Is it feasible to start a formaldehyde project now?

It is feasible to pursue the formaldehyde project now. Due to its mature production technology, high yield, and high product purity, the methanol oxidation method is currently the widely used raw material route in the global formaldehyde industry. The iron-molybdenum method involves the oxidative dehydrogenation of methanol under conditions of excess air. It operates at low reaction temperatures, around 250–400°C, with a methanol conversion rate of 92–94% and high yields of formaldehyde. This method also offers advantages such as low alcohol content, high product purity, low consumption of methanol as a raw material, and good controllability over the concentration of formaldehyde in the product. Market demand for the product: Formaldehyde is an important organic chemical raw material and one of the basic carbon-based chemicals. It has reactive chemical properties and is prone to polymerization, making it an important intermediate in chemical synthesis. Formaldehyde is primarily used in the production of various synthetic materials such as thermosetting urea-formaldehyde, phenol-formaldehyde, and melamine-formaldehyde resins, as well as polyformaldehyde and vinylon. It is widely applied in many fields including adhesives, coatings, resin plastics, **, dyes, as well as in the pharmaceutical and pesticide industries. Adhesives represent the largest sector for the consumption of formaldehyde, with 60% of global formaldehyde resins being used in adhesives for the wood industry. In 2003, the apparent consumption of formaldehyde in China was 3.09 million tons, primarily due to the commissioning of a number of large-scale formaldehyde production facilities and the increasing demand for downstream products of formaldehyde such as urea-formaldehyde resin, phenol-formaldehyde resin, urotropin, large-grained urea, and acetylene-based chemicals. Overall, after more than forty years of development, the downstream products of formaldehyde in China have developed into a relatively complete range of products as well as a relatively stable market for their consumption. However, downstream products with high demand and good market prospects, such as 1,4-butanediol and polyformaldehyde, are still in the initial stages of production in China due to various constraints, and large-scale industrial production has not yet been established. In the next step, as new application markets for these products and traditional products expand, it will inevitably drive rapid growth in the formaldehyde consumption market. Overall, the domestic formaldehyde consumption market has optimistic prospects for development, with both production and consumption set to maintain a rapid growth rate over the next decade or so. It is initially estimated that the domestic demand for formaldehyde will reach 5.9 million tons per year by 2010, and around 7.8 million tons per year by 2015.

Currently, most formaldehyde production facilities in China use the silver-based process, which involves an oxidation-dehydrogenation reaction under conditions of excess methanol. The reaction temperature is somewhat high, but the concentration of the resulting formaldehyde solution can only reach around 40%. The iron-molybdenum process developed by PDS Corporation also performs well; there are nearly 1.2 million tons of production capacity for this process in China, and it allows for the production of formaldehyde solutions with high concentrations, which can then be used in the subsequent production of polyformaldehyde.

What is the maximum capacity for producing formaldehyde in China? Pestop Company’s iron-molybdenum method… the patent fee for its process package is probably quite low, isn’t it?

Yuntianhua’s third formaldehyde production unit has a capacity of 720 tons per day. Ningbo Wanhua’s plant, with a capacity of 120,000 tons, was built in September 2005; it is planned to be expanded to a capacity of 240,000 tons

Our company also plans to invest in a formaldehyde production facility with an annual capacity of 150,000 tons in Qinghai, as a complement to the urotropine production process. Based on our technical and market research, we will use domestic technology, which is already quite mature in this field. The current maximum capacity for such facilities is 50,000 tons per unit (37% formaldehyde); the figure of 150,000 tons refers to three such units.

The domestic technology involves selling equipment and providing preliminary design and commissioning services; for our 4 sets of equipment capable of producing 50,000 tons per year of formaldehyde, the total contract price, including costs for technology, instrumentation, and automatic control systems, is 13.244 million yuan.

I think it is feasible to pursue the formaldehyde project now. I’m not familiar with the specific process flow. But just look at the current market conditions, and you’ll understand.

At present, the Yinfa method should be able to achieve an annual production of 80,000 tons, while the two production lines I set up at Guangdong Junxin Chemical Co., Ltd. in 2006 were each capable of producing 70,000 tons. For any questions or requests, please contact: Mo Lingqing – 13922071390.

The market is rather sluggish right now; it’s better to wait and see in a few days!
