Haishi has been the sole source pump supplier for ebullated bed residue hydrocracking since 1967, with more than 80 installed pumps worldwide. The Ebullator pump is defined as critical service and is unspared, so reliability is of utmost importance. The Ebullator pump is subjected to extreme process conditions with high temperature (>400°C, 752°F), high suction pressure (>180 bar, 2610 psi), entrained gas, as well as corrosive and erosive process fluid. Haishi supplies the complete Ebullator pump system, which consists of the Ebullator pump, redundant variable frequency drive, redundant high-pressure oil injection system, and redundant oil conditioning system, as well as installation and start-up supervision.
Hydrocracking reactor centrifugal circulation pump
HS series Ebullated Pump is a circulating pump that provides energy for boiling bed hydrogenation unit and suspended bed hydrogenation unit. The pump adopts a shielded structure, eliminates mechanical seals, reduces leakage points, and improves equipment safety.
The pump casing adopts forgings to bear pressure, the impeller and the motor are coaxial, and the motor is lubricated by an external oil injection system. The lubricating oil pressure is higher than the pump chamber pressure to ensure that the medium does not enter the motor. The thrust bearing is made of special materials, taking into account wear resistance and conductivity to improve safety performance.
