Oil Cakes

The pressed oil-extraction process is essentially a process of oil seepage through porous cake-shaped media. Permeability of seepage field changes along with the change of porous media caused by press pressure. The change of permeability affects fluid pressure and effective pressure of oil cake pores, which means that porosity is influenced. On the contrary, the change of porosity also has an impact on permeability. The interaction between the seepage and rheology fields is termed as fluid-solid coupling. If rheology of oil cakes is considered, the fluid-solid coupling seepage with the rheological properties is the essence of the pressed oil-extraction process. In the present study, we studied a permeability model based on the deformable and rheological properties of oilseed cakes and the effective stress. The seepage and rheology fields were analyzed by alternative application of the finite difference and finite element methods. The finite element calculation model of nonlinear rheology field was established by the time step-initial strain method. We used flax and cotton seeds as examples to perform numerical simulation and calculate the displacement and pore fluid pressure dissipation of flaxseed and cottonseed oil during the press process.

Choice Of Technique

This paper analyses the choice of techniques at the product level with a view to evaluating the claim made by Stewart [17] and others that "choice of technique is eliminated once choice of product is made". We consider the extraction of edible oil from cottonseed as a case study. Use is made of engineering data, coupled with product and factor price data from Pakistan, to examine the possibilities of factor substitution at the micro level for a reasonably well-defined product. The product in this case is well defined, although there are some qualitative differences associated with different methods of extraction.

The article considers the state of things in Russian oil refining. The options for its modernization are analyzed, as well as the effects of tax reforms in the sector. It is noted that current tax reforms mostly touch upon refining, not oil extraction, so one can expect further reforms in the sector and their impact on the industry.
