PROCESS DESIGN OF STYRENE BUTADIENE RUBBER WITH ANNUAL OUTPUT OF 50,000 TONS
ABSTRACT
After the the 1950s, SBR develops rapidly. It has become the largest international production of synthetic rubber so far. SBR accounted for more than 80% of total production of Synthetic rubber. The Soviet Union, the United States, Canada and East Germany`s production of the SBR are the largest. In recent years, the United Kingdom, Italy, Germany and China and other countries also started the rapid development of SBR. SBR is common type of rubber, and sometimes it can substitute for natural rubber. Some properties are even better than natural rubber. This is a design for an annual output of 50,000 tons of SBR process. The documents are consisted of design specification and design drawings. In the design of brochures, a brief introduction of the SBR production status, trends, performance and the main purpose of the current SBR, also introduced the two common industrial polymer production methods and make a comparison. It was that the low-temperature emulsion polymerization replaced the polymerization technology production methods. In design process, mass balance and energy balance was calculated according to the request of design specification. Process calculation and model selection was made. At the same time, the safe matters need attention and the management of the three wasters in the process of SBR was stated. The relevant design paper was drawn. The engineering flow diagram and major equipment drawing and the arrangement diagram of work shop were included in design drawing.
