Sustainable innovation and leading technology are the key drivers for JET’s continued success. As an industry leader and pioneer of ammonia-based desulfurization JET has protected its intellectual property which includes 9 PCT patents and over 80 Chinese patents, that cover all of the core technologies of ammonia-based desulfurization.
By successfully overcoming the technical barriers of ammonia escape, oxidization, anticorrosion and equipment dependability, and by allowing users to treat flue gas up to the ultra-clean emissions standard, JET has completed over two hundred ammonia desulfurization projects.
