求职自荐书（Self recommendation） Summary In August 31, 2006, our leaders led by the teacher, we came to Qingdao Jiaonan City Hengyuan chemical plant started as a trainee for ten days of the principle of chemical engineering. This internship aims: according to the principle of chemical engineering course last semester we opened, practical understanding of the actual production of chemical process, to better consolidate the principle of chemical knowledge and improve the practical ability and operation ability. Qingdao City Hengyuan chemical factory established in 1968, put into operation in 1969. In the early 90s, the United States introduced nitric acid production equipment, and gradually increased the production of sodium nitrate, sodium sulfate, organic nitrobenzene, aniline and other products. Gradually become a large chemical enterprise with aniline as its flagship product. The factory has more than 200 employees, with an annual output value of more than 700 million yuan, turning over aboutyuan in profits and taxes, and living in the top twenty private enterprises in Qingdao and five hundred in the national chemical industry. In 2002, our factory successfully acquired Jiaozhou fertilizer plant, and successfully realized the transformation of the plant. This internship, we mainly learn two sodium (sodium nitrate, sodium nitrite) production workshop of the chemical process. The main products of this workshop are sodium nitrate and sodium nitrite. The raw materials used are ammonia gas and sodium hydroxide. The process flows are oxidation, absorption, evaporation, crystallization and conversion. 2. each post task 2.1 oxidation post The task of this position is to produce nitrogen oxides by oxidizing ammonia gas with high temperature, which is the raw material for the next step. 2.2 post absorption The job of this position is to react with sodium hydroxide, the intermediate product of oxidation post, to realize the absorption of nitrogen oxides and to produce th
