| Popis: | The relevance of the research is caused by the need of catalytic reforming modernization by selecting and varying feed on the basis of an existing enterprise, as well as at the stage of its design. The main aim of the research is to analyze the influence of raw materials from a gas condensate field on the qualitative and quantitative characteristics of the product. Objects: feed from three gas condensate reservoirs in Western and Eastern Siberia. Methods: determination of individual and group hydrocarbon composition by capillary gas chromatography method; mathematical modeling to study the impact of feed varying. Results. A mathematical model of semi-regenerative catalytic reforming was developed. The feed composition impact on the reformate yield and quality was studied using the mathematical model. The feed used is degassed condensate from three different gas condensate fields in Western and Eastern Siberia. The degassed condensate was obtained by standard separation in the research laboratory «GasInformPlast». The paper introduces the index of raw materials, indicating the predominance of a certain hydrocarbon group in the compositions of three degassed condensates. It was revealed that use of the feed from gas condensate fields with a minimum content of paraffin hydrocarbons and a high value of naphthenic and aromatic hydrocarbons leads to increase in the yield of aromatic hydrocarbons by 20 % wt.; increase in reformate yield by 3 % wt.; increase in octane number by 7–8 points; increased coking by 0,5 % wt. The change in the composition of gasoline fractions during gas condensate field operation for five years is analyzed using the mathematical model. It was established that increase in the life of the deposit has negative effect on the catalytic reforming system due to the increase in aromatic compounds in its composition. |
