In this paper, a numerical simulation of the in situ retorting of continental oil shale in Northeast China was performed.
Depending on temperature, a reduction of 81% to 96% in furan levels was possible, compared with retorting. The more pressure-resistant strain was B.
According to the variations of the particle size, the Surface retorting of oil shale can be classified into two categories: lump shale process and particulate shale process.
The uniformity of gas flow in each part of the retorting zone was calculated by the same method as in literature [1], using Equation (1):
In case of surface retorting, oil shale needs first to be transported to the surface by open pit or underground mining.
"In retorting the limiting factor is usually heat conduction in the product," said Prof Richardson, "but this new process promotes much faster heat transfer for many products and gives impressively short process times--for example just 2.5 to 4 minutes for a typical soup formulation."
The distribution of the heating gas in the retorting zone and the pressure drop across the retort are responsible for heat exchange efficiency, products yield, oil quality, and the benefits of the oil shale retorting process.
In this paper, an oil shale comprehensive utilization system based on Huadian-type retorting technique is presented.
The automation aspects are only one part of the whole picture of a new era of retorting low-acid foods.
For successfully developing and optimizing the comprehensive utilization process of oil shale, the authors have recently explored a combined fluidized bed (FB) retorting and CFB combustion system of oil shale, and carried out a series of related investigations, including combustion characteristics of the semicoke CFB, retorting characteristics of the FB retort, energy analysis of the whole process, etc.
Prior to retorting, 2 containers in each crate are marked with the retort #, batch #, and crate #.
The new Du Pont retort computer model calculates oxygen and moisture barrier effectiveness of a particular multilayer configuration by factoring in such parameters as the properties and quantity of the resins being used, number of layers in the configuration, retorting conditions the material must face (temperature and residence time), and the conditions of storage of the container after retorting.
