Coagulation is one of the methods of industrial scale production of drinking water from surface sources (rivers, water reservoirs), and preparatory treatment of water prior to industrial application (steam generators, steam turbines), as well as of purification of industrial and municipal waste water. Aluminum and ferrum sulphate, chloride and chlorohydrate are traditionally used as coagulation reagents. A new coagulant has been recently introduced to the market, which provides for high quality water purification. This is titanium coagulant. The industrial scale production of the unique product is carried out by CJSC SITTEC, an IFD Kapital Group company which was established for that purpose in 2008.
Exceptional quality of water purification
SITTEC is an innovative chemical for drinking water production and industrial and municipal waste water treatment. The exceptional effectiveness of the reagent has already been proved. The concept of valence confirms higher relative activity of titanium compared with aluminum and ferrum. Aluminum and ferrum based coagulants are inferior to titanium coagulant in their performance. Moreover, data received following numerous tests, showed that titanium containing materials evolve ions into water, which have bacteriostatic effect. Thus, titanium coagulant possesses disinfectant properties, which allow sufficiently reducing the amount of chlorine used for water disinfection in water treatment facilities, or, in some cases, even abandoning the use of chlorine completely. The economic efficiency of titanium coagulant is accounted for by significant reduction in water treatment and purification costs.
SITTEC is part of IFD Kapital Group, which is one of the largest diversified holdings in Russia. The Group invests in oil and gas sector, construction, chemical industry, mass media, and high technologies. Over two billion roubles are supposed to be invested in the titanium coagulant production complex. Engineering works, pilot-scale production and tests, preparation of construction project documentation, and state expert appraisal had been conducted before 2011, and in 2011 construction works began. Most of the production equipment has been custom-build and is a unique non-standardized equipment. Titanium coagulant production is planned to start in 2014 with the total production volume of 25,000 tonnes per year.
The project assumes special prominence in light of state import substitution strategy and the Pure Water Federal Target Programme aimed at providing high-quality drinking water to the entire Russian population before 2017.
Titanium resources development
Yarega oil and titanium deposit was chosen as raw-materials base for the production. This is one of the largest titanium resources in Russia (over 640 million tonnes of titanium ore) located in the Ukhta Region, an industrial Komi region with highly-developed infrastructure. The reserves had been explored with all the possible accuracy, but had not yet been developed at industrial scale. The titanium coagulant production became the first practical level project of commercial development of Yarega deposit’s titanium component.
This is a unique resource with huge reserves of heavy crude oil and titanium ore in one flat-lying formation of quartz sandstone. Oil and titanium ore is produced by Yareganeft Oil Mine Management, which is part of LUKOIL-Komi LLC, an active participant in the titanium coagulant production project. The enriched leucoxene quartz sandstone is then transported to SITTEC’s facilities for further processing and titanium concentrate production. The experimental-industrial titanium ore enrichment factory was reconstructed specially for this purpose. In 2012, SITTEC and CJSC Mekhanobr Engineering (Saint Petersburg) worked out new process regulations for the enrichment factory with the productive capacity of 35 thousand tonnes of ore per year. In 2013, balancing and commissioning works were carried out following the results of re-equipment. At the same time, the company constructed a pulp-line and external engineering networks linking the enrichment factory with the new titanium coagulant chemical production.
It is noteworthy that at all stages of the work SITTEC pays special attention to health, safety, and environmental protection. The company has obtained a Rostekhnadzor approved State environmental appraisal review confirming that the titanium coagulant production technology complies with environmental requirements. In January 2013, the company also obtained a certificate confirming that its environmental management system conforms to ISO 14001:2004 standard. The State Registration Certificate confirms that titanium coagulant fully meets sanitary-epidemiological and hygienic requirements set in the Customs Union.
Increased oil production efficiency
Along with the construction of production facilities SITTEC is carrying out extensive pilot-scale and industrial-scale tests of titanium coagulant in the facilities of future consumers, municipal water treatment organizations, and industrial enterprises. The tests have spanned a wide range of areas from Norilsk, Usinsk, Astrakhan, Tyumen, Ukhta, Syktyvkar, and Tobolsk to Perm and other cities in Russia, as well as abroad, in EU and East Asian countries, namely Jordan and Israel. The tests confirmed the exceptional performance of titanium coagulant for all the parameters of drinking water quality, as well as its efficiency both in industrial sphere and in public utilities.
SITTEC pays special attention to titanium coagulant industrial application. The company has carried out tests in LUKOIL producing, processing, and energy generating enterprises since 2011. In December 2012, LUKOIL-Perm LLC, LUKOIL-Engineering LLC, and SITTEC started joint programme of titanium coagulant pilot-scale application for treatment of produced water in the reservoir pressure maintenance system in Malo-Usinskoe deposit, Perm Krai. The programme is aimed at proving the advantages of titanium coagulant in treating produced salt water in the reservoir pressure maintenance system. It is also supposed to increase the effectiveness of oil production through injection of pure water into a reservoir with thin colmatage layer. The percentage of residual petroleum products and suspended elements within the first months of the tests was much lower than that required for injection in the reservoir. Following the results of the tests, over 120 thousand cubic metres of water were treated within a year with the estimated volume of additional oil recovery of 4%. SITTEC is planning to conduct industrial tests in other oil production facilities and expand titanium coagulant application in oil and gas industry.
