求高手帮我翻译一段文字

请高手帮我翻译下这段文字,谢谢!
近年来，在全球对醋酸需求有所下降的同时，我国对醋酸的需求却增长迅速，国内几套甲醇羰基合成醋酸装置的投产，使醋酸能力和产量有了长足增长，但生产仍不能满足需求，进口量增长速度较快。
以甲醇为原料合成醋酸，不但原料价廉易得，而且生成醋酸的选择性很高，在现有的醋酸生产企业中，甲醇羰基合成工艺装置开工率接近100%。
对于年产20万吨的甲醇碳基化法醋酸装置的反应器安全设计，本文将首先对反应器进行物料衡算，计算出主、副产品的产量，原材料的消耗定量等。同时根据衡算所得反应器单元的流量及其组成、能量负荷，对反应器进行选型或设计。
在反应器的选型过程中，将根据甲醇碳基化制醋酸工艺的特点选择合适的反应器，并对反应器的体积、直径等相关的参数进行计算。
最后将对反应过程中可能出现的危险性进行分析，特别是分析反应器在反应中的危险性。

Answer 1

In recent years, global demand for acetic acid decreased the same time, China's demand for acetic acid has grown rapidly. China sets methanol carbonylation acetic acid plant into production, and production capacity of acetic acid with substantial growth However, production is still unable to meet the demand, imports grew faster. Methanol to acetic acid as raw materials, not only of raw materials are cheap, but production of acetic acid highly selective, of the existing acetic acid production enterprises, methanol carbonylation technology devices operating rate close to 100%. For an annual output of 200,000 tons of carbon-based methanol method of acetic acid plant reactor safety design, This paper will be the first pair of reactor material accountancy, calculated the main, by-products production, the consumption of raw materials such as quantitative. According to accountancy from the reactor unit volume and composition, energy load, the reactor for selection or design. Reactor in the selection process, according to carbon-based methanol acetate system of the characteristics of selecting suitable reactor, The reactor size, diameter and other related parameters are calculated. Finally reaction process will possibly arise in the risk analysis, in particular to analyze reactor in response to the danger.

Answer 2

In recent years, had drop while the whole world to the acetic aciddemand, our country actually grows to the acetic acid demand rapidly,domestic several sets of methyl alcohol carbonyl synthesis acetic acidinstallment going into production, caused the acetic acid ability andthe output had the considerable growth, but produced still cannot meetthe need, the import quantity rate of rise is quicker. Take methyl alcohol as raw material synthesis acetic acid, not onlythe raw material moderate price is easy, moreover the productionacetic acid selectivity is very high, in the existing acetic acidproduction enterprise, the methyl alcohol carbonyl synthesis craftinstallment utilization of capacity approaches 100%. Regarding will yearly produce 200,000 tons methyl alcohol carbon basereduction acetic acid installment the reactor safety design, thisarticle first carries on the material to the reactor, the graduatedarm calculated that, will calculate the host, the wastage output, theraw material consumption quota and so on. Meanwhile according to thegraduated arm calculated the obtained reactor unit the currentcapacity and its the composition, the energy load, carries on theshaping or the design to the reactor. In the reactor shaping process, will act according to the methylalcohol carbon base system acetic acid craft the characteristic choiceappropriate reactor, and to correlation the and so on reactor volume,diameter parameter will carry on the computation. Finally the risk which will possibly appear to the reaction process incarries on the analysis, specially will analyze the reactor inresponse risk.
