BIB DRA natural gas increased gas efficiency, increase output 10%

The main mode of transport natural gas pipeline natural gas DRA, to enhance the amount of pipeline gas transportation, natural gas development is the mainstream of the world today, but in the course of piped natural gas, the pressure loss due to friction caused by the wall, people must first test the problem, especially for high Reynolds number turbulence gas, the pressure loss caused by the rough wall the greatest impact, in order to reduce the pressure loss, increase the amount of gas is a major issue of concern at home and abroad competing scientists. At present, domestic and widely used in the pipe coating drag reduction technology to reduce the pipe wall roughness. But the pipe coating drag reduction method, construction equipment complexity, high cost, especially with the extension of gas transmission time and from time to time pigging. Continue to fall within the pipe coating. Drag reduction effect gradually reduced, even when serious negative effects. DRA natural gas in the late 1990s, the US and Europe and other countries were studied aspects related to natural gas DRA, but have stayed in the theoretical and laboratory trials. China Petroleum Pipeline Pipeline Research Institute of Chemical Technology Research Center, uses advanced molecular design technology, developed BIB DRA series of natural gas, we made a good drag reduction effect increased output. And first in the world to achieve the advanced level of industrial production and application. To become a leader in the related art. Under the circumstances do not affect the normal operation, the system by injecting atomized into the gas pipeline line, due to the natural gas DRA has a special molecular structure, so not only can reduce the uneven parts of the wall roughness, filling the grooves, etc., but in the pipe surface, forming a layer of elastic film, so inelastic collisions of gas molecules with the wall becomes elastic collision. This can reduce the friction, the gas molecules without loss of energy between the wall and the gas, so as to achieve energy-saving effect drag reduction, therefore, natural gas DRA not only be applied to the inner coating of the inner pipe can also be used in there are inner coating of the pipe, according to the fuel saving can be achieved by an elastic membrane enhance the role of drag reduction pipeline transportation. Effect 1, the pipe wall with strong adhesive force. 2, a long-chain molecule with flexible, able to absorb the turbulent energy of the gas. 3, capable of forming a continuous film of liquid stable. 4, the drag reduction rate of 10% -20% are stable over 60 days (depending on whether the pipeline has an inner coating to availability). 5, every year approximately one hundred kilometers per dosage 4-5 tonnes (according to the diameter of the tube from quantitative). The results in 2009 in Changqing Oilfield Gas Plant to carry out spot using natural gas DRA, without affecting the normal operation of the gas pipeline, the average friction coefficient lower than the previous pigging lost 19.5% increase 11.5%, transport 12.4% efficiency, the effect can be stable more than two months. 2010 blue silver line after injection agent, friction coefficient decreases were more than 10%, can increase pipeline capacity of more than 10.5%, the effect can be stable more than two months.
