Projects on gasification
Natural gas is the most environmentally friendly type of fuel relative to other types of petroleum products. This is especially in light of the environmental sensitivity of the regions and climate change on the planet, since natural gas does not form smoke during combustion and does not leave ash after it, thus causing significantly less impact on the earth’s atmosphere. Gasification of the consumer sector and transport sector of the regions is one of the top priorities in combating climate change and reduction of the negative impact on the environment.
Gasification of the regions in the RoK
Nowadays 10 regions of the Republic of Kazakhstan are equipped with the gas supply systems. The main gas consumers in the country are industrial enterprises, which account for more 70 % of total consumption. At the same time, “General Scheme of Gasification of the Republic of Kazakhstan”, approved in 2014, sets a goal on provision of additional gas to more 600 population centers in Kazakhstan, which will lead to increase in consumption of natural gas to 18 billion cubic meters per year by 2030.
Provision of gas supply to the population is a priority task of KMG. However, connection of small population centers to gas supply system leads to significant capital expenditures.
Nowadays JSC “KazTransGas Aimak” successfully implements a large investment projects in the regions of Kazakhstan under the formula “tariffs in exchange for investments”. The company has already replaced thousands of kilometers of worn-out gas pipelines with new, high-quality and reliable ones.
Within the framework of investment programs for 2015–2021, it is planned to build gas pipelines with total length of about 5,000 km, including over 3,955 thousand km of gas pipelines, laid in 2015–2017:
- 5 population centers of Kyzylordinskaya oblast (Aralsk city, Ayteke bi village, Shieli village, Zhanakorgan village and Baikonurity);
- 10 population centers in Aktybinskaya oblast (Bogoslovka, Komsomol, Enbek, Taldysai, Kosestek, Akkuduk, Irgiz, Altyndy, Will, Zhaysan);
- 8 population centers in Kostanayskaya oblast (Kachar, Oktyabrsky, Nauchnoe-Toguzak, Antonovka, Alchanovka, Voroshilovka, Karabalyk, Boskol);
- 5 population centers in Mangistauskaya oblast (Zharma, Baskuduk, Batyr, Borankul, Beineu), continuation of gasification – in Beineu village and Batyr district of the Munayli district.
“KazTransGas Aimak” JSC will continue work on gasification of S. Shapagatov village, v. Mangistau, Beineu, Fort-Shevchenko of Mangistauskaya oblast, as well as Almaty and Almatinskaya oblast in the framework of approved investment programs in 2018–2021. At the same time more 740 km of new gas pipelines will be laid. Total amount of investment programs of “KazTransGas Aimak” JSC on gasification of regions and modernization of gas distribution systems in Kazakhstan for 2015–2021 is more 122 billion KZT.
Gasification of transport sector
It is known that main air pollutant is transport sector, accounting up to 60 % of all emissions. During analysis of the results of studies on toxicity of cars, it has been proved that in case of usage of natural gas instead of oil fuel, the release of toxic substances into the environment decreases approximately in 8 times by carbon monoxide, 2 times by nitrogen oxides, 3 times by hydrocarbons, in 9 times by smoke, and soot, which is typical for diesel engines, is not formed, corresponds to the EURO standard –5, 6. In terms of safety, methane is almost 2 times lighter than air; therefore, it immediately evaporates when depressurized, and does not settle as distinguished from other fuels. Moreover, resistance to low temperatures and concentration indicators of gases ignition is significantly higher than of gasoline, diesel fuel and liquefied hydrocarbon gas. Due to the fact that the gas is stored in cylinders under high pressure, the possibility of getting an air into them, which is necessary for ignition or explosion, is excluded, and also the possibility of manipulation with the octane number and theft of fuel are excluded.
“KazTransGaz Onimderi” LLP performs systematic work on re-equipment of its own transport for usage of gas engine fuel. Within the period from 2015 to 2017, 409 transport units were reequipped to gasoline engines, including 72 units during 2017, which promoted reduction of fuel costs on about 150 million KZT and reduction of pollutants emissions into the atmosphere.
Also, one of the activities in this area is construction of NGV refill station – NGVRS (gas refilling stations). Total number of NGVRS in the Republic of Kazakhstan is 15 units, 7 units belong to KTG group, including 1 NGVRS, commissioned in 2017. Works on expansion of filling infrastructure in the Republic of Kazakhstan is continuing, negotiations are performed with the local executive bodies. A memorandum of cooperation was concluded with Gazprom PJSC, CNPC and KMG JSC on development of filling infrastructure on CNG and LNG at ITC Western Europe – Western China. Work on preparation to international motor rally at CNG and LNG on this route is carried out.
Main consumers of methane are cars, working daily, with large runs and high fuel consumption. First of all, these are buses and municipal equipment. So, for example, about 700 buses are operated in Almaty on natural gas, which has a significant effect in reduction of pollution emissions.
According to economic, ecological, resource and technical criteria, methane will remain the best motor fuel for a long time. Usage of marketable gas will provide a socio-economic effect, which can be obtained in the result of transport transfer to natural gas, taking into account savings in maintenance of transport of municipal and private parks, ensuring import substitution of fuel, improving the environment and health of the population, fulfilling the obligations of the Republic of Kazakhstan in the area of struggle against global warming and other socio-economic indicators of the development of regions and the country as a whole, which can be taken into account during adoption of measures of state support and promotion of transition of Kazakhstani transport to use of natural gas as motor fuel.
Strategic medium-term plans of KazTransGas within gasification projects of the country include:
- Project implementation “Construction of 100 NGV refill stations”
- Selective commercialization of LNG production technology at GDS of the unified gas supply system of the Republic of Kazakhstan
- Development of LNG/CNG production-sale infrastructure on the international transport route “Western Europe – Western China”
- Implementation of the project “air monitoring of ground objects” (small aviation).
