Here HJ wants to give some suggestions to the entrepreneurs ：
1．The new project enterprises want to invest nitric acid, nitrate, and nitro-compound fertilizer should be follow the demand of the market. Enterprises couldn’t have blind and conformity thinking just following the other company’s investment. Enterprises should have own specialty but it should not only focus on its own scale big or not. Investing the new project should consider the actual con-dition and compare the similar products with the competitors’ . The key point is what advantages your enterprises have: is it the advantage of the ingredients; the advantages of the marketing; the advantages of the technology or the advantages of the management .these questions are the pro-blems that enterprises should attach the importance on.
2. If enterprises has decided to invest nitric acid, nitrate, nitro-compound fertilizer these pro-jects, we strongly recommend enterprises should choose the advanced technical process and well designing institute, well equipment manufactory, trustable construction organization.Enterprise can benefit a lot from the technology advance; project design optimization also can help saving inve-sting and running fee; good equipment manufactory and trustable construction organization can give the guarantee of the construction quality .These are all the key points ensuring the device can run safely ,stably and economically in a long time .
3. We recommend several productions to enterprises which have relative market potential:
（1）Dilute nitric acid (concentration 65%-68%) disintegrates phosphate ore then the process uses freezing method producing nitric phosphate and by product is amide lime nitrate 【5Ca(N03)2•NH4NO3•10H2O】.The product and process is the development direction of the nitro compound fertilizer industry all over the world.
（2）Dilute nitric acid disintegrates limestone that produces crystallographic calcium nitrate【Ca(NO3)2•4H2O】and larger particles ammonization calcium nitrate【5Ca(N03)2 •NH4NO3•10H2O】.Namely, “Two calcium” products. The annual capacity is 100000-200000 tons for large particles ammonization calcium nitrate pro-ducts. We suggest owner to use drum fluidized bed granulation. HJ .Company could provide the process patented technology of drum fluidized bed granulation.
（3）Potassium nitrate crystallization of potassium nitrate and large particles. From econo-mics point of view, mainland enterprises are suitable to adopt the double decomposition method, because the energy consumption indexes are much lower than ion exchange method and the by-product is ammonium chloride（contains K2O 2-5%）could serve as feedstock for the production of compound fertilizer. From the market point of view, with the development of domestic nitro com-pound fertilizer, the national market of agricultural potassium nitrate will gradually expand . We suggest owner to adopt drum fluidized bed granulation for large granular potassium Nitrate. HJ Company could provide the process patented technology of drum fluidized bed granulation.
（4）Sodium nitrate and sodium nitrite products. Namely , “two sodium” products . In recent year, the new domestic projects were not too many and productivity was relatively seldom. Though the marginal profit is small, these two products have a certain market. Manufacturing enterprises still have a certain amount of profits from this investment . These products are also the main products of some small enterprises.
（5）Large granular ammonium nitrate products.The product does not exist in china but has a certain potential in the domestic and foreign markets. Interiorly, large granular ammonium nitrate products will gradually replace the crystallization of ammonium nitrate. Large granular ammonium nitrate has got a larger market over-seas. HJ could provide large granular ammonium nitrate drum fluidized bed granulat-ion of proprietary technology for.
In brief, these are some advices from HJ. If you want to know furtherly, we welcome you to contact us and require.
