The most widespread and persistent urban pollution problem is ozone. The causes of this and the lesser problem of CO and PMjq pollution in our urban areas are largely due to the diversity and number of urban air pollution sources. One component of urban smog, hydrocarbons, comes from automobile emissions, petroleum refineries, chemical plants, dry cleaners, gasoline stations, house painting, and printing shops. Another key component, nitrogen oxides, comes from the combustion of fuel for transportation, utilities, and industries.

Propylene is traded commercially in three grades refinery, chemical, and polymer grades. The difference is almost entirely the ratio of propylene to propane in the stream. Refinery grade propylene usually runs about 50—70% propylene chemical grade 90-92% polymer grade is at least 99% propylene. The remaining percentage is almost all propane in each case. 

Primary organics are emitted to the atmosphere by industrial sources (oil refineries, chemical plants, producers and users of solvents and plasticizers), vehicles (as a result of incomplete fuel combustion, oxygenated degradation products of lubricating oil, polymers from tires), and agricultural activities (use of pesticides). An exhaustive literature survey is beyond the scope of this section, but can be found in Air Quaiity Criteria for Particulate Matter many useful references are also available. 

Open Structures—structures supporting equipment or operations not enclosed within building walls, such as those found in refineries, chemical processing, or power plants. Roofs or canopies without enclosing walls should not be considered an enclosure.

Addresses piping typically found in petroleum refineries chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants and related processing plants and terminals. 

Indirect cost normally ranges from 20 to 35% of material plus labor of the modular major equipment cost. In most cost analysis of complete processing units, the indirect cost is very significant. Indirect cost factors should therefore always be a part of the summary sheet s total cost analysis and never overlooked. For most refinery, chemical plant, and oil- and gas-treating facilities, a 25% indirect cost factor is a well-accepted number in the industry, worldwide. The 25% factor of the material plus labor is therefore advised and is used in this chapter. 

Petrochemical processes require smaller reactors than used in refineries. Chemical reactors are sized in the 50 to 250 cu.ft. range. Orders for replacement catalyst usually range from 10,000 to 50,000 lbs, but there are many different process applications. Catalyst quality is becoming more important than in recent years as many industries attempt to reduce the cost of nonconformance and improve the quality of manufactured goods.

The U.S. Environmental Protection Agency reported extensively on its R and D programmes for detoxifying hazardous waste, e.g., from deserted refineries, chemical plants, herbicide and pesticide factories and storage facilities, etc. An interesting contribution was made by Col. D. Naugle, the Deputy Director of Environmental Policy, U.S. Department of Defense, which inevitably has to handle immense quantities of hazardous waste. The...

Remaining production and usage is distributed over a host of industries, many of which are not commonly known. Others include nonferrous metal producers (copper, lead, zinc, etc.), the cement industry, petroleum and hydrocarbon refineries, chemical producers, pulp and paper, food production-related industries anything involving heat and/or hot products. Although only a minor consumer, NASA utilizes refractory tiles to protect astronauts from the harsh conditions that exist on operation of the space shuttle and a refractory brick pad to manage the heat load associated with launch. 

A study on the spatial and temporal distribution of PAHs from various sources (wood-preserving facilities, refineries, chemical manufacturers, etc.) was reported by Huntley et al. (1995). The concentrations of PAHs were shown to increase with sediment depth from analysis of core samples. Samples were analyzed using EPA Method 8310 (GC/MS).
