Evaluasi Desain Piping System Wet Scrubber Untuk Pengendalian Partikulat Pada Pabrik Gula Candi Baru Sidoarjo
Abstract - Boiler flue gas (flue gas) from the chimney produced from burning fuel also causes air pollution. Exhaust gases caused by combustion may contain materials that are harmful to the environment. Wet scrubber technology is a tool used to control air pollution and remove some harmful particles or gases from the industrial exhaust system of Candi Baru Sidoarjo Sugar Factory. In this work method, the piping system design is suitable for the needs of the wet scrubber, which includes piperouted 3D designs and isometric drawings, as well as piping layout designs. The pipe size used (6 , 4”, 3½” , 2½”) for the main pipe, then the size (4”, 3”, 1½”) for the branch pipe. Based on the calculation of the total head manually, the value is 63,410 m and for the pipeflow expert software calculation, the value is 66,110 m with an error percentage value of 4.08%, the pump power used is 20.65 kW for manual calculations and for pipeflow expert software calculations. obtained a value of 21.97 kW with an error percentage value of 6.01%. Then we get the Spiral Jet Nozzle Standard Angle Spray nozzle type. Pump selection using a selection chart and the use of the EBARA 150x100 FS4NA pump was obtained. The results of the efficiency of particulate removal with a water discharge of 90 m^3/h which is able to remove particles with a diameter of less than 5?m and has reached an efficiency target of 90%, the wet scrubber design has met the operating criteria. With an estimated material and manpower cost of Rp. 402.421.116.00.
