In the United States, oil companies process and use natural gas or re-inject gas back into the ground, and only about 1 percent of gas is flared. In Nigeria, as much as 60 percent of associated gas is wasted in flares.
How much gas is flared?
The most recent data indicate that around 150 billion cubic metres (bcm) of natural gas was flared globally in 2019, as much gas as Japan and Korea together imported in the same year.
Why gas is flared in Nigeria?
The problem is the following: The domestic gas market in Nigeria is underdeveloped, due largely to dysfunctional pricing and other institutional issues in both electricity and natural gas markets. Oil sales supply a majority of government revenue, and a high share of Nigeria’s oil fields have associated gas.
Is gas flaring still happening in Nigeria?
Nigeria first targeted gas flaring in the late 1970s and, through various schemes and regulations, has more than halved it since 2001. Chevron, Shell and Eni, which operate in Nigeria, say they have cut flaring by some 90% and are working to cut it further.
How much gas is flared in Africa?
And yet, Africa flares around 40 billion cubic metres of gas, annually, of which 35 billion cubic metres are flared in sub-Saharan Africa.
Why is gas flared off?
It is common to flare natural gas that contains hydrogen sulfide (i.e., sour gas), in order to convert the highly toxic hydrogen sulfide gas into less toxic compounds. Flares emit a host of air pollutants, depending on the chemical composition of the gas being burned and the efficiency and temperature of the flare.
Is gas flaring dangerous?
Flaring emits powerful climate forcers and dangerous air pollutants like black carbon, methane, and volatile organic compounds. … Black carbon and methane are both powerful climate forcers and black carbon and VOCs are dangerous air pollutants.
Why is natural gas burnt in Nigeria?
Gas flares are created when oil companies burn off extra gas that escapes as a result of oil drilling. Gas flares burn several stories high throughout the Niger Delta, often within a few hundred yards of communities. Some flares, like the one pictured here, have been burning constantly day and night for over 30 years.
What are the effect of continuous gas flaring in Nigeria?
In Nigeria’s Niger Delta, gas flares are killing crops, polluting water and damaging human health.
What are the effect of gas flaring?
Gas flaring is commonplace during production or industrial activities on oil rigs, refineries, chemical and coal plants. In the process of flaring, excess amounts of carbon dioxide and methane are released into the atmosphere, resulting in depletion of the ozone layer, acid rain and global warming.
What are the unspoken dangers of gas flaring in Nigeria?
The combustion process raises the soil temperature, with a decline in crop yield and acid rains as its two major ripple effects. The smokes which emanate from the flares also lead to black rainfall and water bodies which affect aquatic and Wildlife. The economic costs of gas flaring are mind-boggling.
What gases can be flared?
Wastes or losses to the flare include process gases, fuel gas, steam, nitrogen and natural gas. Flaring systems can be installed on many places such as onshore and offshore platforms production fields, on transport ships and in port facilities, at storage tank farms and along distribution pipelines.
What are the unspoken dangers of gas flaring?
Pollution: Gas flaring leads to the emission of pollutants which are harmful to both humans and the environment. Byproducts such as carbon monoxide pollute the air and are associated with cancer, deformities in children, lung damage, skin problems etc.
How much gas is flared each year?
As a result, thousands of gas flares at oil production sites around the globe burn approximately 140 billion cubic meters of natural gas annually, causing more than 300 million tons of CO2 to be emitted to the atmosphere.
Is flaring better than venting?
Through the practice of flaring, methane is oxidized (through combustion) to carbon dioxide (CO2) and water. From an environmental standpoint, flaring is better than venting since CO2 is 25 times less impactful as a greenhouse gas than methane over a 100-year timespan.
Does flaring produce CO2?
The flaring of natural gas results in the release of carbon dioxide into the atmosphere in the same way that burning natural gas as a fuel would. Flaring releases significant greenhouse gas emissions into the atmosphere and doesn’t produce any work (useful energy) as a result. …
