It has been noted (Section 5.1.2.3) that production of tetraalkyllead compounds gives rise to effluent streams contaminated with gaseous organic lead compounds. These cannot be controlled by the application of particulate control technology, and considerable effort has been expended in recent years to achieve satisfactory control. Present practice in England involves the use of an activated carbon absorption plant, followed by recovery of absorbed lead by steam stripping [7].

Air Pollution. Particulates and sulfur dioxide emissions from commercial oil shale operations would require proper control technology. Compliance monitoring carried out at the Unocal Parachute Creek Project for respirable particulates, oxides of nitrogen, and sulfur dioxide from 1986 to 1990 indicate a +99% reduction in sulfur emissions at the retort and shale oil upgrading faciUties. No violations for unauthorized air emissions were issued by the U.S. Environmental Protection Agency during this time (62). 

The principal technological changes in the engineering control of air pollution were the perfection of the motor-driven fan, which allowed large-scale gas-treating systems to be built the invention of the electrostatic precipitator, which made particulate control in many processes feasible and the development of a chemical engineering capability for the design of process equipment, which made the control of gas and vapor effluents feasible.

Air pollution from exhaust emissions NO t and particulate matter from exhaust emissions causing air pollution are -1% at present. By adoption of better combustion control technology, better quality fuels (or even fuel cell-based motor vehicles), and more efficient catalytic converters, researchers aim to mitigate this problem. 

Finally, it predicted a significant expansion of applications for this technology because interim particulate control is now recognized as both inexpensive, rapid and highly feasible.
