There's a hero dream behind the diazine。
The hero races to the dawn, but it is the night that makes him. “the path to the nationalization of the diazine is long and difficult, but it is always ahead of the bite.” in this interview, many practitioners have been impressed by the unremitting exploration that chinese companies have carried out in china for decades. Most of them believe that the full-scale nationalization of the americium is moving forward along the path of those who have gone further。
It's been 10 years since the wall broke, and it's hard to pay for the sea。
Silent journey, endless drums
According to experts, the technical routes for the production of diazine consist mainly of acrylic ammonia, acrylic electrolytes, butadiene and acne. Among them, the competitiveness of acrylic ammonia acoustic acid is heavily influenced by feedstock prices and the scale of production of acceleramine is more limited by the origin of the raw material. The process of acrylene electrolytes and butadiene is short, material is low in consumption and product quality, but the latter is less costly and is currently the dominant process。
Li wenjun, a researcher of the chinese federation of petroleum and chemical industries, shared with journalists cases of exploration of the national production of thiram。
Liaoyang petrochemicals, the first to “eat crabs”, introduced foreign technology in the 1970s (the acceleratorization of adipic acid) to build the country's first diazine production unit. However, the plant ceased production in 2002 owing to poor operation and excessive feedstock costs. In august 2015, shandong yunhing chemical technology ltd. Used the acrylic electrolyte dioxin method to complete the first 100,000 tons of domestic acrylic diazine production unit, but the explosion occurred during the material test phase and stopped. In 2018, chongqing ultimate chemical co. Ltd. Built a 500-ton/year acrylene electrolytic dioxin test device, but no further public reports were made。
The horn of national production remains intact. In october 2019, the 50 million tons of americium per year, built by the waco group using the acrylic acceleratorization method, became the first enterprise in the country to achieve the industrialization of acne. In august 2019, work began on the 200,000 tons of neptunium per year by skylight new materials ltd. The project is expected to follow the current global mainstream butadiene approach。
In recent years, the hedimon project has flourished. In 2020, work began on the 50,000 tons of henan gorge molecular materials ltd. (incorporating the swedish adipic acid catalyzine act patent technology) and 200,000 tons per year (phase 50,000 tons per year) of henan madhi anification chemical co. Ltd. (butadiene act). In april of that year, nanjing zhengxi clean energy co. Ltd. And the institute of process engineering of the central college of sciences contracted to develop coal-based diazine technology and build 3,000 tonnes/year demonstration devices。
In the recent past, news of the national production of diazine has spread. Journalists were informed by zhejiang seng seng sing ltd. That the company had completed a test of the diazine project (technical route unknown). On 30 april, the methanol and butadiene-based two-step legal aridium process, developed by dowsk mines equipment technology ltd. In beijing, was evaluated for scientific and technical results through the china chemical information centre. It was revealed that the 500-ton/year mid-test device using the technology had been stabilized and that a ton-grade device was about to be constructed。
It is worth mentioning that on 5 may, the niron 66 new materials project was driven under the banner of the jiangsuyan agrochemical group, ningsharitai science and technology inc. The project can bypass the restriction on the material of the diazine and do not run the path for the preparation of the dichloride。
And the night will be long, and the way will follow, and the fire will smite。
Think calmly, explore the question mark
The project surged, but many experts remained calm。
“the level of technology, the quality of products and the competitiveness of the economy are to be tested for industrial production.” in an interview with a journalist, the vice-president of the union of pic reminded me that “some would say that the past year had been a very good year, but that it had been a special year, when the impact of the epidemic, the `hard container' of sea transport, the disruption of the supply chain, etc. Had caused a sharp rise in product prices, which could not be used as a reference for the normal year. The maturity or success of the project can only be judged rationally when the industrial production unit is functioning properly, the market is back to normal, and it is fully in the face of a level playing field of normality.”
What is the difficulty of industrialization? According to li wenjun, it is a long process of production, a complex system of catalysts, high technical barriers, and very difficult to magnify. In the case of the currently dominant butadiene law, the toxic properties of the raw hydrogen cyanide have been prohibitive for most research institutions, and the development of a core catalytic system based on zero price nickel-thylene coupling has become even more vacant in the country。
Li wenjun suggested that enterprises should make technical route selection and technology magnification risk control treatment. At the same time, new projects need to carefully analyse possible technological risks, safe environmental risks, intellectual property disputes, etc。
“we also note that construction of several americium projects is under way in the country, and that various production technologies are being developed and tested, mostly by enterprises.” according to li wenjun, “this indicates that business is becoming the subject of innovation in this area, with a growing combination of technology and finance and a growing focus on intellectual property protection”
Other experts suggested that macro-level planning should be undertaken to avoid blind investment and expansion。
The men of the mandarin are as iron and teach them to drop water through stone and walk。
Future scenery, forward flag
In the above-mentioned case of the industrialization of diazine, the hua feng group and the sky are of the greatest interest。
“in the face of the adverse situation of foreign blockades and denials, the wa feng group has made a major breakthrough in the development and innovation of the process of catalyzing the aridium dichloride (add) in the legal system and has established and completed a complete industrial chain of benzene-add-add-nylon66.” the vice-president and managing director of chongqing feng chemical co. Ltd., chen eun jian, said that once the issue of whether heptonium had been resolved, there was still a need to resolve the question of whether hepium was good or not competitive。
The relevant director of the company stated that although the technology for production of butadiene and acrylic electrolytes was monopolized by 100 per cent abroad, acrylic ammonia is still a viable option based on a relatively mature technological base, combined with the advantages of its raw materials。
The sky-sakurabutadiene-based diazole project is of greater concern. The chairman of the board of directors told journalists that the first phase of the project would build 200,000 tons of americium per year, about half of which would be self-employed and half of which would be exported. The whole-industry chain design, from the americium to the nylon 66, can adequately counter the risks posed by external market competition at an early stage of technology industrialization。
According to the deputy secretary-general and general manager of china tiantai engineering co. Ltd., who gave a monthly presentation, there are almost no references available under the technology blockade. After more than 10 years of hard work, china's tiantai scientific team has worked hard to develop a successful technology for the production of thiram with autonomous intellectual property rights and has actively promoted industrialization. It is known that the current tsai xianxiri project is well under way and that it is expected to complete the material test in the near future。
“as soon as the installation is completed and delivered successfully, it means that the industry has eaten down even the hardest bones and is of great benefit to the downstream chain.” li wenjun's assessment was that “the parallels of the two technical routes can greatly guarantee the safety of our nylon industrial chain”
The light is on the horizon, and the males look at the dawn and the sun rises in the east。
