A multistream plant has a definite advantage of achieving an overall lesser downtime as compared to a single-stream plant based on Partial Oxidation because the outage of individual stream does not necessarily put the plant out of operation. But the safety considerations in the design, operation and maintenance of a multistream plant should be all the more elaborate and well defined. Usually the multistreams have common utility sources and a number of interconnections provided for the side streams. The present paper is a case study of an incident that occurred in the Ammonia Plant when the maintenance work was in progress in one stream and the other two were under operation. 相似文献

In September, 1985, Union Carbide established a new, comprehensive corporate-level audit program. The development of this program included careful consideration and incorporation of current and emerging practices in the field of health, safety, product responsibility and environmental auditing. Union Carbide's efforts in this area are but one element of its overall health, safety and environmental management system. 相似文献

海外石油企业与国内企业在HSE(健康、安全、环保)管理方面存在着很多差异。这些差异既体现在理念上,也体现在制度上。其中,深层次的差别体现在综合管理上,差别的根源是制度管人还是人管人,主要体现在管理体制和机制上。概括地说,海外石油企业的HSE管理胜在强烈的责任心,规范的机制体制和制度,严格的管理以及先进科学的方法,外在因素是所在国政府对石油企业的严格监管。 相似文献

With rising environmental concerns from consumers and stakeholder groups, environmental management has become an important responsibility for today's fashion and textiles manufacturers. The production of fashion and textiles related products often requires high levels of energy and water consumption, and emits large quantities of pollutants to the environment. Therefore, the adoption of environmental management systems (EMSs) is important and could have a significant impact on these firms' operational performance. This study presents empirical evidence on the performance impact of EMS adoption in the fashion and textiles related industries (FTIs). Although EMSs have emerged as a passport to business in the FTIs, their actual impacts on firms' financial performance have not been explored. We reveal that the adoption of ISO 14000, the most popular EMS, improves manufacturers' profitability in the FTIs over a three-year period as measured by return-on-assets (ROA). Based on our sample, we find that profitability improvement started during the implementation stage and continued at least one year after the firm obtained ISO 14000 certification. We also find that profitability improvement is mainly due to improvement in cost efficiency, measured by return-on-sales (ROS). Specifically, certified firms improved up to 2.9% in ROA and 3.3% in ROS over the three-year period since they implemented ISO 14000. We conclude that there is a positive impact of EMS adoption on firms' financial performance in the FTIs. 相似文献
