Abstract
Provided is a chemical injection system for connection to a chemical tank and a process line. The system includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.
Claims20
A chemical injection system for connection to a chemical tank and a process line, the chemical injection system comprising:
- a pump box configured to attach to the chemical tank, the pump box including a body defining an interior;
- a pump assembly disposed within the interior of the body of the pump box;
- and
- an injection assembly configured to be fluidly coupled to the pump box, the injection assembly including:
- an injection lance having a flange with first and second sides, a stem extending from the first side of the flange and configured to be received in the process line, a passage extending through the flange and stem, and one or more outlet ports in the stem extending perpendicular to and into the passage, the passage having an inlet at the second side of the flange for receiving a chemical;
- a first seal abutting the first side of the flange of the injection lance and configured to abut a flange of the process line;
- and
- a second seal abutting the second side of the flange of the injection lance.
A lance assembly comprising:
- an injection lance having a flange with first and second sides, a stem extending from the first side of the flange, a passage extending through the flange and stem, and one or more outlet ports in the stem extending perpendicular to and into the passage, the passage having an inlet at the second side of the flange and a closed inner end;
- a first seal abutting the first side of the flange of the injection lance and configured to abut a flange of a process line;
- a second seal abutting the second side of the flange of the injection lance;
- a connection flange having a first side abutting the second seal and a second side;
- and
- a hose barb connected to the connection flange at the second side.

- a first seal abutting the first side of the flange of the injection lance and configured to abut a flange of the process line;
- a second seal abutting the second side of the flange of the injection lance;
- a connection flange having a first side abutting the second seal and a second side;
- a hose barb connected to the connection flange at the second side;
- and
- one or more double containment conduits connected between the pump box and the injection lance, the one or more double containment conduits having an inner conduit fluidly connected to the injection lance for delivering the chemical from the pump assembly to the injection lance, and an outer conduit surrounding the inner conduit and being connected to the hose barb.
