The Stability

Chlorophyll and xanthophyll dyes extracted from a single source of filamentous freshwater green algae (Cladophora sp.) were used to sensitize dye sensitized solar cells and their performances were investigated. A more positive interaction is expected as the derived dyes come from a single natural source because they work mutually in nature. Cell sensitized with mixed chlorophyll and xanthophyll showed synergistic activity with improved cell performance of 1.5- to 2-fold higher than that sensitized with any individual dye. The effect of temperature and the stability of these dyes were also investigated. Xanthophyll dye was found to be more stable compared to chlorophyll that is attributed in the ability of xanthophyll to dissipate extra energy via reversible structural changes. Mixing the dyes resulted to an increase in effective electron life time and reduced the process of electron recombination during solar cell operation, hence exhibiting a synergistic effect.

Demulsification Efficiency

In view of the serious emulsification existing in Changqing condensate gas emulsion, the unclear oil-water interface and the poor application effect of demulsifier used in the field, it is urgent to study an efficient demulsifier. In this paper, PM and XP-1221 two kinds of demulsifiers are used to solve the emulsification problem. The PM demulsifier was compounded with XP-1221 chemical demulsifier to solve the emulsification problem of Changqing condensate. The effect of temperature and demulsifier concentration on demulsification performance was studied by bottle test method. The results showed that XP-1221 and PM could be effectively combined. The demulsification efficiency was high and the dehydrated water was clear. Studies have shown that XP-1221 has a good synergistic effect with PM. The suitable ratio of the composite demulsifier is 1:1, and the demulsifier effect of the demulsifier can meet the requirements of the oil field demulsifier. The composite demulsifier can meet the requirements of current oilfield demulsifiers.
