A new way to develop mineral depositsGTLittle (mini-plants for producing synthetic oil or methanol from associated gas)
Kirill LIATS
General Director Metaprocess
Utilization of associated gas is an ecological and commercial
necessity
• Up to 25 billion m3 of associated gas is flared annually.
• This amount increases annually by 1-3 billion m3
• CO2 and other harmful substances are emitted when gas is flared
• The environment is heated globally and locally. The permafrost areas are especially endangered
• Losses: $500 million to $5 billion per year
There is a solution!
GTL – gas-to-liquid
Why GAS-TO-LIQUID?
• Absence of spare capacity in pipelines
• Monopolistic disbursing prices when shipping through main pipelines
• Remoteness from end consumers of natural gas
• High cost of building new gas pipelines
• Substantially lower costs when shipping a liquid product
Synthetic oil as a commercial productLogistics
• Synthetic oil – a string of hydrocarbons С5-С17 in liquid state at normal temperature
• Sulfur, asphaltens, aromatics are absent
• Output can be shifted toward paraffins or alpha-olefins
• Consumers: oil refineries, petrochemical plants
• Synthetic oil can be processed at minimum cost into motor fuels (gasoline, diesel fuel). The cetane number of the diesel fuel is 70.
Synthetic oil as a commercial productLogistics
• Used for own needs in gas production
• Used as a product for subsequent processing into formaldehydes, carbamide-formaldehyde tars, olefins.
• Other consumers: chemical plants, fertilizer plants, pulp and paper combines, woodworking and furniture factories
Advantages of designing mini-plants at the stage of developing oilfields
• Minimization of expenditures
• Reduction of ecological payments
• Obtaining a commercial product from waste material
• Capitalization of gas, facilitation of transporting it
• Possibility of optimizing the infrastructure of the mini-plant to fit the entire development program

Non-sponsor financing of GTLittle construction.The Strategic Reserves project
• Solving the problem of associated gas utilization by selling it at the site where it is fed to the processing company’s flare
• Solving the problem of monetizing non-transportable gas by selling it at the well of the processing company
• Providing the processing company with a site for building a GTL plant or unit
• The company "Strategic Reserves" is a partner and customer of Metaprocess Corp. which attracts investment for building plants and units for producing synthetic oil and methanol from natural and associated gas
GTL UnitPilot Fisher-Tropsch reactor
• Pilot unit of gas-to-liquid processing has been assembling
• It will be launched until 15-th of March in Novocherkassk
Permanent battle with flaring gasGas purification unit in Chechnya
• Dry gas sulfur purification unit
• Domestic consumption of clean oilwell gas
• Reduction of flaring 250 mln cubic metres of oilwell gas annually
