我國工業(yè)甲醛生產(chǎn)工藝方法,對生產(chǎn)工藝過程中甲醇消耗高的原因進(jìn)行分析,并對造成甲醇消耗高的主要因素如氧化脫氫反應(yīng)轉(zhuǎn)化不完全、副反應(yīng)生成、甲醛吸收塔吸收效率低等問題進(jìn)行了討論,提出了使用性能優(yōu)良的催化劑、優(yōu)化反應(yīng)工藝條件、提高甲醛氣體冷卻、吸收效率等降低甲醇消耗的途徑和措施。
甲醛溶液中甲醇是重要的指標(biāo)，需要嚴(yán)格控制。浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司采用專用填充柱甲醛進(jìn)行氣相色譜法檢測甲醇含量，含量低的甲醇首先流出，是此柱的一大特色，保證了甲醇無覆蓋，定量準(zhǔn)確可靠。

China's industrial formaldehyde production process method, analyzes the reasons for high methanol consumption in the production process, and discusses the main factors causing high methanol consumption, such as incomplete oxidation dehydrogenation reaction conversion, side reaction generation, low absorption efficiency of formaldehyde absorption tower, and puts forward the use of catalysts with excellent performance, optimization of reaction process conditions, improvement of formaldehyde gas cooling Absorption efficiency and other ways and measures to reduce methanol consumption.
Methanol in formaldehyde solution is an important indicator and needs to be strictly controlled. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a special packed column of formaldehyde to detect the methanol content by gas chromatography. The methanol with low content flows out first, which is a major feature of this column, ensuring that the methanol is not covered, and the quantity is accurate and reliable.
