13. USO DO RESÍDUO OLEOSO DAS ATIVIDADES DE EXTRAÇÃO DE PETRÓLEO EM MANUTENÇÃO DE ESTRADAS: UM ENFOQUE ECONÔMICO E AMBIENTAL
The aim of this work was the development of safety procedures for the application of oily waste in unpaved road maintenance. This waste is generated in the operations of oil exploration and production. The work also aimed to develop equations for calculations of the total cost involved in this application, enabling a cost comparison with other discarding alt

14. Aplicação de rede neural artificial como auxiliar na predição do desempenho de um landfarming
Esta pesquisa está dirigida para adicionar ao que até o momento existe de desenvolvimento sobre a tecnologia de biorremediação chamada landfarming que se destina ao tratamento no solo de resíduos sólidos orgânicos biodegradáveis, devido a grande diversificação de bactéria capaz de destruir esses resíduos. A tecnologia landfarming foi desenvolvida

15. Free-Living Dinitrogen-Fixing Bacteria Isolated from Petroleum Refinery Oily Sludge
Dinitrogen-fixing activity (acetylene reduction and 15N2 fixation) was found in an oily sludge originating from a petroleum refinery. Two representative dinitrogen-fixing bacterial strains were isolated from this oily waste. Their nitrogenase activity was effective when they were cultivated on sterilized sludge or simple carbon substrates (organic acid salts

16. Fate of Hydrocarbons During Oily Sludge Disposal in Soil †
A 1,280-day laboratory simulation of the “landfarming” process explored the fate in soil of polynuclear aromatics (PNAs) and total extractable hydrocarbon residues originating from the disposal of an oily sludge. In addition to the measurement of CO2 evolution, periodic analyses of PNAs and hydrocarbons monitored biodegradation activity. The estimation o

17. Effect of environmental parameters on the biodegradation of oil sludge.
A laboratory study was conducted with the aim of evaluating and optimizing the environmental parameters of "landfarming", i.e., the disposal by biodegradation in soil of oily sludges generated in the refining of crude oil and related operations. Oil sludge biodegradation was monitored by CO2 evolution and by periodic analysis of residual hydrocarbons. The pa
