n: a gas that forms an acid when mixed with water. In petroleum production and processing, the most common acid gases are hydrogen sulphide and carbon dioxide. Both cause corrosion, and hydrogen sulphide is very poisonous.

n: The mixture made by gas and water presents acidity. The gas is acid gas. The usual acid gases are hydrogen sulphide and carbon dioxide in oil and gas drilling. Both of them are acrid and hydrogen sulphide is very toxic.


any produced gas, primarily H2S and CO2 that form an acid when produced in water.

v: The natural gas which is consisted of a number of hydrogen sulphide and carbon dioxide kick

n: a chemical family of specific organic compounds, including monoethanolamine (MEA),diethanolamine (OEA),and triethanolamine (TEA). These chemicals, and proprietary mixtures containing them and other amines, are used extensively for the removal of hydrogen sulphide and carbon dioxide from other gases and are particularly adapted for obtaining the low acid gas residuals that are usually specified by pipelines.

n: any of several compounds employed in treating natural gas. Amines are generally used to remove hydrogen sulphide from water solutions and carbon dioxide from gas or liquid streams.

n: I. the process of breaking down organic wastes with microbes. Bacteria that are naturally present in the environment use microbial enzymes to break down die materials into a soluble form that passes through the cell walls of the bacteria. The bacteria metabolise d1e material and convert it into components d1at are more readily assimilated in d1e environment, such as water or carbon dioxide (i.e., a gardeners compost pile). 2. the creation of engineered and managed conditions to boost natural bioremediation processes. Nutrients are added to stimulate the bacteria naturally present in the waste. Oxygen ari1 pH levels are adjusted for maximum effectiveness, and, if conditions are right, the bacteria grow in large numbers and break down the hydrocarbons much more rapidly than with natural bioremediation. In cases in which the necessary bacteria are not already present in the waste, suppliers can provide diem along with die appropriate nutrients.

n: a colourless, odourless gaseous compound of carbon and oxygen, A product of combustion and a filler for fire extinguishers, this heavier-than-air gas can collect in low-lying areas, where it may displace oxygen and present the hazard of anoxia.

a colorless gas. Corrosive when occurring with water. An acid gas. The most common cause of corrosion in the oil industry.

n: Refers to the carbon dioxide bullet used as the pressure origin of filter press of drill fluid.

n: see hypercapnia.
