In a petroleum refinery the hydrocarbon emissions which are mostly fugitive in nature are emitted from process, offsites and periodic accidental releases such as: materials storage & handling, process, equipment leaks, solvent evaporation, combustion sources, waste treatment etc. In India, the monitoring of such emissions in a refinery are limited as also the standards are not set for its limit in ambient air. Hence there is an urgent need for generating a database for such emissions. Recently in India, MoEF/CPCB has set some guidelines under CREP rules for monitoring such emissions in a refinery. A detailed monitoring of the hydrocarbon emissions from different sources in a typical 10.5 MMTPA Indian refinery is undertaken during 1999-2001 and the results are presented. It is observed that the storage tank emissions alongwith process leaks form the major contributor towards fugitive hydrocarbon emissions.
在石油炼制厂中，大部分具有逸散性的碳氢化合物排放源自工艺过程、厂外区域以及周期性意外排放，例如：物料储存与装卸、工艺过程、设备泄漏、溶剂蒸发、燃烧源、废物处理等。在印度，炼油厂此类排放的监测工作有限，且环境空气中此类排放的限值标准也未制定。因此，迫切需要建立此类排放的数据库。最近在印度，环境与森林部/中央污染控制委员会已根据《持续环境改善计划》规则制定了一些准则，用于监测炼油厂中的此类排放。1999 - 2001年期间，对一家典型的1050万吨/年印度炼油厂不同来源的碳氢化合物排放进行了详细监测，并给出了结果。据观察，储罐排放以及工艺泄漏是逸散性碳氢化合物排放的主要来源。
