Abstract
The disclosure describes a hatch clamp assembly that is a pipe clamp or cap sensor unit attached to a thief hatch and a chemical storage tank to detect, analyze and correct emission from the storage tank. The hatch clamp assembly creates an enclosure for capturing emissions from the storage tank, and sensors to monitor gas emissions attached to the hatch clamp assembly provide early detection of emission of gases.
Claims20
A pipe clamp sensor for adding to a separate thief hatch for emission monitoring, said pipe clamp sensor comprising:
- a) a pipe clamp configured to fit over a vertical annular flange on a base of a separate thief hatch and inside a cover of said separate thief hatch;
- b) an optional gasket on one or more edges of said pipe clamp to trap gas therein when said thief hatch cover is closed and latched;
- and
- c) a sensor package operably mounted to said pipe clamp and comprising i) a gas sensor configured to detect gas, and ii) a communicator configured to communicate said detected gas to an operator.
A pipe cap sensor for adding to a thief hatch for emission monitoring, said pipe cap sensor comprising:
- a) a pipe cap configured to fit over a separate thief hatch on a separate tank;
- b) a gasket on a bottom open edge of said pipe cap to trap gas between said tank and said pipe cap when said pipe cap is affixed over said separate thief hatch;
- and
- c) a sensor package operably mounted inside said pipe cap and comprising a gas sensor configured to detect gas and a communicator configured to communicate detection of said gas to an operator.
