Design And Integration Test Of Pilot Scale Production Of HTPB By Continuous Process

This paper is adesignof a reactor HTPB pilot scale manufacturing process. HTPB designed products have the characteristics of an average molecular weight of 2500-5000 g/mol, the dominant structure of 1,4 -HTPB, with a production capacity of 2 tons per year. Process HTPB production mechanism using free radical polymerization method with hydrogen peroxide catalyst and solvent alcohol.
Design is calculated base on production capacity of 2 tons per year and 40 % conversion. The process principle is:raw materials butadiene is fed into the reactor at a temperature of 180 °C and a pressure of 300 psi. H2O2 catalyst material introduced into the reactor with a flow rate of 0-100 mL per minute at a temperature of 170 oC. Technical ethanol solvent fed to the reactor at a flowrate 0-100 mL per minute at a temperature of 180 °C and a pressure of 300 psi. The reactor type is a reactor pipe flow reactor. Reaction products from the reactor is then cooled and separated from other solvents by solvent extraction. Butadiene reresidue and ethanol is separated from the products by distillation, and then fed back into the reactor.
Design has acquired production equipment systems that support continuous HTPB. Simulation results indicate that the program HYSIS fluid flow every pipe in accordance with the desired and demonstrate appropriate products. Results of testing equipment that has been developed and integrated show that HTPB can be produced with a capacity of 2 tons per year and it worked fine. HTPB test results showed that the average molecular weight of 2500-5000 g/mol with the dominant structure is 1,4-HTPB (60%). Catalyst reacts completely exhausted.
