Gas processing

Premium Engineering and its partners are ready to offer their services in the engineering and fabrication of modular units for the utilization of associated petroleum gas (currently flared), low-pressure gas, coal bed methane, and excess natural gas.

Using the latest technology and equipment we offer the following:

  • Processing gas and other raw materials in the field. We process natural gas, associated petroleum gas, low-pressure gas from small and marginal fields, and other raw materials which yield commercial products.
  • Solving ecological problems and making it possible to observe license agreement conditions: we eliminate the flaring of associated petroleum gas.
  • Independence from existing power supply sources, infrastructure and traffic schemes. We supply units complete with power and heat sources which can be used in remote areas.
  • Reduction in capital expenditures and operating costs.

Lately, it has been the trend to process both associated petroleum gas from developing oil fields and gas condensate as produced alongside gas from gas-condensate fields. This trend is due to several reasons: the growth of oil and gas production, more stringent ecological standards, the gradual depletion of "dry" Senomanian gas reserves, and the fact that, in recent times, the number of newly discovered gas condensate fields is increasing.

Conditioned natural gas and associated petroleum gas are used as domestic fuel and for generating cheap power.

Natural gas can also be used for the production of so called syngas (a mixture of СО and Н2), which is used in many organic synthesis processes.

Gas processing products are widely used in the petrochemical industry for a variety of purposes. The liquid product extracted from gas - unstable natural gasoline – is fractionated (separated into fractions) in the refinery or gas processing plant. From unstable natural gasoline liquefied gases are extracted as a mixture of propane and butane, or as individual hydrocarbons and natural gasoline. Some refineries produce elemental sulfur, ethane, and helium.

Liquefied gases are widely used as a raw material for the petrochemical industry, as motor fuel, domestic fuel, and for supplying gas to communities, to business enterprises, cattle farms, etc.

Today, the principal users of liquefied gases are petrochemical plants. Ethane, propane, n-butane, as well as natural gasoline and hexane are used as raw materials for the production of ethylene, which, in turn, is used to produce ethanol, glycerin, ethylene glycol, dichloroethane, ethyl-chloride, etc. The further processing of these substances produces varnishes, solvents, paints, detergents, synthetic rubber, polyethylene, and polypropylene.

Butane is used to produce synthetic butadiene rubber; i-butane and i-pentane are used to produce synthetic isoprene rubber, which has the same characteristics as natural rubber.

Natural gasoline is used in refineries as an additive to improve automotive gasolines.

Liquefied hydrocarbon gases are suitable for use as domestic fuel due to their ability to be gaseous at normal conditions and to become liquid at a relatively low gage pressure.

There is no need to transport liquefied hydrocarbon gases through a massive pipeline network; they can be distributed in gas bottles and transported in specially designed railway tank cars.
