- The solubilities of concentrate solution system of NC-DEP increase with the increase of its solvent ratio.
- So some renovations should be made,for example,increasing the solvent ratio of propane deasphalting;using hydrofinishing instead of clay treating;mo...
- RESULTS: The extraction rates was affected by extract solvent, extract times, Coccus- solvent ratio and extract temperature.
- The effects of the solvent ratio, the dilution solvent ratio and deoiling temperature on the slack wax deoiling were examined.
- The results show that this solvent offers the advantages of lower solvent ratio, higher filtration rate and higher product yield as compared with conventional solv...
- The source of PT acid in PTA, the crystal principle of PT acid and PTA, the variable factors cooling speed arid solvent ratio in the crystal process were analysed.
