Description

Статья. Опубликована в журнале Chemical Engineering Transactions. — 2014. — Vol. — 39 — P. 169– 174Hydrotreating section and catalytic reforming section of catalytic reforming unit L-35-11/600 were examined in this paper. This unit was designed for processing large fraction of naphtha by catalytic reforming in order to obtain components of gasoline with an octane number 78-85 points. Pinch diagnostics for these sections was carried out. Comparative economic analysis of their effectiveness after the proposed retrofit was performed for each section separately and for the total their flowsheet. The implementation of the Pinch Method for hydrotreating section will reduce energy intensity by 2.2 MW. Energy consumption for catalytic reforming section reduced by 6.4 MW. Energy consumption for joint integration of hydrotreating section and catalytic reforming section reduced by 11.4 MW. Therefore, it was concluded that Pinch design for these sections of catalytic reforming unit L-35-11/600 is most advisable to carry out for the two sections together.
