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
