Abstract
A chemical injection system for connection to a chemical tank and a process line 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 lance assembly comprising:
- an injection lance having a flange with first and second sides, a stem extending from the first side of the flange, and a passage extending through the flange and stem;
- a connection flange with first and second sides, the first side proximate the second side of the flange of the injection lance;
- a first seal arranged between the second side of the flange of the injection lance and the first side of the connection flange;
- and
- a hose barb connected to the connection flange at the second side.
An injection system comprising:
- a conduit assembly configured to contain flowing fluid;
- and
- a lance assembly coupled to a first end of the conduit assembly and comprising:
- an injection lance comprising an injection flange, a stem extending from a first side of the injection flange, and a first passage extending through the injection flange and stem,
- a first seal arranged on the first side of the injection flange for sealing to a process line,
- a connection flange arranged over a second side of the injection lance and comprising a second passage extending through the connection flange,
- a second seal arranged between the second side of the injection lance and a first side of the connection flange, and
- a hose barb coupled to the connection flange and protruding from a second side of the connection flange, wherein the conduit assembly is coupled to the hose barb, wherein the conduit assembly and lance assembly are fluidly connected.
An injection system for connection between a fluid tank and a process line, the injection system comprising:
- a pump assembly configured to attach to the fluid tank;
- an injection assembly configured to be fluidly coupled to the pump assembly and including:
- an injection lance having a flange with first and second sides and a stem extending from the first side of the flange, and
- a first seal configured to be arranged between the first side of the flange and the process line, wherein the process line is configured to receive the stem of the injection lance;
- and
- a conduit assembly configured to fluidly connect the pump assembly and the injection assembly.
