Integrated solution
Customer request:
Upgrading deethaniser 2/ZOK-1 to increase its capacity by 20% above the design capacity while ensuring that the total mass fraction of methane and ethane in the deethanised condensate does not exceed 0.8%:Spliteks solution:
- Design and engineering
- Calculation and analysis of all column operating modes. The optimal column operating mode was selected. A sophisticated column internals design was proposed and developed to ensure stable column operation at increased capacity. Unique, non-standard feed inlet devices were developed with due regard to the column shell and the arrangement of the internals
- Manufacturing in Serpukhov
- Installation. Complete replacement of the column internals and welded attachments. The duration of the work was reduced from 18 to 7 days. One week after unit start-up, the customer confirmed that the vessel had reached its operating conditions and was producing on-spec product. Following completion of the work, the customer sent letters of appreciation
Result
The equipment was manufactured, delivered and installed ahead of the contractual schedule and in compliance with the technical specification.
Installation was completed in half the contractually stipulated time, for which a letter of appreciation was received.
Following the trial run, a capacity increase of exactly 20% above the design capacity was achieved while ensuring that the total mass fraction of methane and ethane in the deethanised condensate did not exceed 0.8%.
