According to the invention of the technology, Zhang Lianhe, director of the humane Anlilong Welfare Chemical Plant, introduced that the traditional formaldehyde production process uses refined alcohol as the raw material and methanol dehydrogenation to formaldehyde as a catalyst. Semenol needs to be purchased from various chemical fertilizer plants or methanol plants. These manufacturers basically use crude coal or natural gas as raw materials to make crude methanol, and many of the impurities contained directly affect the production of formaldehyde. Since crude alcohol cannot be used directly in production, it must be rectified to produce industrial wastewater containing 4% to 5% methanol. In this way, there are many additional costs in the rectification and pollution control processes.
Wenan Lilong Welfare Chemical Plant has successfully developed the methanol disintegrator after six years of research and development. The crude alcohol can be directly used by formaldehyde manufacturers after being processed by the methanol high-efficiency dissociator, and does not affect the performance and life of the catalyst. Direct use of crude alcohol will not cause catalyst poisoning. According to reports, after the methanol dissociator is used, it is only connected to the existing formaldehyde production equipment in series and in parallel. It does not increase any power, does not produce waste liquid, and therefore does not cause environmental pollution. The produced formaldehyde products fully comply with national standards.
Zhang Lianhe told reporters that after using a methanol dissociation device, formaldehyde manufacturers can purchase crude alcohol directly from a fertilizer plant or a methanol plant for formaldehyde production. From the perspective of economic efficiency, based on the current market prices for refined alcohols and crude alcohols, the use of crude alcohol as the raw material can significantly reduce the cost of raw materials compared to the raw materials of refined alcohol, which in turn can reduce the cost by about 100 yuan per ton of formaldehyde produced. And social benefits are significant.
In addition, the formaldehyde equipment produced by the plant can be parked and driven at any time without affecting the catalyst performance and without increasing production costs. Even if you drive after stopping for 15 days, you do not need to perform any treatment on the catalyst. This will not only reduce losses but also reduce labor intensity. It is reported that as of now, the formaldehyde equipment produced by this plant has been used by a number of formaldehyde plants in Beijing, Shanxi, Inner Mongolia, Shandong, Henan and Hebei, and has received good results.
The new "green" process saves energy, raw alcohol, direct formaldehyde, and reduces costs by hundreds of yuan.
The use of crude methanol to produce formaldehyde directly reduces the cost per ton of formaldehyde by about 100 yuan. The application of this new technology significantly reduces the input of raw materials and generates no waste liquid, which allows the formaldehyde business to bid farewell to the high cost and pollution. Traditional crafts. This is what the reporter saw when he was interviewed on August 9 at the Wen'nan Lilong Welfare Chemical Factory in Hebei.
