Gas dryer
A low-pressure gas dryer is applied for purification and adsorption dehydration of gas at the compressor unit inlet.
Dehydration is intended for application in low-pressure gas lines. Gas dehydration is carried out in a two-cycle system: a dehydration cycle and a regeneration cycle. Regeneration is carried out with the hot air with the aid of a special heating module.
Inlet gas dryer
| Parameter |
Value |
| Mounting location |
Upstream the CU after the inlet filters |
| Max.operating pressure in adsorbers |
1,6 MPa (16 kgf/cm²) |
| Max. flow rate |
3 000 m³/h |
| Moisture content after dehydration |
Max. 0,009 g/nm |
Outlet gas dryer
The high-pressure dryer is applied for dehydration of the highly (~250 kgf/cm2) compressed natural gas. Adsorbent is regenerated by heated gas in a closed loop, with the aid of a vacuum pump.
The dryer mounting point — at the compressor outlet. The gas dryer can be additionally fitted with a hygrometer with readings displayed at the operator station in the control room.
Control of the gas dryer is automated.
