Abstract

The invention provides a system and method for producing refined heavy naphtha. The system comprises a raw material pretreatment system, a hydrogenation reaction system and a stripping tower which are connected in sequence, a refined condensate oil outlet at the bottom of the stripping tower is connected with a feed inlet of a debutanizer, an oil phase outlet at the bottom of the debutanizer is connected with an inlet of a light naphtha separation tower, and a heavy component outlet of the light naphtha separation tower is connected with a material inlet of the heavy naphtha separation tower. The system for producing refined heavy naphtha solves the problems of long route and high technical difficulty of the traditional process, reduces the processing energy consumption and processing loss of the whole system, and improves the economic benefit.

Description

technical field [0001] The invention relates to the technical field of petroleum processing, in particular to a system and method for producing refined heavy naphtha. Background technique [0002] There are two main methods for the production of existing refined heavy naphtha: one is straight-run naphtha produced by atmospheric and vacuum devices using crude oil as raw material, and it is combined with a small amount of diesel hydrogenation / jet fuel hydrogenation refined naphtha The raw materials are pumped from the mixed naphtha to the feed buffer tank of the reforming pre-hydrogenation unit, and first undergo a pre-hydrogenation reaction to remove non-metallic impurities such as sulfur, nitrogen, oxygen, and metals such as arsenic, copper, and lead in the raw oil. Impurities, at the same time, hydrosaturate the olefins in the feedstock oil. After the oil is produced, the fractionation part adopts a double-tower process, in which the stripper is used to dehydrate, H2S, NH3...
