The City Without Chimneys – The City Communal Aspiration System

It is for the first time when a principally 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 containing a city communal aspiration network (gas outlets) for receipt/transportation of exhaust (flue) gases and aplant for utilization of such wastes connected to such network. In other words, it is proposed to organize a “City without chimneys”

Detailed Solution description

The City Without Chimneys – The City Communal Aspiration System

1. Problem
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 – whether they are a large industrial enterprise, a boiler-house or a household (dwelling house). 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.

2. The Problem Solving Strategy
It is for the first time when a principally 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 containing a city communal aspiration network (gas outlets) for receipt/transportation of exhaust (flue) gases and aplant for utilization of such wastes connected to such network. In other words, it is proposed to organize a “City without chimneys” (Figure).

3. Advantages and Technical Results of the Proposed Solution:

  • First – Ecological advantage: 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. 
  • Second – 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. 
  • Third– 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”. 
  • Fourth – The system enables to utilize physical, chemical and kinetic potential of flue gases.  
  • Fifth – By inclusion of a counteragent into the common aspiration structure the society will avoid the risk (temptation) of unauthorized emissions which exists in case of individual operation of this entity out of the system.
  • Sixth – Risks of formation of new “unexpected” harmful substances in the air will be reduced. The probability of formation of acid fogs and acid precipitations will be reduced.
  • Seventh – The possibility appears to resolve problems associated with ecological aggression (see the Convention on Long-range Transboundary Air Pollution).
  • Eighth – The possibilities for transfer of production facilities from one type of fuel to another will be expanded.

4. Description of the City Communal Aspiration System
An option of gas processing at the utilization station may be presented in the following structural sequence:  

  • 1 – Control of composition and amount of received gas wastes. 
  • 2 -Gas treatment: removal of dust, mechanical particles.In this block withdrawal and utilization of heat may be effected through a heat exchanger. 
  • 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 СОto oil and gas deposits, unused coal deposits etc. The technology “CCS”– Carbon capture and storage – has been already activelycommercially 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 and use.

The aspiration network (routes,lines and reservoirs)may, on the basis of specific conditions, include channels of both artificial origin (mines, tunnels, collectors…) and channel formations in form of natural geological formations.The city communal aspiration network may be integrated with other structures ensuring forced transportation of wastes in form of liquids, effluent waters, pulp, slurry, solid substances etc. In other words, depending on economic and technological conditions and links, it is logical to move towards the total utilization of all types of wastes generated by production and household activities of a human.

P.S.  – Importance and practical value of the idea: Elimination of certain ecological difficulties associated with climate change and urbanism. – Practicability: Technological and scientific-technical level of society development is sufficient for implementation of the idea and shall be enforced by the organizational component.
