In June 2018, after multiple rounds of inspections, comparisons, and in-depth evaluations, Jiuquan Iron and Steel (Group) Co., Ltd. decided to adopt the "Seven-effect Two-stage Separate-type Falling Film Evaporator" independently developed by Henan Jiuye Chemical Equipment Co., Ltd., which is at the international leading level. This evaporator was used in the project of upgrading and increasing the production capacity by 2 million tons at the Alpart Alumina Plant of Jiuquan Iron and Steel (Group) Co., Ltd. in Jamaica. The signing of this cooperation agreement between the two parties marks that the upgrading and production increase project of the alumina plant of Jiuquan Iron and Steel (Group) Co., Ltd. in Jamaica has entered the fast lane. At the same time, it also means that this large-scale equipment, the seven-effect tube falling film evaporator, has gone abroad for the first time and traveled across the ocean. Since the "Seven-effect Two-stage Separate-type Falling Film Evaporator" developed by Henan Jiuye Chemical Equipment Co., Ltd. obtained the national patent in 2012 and passed the scientific and technological appraisal organized by the China Nonferrous Metals Industry Association in 2013, it has attracted the attention of major domestic aluminum industry groups. Over the past few years, multiple sets of seven-effect evaporators with different production capacities have been successfully promoted and applied in China. Henan Jiuye Chemical Equipment Co., Ltd. highly values and attaches great importance to the project of two sets of 300t/h evaporators signed with Jiuquan Iron and Steel (Group) Co., Ltd. The company carefully checks each link, including design, raw material procurement, and production and manufacturing. It goes all out to create a high-quality project and contribute to the upgrading, transformation, and production increase of the Alpart Alumina Plant of Jiuquan Iron and Steel (Group) Co., Ltd. in Jamaica. For a good enterprise to develop rapidly and steadily in the fierce market competition, it must carry out independent innovation and possess its own core technologies. Henan Jiuye Chemical Equipment Co., Ltd. has been moving forward steadily, step by step, striving and exploring. Staying true to its original aspiration and forging ahead, it has overcome numerous technical challenges and obtained 11 patented technologies in the field of evaporators. In the new era, on the new journey, with a new outlook, it has always been on the path of innovation and striving for strength. It firmly believes that: "A time will come to ride the wind and cleave the waves; I'll set my cloud-like sail to cross the sea which raves."
