sulfosuccinate also has good emulsification, dispersion, washing, wetting and solubilization properties, especially has extremely low stimulating effect on the human body skin and eyes and has superior decontamination ability. Sodium laurylpolyoxyethene (9) octyl sulfosuccinate has a huge amount of improvment than traditional surfactant on perviousness. It is widely used in fields of daily chemical products, coating industry, printing and dyeing, pesticides, mine diggings, paper making, leather, photographic, etc.
Design datum of this design include: (1) Determine the specifications of the raw material. The specification of the AEO-9 is 99.00%, and the moisture content is 1%; The specification of the maleic anhydride is 99.90%; The specification of the octyl alcohol is 99.50%; The specification of the sodium hydroxide solution is 30.00%; The specification of the sodium hydrogen sulfite is 99.00%. (2) Determine the reaction yield. The overall yield is 93.11%, the reaction yield of single esterification reaction is 99.00%, the reaction yield of double esterification reaction is 95.00%, the reaction yield of the neutralization reaction is 100%, the reaction yield of sulfonation reaction is 99.00%. (3) Determine the scale of production. In the design, the scale of production is producing 800 tons sodium laurylpolyoxyethene (9) octyl sulfosuccinate a year. (4) Determine the operating mode. Intermittent process has the advantages of flexible operation, suitable for production of fine chemical products, so this design uses the intermittent operation process. (5) Determine the construction factors. In order to make full use of the equipment, and at the mean while, considering the equipment maintenance and on-off stream situation, the start factor is taken around 0.8, which means the work shop works 300 days a year, and use the work on two shifts system for the operation.
The design principle of this design includes the design requirements and the internal and external constraints, design requirements are: (1) Conform to the product quantity and quality indicators; (2) The economy: in addition to the inpidual circumstances of production device proceed from social benefits of the product, the rest of the device should not only have the profit, and its technical and economic indicators should be competitive, which requires economically using the fund, raw materials, utilities, and human resources; (3) Security: a lot of material in chemical production is inflammable, explosive or toxic. Therefore, the design must fully take various obvious potential dangers into granted, to ensure that the production persons are healthy and safe; (4)
Conform to the state and local governments at all levels of environmental protection laws and regulations, to deal with "three wastes" that are released; (5) the whole system must be operational and controlled, "operational" refers to design can not only meet the requirements of normal operation, but also can meet the requirements of open parking and other unconventional operations; "controlled" means can restrain the influence of external disturbance, system is stable and can be adjusted. External constraint is not changing with project specific situation, which must be in accordance with: (1) the various laws enacted by the government; (2) all kinds of natural laws; (3) safety requirements; (4) resources environment; (5) must be followed in all kinds of standards and specifications; (6) economic requirements such as investment quotas and payback period. Internal constraints include: (1) production technology, technical maturity, the prices and terms of use; (2) materials, raw materials, building materials, the supply of key equipment is difficult or not; (3) personnel, the diathesis and quality. (4) product specification. (5) the specific requirements of the construction unit. (6) the specific conditions of the factory area.
