Stopping air pollution

Ramboll was given the task of remodelling and enlarging an existing old flare system at the Dukhan oil field on the west coast of Qatar.  In addition, we were to find a method for reclaiming some of the gas that would otherwise be burnt in the tower. At last, we were to implement improved combustion technology to obtain what is known as a “smokeless flare”- which means a flame without smoke.

Improved combustion

For many years, the Dukhan oil field has suffered from highly polluting smoke from the flares. Especially during wind still periods, there has been a heavy cloud of smog over the area. With the new technology, compressed air is pumped into the flame and burning gas, using a special nozzle system, whereby an improved and smokeless combustion is achieved.

New combustion technology

Ramboll introduced new technology to prevent the polluting and unhealthy smog from the flare tower on the oil and gas system. The flare system on oil and gas installations is used to collect and burn gas from the installation. It is used for example when it is required to relieve the installation from too high gas pressure or when it is required to empty and close down the installation. The gas is led to the flare tower, where an eternal small flame is burning – which then ignites evacuated gas and burns it off.

Similar projects with good results

A couple of years ago, Ramboll performed a similar project for RasGas, a big Liquefied Natural Gas company in Qatar. Here, there were also problems with a highly polluting flare, and we designed an improved system with a very good effect on the combustion.
