The design of the Large Hadron Collider (LHC) vacuum system requires a complete understanding of all processes which may affect the residual gas density in the cold bore of the 1.9 K cryomagnets. A wealth of data has been obtained which may be used to predict the residual gas density inside a cold vacuum system exposed to synchrotron radiation. In this study the effect of cracking of cryosorbed...

The efficiency of the application of high-emissivity coatings on the furnace walls in steam cracking technology can only be evaluated on the asis of a description of radiative heat transfer distinguishing between the frequency bands. To this end, a non-grey gas radiation model based on he exponential wide band model (EWBM) has been developed and applied in the context of three-dimensional CFD s...

In particular, a straw-based Ablative Fast Pyrolysis (AFP) oil was upgraded via hydrotreatment (HDT) in order to be used as blending component with fossil-based intermediates. The raw pyrolysis is characterized by H/C = 0.14, O/C 0.58 and C 57.73 wt%, while the HDT has 0.016 85.85 wt%. Based on density, viscosity composition, association typical refinery, possible petroleum refinery entry point...

Disposal of concentrate from brackish water desalination plants by deep well injection into oil and gas fields is an attractive option in Texas. Underpressured depleted oil and gas reservoirs cover large areas of the state. Six areas were selected from across Texas for detailed analysis. These sites were characterized by abundant brackish groundwater, a projected shortage of freshwater, deplete...

A lot of oil and gas reservoirs have been or will be abandoned in petroleum industry. In this study, we pointed out that these oil and gas reservoirs might be transferred into exceptional enhanced geothermal reservoirs with very high temperatures by oxidizing the residual oil with injected air. A concept to generate power from these exceptional enhanced geothermal reservoirs by using geothermal...

This report discusses various types of environmental waste products, current status of waste destruction, and the application of plasma technology for waste treatment. Plasma processes are divided into three types: open bath systems, shaft furnaces, and gas-cracking systems. These three types of plasma systems have the capability of treating a large number of different types of wastes and reduc...

ZSM-5-containing catalytic additives are widely used in oil refineries to boost light olefin production and improve gasoline octanes in the Fluid Catalytic Cracking (FCC) process. Under the hydrothermal conditions present in the FCC regenerator (typically >700 °C and >8% steam), FCC catalysts and additives are subject to deactivation. Zeolites (e.g., Rare Earth USY in the base catalyst and ZSM-...

The price of a barrel of crude oil doubled within a few months last year. Although prices have been easing lately, for those who paid more than $3 for a gallon of gas, the memory is not likely to fade quickly. But worries about higher gas prices don’t end at the pump. Oil price shocks—sudden and sharp increases in the price of oil and its derivatives like gasoline—are associated in the popular ...
