Abstract
An injection-molded load line connection spillage container for catching and retaining liquid spilled when liquids are pumped between storage tanks and tankers provides an injection-molded reservoir and an injection-molded cover attached to the reservoir by hinges. Reinforcing ribs molded into the reservoir provide strength and ruggedness without the need for reinforcing steel collars and saddles. Gussets molded into the reservoir hinge brackets ensure repeated stresses produced by energetic opening of the cover does not result in failure of the hinge brackets. An optional load line mounting assembly permits secure mounting of the load line container directly onto the load line. An optional cleanout assembly provides a valved suction line for removing retained spillage, and an optional sampling assembly provides a valved sample line for sampling the liquid being transferred.
Description
- The present application is a continuation of U.S. patent application Ser. No. 12/660,260 for Load Line Connection Spillage Container filed Feb. 23, 2010 which is a continuation of U.S. patent application Ser. No. 12/259,577 for Load Line Connection Spillage Container filed on Oct. 28, 2008 now U.S. Pat. No. 7,673,658.
- 1. Field of the Invention
- This invention relates generally to containment of oil, waste, and chemical spills, and more particularly, to a container for containing spillage at a load line connection. As used herein, the terms “load line connection spillage container,” “load line spillage container,” and “load line container” refer, interchangeably, to applicants' invention.
- 2. Discussion
- Environmental concerns require containment of oil, waste, and other chemical spills from pipelines, storage tanks, tanker trucks, and railroad tankers. Pollution occurring when liquids are transferred between storage tanks and tanker vehicles through transfer lines is a continuing concern. Although transfer lines occasionally fail, leakage more typically occurs where the line from the tanker truck or railroad tanker attaches to the storage tank unloading line. The transfer lines are normally equipped with quick connect fittings, but spillage can occur during connection and disconnection of the transfer lines.
- U.S. Pat. No. 5,313,991 is directed to an oil and waste line connection spillage containment apparatus (also referred to herein as a “load line container”) constructed from non-corrosive and rustproof materials. A substantially cylindrical container has two openings for receiving oil and waste loading and unloading lines therein. The lines are connected within the container. A circular cover encloses the container and is fastened and unfastened from the container using a pair of L-shaped members. Any oil and waste spilled from the connection is removed from the container when the lines are disconnected. In the alternative, a removal line with an auxiliary valve is used to withdraw the oil and waste from the container through the loading line. When the unloading line is removed from the opening in the container, a vented plug is inserted into the opening.
- U.S. Pat. No. 5,647,412 is also directed to an apparatus for containing oil and waste spillage at a line connection. A load line container has opposed sidewall openings which receive loading and unloading lines, respectively, which are coupled within the container. Any spillage from the ends of the lines and the line connection is retained within the container. A lid closes the top end of the container when the unloading line is removed from the apparatus. With the unloading line removed from the container and the lid closed, an extension member attached to the lid covers the sidewall opening that is used for receiving the unloading line within the container.
- Load line containers according to U.S. Pat. No. 5,647,412 made from fiberglass, medium density polyethylene, and high density polyethylene have been marketed in the United States and abroad. These load line containers have capacities, i.e., the maximum volume of spillage to be contained, of up to 35 gallons. The weight of the apparatus itself is nominal, but the combined weight of transfer lines and steel couplings associated with the unloading line and transfer lines is significant. In addition, the oil and waste spillage contained within the apparatus can weigh up to about 250 pounds. Finally, the apparatus is typically deployed in remote locations requiring a rugged product able to withstand rough treatment. In the past, steel collars, steel plates, and steel saddles have been used to strengthen the load line containers. It would be highly desirable to have a load line container which is sufficiently rugged for oil field application without the necessity of reinforcing steel collars, plates, and saddles.
- What is needed is an injection molded load line container having a structure which is inherently strong and rugged, thereby eliminated the need for reinforcing steel collars, plates, and saddles.
- An injection-molded load line connection spillage container for catching and retaining liquid spilled during transfers of liquids between storage tank and tankers provides an injection-molded reservoir and an injection-molded cover attached to the reservoir by hinges. Reinforcing ribs molded into the reservoir provide the strength and ruggedness required for oil field applications. Gussets molded into the reservoir hinge brackets ensure repeated stresses produced by energetic opening of the cover does not result in failure of the hinge brackets. An optional load line mounting assembly permits secure mounting of the load line container directly onto the load line. An optional cleanout assembly provides a valved suction line for removing retained spillage, and an optional sampling assembly provides a valved sample line for sampling the liquid being transferred. An optional main line valve contained within the load line container provides secure control of transfer between the storage tank and the tankers. An optional flow meter assembly, either in-line or clamped to the exterior of a transfer line, permits measurement of the volume of liquid transferred.
- An object of the invention is to provide a rugged corrosion-resistant and wear-resistant container for collecting spillages at load line connections.
- Another object of the invention is to provide a load line connection spillage container with a built-in cleanout assembly for removing captured liquids from the container.
- Another object of the invention is to provide a load line connection spillage container which can endure the wear and tear associated with oil field operations.

- Referring generally to
FIGS. 1-3 , aload line container 20 has a reservoir cover 22 (also referred to herein as a cover) attached to areservoir 24 by hinges 26. Typically, theload line container 20 is mounted on a load line (not shown) from a storage tank (not shown). Another line (not shown) extends from a removal source such as a tank truck (not shown) for connection to the loading line within theload line container 20. Thus theload line container 20 provides a point of connection between the loading line (from the storage tank) and the unloading line (from the tank truck). It will be understood by one skilled in the art that, while the present invention is described in the context of transfer of liquid from a storage tank to a removal source such as a tank truck, liquids are also routinely transferred from tank trucks to storage tanks. Thus, whereas the term “loading line” is used herein, for ease of illustration, to indicate the line attached to the storage tank and the term “unloading line” is used, for ease of illustration, to indicate the line attached to a tank truck or other removal source (e.g., a rail car), both “loading lines” and “unloading lines” are liquid transfer lines facilitating flow either to or from a storage facility. - Still referring to
FIGS. 1-3 , thereservoir cover 22 is generally circular with acentral dome portion 28 and alip 30. Ahandle 32 adjacent thelip 30 is generally centered over a downwardly projectingarcuate member 34.

Atransfer line channel 60 located in the frontupstanding wall portion 52 is sized to receive a transfer line (not shown). Aload line throughway 62 located in the rearupstanding wall portion 54 provides a location for attachment of a load line mounting assembly 100 (SeeFIGS. 7-8 ). Theupper end portion 50 of thereservoir 24 terminates in an integrally molded J-shapedlip 64 having asidewall portion 66 and arollover portion 68.Lip gussets 70 spaced about the circumference of the openupper end portion 50 between thesidewall portion 66 and therollover portion 68 strengthen the integrally molded J-shapedlip 64 and the openupper end portion 50 of thereservoir 24. - Referring now to
