Technology Engineering Holding PETON has successfully completed project “Modeling and calculation of extractive distillation and afterfractionating (EDAF) package unit of columns K-201 and K-202 when operating with the application of new feed. Unit 35-8-300B, EDAF PU of LUKOIL-Permnefteorgsintez, LLC” for LUKOIL-Engineering Skills and Expertise.
The works began in December 2022 and lasted until February 2023.
As part of the project, Peton performed the following scope of work:
1) Collection of input data.
2) Performance of experimental-industrial test run in EDAF PU 35-8-300B at LUKOIL-Permnefteorgsintez when process and analytical data on PU operation were collected.
3) Development of models for the operation of the EDAF PU for current mode and for the potential one (change in PU feed).
4) Performance of checking calculations for the main equipment of the EDAF PU.
5) Preparation of final report with the statement on the need to revamp the equipment and change the standards of the process mode.
The complexity of the works was that the PU uses a Western-made extractant, the composition of which was unknown. In the course of the works, PETON specialists performed works on the selection of physical and chemical properties of the extractant in a specialized software.
Integrated approach to the implementation of the project, including the development of the procedure and the performance of the experimental-industrial test, allows to create the process model of the subject of research as accurately as possible. The company is well experienced in similar works: previously, such works had been performed in CDU/VDU units at Novoshakhtinsk Refinery and in various units at refineries in the Republic of Bashkortostan.
