Energy conservation and consumption reduction are continuously promoted. Under this background, the waste gas management of maleic anhydride manufacturing industry has become the top priority of the manufacturing industry; In China's Yangtze River Delta region, it is an explicit rule that the new maleic anhydride consumption and manufacturing project under construction must be equipped with relevant maleic anhydride waste gas management equipment, and then adhere to the stable environmental protection standard of benzene containing waste gas. Otherwise, the establishment of the project has not been reviewed.

顺酐

Maleic anhydride

为合理防治顺酐有机废气环境污染伤害，在我国一些顺酐公司曾尝试对含苯有机废气展开整治，但由于加工工艺冗杂，未有完善合理的整治技术性。据统计，资本主义国度纵有完善整治技术性和武器配备，依据催化反响燃烧处置等办法支配有机废气环境污染，可是引进技术价钱比拟贵。前段时间，某些公司在根本建立万多吨顺酐消费流水线时，消费制造设备项目投资为600多万，而引入顺酐废气管理技术性与武器配备的项目投资就超出了1000万余元。

In order to reasonably prevent and control the environmental pollution damage of maleic anhydride organic waste gas, some maleic anhydride companies in China have tried to rectify the benzene containing organic waste gas, but due to the complex processing technology, there is no perfect and reasonable remediation technology. According to statistics, although capitalist countries have improved remediation technology and weapons, and control organic waste gas environmental pollution according to catalytic reaction combustion disposal, the price of imported technology is relatively expensive. Some time ago, when some companies fundamentally established more than 10000 tons of maleic anhydride consumption lines, the investment in consumer manufacturing equipment projects was more than 6 million, while the investment in projects introducing maleic anhydride waste gas management technology and weapon equipment exceeded more than 10 million yuan.

除此之外，在依据催化反响燃烧处置顺酐有机废气时，由于要加上燃气、植物油脂等然料，运作本钱费也令人震惊。以年产量两万吨级顺酐的新项目为例，废气管理每钟头消耗燃气1640立方，年运作破费达1600多万元，形成公司比拟严重赔本。

In addition, when disposing of maleic anhydride organic waste gas based on catalytic reaction combustion, the operation cost is also shocking due to the addition of natural materials such as gas and vegetable oil. Taking the new project with an annual output of 20000 tons of maleic anhydride as an example, the waste gas management consumes 1640 cubic meters of gas per hour, and the annual operation cost reaches more than 16 million yuan, forming a relatively serious loss for the company.
