This design uses the acrolein hydration with an annual production capacity of 9 million tons of 1,3-propanediol production workshop. First, the catalytic oxidation of propylene with water vapor and air to produce the propylene aldehyde. And then get the hydration reaction to get the 3-hydroxyl propylaldehyde, the last step of the reaction is the hydrogenation reaction to produce the 1,3-propanediol. The steps of the acrolein hydration is not so complicated, and its technology is more mature. Production costs including equipment considerations are not too large. The difficulty of each link will not be too high. Production efficiency is ideal. Less by-product and toxic intermediates. The whole reaction can be also recycled. Considering the current situation of the country, it is feasible to adopt this method, and this is in line with China's national conditions.

This design has referred to following national standards and the stipulation 

a.Craft system arrangement of equipment design stipulation（HG20570）

b.Production process dangerous material and adverse factor classification and code（GB/T13816-1992）

c.Chemical installment piping arrangement design stipulation (HG/T20549) 

d.Sewage synthesis emissions stipulation（GBJ8978）

e.Commonly used dangerous chemistry classified standard （GB13690-1992）

f.Factory fire protection stipulation（GBJ16-1987）

g.Steeliness pressure vessel（GB150）

h.In pressure vessel chemical mediator model harm and explosion hazard degree classification（HGJ43-1991）

i.Shell type heat interchanger standard（GB151）

Keywords: 1,3-propanediol；Catalytic oxidation reaction；Hydration reaction； Hydrogenation reaction
