City without chimneys
Communal systems for removal and reprocessing of wastes of two types - liquid (municipal sewage lines) and solid (collection and removal of wastes) - are operated in populated localities. Gas emissions are produced by each economic entity individually. For the time being there is no possibility for full system control and neutralization of dust and gas wastes because there is no system in the physical form which would enable comprehensive receipt of exit gases from all the city sources for further processing thereof.
B. The Problem Solving Strategy:
New holistic approach to “cleaning/treatment” of all city dust and gas emissions (wastes) is proposed which consists in creation of a City Communal Aspiration System (City without chimneys) containing a city communal aspiration network (gas outlets) for receipt/transportation of exhaust gases and plant for utilization of such wastes connected to such network.
C. Advantages and Technical Results:
1. Ecological: prevention of the air basin, water reservoirs and soil against pollution by means of radical reduction or liquidation of emission of gas venting in the air.
2. The system as an object integrating individual discrete elements is oriented towards resource saving and continuous objective control (counters) of gas emissions from all economic entities.
3. The city planning project is facilitated. Chimneys (an architectural "irritator") will be removed; possibilities for zoning, design and esthetic solutions will be expanded. The suggested concept complies with the ideology of the “ecological city” and “city of short ways”.
4. The system enables to utilize physical, chemical and kinetic potential of flue gases.
5. By inclusion of a counteragent into the common aspiration structure the society will avoid the risk (temptation) of unauthorized emissions.
6. Risks of formation of new “unexpected” harmful substances in the air will be reduced.
7. The possibility appears to resolve problems associated with ecological aggression (Transboundary Air Pollution).
8. The possibilities for transfer of production facilities from one type of fuel to another will be expanded.
D. Description: structural sequence:
1. Control of composition and amount of received gas wastes.
2. Gas treatment: removal of dust, mechanical particles; utilization of heat.
3. Vacuum fans (exhausters).
4. Utilization: here gas separation, filtration, neutralization, synthesis, pyrolysis and other operations may be realized with application of both well-known and future technologies.
Most of the above listed technical solutions and technologies have already been applied locally at emissions objects on the large-scale basis. This fact will materially facilitate integration of such components into the proposed system.
At the exit (output) from the utilization station, for example, three flows may be organized:
- The first flow (CCS), utilization of carbon dioxide - these may be geological technologies with underground pumping of СО2 to oil and gas deposits, unused coal deposits etc. The technology “CCS”– Carbon capture and storage has been already actively commercially used.
- The second block (R) - return (recycling) to the “production/consumption” circulation of exhaust gases (mixtures thereof).
-The third flow (P&D) - batching of gases for supply
