Production Statistics of Zhongyuan Dahua from January to March China Chemical Industry News 2009-4-13 Since Zhongyuan Dahua and Yongmei Group, Coking Coal Group, Hemei Group, and Henan Gas Group jointly established Henan Coal and Chemical Industry Group, they have relied on the advantages of the large group to do everything possible to organize safe, stable and high-load production. In the first three months of this year, the product output and efficiency of Zhongyuan Dahua Company of Henan Coal Chemical Group increased significantly year-on-year. In the first three months of this year, the company produced a total of 65,000 tons of synthetic ammonia, 108,800 tons of urea, 6,634 tons of hydrogen peroxide, and 8,348 tons of compound fertilizer, representing year-on-year increases of 128%, 145%, 14%, and 18% respectively. ； The cumulative total industrial output value was 309 million yuan, a year-on-year increase of 94%. After joining the large group, the company carried out institutional innovation and integrated internal resources to establish Puyang Guolong Logistics Company and Puyang Zhongyuan Dahua Maintenance Engineering Company. It has also increased the coordination of natural gas supply, transformed some natural gas supply pipelines, and realized multi-channel gas supply. Since the beginning of this year, natural gas supply has increased by 34.6 million cubic meters year-on-year, creating conditions for better completion of production tasks. At the same time, the company pays close attention to tapping potential and reducing consumption, and insists on settling accounts and promoting production. For example, in response to the problems of difficult urea water balance and high steam consumption, the company took measures to stabilize the operation of the urea unit, reduce the return flow of ammonia water, and effectively reduce steam consumption. Since the beginning of this year, the cumulative comprehensive gas consumption of synthetic ammonia has been 1,108 standard cubic meters, a cumulative decrease of 199 standard cubic meters compared with the previous year. ； The cumulative steam consumption per unit of urea was 1,999 kilograms, a cumulative decrease of 329 kilograms compared with the previous year.
What does the moderator mean by "For example, in response to the problems of difficult urea water balance and high steam consumption, the company took measures to stabilize the operation of the urea unit, reducing the return flow of ammonia water, and effectively reducing the steam consumption." What does the return flow of ammonia water mean? The process management and operation level of large-scale urea plants should be relatively high. Will there be difficulties in water balance? Is the load too high?
Is it the fertilizer factory in Puyang? I've been to that fertilizer plant, and the urea plant is the same as ours, even with the same serial number. We also have the problem you mentioned, that is, water imbalance and high steam consumption. Can you give us a detailed introduction on how you solved it?
I don’t know what the composition of the natural gas in Zhongyuan Field is, but the consumption of 1108NM3/TNH3 seems to be much higher. The steam consumption of Zhongyuan Dahua is 1999Kg/Ur, which is unacceptable. The device cannot be whitened.
Zhongyuan Dahua is a Sneim process. Is the cause of the water imbalance in the system related to the hydrolysis-desorption system?
Does anyone know the specific steps for water balance? Thank you all?
Brother, do you have any new news? This kind of old sesame and rotten millet information is so disappointing.
Is the "difficulty in balancing urea and water" mentioned by the poster related to triamine coproduction? As the water balance of the urea device itself, there shouldn't be any problem, right?
