lm是LV旗下的包包吗

LVMH是LV的母公司，LV是LVMH的旗下品牌之一。

LVMH全名Louis Vuitton Mo?t Hennessy（法国酩悦·轩尼诗－路易·威登集团），1987年由贝尔纳·阿尔诺（Bernard Arnault）将路易威登（Louis Vuitton）与酩悦·轩尼诗（Mo?t Hennessy）公司合并而成，员工约五万六千人，旗下拥有50多个品牌，是当今世界最大的精品集团。

集团主要业务包括以下五个领域：葡萄酒及烈酒（Wines & Spirits）、时装及皮革制品（Fashion & Leather Goods）、香水及化妆品（Perfumes & Cosmetics）、钟表及珠宝（Watches & Jewelry）、精品零售（Selective Retailing）。

德国大众为什么要尾气排放作弊

其实就是技术原因，大众的尾气处理装置采用了EGR（Exhaust Gas Recirculation）系统，是将柴油机产生的废气的一小部分再送回气缸。再循环废气由于具有惰性将会延缓燃烧过程，也就是说燃烧速度将会放慢从而导致燃烧室中的压力形成过程放慢，这就是氮氧化合物会减少的主要原因。但这个东西缺点很明显，就是二次循环的气体质量变差了，富氧燃烧变少，自然影响动力，所以在正常行驶时不会经常开启EGR系统，排放肯定超标。一般的柴油机尾气处理都采用了SCR（Selective Catalyst Reduction）系统，这种系统主要以尿素为还原剂，对氮硫化物进行还原吸收，它对于废气的吸收效率比EGR会好很多，但它是要加装笨重的液罐来盛放尿素，考虑到节约成本和简化结构，大众的小型汽车自然不愿意来装个这种液罐，在柴油机中不做SCR系统只做EGR系统的只有大众一家，所以大众作弊就很好理解了，因为它没有办法处理轻量化，动力和尾气这三者的矛盾，为了轻量化和动力考虑，尾气就无法控制了。

谁能给介绍一下关于汽油脱硫方面的法国AXENS公司的 Prime-G+工艺

The basic design utilizes Axens’ Prime G+ process, which is a catalytic process for hydrodesulfurization of gasoline that includes the following sections:

• Selective Hydrogenation unit (SHU)

• Selective HDS Section

The most important part of this package is the selection of Catalysts and Chemicals,which are patented products Axens will supply.

The SHU effluent is mixed with the HDS recycle gas and the mixture is preheated and completely vaporized in some exchangers, then pass through two stage HDS reactors and one heater between or behind them. The effluent from the Second HDS Reactor is cooled by exchanging heat, in mixed phase, is flashed in the HDS Hot Separator Drum. The liquid phase ,in hige temperature,   is sent directly to the Stabilizer Section. The gas phaseis further cooled down in an air cooler and then go through the other two separator drums, further stripping liquid phase.The vapor phase is further cooled down under Lean Amine temperature to avoid gas condensation and resultant foaming in the Amine Absorber. Liquid is sent back to the separator and vapor flows to the Amine Absorber KO Drum to remove any entrained liquid droplets. And then the vapor phase flows to the Amine Absorber, where H2S is substantially removed from the recycle gas. In the Amine Absorber, the recycle gas is contacted with MDEA lean amine solution. The sweet gas leaving the Amine Absorber is routed to the Recycle Gas Compressors KO Drum. Apart of the vapor leaving the Recycle Gas Compressors KO Drum is purged under flow control to the refinery Fuel Gas System, to maintain the hydrogen composition of the recycle gas (this stream is normally no flow). The remaining gas flow constituting the recycle gas is routed to the suction of the Recycle Gas Compressors.

All above is a simple discription for a kind of Prime-G+ process. In different project ,there are different operation condition and treat capacity and so some differences in details.
