Abstract
Acetaldehyde is intermediate products of the petroleum and chemical. Their production methods are the acetylene method, ethanol, straight-chain saturated hydrocarbon oxidation and direct oxidation of ethylene. Direct Oxidation of Ethylene to Acetaldehyde process line and two-step and step. Here the focus of direct oxidation of ethylene by step description of the legal system of the production process of acetaldehyde. Its production process by oxidation, distillation, distillation process component.
The design of the main step in the use of ethylene oxidation of acetaldehyde to reach the designed annual production capacity of 80,000 tons a device the purpose of acetaldehyde. First of all, described the design process of choice (including the response to regeneration, the three distillation section), followed in a given production conditions, for each section for material balance, heat balance, equipment selection, the so towers, heat exchangers, pumps and other equipment in terms of structure and design to determine.
