Group of Companies “LENNIIHIMMASH”

Group of Companies “LENNIIHIMMASH”

LENNIIHIMMASH Group is a western-type company performing a full range of works related to execution of EPC/EPCM contracts.

The company is vastly experienced in the development of projects both for complex hydrocarbon gas conditioning systems, as well as deep refining lines for natural and associated petroleum gas, and complex design of gas processing plants with recovery of a wide range of market products like LPG, propane-butane mix, hydrocarbons, ethane and helium.

The basis for successful operation of our lines is highly efficient technology developed by us, which is based on the application of inner refrigeration cycles at the main gas stream with the usage of turbo expanding assembly mostly without propane coolers and very low power consumption up to 0.5 MW, as well as special heat exchangers (with helical tubes) that enable to get up to 10-15 thousand m2 of the surface at one unit, patented by our institute. Recovery rate of C2+ is 99,5%.

High quality of works is ensured by PDMS three-dimensional design system, implemented in the institute. It provides an opportunity for all the company’s divisions to carry out engineering simultaneously in the same model, which not only eliminates errors, but also significantly decreases timeframe of engineering, as well as construction and installation works. LENNIIHIMMASH Group comprises all the specific engineering departments and develops all the main sections of design and estimate documentation, except for some specialized ones.

LENNIIHIMMASH Group has its own equipment design department, which develops all non-standard equipment, as well as procurement division carrying out a range of works on support, inspection and supply of the equipment, including certification and obtaining Rostekhnadzor permits for equipment usage.

The company has successfully implemented and certified a quality management system complying with ISO 9001 – 2008 standard.
