Computerized Chemical Injection System For Hydrogen Sulfide Control In A Waste Water Stream
US Patent:
5356458, Oct 18, 1994
Filed:
Jun 8, 1993
Appl. No.:
8/074271
Inventors:
Younes Javadi - Sugerland TX
Randy L. Jones - Sugerland TX
Douglas F. Werner - Kingwood TX
Randy L. Jones - Sugerland TX
Douglas F. Werner - Kingwood TX
Assignee:
Clearwater Industries Corporation - Metairie LA
International Classification:
B01D 5314
US Classification:
95 13
Abstract:
A system for continuously monitoring the hydrogen sulfide concentration present in the atmosphere above a waste water stream, such as a sewerage stream, and for controlling the amount and time of injecting a specified chemical into the waste water stream in order to control the quantity of hydrogen sulfide which would evaporate into the atmosphere. This system comprises the steps of obtaining a sample of atmosphere above the stream; routing the sample of air through a sensor for determining the concentration of hydrogen sulfide gas within the quantity of air determining the amount of an amine-based dopant to add to the waste water; sending a signal from the controller to a chemical injection pump for injecting the determined quantity of chemical compound into the waste water stream to absorb some of the hydrogen sulfide gas; continually monitoring the stream for determining the concentration of hydrogen sulfide gas in the stream following the introduction of chemical compound thereunto; and adding additional compound on a continuing basis, as needed, depending on the concentration of hydrogen sulfide within the stream.
