportioning unit cut into the crude petroleum delivery line is used for continuous delivery of the activator;
- At first it’s recommended to estimate the approximate petroleum product content in the column. After that it’s necessary to calculate Halfrid®neftekon quantity for the activation of total petroleum column volume taking into account the volume of the petroleum with activator supplied into the system;
- After Halfrid®neftekon has been delivered for the activation of products in the column, activator dosage is performed only for crude petroleum activation continuously supplied for fractionation;
- In order to avoid additional errors it’s recommended to use batch meters with no more than 5% dosage error for Halfrid®neftekon dosage.
Halfrid®neftekon dosage for Petroleum Activation
|Activator (Halfrid®neftekon)||Crude petroleum (Litre)|
|0.1 ml (cm3)||2|
|1.0 ml (cm3)||20|
|2.0 ml (cm3)||40|
|10.0 ml (cm3)||200|
|100.0 ml (cm3)||2000|
|1000.0 ml (cm3)||20000|
|2000.0 ml (cm3)||40000|
Halfrid®neftekon standard volume/flow is defined on the basis of petroleum volume and equals to 1 ml of compound per 20 liters of crude petroleum and 1 liter of activator per 20000 liters of crude petroleum.
Note: it’s not recommended to make any pauses in petroleum activation because in this case the process adapted to the activated petroleum every time turns back to its initial state. Further increase of light fractions can be achieved only with continuous activated fuel use.
5. Cooperative Effects
Increase of distillation refractivity and decrease of its density can prove the development of chemical transformations of hydrocarbons (supposedly, low temperature cracking distillation, isomerizating and dehydrocyclization).
6. Safety Precautions
The safety precautions of Halfrid®neftekon use are the same as for the hydrocarbon fuel. Detailed safety instructions are presented in corresponding sections of Halfrid®neftekon Technical Specification.
7*. Testing Rules
When testing specific yield and qualitative composition of light fractions and bottoms during petroleum refining before and after activation are compared. The specific yield of different fractions is calculated according to the following formula:
Hsp. = m/М*100%
where Hsp. ‐ specific fraction yield [%],
m – distillation weight or fraction yield [t] or [t/hour],
М – total mass and consumption of crude petroleum [t] or [t/hour].
Average calculation (petroleum consumption, specific distillation yield, etc.) is often complicated because of simultaneous presence of significant errors and their components. For instance, to define specific light fraction yield it is necessary to measure crude petroleum consumption. Both values can be measured with a certain error and, according to the laws of mathematical statistics, the overall error is combined from the errors of both values, which results in greatly altered data with low integrity.
To increase the integrity of such measurements equal operation conditions are chosen when comparing specific yield of different fractions during petroleum refining before and after activation (the same crude petroleum party, the same equipment for crude petroleum refining, equal petroleum consumption and petroleum refining volume before and after activation). The integrity of calculations can be increased using mathematical treatment approach, for example, least squares method and graphic methods.
In this case the following approach is usually used:
A graph for the petroleum consumption “m” is built (or for the level of the suction tank) against certain fraction yield. If the specific fraction yield is approximately stable, then data points are drawn about a straight line, the canting angle of which to the axis of ordinates is numerically equal to the average specific petroleum product yield in unit fractions. For the right construction the method of least squares is usually used, which requires the sum of squares of remainders of test values and of the values calculated according to the received straight line formula, has to be minimal.
