What is the term for controlled burning of liquid or gas to dispose of or reduce the product?

The term for the controlled burning of liquid or gas to dispose of or reduce the product is flaring. This process is specifically designed for the safe combustion of excess gases or liquids, often in industrial settings. Flaring is commonly utilized in the oil and gas industry to burn off gases that cannot be processed or sold, ensuring that harmful emissions do not enter the atmosphere.

Flaring involves the release of the gas or liquid at high temperatures, allowing it to combust efficiently and safely, transforming it into less harmful substances such as carbon dioxide and water vapor. This method helps manage waste products while minimizing environmental impact.

In contrast, combustion is a broader term that refers to any chemical reaction involving the burning of substances in the presence of oxygen, including both controlled and uncontrolled fires. Incineration is a process that typically involves the complete burning of waste materials in a controlled environment, usually at high temperatures, to reduce them to ash, flue gas, and heat. Vaporization is the process of converting a substance from a liquid to a gas, which does not imply any burning or waste disposal function. Hence, flaring is the most accurate term for the controlled burning of liquid or gas specifically for reduction or disposal.
