【摘要】：四溴雙酚A是基礎(chǔ)有機化工原料。隨著國家經(jīng)濟的發(fā)展,房地產(chǎn)及基礎(chǔ)設(shè)施建設(shè)大力發(fā)展,且無機阻燃劑并未形成成熟的市場供求關(guān)系的情況下,對高質(zhì)量水平有機阻燃劑需求量有居高不下之勢,尤其是阻燃劑產(chǎn)品四溴雙酚A需求量更是供不應(yīng)求。四溴雙酚A生產(chǎn)廠家為了滿足企業(yè)自身的生產(chǎn)需要,采用新技術(shù)進行改造,以投入較少的投資來謀取更大的經(jīng)濟效益。因此,研究原廠生產(chǎn)裝置進行增產(chǎn)節(jié)能改造是十分有意義的。本設(shè)計是利用國內(nèi)先進技術(shù),采用可靠的氯苯溶劑法制取四溴雙酚A,通過對原生產(chǎn)單位經(jīng)驗的總結(jié)歸納與國內(nèi)外先進生產(chǎn)技術(shù)、節(jié)能技術(shù)的結(jié)合提出諸多改造方案。對該公司年產(chǎn)1萬噸四溴雙酚A進行增產(chǎn)節(jié)能改造,改造后目標為年產(chǎn)2萬噸。主要內(nèi)容包括:改造的現(xiàn)狀基礎(chǔ)、改造方案、工藝流程設(shè)計、流程說明、主要設(shè)備說明和技術(shù)經(jīng)濟分析。以此優(yōu)化生產(chǎn)裝置,提供項目改造的物料平衡數(shù)據(jù)以進一步作公用工程、單元設(shè)備和管道設(shè)計用等。經(jīng)過初步的技術(shù)經(jīng)濟分析,本改造方案內(nèi)部收益率高于行業(yè)的基準收益率,投資回收期短,表明方案是可行的。通過改造可節(jié)約投資,降低生產(chǎn)成本,又能產(chǎn)生較好的經(jīng)濟效益和社會效益。
[Abstract]:Tetrabromobisphenol A is the basic organic chemical raw material. With the development of national economy, the development of real estate and infrastructure, and inorganic flame retardant has not formed a mature market supply and demand relationship. The demand for high quality organic flame retardants is very high, especially the demand for tetrabromobisphenol A (BPA), especially for flame retardants. It is very meaningful to adopt the new technology to transform and obtain greater economic benefits with less investment. Therefore, it is very meaningful to study the production plant of the original plant to carry out the retrofit of increasing production and energy saving. This design is based on the advanced technology in our country. Tetrabromobisphenol A was prepared by using reliable chlorobenzene solvent method. The experience of the original production unit was summarized and the advanced production technology at home and abroad was summarized. With the combination of energy saving technology, many retrofit schemes are put forward. The annual production of tetrabromobisphenol A in the company is increased and energy saving is carried out, and the target after the retrofit is 20,000 tons. The main contents include: the current status of the transformation, the transformation scheme, Process flow design, process description, main equipment description and technical and economic analysis. Optimize the production plant, provide the material balance data of the project transformation for further public works, Through preliminary technical and economic analysis, the internal rate of return of the modification scheme is higher than the industry benchmark rate, and the investment payback period is short, which indicates that the scheme is feasible. Reduce production cost, can also produce better economic and social benefits.
