Abstract:

The owner scheme of KAILASHTILLA project has two problems resulted in resources waste，low C₃，C₄ recovery ratio of NGL and unstable condensate oil. One is too many heavy components in stable gas，and the other is excessive stable gas as flared fuel gas. For resolve these problems，a new scheme including a stable gas compressor system is proposed and simulated by PRO/Ⅱ software. The stable gas is fractionated into part of NGL and dry gas with the help of the stable gas compressor system，with which the problems of stable gas are resolved and the recovery ratio of products is improved. Besides，economic analysis is performed based on the comparison of the proposed scheme with the owner scheme from both energy consumption and production rate. The profit of the proposed scheme is higher than the owner scheme with about 38.32 million RMB per year.
