The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...

Petrochemical and Petroleum refining sector has become the backbone of the economical development. The costs of all the consumer goods are closely governed by cost of petroleum products. Diesel and petrol are two most widely used liquid fuels in the world. The cost of the fuel depends on the raw material. The optimization of the reaction carried out in these industries can save some cost and ad...

Petroleum oil is a complex mixture of substances, the majority of which are hydrocarbons; the latter represent an extremely important and heterogeneous group of compounds that find their way into water resources by anthropogenic or natural ways. The majority of toxic hydrocarbon components of petroleum are biodegradable, where bioremediation using microbial species has become an integral proces...

UNLABELLED BACKGROUND Petroleum pollution is a global disaster and there are several soil cleaning methods including bioremediation. METHODS In a field study, fugal strains were isolated from oil-contaminated sites of Arak refinery (Iran) and their growth ability was checked in potato dextrose agar (PDA) media containing 0-10% v/v crude oil, the activity of three enzymes (Catalase, Peroxid...

Many seabirds die each year after exposure to petroleum hydrocarbons (Piatt and Lensink 1990; Khan and Ryan 1991). Crude oil, following ingestion, induces hemolytic anemia which occurs 4 to 5 d later (Leighton et al. 1983). A recent study reported the presence of hemosiderin in the liver of common murres (Uria aalge) at intervals up to 42 d after oil-contamination (Khan and Ryan 1991). Hemoside...

Petroleum products bought and sold on the world wide market may be transported over thousands of miles and change ownership many times from the well head to the end user. Each time the product changes ownership, a “custody transfer” is completed and both buyer and seller expect their asset share to be accurately measured. The dynamic measurement provided by meters is a convenient and accurate m...

BACKGROUND The management of burns remains a challenge in developing countries. Few data exist to document the extent of the problem. This study provides data from a suburban setting by documenting the epidemiology of burn injury and ascertaining outcome of management. This will help in planning strategies for prevention of burns and reducing severity of complications. METHODS A total of 72 p...

The corrosion protection of petroleum storage tank is important for safety work in petroleum depot. Precise prediction of soleplate corrosion may reflect the security state of a storage tank, and it can provide scientific references to the anti-corrosion and maintenance in safety management. Grey Model GM (1,1) in the Grey Theory is a good prediction method based on small volume of original dat...

The objective of our study was to investigate the possible interactive effect of occupational exposure to extremely low-frequency magnetic field (ELFMF) and to known or suspected carcinogenic chemicals on the incidence of the two main histological types of brain cancer, gliomas and meningiomas, in a cohort of male Swedish workers. The historical cohort of all Swedish men gainfully employed in 1...

Product distribution account for a significant portion of the logistical costs of a product. Distribution activities are repetitive in nature and they impact the delivery lead time to customers. A well designed supply chain network can substantially improve these costs and lead times. This paper presents a supply chain network design approach for distribution of petroleum products of a retailer...
