Analisis Unjuk Kerja Kompresor Sentrifugal Pada Unit Flare Gas Recovery PT. Arun NGL
Abstract: PT.
Arun NGL has made various efforts torecover losses of energy and water
resources during the production process. One of the main focuses for energy
conservation is flare gas recovery unit. The flare gas recovery system proposed
is skid-mounted type. The primary equipments consists of two compressors that
compress the gas from the flare header gas upstream liquid seal drum. The gas
is then cooled for reuse in the fuel gas system. The flare gas compressor often
experience surge problem due to compressor operating at low flow so that the
pressure decreased dramatically while compressor head system stays at high
pressure. The compressor playsan important role in generating high-pressure
fuel gas. If the compressor is not able to produce enough pressure as required,
the production of fuel gas will be disrupted.This analisis focused on the
calculation the compressor performance, head, capacity efficiency, and
compressor power. Based on the analisys, it is obtained that the flow capacity
is 3500 m3/hr, head compressor is 5700 kJ/kg, and the compressor power is 9000
kW. The results show that the operating condition is still whitin the surge
limitation.
