When the pressure is higher than the dew point, the system of condensate gas is gas phase, so the theory model of cavern solution should be use to compute gas adsorption.
当体系压力在露点压力以上时，凝析气体系为气态，应采用空穴溶液理论模型计算气体吸附。
Gas injection may make dew point of condensate gas increase. The long-core experiments show that the higher the pressure upkeep is, the higher condensate oil recovery is.
注气可使凝析气露点有所升高，长岩心实验表明保持压力越高凝析油采收率越高。
The principle of production of low-dew-point nitrogen by pressure swing adsorption(PSA) was described, and the application in the manufacture of silicone rubber was introduced.
介绍了变压吸附法制低露点氮气的基本原理及在热硫化硅橡胶生胶生产中的应用。
