Several companies such as Luxi Chemical and Jianfeng Chemical produce melamine, but the specific production processes are unknown

【hc360 HuiCong Network’s Chemical Industry Section】Lurgi, the German company renowned for its coal chemical technologies, has, after more than a year of research and evaluation, decided to use the newly developed patented technology for producing melamine via gas-phase quenching at a rate of 144 tons per day – a technology that helps save energy and costs – to build a large-scale facility in Europe. The project is now in the stage of preliminary design. Under the cooperation agreement, Qingda Huaye and Luchi will also jointly develop an ultra-large-scale melamine production technology with a daily output of 240 tons per line. It is reported that as the provider of the patented technology, Qingda Huaye Company delivered the complete set of process documents for this technology to Luchi Company in accordance with the contract requirements, marking a significant breakthrough in China’s use of the vapor quenching method for producing melamine. This technology enables an optimized design for the comprehensive utilization of energy within the system. By employing a number of cutting-edge patented technologies to make significant improvements to process parameters and equipment design, it results in lower energy consumption, a more efficient distribution of energy, no wastewater generation during production, reduced catalyst usage, and high yields per production cycle. The successful development of this technology indicates that China’s melamine production technology is now at the world’s advanced level. Compared with the currently popular gas quenching process, this technology offers advantages such as the ability to operate on a single-production-line basis, which facilitates scale-up; it can reduce the overall energy consumption per ton of product by 42%, save 40% on investment costs; there is no risk of blockages in the equipment, and the annual operation rate can exceed 90%

I’d like to ask everyone! Is a production license required to manufacture melamine?

Which item (or category) in the industrial production license product catalog does it belong to?

Although this product was not found in the list of approved products, a production license is definitely required, as it is impossible to apply for a license to produce industrial products outside the scope of those for which licenses are issued. So it’s just that we haven’t found them; otherwise, wouldn’t all these manufacturing enterprises in the country be producing in violation of regulations?

So if I apply, what forms should I fill out? Even after consulting the Quality Supervision Bureau, it’s not certain; please advise!

The technologies for producing melamine currently in use in China mainly include the European technology and the domestic vapor quenching method. The investment costs for the two processes differ significantly.

Our company has a stock of 12,000 tons of melamine, and our profits have been fairly good this year

Our company has two sets; we’ll make a huge profit after October. With the current bull market for triamines, it will take half a year for the investment to yield half of its value.

Recently, the domestic melamine market has shown a positive trend, with active trading activity. Manufacturers are able to sell their products smoothly andほとんど have no inventory left. Prices are also on the rise. Currently, the ex-factory price of melamine has exceeded 9,000 yuan per ton; most prices range from 9,300 to 9,800 yuan. The price upon delivery is usually between 9,500 and 10,000 yuan, while the market price ranges from 9,600 to 10,500 yuan, with some prices reaching around 11,000 yuan. Compared to late September, most markets saw increases of 1,000–1,300 yuan, with some seeing rises of over 1,500 yuan; this was the period of the greatest increase so far this year. At the same time, the export price of melamine has also increased significantly; currently, the mainstream export price for melamine is between 1,250 and 1,300 dollars per ton, which represents an increase of around 200 dollars per ton compared to late September. Recently, the trend of melamine in the domestic market has been positive, due to three main reasons: first, an increase in demand. Melamine is primarily used in the panel industry. The fourth quarter is a peak period for production in this industry, leading to an increased demand for melamine; currently, many markets such as Guangdong and Guangxi are facing supply shortages. Second, market sentiment has improved significantly. In the first few months of this year, the melamine market showed a relatively weak trend, with many bearish views prevailing and an overall negative market sentiment. However, since September, when the melamine market began to rise, the market sentiment improved significantly. Driven by the mentality of \"buying on rises and avoiding purchases at declines,\" dealers and downstream manufacturers became more enthusiastic about placing orders, leading to active market transactions and a trend of rising prices alongside increasing volumes. Third, it is driven by rising raw material prices. Since the middle to early part of August, the price of urea, the main raw material for melamine, has shown a significant upward trend. Both the ex-factory price and the wholesale price in the market have increased by 150–250 yuan, with some increases reaching around 300 yuan. Currently, the ex-factory price of urea is mostly between 1650–1720 yuan, while the wholesale price in the market is generally between 1680–1820 yuan. The rise in the price of raw material urea has led to higher production costs and higher selling prices for melamine. Given the current situation, the prospects for triamines should remain quite good.

You are referring to the price of triamines there; our company has sold them at 13,000. In the early stages, triamines in the Sandong market were also available in large quantities at 13,000.

Our company’s gas quenching process performed well last year; I’m not sure how it will be this year

Could you all give a brief overview of the scale, investment amount, costs, and market for melamine? Thank you

There are two processes for producing melamine: the calcium carbide process and the urea process. Calcium carbide process: raw materials are CaC2 and N. Urea process: the raw material is urea

Is there a process for producing monohydrazine?
