Energy-efficient technology of hydrogenate hot stabilization

Process Description
Feedstock - unstable hydrogenate of diesel fraction is supplied as a heat transfer medium to heat exchange unit 1 of fractionating column 2, then reduced to a stabilization pressure at the throttling valve 3 and fed to supply zone 4. The upper part of column 2 is cooled when the refrigerant is supplied to the heat exchange elements unit 5. Stabilization vapors are discharged from the top of column 2, and a stable fraction is discharged from the bottom.

Process features

• Low capital investment and operating costs
• Exclusion of watering of the diesel fraction
• Exclusion of fire heating
• High industrial safety

Technical Specification
