Oxygen Removal - Natural Gas
PSB designs and manufactures oxygen removal packaged skids for many industries. PSB employs precious metal catalyst operating at elevated temperatures.
Features:
RNG facilities requiring lower Oxygen to meet natural gas pipeline tariff.
Pipeline tariffs can range from 0.1% (1,000 pmv) down to < 5 ppmv.
PSB Deoxo Packages regularly produce < 1.0 ppmv Exit O2!
Packaged units include all necessary ancillary equipment.
H2S guard bed
Economizer
Air/Water cooled coolers
Moisture knock out and auto drain
TSA/Desiccant dryer to remove water vapor
Sources:
- Landfill/ Digester/ Wastewater Treatment Plant
- Flow: 100 to 5,000 scfm
- Pressure: 80 to ~800 psig
- Oxygen inlet: 0.1 to 1.5% vol standard range 1.5% to 2.8% vol optional
Standard Designs Available:
200 MWP (~ 80 - 180 psig operating)
500 MWP (~ 200 - 450 psig operating)
875 MWP (~ 500 - 800 psig operating)
Biogas (Landfill / Digester / Waste Water / Coal bed, etc.) is often contaminated with Oxygen and this can make the gas unacceptable to the product pipeline owner. PSB Methane Deoxo and Dryer Skids are an ideal system for removing oxygen and moisture from the pretreated methane gas.
Each unit is conservatively sized to remove O2 and H2O and are designed based on the gas composition, flow rate, temperature and pressure. An optional H2S guard bed will protect the catalyst vessel. The Oxygen is then removed from the methane gas stream through a catalytic reactor and excess heat is removed and then moisture removed with a dual tower desiccant dryer.
Typical concentration range of O2 inlet is 0.1% to 2.5% volume.
PSB’s Methane Deoxo will purify the stream to less than 0.1% or even less than 5 ppmv O2.
PSB’s Dual tower desiccant dryers remove moisture to less than 7 lb/MMSCF and more typically less than 4 lb/MMSCF.
