Complex Technology Line – KTL

Tengizchevroil inherited an oil and gas separation plant when it took over operations at Tengiz in 1993. This first generation of the Tengiz plant is called the KTLs (Russian for Complex Technology Lines). TCO has invested in expanding and improving the KTLs over the life of the operation. Today, the KTLs consist of five oil and gas processing trains and are now significantly more efficient and environmentally friendly. Started up in 1991, KTL-1 consists of two trains and has the capacity of around 7,000 tons per day per train. KTL-2, which also has two trains with the same capacity was successfully completed and started up in 1996. Last KTL train 5 was put on production in 2001 along with first oil from Korolev field. The capacity of train 5 is around 11-12,000 tons, per day.

Second Generation Plant – SGP

TCO's production capacity has risen with the commissioning of the Second-Generation Expansion Project in 2008, which includes the Second Generation Plant (SGP) and Sour Gas Injection (SGI) facilities. This expansion allowed TCO not only to double oil production in Tengiz, but also to improve the environmental performance and increase production efficiency. TCO completed the expansion in the third quarter of 2008, which brought daily capacity to 75,000 metric tons (600,000 barrels) of crude oil and 22 million cubic meters (750 million standard cubic feet) of gas. SGP stabilizes and sweetens crude oil, as well as separates and processes natural gas into gas products and elemental sulfur. SGP is the largest single sour crude processing train in the world.

This project, financed by TCO, was created to support the development of small and medium-sized businesses in Zhylyoi district within framework of the TCO’s Development Program in Zhylyoi district.

The winners’ names of the first batch of the Tandau project, implemented by the Eurasia Foundation of Central Asia (EFCA) were announced in Kulsary city. This project, financed by TCO, was created to support the development of small and medium-sized businesses in Zhylyoi district within framework of the TCO’s Development Program in Zhylyoi district.

Gulnafis Aishuakova, Deputy Akim of Zhylyoi district noted the importance of such a project for the region. “The new year began with great news – thirteen entrepreneurs received grants for the implementation of their business projects. On behalf of the district administration, we express our gratitude to TCO for supporting small and medium-sized businesses. I hope that the project will last for more than one year and demonstrate outstanding results. And I would like to wish the winners best of luck in their endeavors and note that the future of the project will depend on their success”.

According to the results of the first group, thirteen residents of Kulsary received grants ranging from 2 million to 4.5 million tenge, to implement their business ideas. These include the opening of an enterology center, a flower shop, cleaning and dry-cleaning services, poultry breeding, production of national dairy products and other business areas.

One of the winners, Mafu Rzabayeva, received a loan of 2.5 million tenge for opening a laundry. This will allow her to provide jobs for the local residents.

“The Tandau project allowed me to learn more about marketing, finance and business management, as well as realize my dream of expanding my business. My goal is not just to expand the business, but above all to create new jobs, to support Kulsary residents, and women in need of comfortable work and pay. I would like to wish that there were as many such projects as possible in Zhylyoi district!”, — said Mafu Rzabayeva.

It should be noted that among the winners, six people received grants of up to 2.5 million tenge, and seven people received grants up to 4.5 million tenge. With these funds, entrepreneurs will be able to purchase the necessary equipment. This is one of the conditions of the project – the allocated funds should be spent only for the purchase of required equipment. Entrepreneurs are given 6 months to launch their businesses, after which they are required to begin a staged refund. In the future, the funds will be used to finance the next upcoming business ideas.

Since it’s launch last fall, the “Tandau” project has attracted attention of one hundred and eight participants, of whom thirty-five have successfully qualified for the semifinals. It should be noted that ten of the thirteen winners are women. Two more project phases will be implemented during the year. In general, it is planned to provide support to about thirty representatives of small and medium-sized businesses in Zhylyoi district per year. Recruitment for the second course of study has already begun and applications are accepted from representatives of Kulsary on “tandau_zhylyoi” social media page.
