Styrene plant ethylbenzene distillation process technology design
Summary
Styrene is an important basic organic raw materials for the production of plastics and
synthetic rubber, mainly used in the production of polystyrene, ABS, and can also be used
forthe preparation of styrene-butadiene rubber, styrene
- maleic - styrene block copolymer,
unsaturated polyester In addition, production of paints, dyes, synthetic medicine is also an
important raw material. Domestic styrene ethylene economic development, after 2000 to enter
the stage of rapid development and growing market demand, large-scale production has
become the main performance of the market competition the styrene technical aspects of the
increasingly fierce competition, especially abroad, styrene technology from raw materials,
energy consumption, stability, security, operability of the last century has greatly improved and
innovative. As the technical side, the only in-depth understanding of current developments and
changes in order to establish the advantages of a real future technology development,
application and innovation. This article is a styrene plant ethylbenzene distillation process
technology design. Using a liquid alkylated preparation of ethylbenzene, separation of
ethylbenzene in the direct catalytic dehydrogenation process of the technology of the
production of styrene. Theory and technology to complete ethylbenzene distillation unit process
piping and equipment selection design. On the one hand familiar with the design concept of the
technology package of construction projects, on the other hand by checking the results.
Styrene plant ethylene distillation unit high energy consumption, equipment operation and low
efficiency to analyze the feasibility of optimization problem, while by the change project.
