Chemical pigging apparatus including an inflatable device and method of using same

摘要

The remote controlled chemical pigging apparatus includes a housing and an inflatable device. The inflatable device contains chemicals to dissolve hardened or fossilized materials or contaminants contained within the interior portion of a pipeline, such as an oil or gas pipeline. At a specific location in the pipeline, such as at a pig apparatus receiver portion of the pipeline, the inflatable device is inflated and exploded to disperse the pipeline chemicals contained therein onto the hardened materials or contaminants that have fossilized within the pipeline. The hardened, fossilized materials or contaminants are then dissolved to liquefy the contaminants and, subsequently, to discharge the liquefied contaminants through a drain located in the pipeline. A method of cleaning a pipeline with a remote controlled chemical pigging apparatus having an inflatable device is also provided.

主权项

1. A chemical pigging apparatus to clean a pipeline, comprising: a housing; an inflatable device disposed on the housing, the inflatable device containing at least one pipeline cleaning chemical and one or more explosive agents; a control unit coupled to the inflatable device, the control unit to control inflating of the inflatable device to enable exploding of the inflatable device to disperse the at least one pipeline cleaning chemical into the pipeline; and a power source coupled to the control unit to provide power to explode the inflatable device, wherein the power source provides an electrical charge, to explode the one or more explosive agents to inflate and explode the inflatable device.
