US Patent:

51267292, Jun 30, 1992

Filed:

Jul 21, 1989

Appl. No.:

7/385989

Inventors:

John M. McKinney - Indian Head Park IL
Ali D. Ata - Downers Grove IL
Robert B. Wierzba - Bridgeview IL
William F. Flowers - Naperville IL

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

H04B 300

US Classification:

34082506

Abstract:

An automated chemical storage and chemical feed system for a use station to chemically treat and monitor a process at a use station where the process is being run, including one or more base chemical supply tanks at the use station storing chemicals and intermittently or continuously feeding the chemicals to the process. A level sensor is provided in each base tank to determine the chemical level and to deliver a signal to a control and processing unit. Sensors may be provided on the process for providing chemical condition information to the control and processing unit. A telemetry system receives the information from the control and processing unit and transmits it to a supply station where the information is recorded and read out to monitor the chemical supply in the base tank and to monitor the chemical condition of the process so that the chemical feed may be adjusted as needed and so that further chemical may be delivered to the use station to be introduced into the base tank and maintain an adequate supply to prevent interruption of the process. Refill tanks are shipped from the supply station to the use station, transported to the base tank, and emptied into the base tank. Thereafter, the refill tanks are returned to the supply station to be refilled.

An automated chemical storage and feed system for a use station to chemically treat and monitor a process at a use station where the process is being run, including one or more base tanks at the use station storing chemicals and having means intermittently or continuously feeding the chemicals to the process. A level sensor is provided in each base tank to determine the chemical level and to deliver a signal to a control and processing unit. Sensors may be provided on the process for generating chemical condition information to the control and processing unit. A telemetry system receives the information from the control and processing unit and transmits it to a supply station where the information is recorded and read out by a person to monitor the chemical supply in the base tank and to monitor the chemical condition of the process so that the chemical feed may be adjusted as needed from the supply station and so that futher chemical may be delivered to the use station to be introduced into the base tank for maintaining an adequate supply to prevent interruption of the process. Refill tanks are shipped from the supply station to the use station, transported to the base tank, and emptied into the base tank. Thereafter, the refill tanks are returned to the supply station to be refilled.
