Selection is based on extraction plant equipment safe, reliable, energy saving, less failure, easy maintenance, long life Principle, in the selection by the selection of new equipment with advanced energy-saving technology to achieve the best results. Specific performance in the following areas:
1) The continuous improvement of the fixed grid rotocel solvent Extractor
Appropriate to increase the height of the extractor feed grid will help improve circulation leaching effect. Increasing the height of the collection grid, and eliminating the need for mixing oil temporary storage tank. In order to prevent the oil from flowing back into the rich blanking grid, increasing the lateral grid.
2) DT toaster and desolventizer
After DT toaster and desolventizer improved, its upper structure is big hat head, material falling from the dispensing tray, one, two pre-off, three for the steam off, after four off, five dry.
The structure advantages: instead of four further desolventizing stage, can not properly heated or heated depending on the circumstances, can effectively avoid the high boiling solvent is evaporated without a net, resulting in a high solvent loss shortcomings; five drying, heating may be appropriate under the circumstances or directly with the cold, it proved 1050C direct cooling with cold air hot meal that is dry and has a good cooling effect, energy consumption is greatly reduced. In short, the improved steam offline DTD has to save power, save energy, low solvent loss, meal at the end of a small, significant advantage dried and cooled and used.
3) Condensor
It uses heat exchange theory, using cold water to condensate the evapated solvent gas and steam.
4) Stripper
The new stripper, a unique spherical baffles make oil flow uniformity and dispersion of the vapor and liquid contacting uniform, thorough, removing the solvent and strong ability level, and to reduce the production of vapor due to fluctuations in crude oil caused by residual solvent the phenomenon of low high when crude oil in total volatiles greatly reduced, to ensure the safety of leaching refining of crude oil.
