1 前言 上海是中国最早拥有人工煤气设施的城市,自1865年以来,人工煤气事业不断发展。随着东海天然气工程的建成投产,上海开始进入天然气时代。鉴于环境保护、整体布局、运输条件等综合因素,上海市将不再建造新的人工煤气厂。东海天然气供气能力为120万m~3/d,主要供应浦东地区用户用气,除替代原人工煤气用户外,许多用户为新发展用户。根据规划,后续天然气工程的供气时间预计为2003年,因此对此前人工煤气的供应状况进行分析,并提出相应对策和建议,对于确保城市燃气供需平衡有重要意义。
1 Foreword Shanghai is the first city in China to have artificial gas facilities. Since 1865, the artificial gas business has continued to develop. With the completion and production of the East China Sea natural gas project, Shanghai began to enter the natural gas era. Due to comprehensive factors such as environmental protection, overall layout and transportation conditions, Shanghai will no longer build a new artificial gas plant. The Donghai natural gas supply capacity is 1.2 million m3/d, which is mainly used by users in the Pudong region. In addition to replacing the original artificial gas users, many users are new development users. According to the plan, the gas supply time for the follow-up natural gas project is expected to be in 2003. Therefore, the analysis of the supply conditions of the artificial gas before this and the corresponding countermeasures and suggestions are of great importance to ensure the balance between supply and demand of urban gas.
