The convection and microlayer evaporation heat transfer contributions to boiling heat transfer outside a horizontal tube bundle were distinguished by limiting difussion current technique and heat transfer measurements simultaneously.

The glycerol,a by-product of biodiesel preparation from Jatropha curcasl oil(barium hydroxide as catalyst),was refined by the method of combined ion exchange process and film evaporation of pipeline,and the parameters were optimized.

We had made full use of the flavoring components in double bottom distiller′s grains and the strong fermentation properties of Angel brand TH-AADY through application of TH-AADY coupled with the techniques of double bottom fermentation, fermentation of reflux liquor and cross-steaming for thin layers etc.

Separation technology of thin-film evaporation of tolylene diisocyanate monomer;

With the action of blades' wiping,thin-film evaporation method is characterized by short residence time,low evaporation temper- ature and ability to deal with high viscous pre-polymer,and suitable for monomer's separation.

The free toluene diisocyanate(TDI) in the curing agent TDI-TMP(Trimethylol Propane) of polyurethane was separated in laboratory by means of high-vacuum two-stage thin-film evaporation.

In order to distil free TDI from the PU curing agent with thin-film Evaporator,a suitable curing agent should be a small molecular weight and reacted thoroughly.

VE liposome was prepared by thin-film evaporator and high pressure homogenization method.

Firstly, the working principle of the thin-film evaporator and the related auxiliary equipment were introduced.
