富氧燃烧技术在石灰回转窑中的应用研究及经济性预测

利用燃烧学理论及其相关知识对富氧燃烧技术的特点进行了详细的理论分析.在此基础上针对某公司拟在石灰回转窑中应用该技术的工程案例进行了计算,提出了3种不同的技改方案,并对其经济性进行了预测.结果表明在不改变现有燃烧设备的条件下,采用焦炉煤气和转炉煤气混合富氧的方案,氧体积分数控制在21.4%时最为合理;采用焦炉煤气和高炉煤气混合富氧的方案,氧体积分数控制在23.0%时最为合理;从成本分析前者更具有竞争性.如果对现有燃烧设备进行改造,建议采用转炉煤气和高炉煤气混合富氧的方案,氧体积分数控制为28.0%时,成本节约潜力最大,对该公司最有实用意义,此时对应的煤气流量约为20 km3/h.

The partition coefficients of ethylene between hydrate and vapor for methane + ethylene + water and methane + ethylene + SDS + water systems

The hydrate formation of CH₄+C₂H₄ mixture was studied experimentally in two different cases, with and without the presence of sodium dodecyl sulfate (SDS) in water. The results manifested that the presence of SDS could not only accelerate the hydrate formation process, but also increase the partition coefficient of ethylene between hydrate and vapor drastically. The partition coefficients of ethylene between hydrate and vapor for methane + ethylene + water with the presence of 500 ppm SDS in water were then systematically measured. The experimental temperature ranged from 273.15 to 278.15 K, the pressure ranged from 2.5 to 5.5 MPa, the initial gas-liquid volume ratio ranged from 95 to 240 standard volumes of gas per volume of liquid, and the mole percentage of ethylene in feed gas mixture ranged from 5.28% to 79.36%. The results demonstrated that ethylene could be enriched in hydrate phase and partition coefficients were increased with the presence of SDS in water. This conclusion is of industrial significance; it implies that it is feasible to recover ethylene from gas mixture, e.g., various kinds of refinery gases or cracking gases in ethylene plant, by forming hydrate.     

Electrolytic recovery of chlorine from hydrogen chloride gas with fused molten salt electrolyte LiCl/KCl

A method of electrolytic recovery of chlorine from hydrogen chloride gas based on the fused molten salt LiCl/KCl is under development. For the feasibility study, described here, a reticulated vitreous carbon (or porous carbon) cathode was immersed in a low-melting eutectic of LiCl/KCl. A graphite rod was used as the anode. Gaseous dilute hydrogen chloride, in a mixture with nitrogen, was reduced to elemental hydrogen and chloride at the cathode, and chlorine was produced at the anode. At stoichiometric current, current efficiency is greater than 90%. The removal efficiency is as high as 97%.Patent pending (May 1995).
