The design consists of an instruction book and a series of diagram. The instruction book includes:1.Introduction.2.Choice and demonstration of the technological process.3.30000 tons per year 37.2% formaldehyde crafts for production were designde.4.It is not a selecting type of the equipment of calculati and finalizing the design of the standard device.5.Thecraft pipeline calculating.6.Security and abatement of”three waste”.7.Economic initial estimate of technoligy. The diagram include:1.The pipeline of the device and process flow sheet with controlled piot.2.Assemblage chart of the oxidator.3.Plane figure of the de...
