Introduction Many of the waste gases from the refining of petroleum require incineration to prevent the emission of gaseous air pollutants. This treatment is designed: 1. To protect against fire and explosion hazards due to the release of combustible materials. 2. To avoid objectionable odors. 3. To meet the national ambient air quality standards for carbon monoxide and hydrocarbons. The three main types of refinery waste gases to be incinerated are: 1. Emergency releases of hydrocarbons from the process operations. 2. Combustible gases free from particulates and not yielding objectionable combustion products. 3. Combustible gases containing particulates or objectionable combustion products or both. Emergency releases of hydrocarbons from process operations are burned in flares. The design and operation of such flares and flare systems are the topic of Chapter 15 of this volume and will not be considered here. The processes and equipment used to incinerate the other waste gases are the same whether the emissions are clean enough to be released to the atmosphere or need further treatment. These operations will be discussed in Paragraph 14.2 Incinerator emissions containing excessive amounts of particulates or offensive combustion products must be treated before release. The equipment and processes that can be employed depend on the type and amount of contaminant and not on the kind of incinerator or the nature of the feed. Thus Paragraph 14.3 will cover the purification pf the gaseous emissions from all types of refinery incinerators whether feeding gases@ liquids@ or solids.
