Abstract
Sistem udara bertekanan merupakan suatu sistem yang berfungsi untuk menyediakan kebutuhan udara bertekanan pada suatu sistem baik itu untuk kebutuhan industri maupun kebutuhan bidang lain.Pada instalasi sistem udara bertekanan yang digunakan oleh PT Petrokimia Gresik di Fly Ash Pneumatic Conveying System digunaan untuk mensuplai abu terbang atau fly ash yang merupakan produk sisa pembakaran dari batu bara pada boiler PLTU di Petrokimia Gresik.
Kebutuhan udara bertekanan di Unit Batu Bara PT Petrokimia Gresik dipenuhi oleh kompresor jenis oil injected screw dan beberapa peralatan penunjang seperti air receiver,air dryer,dan pressure vessel.Mengingat pentingnya peningkatan kualitas dan penyesuaian kebutuhan pada sistem udara bertekanan ini maka perlu dilakukan perhitungan ulang pada sistem udara bertekanan pada fly ash pneumatic conveying system di PT Petrokimia Gresik.
Dari hasil perhitungan didapatkan kapasitas udara yang dibutuhkan sebesar 98 ft3/min, laju aliran massa material sebesar 13.6325 ton/jam, dan kerugian tekanan yang terjadi sebesar 4511.32 Pa..

Compressed air system is a system that supply the need of compressed air for industrial use or another application.In the installation of compressed air system used by PT Petrokmia Gresik in Fly ash pneumatic conveying system,the fly ash is the by product of the coal combustion in the PT Petrkimia Gresik Power plant boiler that need to be trasferre into the Ash Silo.
The need of compressed air in Coal unit of PT Petrokimia Gresik is fullfilled by oil injeceted screw compressor and some other supporting equipment such as air receiver,air dryer,and pressure vessel.Considering the importance of quality and the need of compressed air in this plant,then it needs to be done the racalculation on the Requirement of compressed air PT Petrokimia Gresik..
From the result of calculation, the capacity of compressor air generated by 98 ft3/min, mass flow rate is 13.6325 ton/jam, and the pressure loss is 4511.32 Pa.
