In this paper,Based on the vapor-liquid equilibrium,the calculation method of gas stripping ethanol fermentation by the stripping efficiency was proposed.

Selects the most economical and reasonable operating load for the plant,by analyzing the operating parameters and factors influencing the stripping efficiency of SNAM ammonia stripper.

Calculates the influence of stripping efficiency on the low pressure system,analyzes and discusses the calculation results combined with the production practice, and puts forward some proposals and viewpoint

Starting with the structure of the SNAM ammonia stripper,analyzes the effect of the interior conditions and feed distribution on the efficiency of the stripper,then puts forward methods to change the feed distribution in the stripper in order to improve stripping efficiency.

Effect of the pump laser’s direction on the extraction efficiency of dye laser amplifier;

The authors studied the method of accelerated solvent extraction(ASE)for polychlorinated dibenzo-p-dioxins and dibenzofurans((PCDD/Fs))in soils,especially the conditions related to extraction efficiency such as extraction times.

Objective: To compare the extraction efficiency of imperialine extracted with different solvents.

After analysis to the effects of overheated steam parameters to waste to energy power generation system, this paper describes the main problems encountered in efficiency improvement for waste to energy power generation system and some solving ways to them.
