Cold high-pressure separation process is now widely used in isomerization unit of PX complex, and results in an unreasonable energy consumption of PX complex. The advantages and the problems when using hot high-pressure separation process are analyzed. An accurate method for determination of isomerization product distribution is established. The hot high-pressure separation process is simulated by ASPEN PLUS, and the results indicate that recycle hydrogen concentration is almost not changed, compared with cold high-pressure separation process. Hot high-pressure separation process is proved to be feasible by industrial practice. The energy optimization scheme is proposed, and the simulation proves that the energy consumption of 370 kt/a PX complex can be reduced by 627 MJ/t.

The resonant tunneling model has been extended to p+6Li fusion reaction after its successful application in 6 major fusion reactions (d+T, d+D, d+3He, t+T, t+3He and p+D). It shows that 4 sets of different experimental data (fusion cross-section data, astrophysical S-factor, 7Be K-capture life-time, and anomalous isotope abundance ratio (7Li/6Li) in palladium-hydride) are related through this resonant tunneling model. It confirms that resonant tunneling is the mechanism underlying those 4 seemingly independent phenomena. Thus, hot fusion data has justified the Condensed Matter Nuclear Science which will lead to an environmentally safe nuclear energy technology.

The mechanism of biological treatment for VOCs is introduced. Three kinds of biological process for treating VOCs and their advantages and disadvantages are analyzed. The key factors that influence the performance of biological treatment for VOCs, such as packing media, nutrients, microorganisms, biomass control, are described in detail. Based on research development of biological treatment for VOCs, the potential applications of biological methods for VOCs in the future are prospected.

In combination with the operating parameters in the Marsulex ammonia method-based desulfurization process during Phase II of Yangzi thermal power plant, tested and investigated was the influence of the ammonia method-based desulfurization process parameters on the emission characteristics of aerosol. The research results show that in the process of ammonia method-based desulfurization, a large quantity of aerosol particles may be produced to cause a remarkable change of the physical properties of particles before and after the desulfurization. The emissions of aerosol will increase with an increase of the air speed in the air tower, pH value and concentration of the desulfurization solution, flue gases and desulfurization solution temperature, liquid-gas ratio and SO3 concentration of the flue gases. Compared with a sprinkling air tower, a packing tower and a sieve-tray tower will have relatively low emissions of aerosol. Finally, based on the law influencing the ammonia method-based desulfurization process parameters, the mechanism governing the formation of aerosol particles in the ammonia method-based desulfurization device of Yangzi thermal power plant during its Phase II construction period was analyzed.
