【正文】 g and synthetic ammonia in ammonia production energy saving transformation provides a reasonable reference. Keywords: synthetic ammonia technology actuality Energy saving Summary: Synthetic ammonia is one of the bulk chemical products, the synthetic ammonia production has reached more than 100 million tons per year, ammonia synthesis products as an important chemical products, can be used for nitrogen fertilizer, nitrate and ammonium fertilizer production processing manufacturing. China39。s synthetic ammonia production of million tons in October 2020, October 1 cumulative output was million tons, yearonyear increase of %. With the constant improvement of the market for synthetic ammonia product requirements as well as the national to the requirement of chemical industry energy conservation and emissions reduction, improvement of synthetic ammonia production technology, increasing energy conservation technology development, should be the synthetic ammonia chemical industry urgently needs to solve the main problems related to. In recent years, China39。s international and domestic large ammonia plant using advanced technology, equipment and control technology, a lot of technical reform, practice has proved that the technology is advanced, mature, reliable, and used for transformation of enterprises to choose. 一、現(xiàn)階段合成氨工業(yè)主要生產(chǎn)原料 合成氨 反應(yīng)公式為 QNHNH ??? 322 23 ,合成氨的反應(yīng)特點主要為:可逆反應(yīng),氫氣與氮氣反應(yīng)生成氨,同時氨在一定條件下也可以分解成氫氣和氮氣;此外,合成氨的反應(yīng)為放熱過程,反應(yīng)過程中反應(yīng)熱與溫度以及壓力有關(guān);而且需要催化劑的催化方能迅速進(jìn)行合成氨反應(yīng)?,F(xiàn)階段用硬合成氨生產(chǎn)的原料主要有 重質(zhì)油、 天然氣、以及煤或焦炭,具體生產(chǎn)工藝如下所示:
