I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

result of this calculation is a starting requirement of 576.5 tons of iron ore fines entering the system to ensure 400 semi-processed tons enter the 2nd reactor. The 356.4 tons of outflow from the 2nd reactor (400 x 1- yield loss x 1- mass loss) is the input to the next step. We continued to take the outflow from each step and multiply by (1- the yield loss) to arrive at the final value of 321.5 tons of Hot Briquetted Iron (HBI)‚ per cycle. The number of cycles in a year was determined

Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education
