Abstract
The present invention generally comprises a storage vessel for the polymeric slurry chemical, a vapor recirculation system, a chemical recirculation system, a device for chemical temperature control, a device for measuring storage vessel level, a device for metering and pumping chemical, and a device for controlling apparatus. The vapor recirculation system, chemical recirculation system, mechanism for chemical temperature control, mechanism for measuring storage vessel level, mechanism for metering and pumping and mechanism for controlling apparatus are housed in the pumping equipment container and are connected to the storage vessel by control conduits, and piping for vapors and liquid chemicals to make the complete apparatus. The apparatus is used to maintain slurry materials in a usable state and to inject the slurry materials as required for specific applications, such as injecting drag reducing agent into operating pipelines.
