  The results of a search for two neutrino mode of double K-capture of Xe-124
using a large copper low-background proportional counter are presented. Data
collected during 3220 hours of measurements with 58.6 g of $^{124}$Xe provides
us to a new limit on the half-life of Xe-124 regarding 2K-capture at the level:
T_{1/2} >= 2.0*10^{21} years at a 90\% confidence level.
