摘要
川渝天然气化工以生产甲醇、合成氨、尿素等基础化学品为主,为了推进川渝天然气化工高质量可持续发展,对区域内企业进行了走访调研,并结合政策导向、国际国内形势分析了行业面临的机遇与挑战。研究结果表明:①国家加大天然气勘探开发投资力度,加快天然气产能建设步伐,整体资源供应量有所提升;与此同时,随着经济增长,国家、地方政策支持,区域内天然气消费趋势显著提升,为川渝天然气化工可持续发展提供了原料保障;②天然气原料路线和煤炭原料路线的化工企业之间的成本差距逐步缩小,天然气化工产业优化管理、提升技术,国际形势复杂多变等因素,为川渝天然气化工高质量发展提供了机遇;③我国气头化工占比小、话语权弱,新建、扩建化工项目受限,“采暖季”原料天然气供应紧张等因素使川渝天然气化工发展受限。结论认为:“十四五”期间,川渝天然气化工仍将保持高速发展态势。
The natural-gas chemical industry in Sichuan-Chongqing region focuses on the production of basic chemicals like methanol,synthetic ammonia and carbamide.To encourage it with the high-quality and sustainable development,some research visits were conducted in relevant enterprises inside this region.Moreover,opportunities and challenges for this in⁃dustry were discussed according to some analysis on policy orientation as well as domestic and international situations.Re⁃sults show that(i)the state invests more in natural-gas exploration and development and is stepping up the construction of natural-gas production capacity,causing an increase in resource supply.Meanwhile,the natural-gas consumption in Sich⁃uan-Chongqing region tends to rise evidently following the economic growth together with the support of national and local policies,which may provide guarantee of raw materials for the sustainably industrial development;(ii)the cost gap between natural gas-based and coal-based chemical enterprises is narrowing.In the natural-gas chemical industry,management is optimizing and technologies are improving in addition to complex and ever-changing international situations,which may of⁃fer opportunities to this industry with the high-quality development in the region;and(iii)the natural gas-based chemical industry in China only accounts for a smaller share and weaker discourse power of the whole chemical industry,new and expanded chemical projects are limited,and raw gas is short supply in heating seasons,which may also restrict its industri⁃al development.It is concluded that the natural-gas chemical industry in Sichuan-Chongqing region will hold a high growth rate in the 14th Five-Year Plan period.
