Question 1: What is the impact of the reactor temperature on the installation? Answer: This unit employs a CLAUS sulfur recovery process with ammonia combustion for sampling purposes. The acidic gas entering the reactor contains 5–8% (V) ammonia; if this ammonia is not completely burned in the reactor, ammonium salts will form in the coldest parts of the unit, leading to blockages in the equipment and pipelines. To ensure complete combustion of ammonia in the reactor, it is necessary to maintain the temperature inside the reactor at 1250–1450°C.
The acidic gases entering the reactor contain ammonia; if this ammonia does not burn completely within the reactor, ammonium salts will form in the coldest parts of the equipment, causing blockages in the devices and pipelines. To ensure that the ammonia burns completely in the reactor, it is necessary to maintain a temperature in the reactor chamber above 1250 degrees

This unit employs a CLAUS sulfur recovery process with ammonia combustion for sampling purposes. The acidic gas entering the reaction furnace contains 5–8% (V) ammonia; if this ammonia is not completely burned in the reaction furnace, ammonium salts will form in the coldest parts of the unit, leading to blockages in the equipment and pipelines. To ensure complete combustion of ammonia in the reaction furnace, it is necessary to maintain the temperature inside the furnace at 1250–1450°C.
The furnace temperature must not be lower than 920°C, otherwise the flame will be unstable. The higher the furnace temperature, the higher the conversion rate will be as well; however, an excessively high temperature can affect the service life of the furnace. A temperature of around 1100 degrees is sufficient. The book on petrochemical engineering and technology states that ammonia can decompose at 520 degrees, but our operating procedures specify that a temperature of over 1250 degrees is required for complete decomposition; this is a bit confusing
