Analysis and design of an ideal gas distribution system

Abstract

Exploration, development and production activities for natural gas are technology-driven. These difficult and complex activities will not bring economic prosperity of the country unless the gas is properly utilh,ed. Gas distribution plays a pivotal role in appropriate usc of natural gas. It is the vital interface between the industry and the end users. Revenue is brought in by the distribution companies. So for a healthy business, it is imperative that the distribution system runs at the highest efficiency. Performance of all the distribution companies in Bangladesh is ruined by a phenomenon called 'System loss', It acoounts for 8% of the total gas. Apart from very little system requirement of gas (less than 2%) the rest of it is stolen. Technical and administrative flaws in system design, along with improper and old equipment use worsens the problem. Before embarking new network expaw;iolL,identification of the existing problems are very important. Titas Gas Transmission and Distribution Company, which is the largest with highest system Joss is chosen for the case study. Identification of thc drawbacks in the existing distribution system, suggestions for development of an ideal distribution system and meaningful evaluation of the suggested system are the main objectives of this study. Financial and economic evaluation of the suggested distribution system is mainly conducted to attract private entrepreneurs for investment in the gas sector. Positive refonns both technical and administrative will enhance that possibility even further. Recommendations of these changes are suggested at the end of this study.
