Abstract

The invention discloses a continuous on-line blending method and device for a semi-finished product. The conventional oil tank blending process is abandoned, and a new method is found, the conventional equipment such as the pump, the flow control regulating valve, the flowmeter and the process pipe and other devices are used, meanwhile, the original technological process is improved slightly, a cross-line and a corresponding gate valve are added between two kinds of semi-finished oil of a first vacuum side stream and a second vacuum side stream, an on-line blending process is opened up, and a group of on-line mixers is added behind the mixing point of the two semi-finished oils, so that the two semi-finished oils are uniformly and fully mixed, and the product quality is improved to meet the requirements of users to product quality. Therefore, the problems of large occupied area and multiple middle oil tanks of the oil tank blending manner as well as large equipment input of the tank area pipeline blending manner are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum smelting, in particular to a method and device for continuous on-line blending of semi-finished products. Background technique [0002] At present, the petroleum refining industry occupies an important position in the national economy and is one of the pillar industries. After years of development, the petroleum refining industry is characterized by large scale, modern technology and diversified varieties. Due to comprehensive consideration of technology and economy, coupled with the limitations of the processing technology of refinery units, the performance of primary product oil (semi-finished oil) produced by each refinery unit generally cannot meet the requirements of various oil quality. In terms of processing technology, oil blending is the last process before petroleum products leave the factory in oil refineries. The so-called oil blending is to use a certain proportion of two or more p...
