Polyacrylamide (PAM) as an ion exchange resin has been widely applied to a variety of industrial production to the synthesis method restrictions, and polyacrylamide toxic. The discovery and application of polyethylene amines can not only compensate for this defect from polyacrylamide, but also in the same molecular weight, had more alkaline containing amine functional groups. In recent years, the research institutes, universities and research focus on polyethylene amine synthesis and applications.
Polyethylene amine is a nascent new materials in the pharmaceutical, oil exploration, makeup, sewage treatment, paper, bio-pharmaceutical, printing and dyeing and other areas with a wide range of applications. However, due to the current mainstream technology in industrial production costs are high, making the prices never down, which greatly restrict its application and popularization, especially in traditional industries.
This design uses a Hofmann degradation of polyethylene amides prepared without catalyst into the purchase from other companies. According to the literature reference, the design gives the basic components of each step recipes, including alternative specific component, the amount of each component as well as basic specifications.
The design for the production of polyethylene amines main production equipment for the equipment selection and design, and to determine the appropriate technical parameters. Major equipment involved in the production reactor, high slot, filter, vacuum pumps, metering pumps, chillers, deionized water equipment. According to the actual production conditions, providing a selected device and the corresponding manufacturers. Among them, the selection and design of the reactor is
the key.
This design article describes the design of the reactor, include material, kettle cover, stirring, jacket, seal and other options. Realization process in accordance with the conditions, safe, reliable, economical, easy to operate and so on principle.
Combined with the actual selection of the production process and product solutions, at the same time carried out on material and energy balance calculations. The total annual production of the design task of polyvinylamine was 300 tons, according to the formula calculated 70% concentrated sulfuric acid, the annual demand of about 683.280 tons, polyacrylonitrile microsphere annual demand of about 341.440 tons, 12% sodium hypochlorite solution annual demand of 2505.400 tons, 10% sodium hydroxide solution, the annual demand is 1081.940 tons, 3841.200 tons annual demand of 50% sodium hydroxide, 6mol\/L hydrochloric acid for 2.340 tons. This design adopts two parts of production lines, 200 days a year, 10 hours a day of production plan.
According to an annual output of 300 tons of polyethylene amine process design and plant layout design. In this design, using the rectangular double workshop workshop. Plant size (length * width * height) is 60m * 12m * 10m. Rectangular building for the general layout of plant, land saving, convenient equipment arrangement, convenient transportation and entrance, more walls to use natural lighting and ventilation design. And the design of the building height requirements higher, using the double high utilization rate of plant, and the design space for the expansion of production.
This design fully considered the problem of personnel safety and environmental protection. In the production process, production requirements strictly abide by the rules, do the toxicity of protective measures, and often participate in related training, understanding of the relevant information.
