petrochemical industries are potentially capable of impacts on environment due to the essence of the activities and producing waste water, pollutant emissions and hazardous wastes. this case study has considered the environmental adverse impacts of petrochemical industries on existing habitats in mahshahr economic special zone with respect to the regional significant biological diversity and ec...

There were various problems in the determination of oil acid value of the national standard method, and this paper developed a low cost, simple and effective way to determine the acid value of oil and grease. Furthermore, the esterification of high acid Euphorbia lathyris L. oil (ELO) with methanol could be efficiently catalyzed by hydrochloric acid to produce biodiesel, and the influencing fac...

This dissertation aims to develop new condition-based maintenance (CBM) tools for increasing performance of Apache helicopter drivetrain gearboxes, through lubrication and signal analysis. An extensive consumer of CBM is the Apache helicopter that involves testing critical components to demonstrate reliability and performance, measured through data-driven condition indicators (CIs). These indic...

The evolution of the film thickness in a grease lubricated rolling bearings is given by continuous process loss and replenishment oil track. It believed that long run, maintained bleeding from reservoirs. capabilities thus have an impact on and/or bearing life. ability to bleed changes during operation due mechanical ageing, which affects fiber structure grease. In this study lubricating consid...

This study was undertaken to evaluate a novel aerobic wastewater treatment model for the remediation of refinery effluents and to assess the removal efficiency of Bulkholderia cepacia strain AJI and Corynebacterium kutscheri strain AJ2 to clean oil waste from petrochemical company. Wastewater quality parameters including pH, BOD5, COD, TDS, OIL & GREASE, PHENOL concentration, TPH and THC were m...

Solid deposition, such as the formation of ice on outdoor facilities, the deposition of scale in water reservoirs, the sedimentation of fat, oil, and grease (FOG) in sewer systems, and the precipitation of wax in petroleum pipelines, cause a serious waste of resources and irreversible environmental pollution. Inspired by fish and pitcher plants, we present a self-replenishable organogel materia...
