Air Pollutant Control Techniques for Phosphate Rock Processing Industry.

摘要

This document provides information needed by state and local pollution control agencies for development of regulations for control of particulate emissions from phosphate rock processing plants. Information on process and particulate emission control equipment is included for phosphate rock dryers, calciners,grinders,and ground rock handling equipment. Cost and economic information is given for both new and retrofitted facilities,and environmental impacts are presented for different levels of emission control. Results of emission measurements performed by EPA at phosphate rock dryers, calciners,and grinders are tabulated and presented with brief descriptions of the facilities tested. EPA particulate emission test methods are also briefly described. Information presented in the document is summed up in an objective discussion of regulatory options and enforcement aspects of potential regulations.
