Accidents involving rotating equipment in chemical, petrochemical, petroleum, and gas plants can result in damage to other process equipment and catalysts along with lost production. Conversely, process upsets, process instrumentation failure, or failures of other process equipment can result in damage to rotating equipment. An effective rotating equipment loss prevention program will be an int...

In this study, nitrobenzene in water and ice samples collected from the Songhua River after the explosion of a petrochemical plant was determined by GC/MS. The results showed that nitrobenzene was detected in most of the water and ice samples taken from the Songhua River. However, the concentration of nitrobenzene in all water and ice samples was from 0 to 0.65 microg L(-1); this range was suff...

the establishment of good process safety management (psm) is widely considered as the most effective means of improving safety levels in process industries. this study was conducted to evaluate the feasibility of establishing and implementing psm requirements based on occupational health and safety assessment series 18001 standards (ohsas 18001) and health, safety and environment management sys...

Purpose The paper discusses the new concept of ‘Multinational Investment Projects’ (MIPs) and its application in the context of international business operations in China. The petrochemical industry in China is used as the industrial context in which we investigate the interplay between the Chinese government, which encourages growth and investment activities in the sector, and the multinationa...

the petrochemical industry is the most important and most widely active industries in the country. due to the variety and complexity of industrial products, it also produces a wild range of pollutants. mercury waste disposal from chlor-alkali units is one of the fundamental problems of this industry. various studies have shown that phytoremediation system for removal of mercury from aqueous sol...

As industrial facilities, petrochemical plants require prompt investigation, diagnosis, and recovery in the event of fire damage associated with disasters accidents. Due to characteristics plants, which are mostly composed steel structures fire-resistant coating materials, materials first be damaged. Accordingly, this study, were analyzed experimentally, verifying possibility estimating heating...

Theactive sludge process is one of the most-used techniques for biodegradation organic compounds present in effluents from an assortment wastewaters. This study investigated bacterial community structure a petroleum industry’s activated and its physical chemical parameters using high-throughput sequencing. Samples were collected over year: autumn 2015 (C1), winter (C2), spring (C3), summer 2016...

The occupational health program of a large oil refinery and petrochemical plant incorporates features which aid in the detection of pulmonary tuberculosis. The periodic examination system which includes a routine chest roentgenogram and which is conducted on all plant employees at 12-24 month intervals would be expected to discover asymptomatic cases. In addition, other cases might be found whe...

The management of a population of centrifugal pumps in the petrochemical industry can be daunting. A popular method for strategically optimizing the maintenance and operation of these centrifugal pumps is to measure the reliability of the whole pump population in terms of Mean-Time-Between-Failures (MTBF). Too often MTBF improvement becomes the focus rather than a means of supporting the actual...
