High-pressured gas dewatering installation
High-pressured gas dewatering installation of adsorption type with moisture-laden adsorbent regeneration designed for deep (to a residual moisture content of 0,009 g/m3) drying of the compressed to high pressure (about 250 kgf/cm2) natural gas. Regeneration of the adsorbent is made with dried and heated injection gas at the inlet pressure. Gas extraction for recovery does not exceed 5% of the plant performance. Gas dewatering installation provides the work of a station without generation of hydrate formations at environmental temperatures up to -30°C.
Place of dewatering installation — after the last compressor stage. Installation is equipped with loop line of gas supply through adsorber, which is controlled manually. Time of dewatering half cycle is not more than 8 hours.
Dewatering control is automatic.
Safety valves are installed in dewatering installation on the lines of compressed and recycle gas.
By agreement with the orderer, installation can be equipped with humidity meter with output of indications on the control desk in control room*.
