Which company uses the Superclaus process?

Which company uses the Superclaus process? What are the specific process conditions, and what is the performance of this process? How much investment is required to use this process for producing 400,000 tons of synthetic ammonia?
Super Claus also has some successful applications in China; for example, the Yankuang Guizhou project uses the Super Claus process. However, it is currently under construction. The amount of investment required depends on the sulfur content of the coal used – this process does not require a very high concentration of acidic gases; generally, around 40% is sufficient. If the sulfur content is too low, the costs associated with sulfur recovery increase, while if it is too high, the costs related to low-temperature methanol washing rise. Therefore, a sulfur concentration of around 40% is usually chosen for sulfur recovery processes.
The 60 tons/day unit at Sinopec Anqing Refinery is in operation. The 34 tons/day unit at the Quxian Natural Gas Purification Plant, which belongs to the Southwest Branch of China National Petroleum Corporation, is also in operation. The 2 x 26 tons/day units at the Zhongxian Natural Gas Purification Plant, part of the Southwest Branch of China National Petroleum Corporation, are operational as well. The sulfur recovery unit of Yulin’s 600,000 tons/year methanol production project, operated by Yankuang Group, has a capacity of 17 tons/day and is awaiting commissioning. The sulfur recovery unit of Shandong Tengzhou Phoenix’s domestic coal gasification project for the production of various chemical products also exists. Additionally, there is a sulfur recovery unit for the 500,000 tons/year synthetic ammonia production project at the Kaiyang Coal Chemical Industry Base, operated by Yankuang Guizhou Energy Chemical Co., Ltd
Is Super Klaus widely used in China and what are its effects?

Can Super OptiKlaus actually meet the emission standards, I mean around 960? Who can teach me?
Maersk from the Netherlands came to discuss this with us; they said that the sulfur dioxide level in the exhaust gas from Super Claus can only reach around 1800 ppm, and it needs to be reduced by adding air for dilution. It’s not either a very good solution, but this process is simple and easy to operate.
