Abstract:

The article evaluates the concentration of oil in the atmosphere of Barnaul by an indirect method of measurements which is based on the results of fluorimetric analysis of snow cover. Snow sampling was carried out at the time of maximum snow accumulation in the first decade of March 2013–2017. The concentration of oil in the urban snow cover exceeds the concentration in the control point outside the town by a factor of 2–6, which indicates urban atmosphere pollution. Especially high concentrations of oil are detected at the points located near the intensively loaded urban highways. Analysis sh

Abstract:

Abstract At a number of enterprises, there is a problem of wastewater treatment from oil products. It was studied the oil products composition in the wastewater in industrial sewage system of a machine-building plant. Gravimetric method was used to determine the concentration of oil products in wastewater. When detecting oil products in concentrations exceeding the MPC, it was researched the wastewater treatment from petroleum products by precipitation. It was also calculated the granulometric composition of oil products in wastewater and the main design parameters of the settling tank.

Abstract:

Long-distance pipelines transporting multiple product oils such as gasoline, diesel and jet fuel, are important facilities for transporting fossil energy. One major concern in operation is the energy consumption of the pipeline. Energy consumption should be made optimized tracking batches of oils and cutting mixed oil, which requires an accurate prediction of concentration curve. In engineering, the concentration curve is usually assumed to be symmetric, but it is actually asymmetric, which may lead to estimation errors. Thus, the asymmetric concentration of mixed oil should be studied. The fo

There are chemicals in bio-oil which are highly valuable as specialty chemicals, such as furfural, levoglucosan and levoglucosenone.

In the present study, an effective and environmental-friendly process using tri-iron tetroxide sorbent (Fe-O) to simultaneously degrade brominated epoxy resin from WPCBs was developed in pyrolysis process.

Disposal of storage tank sludge in oil depots is a major environmental concern due to the high concentration of hydrocarbons involved. This paper investigates the reduction of the sludge oil pollutants with initial oil and grease concentration of about 50 mass% using low cost adsorbents. Among the examined adsorbents, sawdust indicated the maximum removal of oil and grease. The screening and optimizing of process parameters were evaluated employing Plackett-Burman design and response surface method. For the optimized conditions, more than 60 mass% of oil and grease from the sludge was removed.

AbstractSeeds kept in long-term storage are essential for maintaining genetic resources of crops and other plant materials in seed banks and national germplasm systems. But seeds undergo chemical changes over time as part of the ageing process that result in reduced germination rates and seedling normalcy. For example, oilseed crops such as peanuts are particularly vulnerable to oxidation and rancidification due to their high oil content. To test the effect of storage time on seed oil in peanuts, we grew different accessions and harvested fresh seeds to compare the oil composition of new seeds
