Abstract

Energy audit is one way to plan for optimizing the supply and use of energyneeded by the industry. Portrait of the use of electrical energy used in Industrysupplied from PT.PLN (Persero) with the power contract for 23000 kVA and POJPower Jatiluhur with installed capacity of 5800 kVA. Especially for electric energysupplied from POJ Power, status of electricity continues to be a contract with themanager of POJ Power Jatiluhur. Based on the results of measurement of powerquality with PQA Hioki 3197 is as described in the previous section, it can beseen that: (a) Load unbalances seen from the voltage and current, (b) Fluctuatingvoltage magnitude at phase R, S and T. Even the voltage at Mill #2 reaches 238V, (c) The power factor is quite good and it ranged from 0.90 to 0.93, (d) TotalHarmonic Distortion (THD) voltage at Mill #2 lower the tolerance limit of 5%,while at Mill #3 exceeds the limit of tolerance (5.8%), (e) Voltage unbalance onMill #2 and Mill #3 below the limit of tolerance (2.5%).Kata kunci: audit, energi, listrik, faktor daya, penghematan, filter harmonik

Abstract

An effect of two different residue for liquefaction of Central Banko coal isdisccused. The residue was obtained from side-stream of refinery plant, whichso-called long residue and short residue solvents. The liquefaction test wascarried out under the reference conditions that have been developed in BPPTcoal liquefaction laboratory, at temperature of 450oC and initial H2 pressure of12MPa for 1 hour. The result shows that the distillate yield, Bottom (BTM) yield,and hydrogen consumption were dependent on the nature of solvent. Shortresidue solvent shown higher reactivity than the long residue. Reaction betweenCentral Banko and Short Residue gave distillate yield higher than the longresidue. Moreover, its BTM yield was also lower than that of long residue solvent.This result confirmed the lower hydrogen consumption for reaction short residueand Central Banko coal compared to that for reaction long residue and CentralBanko. In this study, it also confirmed that the yield of H2O and CO+CO2 weredependent on the material input condition. However, the yield of hydrocarbongases (C1~C4) was mainly affected by de-alkylation in the solvent and coal duringthe reactionKata kunci: residu minyak bumi, proses pencairan batubara, central Banko
