Whose urea plant hydrolysis system is from Stamicarbon?
Thread Content
I would like to ask which of the Haiyou companies uses a Stamicarbon hydrolysis system for its urea production process. How is it performing? Can the required parameters be met? What is the maximum processing capacity? Could you leave your contact information so I can visit and have a discussion?
The medium-pressure hydrolysis technology provided by our company is basically similar to that of Stamicarbon; it has been deployed in over 30 facilities across the country, and all the design specifications have been fully met. For inquiries, please contact wangyq1971@163.com
It’s better to go and check out Orchid Coal Chemicals (Jincheng Dahuahua). I heard that their processing capacity has reached 35 m3/h, with NH3 and Ur levels both below 3 ppm.
Our company uses the Stamicarbon process; the reaction tower and hydrolysis tower are vertical in design, with a processing capacity of 78 T/h. The designed output level is 1 ppm of ammonia and urea, and the conductivity during operation is around 10
Friend upstairs, may I ask which factory it is from? Has the unit been started up? How is the deep hydrolysis operation going?
:) Ours uses the Stamicarbon process, with a hydrolysis temperature of 200 degrees; the levels of NH3 and urea in the wastewater are both below 5PPM
The factory is on the 6th floor; how can the results be so good! ! !
It also depends on the processing capacity of the equipment. Back at Wushihua Petrochemical, with an annual production of 600,000 tons, the processing rate could reach 48–60 m3/h; the levels of NH3 and Ur were both below 3 ppm, and the conductivity was less than 10 us. In this current company, with an annual production of 400,000 tons, reaching a processing rate of 37 m3/h already presents difficulties. The levels of NH3 and Ur are still below 5 ppm, but the conductivity fails to meet the required standards. Once formaldehyde is added, the conductivity rises above 30, making it impossible to utilize the water – it needs to be treated again before it can be used in the circulating water system
The desorption-hydrolysis unit is a systematic project, and its operational results are related to every component within the system. During design or modification, it is necessary not only to have clear technical exchanges with the service providers but also to conduct on-site inspections of their performance, understand in detail the conditions at the user’s site, and consider carefully the differences between those conditions and those of one’s own unit before making a decision.
Reply to 8# 99155863: I wonder if the addition of formaldehyde will affect the conductivity during desorption and hydrolysis? What principle? Please give me some advice.
