... for Flow Measurement of Hot Pitch During the Distillation of Coal TarIn one of the world’s largest coal tar refineries, the delivered raw material is distilled to obtain technical oils and aromatics, which serve as valuable basic materials for the dye and pharmaceutical industries.Adverse process conditions and media characteristics make flow measurement of pitches a difficult task. Due to the high solid content of the pitch, orifice plates quickly lose their sharpness, and thus their measuring accuracy. Furthermore, pressure impulse lines are quickly clogged by deposit formation. Due to thermal stress, Coriolis or Vortex flow meters fail prematurely. Flow measurement based on ultrasonic clamp-on procedure using the patented WaveInjector® is a superior solution to this problem. Based on convincing experience in tar distillation, wetted measuring systems in the entire plant are being replaced gradually by the non-intrusive FLUXUS® ultrasonic measuring systems. |
