Abstract

The compressor (C-100) located in the Hydrobon & Platforming I unit is designed to meet the need for recycled gas to keep the H2/HC ratio optimal in the Platforming I section and minimise the rate of coke formation in the reactor. In addition, a Compressor (C-100) is used during the start-up process of the Platforming I unit to maximise LPG production. However, PT X is currently focusing on reformatting production to meet market demand, which prompts considering commissioning a Compressor (C-100) for energy efficiency and cost savings. The shutdown of the previous compressor, which consumed 2400 kWh per day at an annual electricity cost of IDR 8,347,273,344.00, has significantly reduced energy consumption. However, other operational costs, such as maintenance and lube oil make-up, remained during the period, with annual expenses of IDR 440,036,956.00 and IDR 48,741,977.00, respectively. In addition, energy from alternative sources such as steam and cooling water also increased to maintain process performance, with total annual operating costs of IDR 56,256,360,451.20 and IDR 179,789,760.00, respectively. Overall, the operating cost of the Compressor (C-100), which includes electricity, make-up lube oil, and maintenance, totalled IDR 8,836,052,276.80 each year. A review of the compressor operation could provide a solution for cost optimisation and energy efficiency for the company.
