Annual output of 25000 tons of gas chlorination synthesis of methane chloride process design
Abstract：This topic with annual output of 25000 tons of gas chlorination synthesis of methane chloride process design for a set of meet the requirements of the actual industrial production plan, in order to make the calculation more accurate, we first to methane chloride product properties, USES, the nature of the raw material was carried out based on investigation, after the production scale, production conditions were determined, we investigated at home and abroad the most advanced means of production, ultimately determine the chlorination process to produce synthetic route of methane, the plan is as follows: with natural gas (methane) and chlorine gas as raw material to produce methane chloride, the project layout for the four stages as follows: reaction, absorption section, and refined section and drying section. And we will to the synthetic route of the relevant information accurately business accounting, to ensure the project complete, relevant content includes equipment of material balance and heat balance, the production process, for the arrangement of the equipment layout, finally use AUTOCAD drawing with locus of control process flow diagram, workshop equipment layout (main view, top view) and the main equipment design makes the whole project conforms to the scientific, at the same time put forward concerning production safety, personnel safety, environmental protection, and a series of rules to achieve economic benefit maximization, but at the same time ensure that they meet production standards.
