SCIENTIFIC AND ENGINEERING BASE, DEVELOPMENT AND PRODUCTION EXPERIENCE OF «CRYOGENMASH» — IMPROVEMENT LNG-EQUIPMENТ

Abstract

 Efficient and reliable LNG-installations are manufactured by company «Cryogenmash» — leader of Russian cryogenic engineering. In the small productivity installations is used a simple refrigeration cycle of high pressure liquefied natural gas. In them external cooling are carried out and ejectors are used instead of throttle. For more than ten of such LNG-installations to obtain 1,5; 2,5 and 3 t/h of product by company was supplied to China. The specific consumption of energy in them — 0,616 ... 0,753 kWh/kg of LNG. At the LNG installations of average production capacity the company intends to use for natural gas liquefaction the effective external nitrogen cooling cycles with several turbo-expander-compressor units. The сompany has developed LNG installations of average capacity to obtain from 7 to 100 t/h of LNG. The specific consumption of the energy in them is expected to be 0,45 - 0,49 kWh/kg of LNG. The company manufactures efficient cryogenic equipment for distribution infrastructure and using LNG. These include the LNG storage reservoirs with capacity from 5 to 250 m3, semitrailer — a cistern with capacity of 30 m3 of LNG. The company has enough scientific and engineering and manufacturing base for production of modern cryogenic equipment intended for implementation it in the different LNG technologies.
