Sažetak
Process plants in the oil refining industry are designed with a useful life of 15 years. Most users of these types of plants try to extend their exploitation time to over 20 years. This can be accomplished through investment maintenance, which includes modifications or changes of design solutions based on rationalization of production, or by modifying roles of particular elements in the overall process. A great number of modern lubricants is produced through different oil refining procedures and by further processing products of the oil refining process, mainly paraffin based. Successful utilization of the oil refining technology aims our activities to production optimization and/or modifying roles of some plant components, while accepting some new techniques of plant operation. This paper will present research results from oil refining plants for hydrocracking and production of the basic oil distillate that includes the VPS plant into the production process. Investment maintenance, with modifying certain design parameters of the hydrocracking process and including the VPS plant, will lead to selective conversion of the entering charge instead of the total conversion. Referring to that point, an analysis was performed and comparison made between the original design defined data and the data obtained through laboratory tests for hydrocracking and production of the basic oil distillate. Based on this analysis, it can be concluded that there are still some possibilities in the production of fractionator for hydrocracking. That leads to a need for checking and calculating the possibility of controlled modification of certain designed process parameters. This would be done through determining the phase makeup of the process flow at the top and bottom of the debutanizator and of the products on the top of the condenser outlet. It is also important to analyze the influence of these modifications on the process furnace operation.
