The oil sludge received by hazardous waste plants comes from mixed sources with widely varying composition; sending it straight to thermal desorption or incineration means high energy use and high disposal cost. Ruituxiang's approach is to put "chemical separation" at the very front: recover the oil first and push down the sludge's oil content, then let the reduced material enter downstream disposal.
Inbound sludge is a mixture of tank-bottom sludge, gathering-line spilled sludge and outsourced sludge; composition varies from batch to batch, making treatment parameters hard to fix.
High-oil material entering thermal desorption or incineration directly means high energy and disposal costs, and the oil is "burned off" along with the rest as well.
First use C50N3 demulsification separation to recover the oil and push down the sludge's oil content, then let the reduced material enter downstream disposal — at the same treatment scale, the downstream load is lower, and the recovered oil creates value as well.
Demulsification separation completes oil-phase recovery and lowers the sludge's oil content, reducing the material — the downstream units receive a "lighter" feed.
The reduced material enters the downstream disposal steps; at the same treatment scale the load is lower and the system runs under less pressure.
The scheme covers feed analysis, chemical dosing, equipment integration and performance verification.
The core of front-end separation: demulsification separation recovers the oil and lowers the oil content.
