Our Products

Biogas purification with membrane technology - achieving the highest possible methane yield through membranes with high separation efficiency.

At the core of our biogas upgrading system lies membrane technology. In addition to biogas upgrading, OPM can also provide technology for landfill gas upgrading. Biogas upgrading makes use of membrane technology whereas landfill gas upgrading makes use of membrane technology in combination with PSA technology. All upgrading systems benefit from the add-on of a CO2 Liquefaction technology. This enhances CO2 recovery, further improving the Carbon intensity (CI) score.

* OPM Straw-oriented Pellet Mills
Combine milling and pelletizing, suitable for 30% moisture of raw wheat straws, paddy straws, etc.
Reduce size of straws from 30-50mm to 2-3mm, biogas harvest will be arised by 11%.
* OPM Powerful Steam Explosion Reactor
Shorten the fermentation time of raw biomass from 28 days to 3-7 days, the scale of investment of AD tank can be reduced by 90%, only 10% of investment of existing AD tank.
* OPM Three stages of Membrane biogas upgrading plants
Combine H2S clean and biogas purification units into 40ft container as mobile unit, C02 content of final biogas output will be less than 2%.

• Low Speed of Electric motor
High Torque from low speed will make sure good quality of pellets
• External Cooling Tower make sure the long operation time each day (occassionally, 24/7 will be acceptable. )  
• Helical Gear box  
Std of Accuracy of CNC machining same as Wind turbine gear box Grade 6, less than 0.8μm  

• Fully surrounded air will cool down the ring die and lower down the ash inside pellets. 

Advantage of OPM Steam Explosion

* The pretreated straw is in the form of a slurry that is completely miscible with water, eliminating stratification and floating phenomena, and smoothly realizing the fluidized transportation and fermentation of pure straw;

* When the temperature of the exploded material is lower than 50℃, it can be directly put into fermentation; there will be no blockage or bridging problems in the discharge;

* The anaerobic fermentation degradation time of pretreated straw is shortened from 60 days to three days;
