Abstract In order to establish a comprehensive exergy consumption evaluation system for crude oil pipeline transportation system, this paper proposed the definition and calculation method of unavoidable exergy loss based on the exergy analysis method and basic process of pipeline transportation. Then combined with the exergy flow classification, the exergy consumption index set was established and selected with correlation coefficient method. Furthermore, the exergy consumption evaluation index system was established including four hierarchies of object, intensity, efficiency and target using analytic hierarchy process and the weight of each part was calculated. Finally by means of all the exergy consumption indexes, the status of using energy was analyzed and evaluated. The analysis results showed that optimizing the transportation amount and temperature, energy efficiency could be improved. The evaluation system of exergy consumption established in this paper could improve operation efficiency and reduce energy consumption.

The authors of the article have developed the computer application allows to determine the value of the friction coefficient λ and anti-turbulent additives efficiency with a high degree of accuracy. The program can be used in the calculations and design of oil pipelines. The paper presents experimental studies of the effect anti-turbulent additives on the magnitude of pressure losses during fluid movement through pipes. The data gained by the developed computer program has been proved by the data of practical application of additives in the real oil pipeline transportation system called Eastern Siberia-Pacific Ocean oil pipeline.

A concrete placing boom is the final element of concrete mixture pipeline transportation system. It is designed to deliver the concrete mixture for discharging where and when required, therefore, similar to cranes, it must be equipped with at least two mechanisms: boom extension and rotation. The mechanisms can be both manually and hydraulically actuated, hence, booms are differentiated between mechanical (manually controlled) and hydraulically or electrically controlled. This article aims at describing the areas for using various categories of concrete placing booms.

Product Storage

Above ground petroleum product storage tanks are tanks or other containers that are above ground, partially buried, bunkered, or in a subterranean vault. These are built to store petroleum product for pipeline system, oilfield and refinery. Tank fires are one of the most terrible accidents in oil pipeline transportation stations. Tank fires pose a significant hazard to people, buildings, process piping, the environment and other facilities as a result of thermal radiation exposure. It is necessary and meaningful to study the distribution of the thermal radiation of a tank fire for emergency response, prevention and reducing loss. To analyze potential tank fire incidents at a pipeline station, a three-dimensional station model was built using a computational fluid dynamics (Abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows) software package to evaluate the thermal radiation distribution under different conditions. Numerical simulations were carried out for a total of six simulation scenarios to analyze 3 types of potential fires for 2 different liquid products (gasoline and diesel). The three kinds of fires that were modeled included: 1) disk pool fire on top of the tank; 2) ring pool fire on the top of a tank; and 3) pool fire in a dike. The simulation evaluates the effect of the thermal radiation on facilities and people. The simulation results show that the water cooling system is effective at decreasing the magnitude of thermal radiation exposure and as a result is effective at protecting nearby tanks and facilities. Without water protection, the disk fire or ring fire can destroy or damage nearby structures significantly. The results of the simulation also show that the dike pool fire can have a catastrophic consequence to nearby facilities. Further the analysis showed that environmental wind does not change the thermal radiation distribution significantly. The results of the simulation point out countermeasure activities to enhance fire prevention at oil pipeline transportation stations in a scientific way.
