Name of work item "Development of design documentation for glycol dehydration unit construction and technical specifications for connection to existing utilities of the enterprise"
Types of works performed Development of design documentation and passing the Glavgosexpertiza of Russia
Year 2018

Brief work description:

Works on development and preparation of design documentation and engineering survey results for passing the Glavgosexpertiza of Russia of the glycol dehydration unit of LLC LUKOIL-Permnefteorgsintez.

Construction of a new glycol dehydration unit is provided to ensure dehydration of wet recycle gas from the units UNTKR-1 (Train# 1) and UNTKR-2 (Train # 2).

Glycol dehydration unit capacity for wet gas is:

  • Train No. 1 no more than 20,000 Nm3/h;
  • Train No. 2 no more than 15,000 Nm3/h.

The glycol dehydration unit is a self-contained unit designed for dehydration of wet recycle gas to a dew point of minus 40 °C using the glycol absorption method. Triethylene glycol (TEG) is used as a liquid absorber. Wet recycle gas is supplied to the unit with two separate streams from the zeolite drying units of the NTKR-1 and NTKR-2 plants.

The estimated capacity fluctuation of the glycol dehydration unit is 10 ÷ 100%.

Scope of work

  • Review of documentation for the glycol dehydration unit;
  • Tying in of the glycol dehydration unit;
  • Location of modules at the plot plan;
  • Development of heat and gas pipelines diagram;
  • Supplement of the documentation with necessary calculations, equipment, and information to get an approval from the Glavgosexpertiza of Russia;
  • Passing the Glavgosexpertiza of Russia.

Work result

Approval of the main state expert review related to the compliance of the design documentation and results of engineering surveys with the requirements of technical regulations and other established requirements.

Work period

February-July 2018 - Development of design documentation (including special sections)
November 2018 - Approval of the main state expert review (the Glavgosexpertiza of Russia)
