Problem Description & Market Need
For facility industrial using it is necessary:
To adjust it to the sizes for practical usage;
To increase facility productivity;
To adjust this technology for the individual customer;
To adjust the technical documentation for the specific facility;
To find specific customer of this facility.
The potential market there are:
Agriculture
Factories of the food industry.
Plants of biological purification foul water.
Solid domestic waste dumps.
In one word anywhere where is organically waste.
Brief technology and facility description
Biogas (methane (СН4) and carbon dioxide (CO2) gaseous mixture) is fuel gaseous mixture with СН4 50%. Using of the biogas is important task for solving problems:
ecological – limitation of biogas atmospheric emission,
economical – additional energy source.
Facility and technologies of the biogas utilization was developed for solving of these tasks.
There are 6 separation modules, which work in turns, thus ensuring the continuity of the technological process.
Depending on composition of the input biogas and requirements for the end product, facility can consist from all modules or only from one module (separation one).
Facility allows to separate biogas into the components: СН4 and CO2.
Advantages
The main innovative aspects are using of the Pressure Swing Method (PSM). The small cycle duration and process room temperature allow making mobile separation facilities. These facilities combined with motor-generator, working at the produced methane, ensure autonomous facility operation.
Experimental results
Zeolites produced in Ukraine was chosen experimentally:
CaA for CO2 adsorption from biogas flow
NaA for biogas dehydration
Technology worked on developed laboratory model facility and have such characteristics:
liquefied almost pure methane in standard vessels with volume 5 liters under the pressure 20 MPa and with purity 96%;
liquid carbon dioxide at the similar vessels under the pressure 56 MPa;
solid carbon dioxide (dry ice).
productivity in biogas terms – 50 nm3/hour;
admixtures of the other components in the separated methane and carbon dioxide - ~4%
Targeted Market Segment
May be interested in such facility:
heads of the municipal waste treatment plants;
farmers having methane-tanks for biogas production;
owners of the domestic wastes dumps.
Cost of facility $17000.
