Economic analysis of vapor reliquefaction in LNG carrier

Although the technique of chemical vapor generation has been developed forover l00 years, it sill plays an important role in modern analytical atomicspectrometry until today The technique has become popular fOr thedetermination of trace elements in the complex matrices and new aPproachescontinuously comes forth to improve the sensitivity and expand the scope ofaPplications.

Normal evaporation,vacuum evaporation and gas-carrying evaporation were adopted for treatment of old landfill leachate with different pH values.

In this paper the two main preparation technology, gas evaporation process and chemical reduction reaction process which can prepare ultrafine metallic powders in industrial scale are reviewed, several key issues on these preparation teehnologies are deeply discussed, and their dev(?) ment directions are forecasted.

Parameters of gas evaporation method to prepare the nano-particles of amorphous Ni-Ti alloy have been investigated.

Heat Transfer and Operating Characteristics of Gas Carrying Evaporation at Low Liquid Velocity;

Development of Gas Carrying Evaporation and Study of the Fouling on Its Heated Surface;

he principle and characters of the gas carrying evaporation(GCE)were introduced,The mecha-nism of hest transfer enhancement of GCE was expounded with the effect of the“vaporization heatsink”at the gas-liquid interface.
