cold crystallization meaning in English

冷结晶

With the increase in production load , there is heavy liquid entrainment from the rectification column , resulting in a rise in urea content in the low - pressure ammonium carbamate solution , bringing about the cold crystallization of the low - pressure carbamate , cavitation erosion of the carbamate pump , and a decrease in decomposition of the carbamate in the rectification column , thereby impairing safety in production
摘要生产负荷提高后，精馏塔带液严重，使低压甲铵液中的尿素含量增加，引起低压甲按冷凝器结晶、甲铵泵气性、精馏塔甲按分解率下降等现象，严重影响安全生产。
