摘要

以某电厂氨站输氨管道内沉积物为研究对象

采用离子色谱、电感耦合等离子光谱、热重-红外联用技术、固体红外和X射线衍射对其物化性质进行表征分析。结果表明:该电厂氨站输氨管道内沉积物主要由水溶性物质氨基甲酸铵、碳酸氢氨、碳酸铵和水不溶物水铁矿构成;空气是输氨管道沉积物生成的直接原因

空气中CO_2与液氨反应生成氨基甲酸铵

腐蚀金属管道

生成水铁矿(Fe_5HO_8·4H_2O)

堵塞输氨管道。

Abstract

The deposition in ammonia transportation pipeline of ammonia station in a power plant was collected.The physicochemical properties of the sample was characterized by several ways

like the ion chromatography

inductively coupled plasma emission spectrometry(ICP)

thermo-gravimetric and Fouriertransform infrared spectroscopy coupled technology(TG-IR)

solid Fourier-transform infrared spectroscopy(IR)and X-ray diffraction(XRD).The results show that

the deposition in ammonia transportation pipeline of ammonia station is mainly composed of ammonium carbamate

ammonium bicarbonate

ammonium carbonate

and ferrihydrite.The air was the direct reason for the formation of deposition in the ammonia transportation pipelines.The ammonium carbamate

which was generated by the reaction between carbon dioxide and liquid ammonia

caused the corrosion(with formation of ferrihydrite

Fe_5HO_8 ·4H_2O)and blocked the carbon steel pipelines.
