The Masoneilan 71000‑Series single‑ported, heavy top‑guided control valves feature inherent versatility, rendering them ideally suited for a broad range of heavy‑duty process‑critical applications including crude‑oil refining and gasifier service.
Crude‑oil refining produces residual “bottom‑of‑the‑barrel” fouling‑prone hydrocarbons, which are sent to conversion units such as delayed cokers, visbreakers and flexi‑cokers. These contaminated fluids crystallize and turn highly erosive, creating processing challenges unless downstream quenching is implemented. Comparable difficulties are encountered in crude‑oil upgraders that process tar‑sand‑derived bitumen carrying entrained sand particles.
