Pioneer in the Nitric Acid Industry & Carbon Neutrality Expert in the Chemical Industry
As a core component in the preparation of essential industrial chemicals such as nitric acid, caprolactam, and hydroxylamine, the ammonia oxidation furnace has always been a speciality of Oschatz Global. In 1937, Oschatz Global produced the first LaMont boiler for nitric acid production. To date, Oschatz Global has designed and manufactured over 300 ammonia oxidation furnaces and their supporting equipment for clients in 29 countries worldwide. Since delivering the first ammonia oxidation furnace to Chinese users in 1974, Oschatz Global has successfully supplied more than 40 ammonia oxidation furnaces in China.
The “LaMont” ammonia oxidation furnace produced by Oschatz Global features a coil layout, with the design of the superheated section effectively minimizing direct exposure to high-temperature radiation. The evaporation section utilizes forced circulation and absorbs some heat from the process gas, which helps delay material ageing. This design addresses the issue present in the “Babcock” furnace, where the vertical elbow experiences significant thermal stress, a problem that has been resolved in the market. Additionally, it prevents erosion and wear of the pipe wall.
During the production process, ammonia and oxygen are catalysed through a platinum mesh, resulting in a nitric oxide mixture with a temperature of up to 950°C. According to the specific requirements of the process, the gas mixture will be cooled to between 180 and 500 °C after waste heat recovery. At this time, a large amount of waste heat will provide users with huge volumes of stable, high-quality steam through the unique design of Oschatz Global.
The ammonia oxidation furnace developed by Oschatz Global has the following characteristics:
- The furnace head is equipped with a proprietary feedstock gas intake distributor to ensure uniform distribution of ammonia air mixture.
- The heat recovery section of a self-developed customised coil effectively recovers waste heat and produces more steam that meets the requirements with high efficiency.
- The industry-leading proprietary steam water cycle calculation greatly reduces the boiler feed water circulation ratio, thereby saving operating costs.
- The specially designed platinum mesh support device maximises the service life of the catalyst basket.
- The design of the coupling box outside the cylinder will provide great convenience for maintenance.
- With the use of high-quality materials and strict quality control, the operation stability and service life of our products have been greatly improved.
Waste gas, liquid and solid mill-incineration system
For energy-intensive industries such as chemicals, the efficient use of energy and the conservation of valuable resources are of great importance. Since the 1990s, Oschatz Global has designed and built dozens of waste gas and waste heat incineration plants around the world. The service targets include acrylic acid, maleic anhydride, epichlorohydrin, tetrahydrobaric acid, MDI/TDI, PO/SM, MMA, and other devices.
The incineration plants developed by Oschatz Global has the following characteristics:
- The integrated membrane-type incineration plant with a cooling wall can produce more steam for the treatment of various kinds of high-caloric-value waste, with a high return on investment.
- The integrated membrane-type incineration plant with a cooling wall has a long refractory life and a high system online rate for treating saline waste liquid.
- The integrated membrane-type incineration plant with a cooling wall has a vertical layout and occupies a small area.
- Oschatz Global supplies customised designs according to customer requirements. The equipment can incinerate all kinds of waste gas, liquid waste, wastewater and solid waste at the same time
- The incineration system provided by Oschatz Global has low energy consumption, high heat recovery efficiency and good comprehensive economic benefits.
