我国自行开发的变换气制碱新工艺有很强的竞争力。但由于其中的主要设备碳酸化塔结构大型化困难，多年来只在小型厂中采用，发展不快。新开发的大型碳酸化塔已在最近投产，该塔克服了传统的索尔维碳酸化塔的缺点，这项技术开发成功将促进变换气制碱技术的发展，增强我国纯碱工业在国际市场上的竞争力。

A new process for soda ash production based on converted gas, developed by China is very competitive in the world. However, it is difficult to manufacture the large size carbonization tower because of its special structure. Therefor the process has only been used in the small soda ash plants for years. Newly developed large size carbonization tower has been put into operation recently. Disadvantage of traditional Solvay technology has been overcome by using this new process. The developed technology will surely promote further progress of soda ahs manufacturing based on converted gas, and hence enhance the competitive capability of China´s soda ash industry on the international market.
