| Along with LNG used in Shenzhen from 2006, and the west-east gas transmission project will arrive in Shenzhen soon, the gas format will have great changes in Shenzhen. Although the use of natural gas range increased, the liquefied petroleum gas (LPG) will exist for a long time in the city gas. In order to accurately predict the future development direction, guide the planning layout of the bottled LPG, project team conducted the research of bottled liquefied petroleum gas supply in Shenzhen. During the research team consulted the relative literatures and visited LPG enterprise, design institute,refer to the requirements of UPDIS, our main research content as follows:(1) Prediction of gas consumption. Used different methods to calculate gas consumption, after contrast we choosed mixed forecasted model which was predicted resident, commercial, industial separately,.Refered to Shenzhen examples, we choosed Auto Regression model, Inverse model and Growth model, and the results was ideal.(2) Research of supply site. According to research different supply modes and reference related experience, we determined the supply of households, turnover days and minimum area of various levels. From the study results, the minimum area of I lever (>10~≤20m~3) was 600 m~2,â… level (>6~≤10m~3) was 435 m~2,â…¡level (>3~≤6m~3) was 270 m~2,â…¡level (>1~≤3m~3) was 225 m~2.(3) Research of delivery and operation modes. According to the present situation, we proposed several delivery and operation modes. In the practical applications we should adjust measures to the local conditions, in order to achieve customer satisfaction and enterprise benefit.This essay had suggtestions to the planning layout. The research methods and results have realistic meaning and theoretical significance, which can be uesd to the LPG resesach in other cities. |
