The growing global demand for sustainable technologies that improves the efficiency of petrochemical processes in the oil industry has driven advances in petroleum biotechnology in recent years. Petroleum industry uses substantial amounts of petrochemical-based synthetic surfactants in its activities as mobilizing agents to increase the availability or recovery of hydrocarbons as well as many o...

The foam that occurs in the process can cause problems with effectiveness of or quality final product. economic consequences uncontrolled foaming be very significant and serious losses require expensive operating changes. Foaming just as treating other types problems, such corrosion, fouling, emulsion. Indonesia is known largest producer palm oil, so it has potential a downstream oil derivative...

In this work we investigated the structure of the iron-stimulated surface tension reducing substances produced by P. citronellolis 222A isolated from a 17-years old landfarming used for sludge treatment in petrochemical industries and oil refinery. Its mass spectrum differs from P. aeruginosa spectrum, indicating that the surface tension reducing substances produced by P. citronellolis can be a...

this survey aimed to evaluate the level of lead (pb) pollution in cattle in the vicinity of the shiraz oil and petrochemical industries using hair samples. dairy farms located within 10 km of the shiraz oil and petrochemical industries were identified and divided into four groups. farms that were located in the radial zones of 0.5-1.5 km, 1.5-5 km, 5-7 km, 7-10.5 km were considered as groups a,...

Buried or inaccessible piping systems within Nuclear Power plants present a challenge in terms of overall inspection. Limited access and complex piping configurations restrict the type of indirect or direct NDE methodologies which can be applied by inspectors. Due to the complexity of buried and above-grade piping systems routed in and around these facilities, many plants have been forced to lo...
