The first step having been in progress designs the section of construction project who designs that contact process changes in the process producing sulfuric acid originally to annual output of 100,000 tons. Adopt three, one twice paragraphs of style to change technological process four paragraphs. Accounting carrying out material and quantity of heat on what be elected technological process, the dimension , the dimension carrying out handicraft on main equipment heat exchanger in technological process calculate the cardinal principle ascertaining the conversion implement , choose a type. And have carried out the core of school on heat passage modulus and area. Design that result indicates a heat exchanger meeting the requirement.文章有些长、、望认真看完、、标准人工翻译、、希望可以帮助你、、The design annual production capacity of 100,000 tons of exposure to sulfuric acid production process into a preliminary design section. The use of two three or four paragraphs into a period-style process. The process of the selected material and heat balance to determine the general size converter for the main process equipment for process heat exchanger size, the selection. Heat transfer coefficient and area of a check. Design results show that the combined heat exchanger. Keywords: sulfuric acid, the transformation of sulfur dioxide, heat exchanger, processa; h. the selection of activated carbon oxidation which; year;m3 emission flow rate of 1.5553 million yuan /, oxidation - absorption and adsorption, the actual operating costs 389.7t /, by-product benefits of 2, the emission characteristics of normal temperature and pressure, less than the national nox emission standard (gb16297-1996), absorption solution using naoh solution, using a vapor phase catalytic oxidation - alkali absorption process design; year.1t /.1658 million yuan /, two absorber to absorb nox emissions; h.results. absorption of liquid by simple treatment with a certain economic value byproduct nano2380.the design process include, one has become an important research topic for the field of environment;m3 40m row the pump flow rate ≤ 4.15mg/. (yield) of total operating costs of 2.4kg /. the design for the pharmaceutical factory emissions including nox exhaust gas oxidation, in addition to water adsorbent.14mg/: after two absorber absorption treatment, and nano3423, catalyst selection of zsm-5 zeolite, the absorber tower; a: the exhaust of nox in addition to water and oxidation. [14] the denitration method commonly used in industrial emissions containing nox absorption method: the concentration of ≤ 0,500 yuan, the final nox concentration of export emissions 0, byproducts of separation purification of nano2 and nano3 the separation and purification of three partsthe gas phase catalytic oxidation - the alkali absorption method to handle nox industrial emissionspreliminary design of process systemsabstractnitrogen oxides (nox) cause great harm to the ecological environment and human health.256kg /The design annual production capacity of 100,000 tons of exposure to sulfuric acid production process into a preliminary design section.
