General information on the "PPG-technology" used in installations series "NP-IDP"
The unit is designed for processing the distillation residue (oil) produced by devices such as the AT series "NP-MV", based on "PPG - technology," which allows you to bring the depth of processing of HC to 70-80%.
The essence of "PPG - Technology" is to conduct thermolysis raw materials using a special activating effects as technological methods, enabling a selective effect on the individual groups of hydrocarbons under thermolysis. Impacts are based on the submission to the pre-reaction zone of the activating gas recycle stream certain fractions of hydrocarbons and recycle water-soluble metal salts, which makes changes to the dispersion stability of liquid hydrocarbons, and greatly intensifies the process of destruction of the heavy fractions at temperatures too low to intensive processes of polycondensation ( coking).
These reactions occur at relatively low temperatures - 370-450 ° C. Are most easily cracked paraffinic hydrocarbons, and the most difficult - aromatic hydrocarbons. Naphthenic hydrocarbons are intermediate.
In addition to reducing the temperature degradation processes of heavy hydrocarbons, gas bubbles intensify the evaporation of light fractions, effectively taking them out of the reaction zone, and the recycle of heavy metal salts factions, working as catalysts give a general elevation of products allow them to get much closer in quality to the modern requirements of a motor fuel. Also, there is a reduction of viscosity, sulfur and nitrogen compounds, removal of heavy metals.
Thus, the use of the described process can significantly reduce the cracking temperature - up to 450 ° C and below, to avoid unwanted coking equipment, and the process be carried out at low pressure.
Thermomechanical effects on raw material applied in the new technology, keeps aggregate stability of the reaction mixture, even at high concentrations of asphaltenes. This allows, on the one hand, a large degree of conversion of heavy hydrocarbons into light oil, on the other hand, get a residual product concentrated colloidal solution of resins and asphaltenes - the ideal basis for the production of non-oxidized bitumen of different brands.
Material balance "PPG - Technology" *
* Experts' AZSNEFTEBAZSTROY "This process is constantly reviewed and improved, which allows to obtain guaranteed results to the output of light hydrocarbons.
Table 3 shows the results of the processing of straight oil with Urengoy field. It is shown that by varying the parameters of activation, you can significantly change the output of refined products, which are light and gas oil fractions, with the balance of fuel oil is obtained. These data are the results of working out a pilot plant with a capacity of 2 tons per hour of raw material at the operating temperature of 390 °C
For an example, the calculation made for one of the customers, increase the yield of light oil in the application of PPG technology in conjunction with the installation of the AT. Depth of processing is taken at the level of 70-80%
Trade balance of the plant capacity of 100 thousand tons per year (ThTpY).
At the rate it is clear that the yield of light hydrocarbons, in the application, "PPG-technology" increases by 1.6 times, with an increase in the cost of installation of 1.46 times.

MINI GAS PROCESSING PLANTS
Research and Development Centre named after Nikola Tesla, Ioshkar Ola; AZSNEFTEBASTROI, Moscow; and New Petroleum Technologies LLC, Stavropol offer mini Gas Processing Plants (MGPPs).
In this presentation, we provide a complex with improved technologies that fundamentally differ from the existing ones. This enables to tackle different tasks relating to the processing of hydrocarbons. The unit can have different throughput capacity based on customer’s wish.
A MGPP is intended for the processing of associated petroleum gases (APG) to liquid hydrocarbons. The process is based on the Lebedev’s synthesis conversion that takes place in the SHF fields. The feedstock is water + associated petroleum gas (APG); intermediate products are water + acetylene, the output product is a mixture of C1-C5 alcohols and C5-C12 hydrocarbons.
The alkylation reaction that has been used in the chemical and hydrocarbon process industries is the essence of the process. The reaction proceeds using catalysts at temperatures of 530-560оC and at the pressure of 10 atm. The main device is a tube reactor (with a diameter of 200-250 mm and a length of 1.5-2.5 m). At least two of these reactors will be installed to provide regeneration of the catalyst. A bigger output of heavy hydrocarbons can be achieved if the number of the reactors is increased to 4 or 6.
The received mixture of hydrocarbons and alcohols is fed to the oil treatment unit while a part of the alcohols (methanol-butanol) is dissolved in the stratum water and together with the latter it is pumped into the productive strata. The presence of the alcohols in the water must improve the wash-off properties and increase the oil displacement efficiency; however, this aspect has not been considered yet. The residual alcohols and liquid hydrocarbons will be dissolved in the oil and realized together with the latter.
Advantages of the offered MGPPs are as follows:
When the microwave processing rate of a chemical reaction increases a hundred times or more, the reaction time is reduced by the same amount. Plants are compact, less metal content of equipment, respectively, significantly reduced cost.
These technologies provide products complying with Euro-3, 4.
Three column of the 25 tons tons per year
Five column of the 25 Comrades per year
Our developments are based both on the traditional oil refinery practices and the experience gained in other fields.
The design based on all the foregoing enables to more accurately understand, model and perform technological processes. These solutions are protected by the patents of the Russian Federation; and the process of obtaining foreign patents is in progress.
Thus, AZSNEFTEBAZSTROY is ready to act as an engineering,
company for the construction of oil refineries, consolidate and successfully implement the potential of domestic and foreign developments in the field of oil refinery
