Embodiment Construction

[0056] Below in conjunction with accompanying drawing, the present invention will be further described:

[0057] This crude oil pipeline transportation based on Analytical Hierarchy Process The consumption evaluation system analysis method includes the following steps:

[0058] Step 1: Establish a hierarchical structure model. Divide the system into several levels from top to bottom, each factor of the same level is subordinate to or has an influence on the factors of the upper level, and dominates the factors of the lower level or is affected by the factors of the lower level. In the energy consumption index system, the status of energy consumption is evaluated from four angles of physical object, intensity, efficiency, and index, among which G, M, and C represent indicators. The indicator system is divided into 3 layers. The first layer synthesizes the comprehensive impact of each sub-layer; the second layer includes four indicators that are the four main aspects of the e...

Abstract

The invention relates to a crude oil pipeline transportation exergy consumption evaluation system analysis method based on analytic hierarchy process. The analysis method comprises: first, exergy analysis of the process of crude oil pipeline transportation is carried out, crude oil pipeline exergy consumption evaluation system Hierarchical structure model is established according to the analysis index; according to crude oil pipeline exergy consumption evaluation system Hierarchical structure model, the judgment matrix of each index at different levels is constructed by 1 - 9 scale method, andthe weight of each index at different levels is calculated by root-square method according to the matrix of each level, and the eigenvector of the largest eigenvalue is normalized when being processed; consistency of judgment matrix is judged, if relevant indexes meet that requirement, the consistency of judgment matrix is accepted, and according to the index weight of each hierarchical structure, the influence degree of the low layer to the upper layer is obtained; 4. Combining the production data of the pipeline, the energy efficiency of the crude oil pipeline transportation process is evaluated; the energy consumption coefficient of pipeline crude oil is Calculated. The system of the invention judges the energy-saving potential and the improvement direction of the energy consumption.

Description

technical field [0001] The invention relates to the field of energy efficiency evaluation of crude oil pipelines, in particular to a crude oil pipeline transportation system based on analytic hierarchy process Analysis method of consumption evaluation system. Background technique [0002] Crude oil is generally transported by heating, which consumes a lot of fuel and is accompanied by heat loss and power loss, resulting in a huge amount of total energy consumption for pipeline transport of crude oil. The complex crude oil transportation process is affected by the temperature at the station and exit, the nature of the oil product, the external environmental conditions and the energy supply of each station. In general, researchers optimize certain technical and economic indicators by optimizing and adjusting the operation plan. Therefore, minimizing energy consumption is the ultimate goal of pipeline operation optimization research. After a series of theoretical and experim...
