The sulfur recovery unit of Henan Jindadi Chemical Co., Ltd. 450,000 tons/year synthetic ammonia relocation and transformation project successfully started
The sulfur recovery device of Henan Jindadi Chemical Co., Ltd. 450,000 tons/year synthetic ammonia relocation and transformation project designed by our company is a supporting device for the 450,000 tons of synthetic ammonia in the second phase of Henan Jindadi Chemical. The device was successfully started on October 9, 2019. The operation was stable, producing high-quality solid sulphur and reaching the designed capacity that month.
The sulfur recovery device is two sets of sulfur recovery devices with an annual output of about 5,000 tons of sulfur. The sulfur production part adopts the Claus+ hydrogenation reduction and selective sulfur oxidation recovery process of high-temperature thermal reaction in the sulfur furnace and two-stage low-temperature catalytic reaction. The annual operating time is 8000 hours. The sulphur production part is divided into two series, the single series is designed according to 5000 tons/year, and the design operation flexibility is 30-110%. This project is the first application of selective oxidation process in the field of sulfur recovery in three-dimensional engineering.
