Methane Gas BPLS neutralizing Install chimney

Sidoarjo - To reduce air pollution in the neighborhood residents, Sidoarjo Mud Management Agency (BPLS) install a chimney pipe six feet tall with a diameter of six inches, the pipe installation is intended to neutralize the methane gas that has reached the level of concentration up to 100 percent in the chute.

PR BPLS, Ahmad Zulkarnain, said, Previously, BPLS has just put up some pipes in the sewer, and since then the gas concentration decreases. If the original gas content of more than 100 percent, has now dropped to 70 percent.
Methane gas that is highly flammable. Methane content of 5-15 per cent in the air was enough to cause an explosion if there is fire. However, non-toxic if inhaled, because the gas is not found hydrogen sulfide toxicity (H2S).
However, methane can cause people to suffocate because it reduces the concentration of the gas is inhaled oxygen humans.

He added that this step will remain effective if the level is Low Explosive Limit (LEL) down significantly. Now LEL was 40 percent, will be graded down significantly if the LEL levels had dropped to 30 percent.

Previously, measurements of the gas monitors Fergaco, LEL or flammable gases methane type in the sewers around the blast have been over 100 percent within a radius of 25 meters. This means, the sewer had been dangerous and highly flammable if ignited fire
