The Viability of Oil Extraction from Trinidad Tar Sands by Radio Frequency Heating: A Simulation Approach
Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...
متن کاملNitrogen starvation promotes biodegradation of N-heterocyclic compounds in soil
Mineralization studies were performed to examine the impact of N deprivation on microbial utilization of the N-heterocyclic herbicides, atrazine and cloransulam-methyl (C-M). Soil depleted by 130 years of cropping to Zea mays without fertilization was contrasted to soil from the same site regularly receiving fertilizers. Long-term N deprivation promoted rapid degradation of atrazine and the C-M...
متن کاملCoal Tar Analysis by Lc/ms
The production of liquids from coal gives rise to complex intermediates which require detailed analysis to understand the processes occurring and to make effective use of the products. Analysis has hitherto been based on structural parameters from NMR methods (1) to give the average characteristics of the sample, supplemented by molecular information from GC and GC/MS. The gas chromatographic a...
متن کاملRecycle Oil Pyrolysis and Extraction of Tar Sand
Western Research Institute is developing a new pyrolysis process called ROPE© (Recycle Oil Pyrolysis and Extraction) for recovering products from tar sands that require a minimum of upgrading to produce finished, marketable fuels or that can be used as a diluent to decrease the pour point of bitumen for transportation. The concept consists of two pyrolysis steps: (1) retorting tar sand at a low...
متن کاملCoal tars and coal tar pitches.
Numerous studies, mostly case reports, have found that occupational exposure to coal tars or coal-tar pitches (coal-tar distillates) is associated with skin cancer, including scrotal cancer; workers in these studies have included patent-fuel (coal-briquette) workers, pitch loaders, workers in electrical trades, and optical-lens polishers (IARC 1985, 1987). A 1946 study in the United Kingdom fou...
