Troubleshooting of HFO Purifier in Cai Lan Port
Purifier is a critical machinery at ship. Troubleshooting and operating performance of purifier is monitored by its operating parameters like oil temperature, back pressure, bowl speed, oil density, throughput etc.
Feed inlet oil temperature should be 98-100 °C for HFO and 80-85 °C for L.O for optimum purification. By increasing temperature, viscosity of oil is reduced which is recommended for better purification.
Density of oil should be suitable for purifier as recommended by the maker. Lower density results in better separation because density difference increases.
RPM of bowl should be as high as possible for higher centrifugal force. Centrifugal force is responsible for separating impurities in centrifuge or purifier. In Alfa Laval purifier, rpm is around 9000.
Troubleshooting is a problem solving skill, in which problems are identified and corrected in a logical and systematic order.Purifier is one of the most important machinery which require proper care and maintenance.
