Hydroprocessing Cycle Data Review

Screens current hydrocracker / hydrotreater operation against cycle targets and flags WABT, product sulfur, H2 consumption, and conversion performance.

Method: LHSV = feed volumetric rate ÷ reactor volume (expressed per hour, 1 BPD = 0.234 ft³/hr). Conversion ≈ 1 − product T50/feed T50. Pass/fail screens check WABT vs target, H2 partial pressure above minimum, and product sulfur below spec.
