Natural gas (СН4) leakage

1. “Reduction of Natural Gas Emissions at OJSC "Odesagas" Gate Stations and Gas Distribution Networks”, Ukraine.

The main purpose of the project is reduction of natural gas (methane) leakage in gas-distribution posts, and in cabinet gas-distribution posts. The main sources of leakage are junctions of the elements of GDP and cabinet gas-distribution posts CGDP. Repair of leaking junctions of GDP and CGDP elements within the scope of this project vary from replacement of gaskets and wedge plugs, use of new sealants or compacting hermetic materials (such as Gore-Tex), to capital repair and replacement of safety valves of pressure regulators, piston rods, installation of natural gas gauges.

2. “Reduction of Methane Emissions at Flanged, Threaded Joints and Shut-down Devices of OJSC "Odesagas" Equipment”, Ukraine.

The main purpose of the project is reduction of natural gas leakage at gas transport and gas distribution infrastructure of JSC Odesagas. The main sources of leakage are switch mechanisms (bolts, cocks, valves), flange and threaded joints of gas pipelines of JSC Odesagas in the amount of 11 174 pieces. The main reason for natural gas leakage is quick failure of sealant elements. Elimination of all detected leakages by repairs of leaking equipment under this project vary from replacement of gaskets and wedge valves, use of new compactors or sealing materials, to capital repairs and replacement of safety valves of pressure regulators and piston rods.

3. “Reduction of Methane Leakage at Flanged, Threaded Joints and shut-down Devices of the Equipment of OJSC "Kyivgas”, Ukraine.

The main purpose of the project is reduction of natural gas leakage at gas transport and gas distribution infrastructure of OJSC “Kyivgas”. The main sources of leakage are switch mechanisms (bolts, cocks,valves), flange and threaded joints of gas pipelines of OJSC “Kyivgas” in the amount of 60 613pieces. The main reason for natural gas leakage is quick failure of sealant elements. Elimination of all detected leakages: repairs of leaking equipment under this project vary from replacement of gaskets and wedge valves, use of new compactors or sealing materials, to capital repairs and replacement of equipment.

4. “Reduction of Methane Emissions on the Gas Equipment of Gas-distributing Points and on the Gas Armature of Gas-distributing Networks of CJSC “Theodosia”, Ukraine

The main purpose of the project is reduction of the natural gas emissions at gas-transport and gas-distributing infrastructure of CJSC “Theodosia”, which are the result of leakage from gas equipment and gas armature. The elimination of methane emissions from gas equipment and gas armature is performed through three types of repairs used:
1. Complete substitution of out-of-date and morally threadbare gas equipment and gas armature by new units.
2. Repair of gas equipment components and gas armature;
3. Replacement of pressure-sealing elements with the use of modern sealing materials, changing practice of service and repair, that has become common, on the basis of paronite gaskets, and also sealing stuffing of cotton fibres with fatty impregnation and asbestos-graphite filler.

5. “Reduction of Methane Emissions on the Gas Equipment of Gas-distributing Points and on the Gas Armature of Gas-distributing Networks of PJSC "Mariupolgaz", Ukraine.

The main purpose of the project is reduction of the natural gas emissions at gas-transport and gas-distributing infrastructure of PJSC «Mariupolgaz», which are the result of leakage from gas equipment and gas armature. Removal of the emissions is performed through repairs of gas equipment of GDP (CGDP) and gas armature at gas pipelines: replacement of sealing elements or pressure-sealing, major repairs and replacement of gas equipment and gas armature by new, modern equipment.
