- the ribs 100 extend crosswise or transversely to the vertical members 98.
- the ribs 100 provide additional structural integrity for the cage 90 and also aid in holding the coupon 46 within the cage 90. While the figures show the use of three ribs 100, it should be appreciated that this is not to be limiting, and the exact number and placement of the ribs 100 may vary. For example, while the ribs 100 are shown to extend generally perpendicular to the vertical members 98, it should be appreciated that, in some aspects of some embodiments, the ribs 100 may cross at angles greater or less than 90-degrees.
- the number of ribs is also calculated and designed in order to fix and hold the coupon, such as more or fewer ribs when the size of the coupon changes or is different than that shown herein.
- the ribs 100 may also be tapered similarly to the entrance 92, such as to mitigate the accumulation of a liquid thereon.
- the coupon holder 80 as shown and described provides advantages for the cleaning of coupons 46, such as via the automated process and system included herein.
- the coupon holder 80 provides a structurally secure device to hold a coupon 46 during the cleaning.
- the configuration of the holder 80 is such that the coupon will be fully exposed to the cleaning liquids and drying of the system, while controlling the coupon.
- the coupon is held very well so that it can be cleaned up and will not be damaged in the process of cleaning.
- the holder 80 will prevent adjacent coupons from hitting one another, which preserves the structure and increases the life of a coupon.
- a hanger 60 may be used with the cleaning system 10.
- the hanger 60 is shown throughout the figures as being used to hang multiple coupons in the drying rack 26 or in one of the liquid bins.

- the hanger 60 may include notches 68 at opposite ends of the body, with the notches configured to connect to the various racks and bins of the cleaning system 10.
- the notches 68 are shown to be generally downward oriented concave members and c-shaped. This shape allows the notches to be positioned at edges of the racks or bins with the racks or bins positioned within the notches.
- the hanger 60 may comprise a rigid material, such as steel or the like, which provides structural rigidity during this time, as the hanger 60 will be supporting itself on the racks or bins.
- a rigid material such as steel or the like, which provides structural rigidity during this time, as the hanger 60 will be supporting itself on the racks or bins.
- generally any configuration to allow the hanger 60 to be connected to or positioned on a bin or rack should be considered to be a part of the present disclosure.
- Additional features of the hanger 60 include a plurality of slots 70 extending downward from the top 64 of the body 62.
- the slots 70 do not extend all the way through the bottom 66 of the body 62, though.
- the slots 70 have an opening 72 and a bottom 74.
- the shape of the slots 70, including the opening, are configured to allow a portion of the holder 80 to be housed during connection between a hanger 60 and a coupon holder 80.
- the slot 70 is configured to receive the t-shape.
- the neck 84 of the holder 80 is narrower than the t-shaped portion, the neck and body of the holder (including the cage and coupon itself) will be below the hanger body 62. This allows the holder 80 to hang from the hanger 60.
- the hanging of the holder and coupon will allow the coupon to be submerged into the solutions and also to be dried via the rack 26.
- a number of coupons 46 in holders 80 are hanging from a hanger 60.
- the exact number and placement of the holders 80 is not to be limiting, and the hanger 60 could be configured to hold as many or as few as desired.
- there are slots 70 on both sides of the hanger to maximize the number of coupons that can be cleaned at a time.
- the use of the holder with cage will prevent the coupons from contacting one another during the cleaning process, which limits contamination of the coupons.
- the hanger 60 includes a connection 76.
- the connection 76 is an extruded portion that extends upwardly away from the top 64 of the hanger body 62.
- the connection may take generally any configuration, but is used as a connection to a robotic arm 18 of the cleaning system. The arm 18 is able to connect to the connection 76 to move the hanger 60 and associated coupon 46/holder 80 combinations through the cleaning and drying process.
- the use of the hanger 60 provides the advantage for the system to be able to clean more coupons at the same time, which further increases the efficiency of the cleaning process with the automated system.
- Robot arm takes the coupon hanger assembly from the rack.
- ⁇ Robot moves right and will stop above acid case. If the coupon material is iron or stainless steel, it will be stop above hydrochloric acid case. If the coupon material is copper or brass, it will be stop above sulfuric acid case.
- Ultrasonic will start to clean coupon to remove the surface corrosion. Duration is about 30s ⁇ 5min and it can be set up.
- ⁇ Robot will take the coupon to the alkali case and put the coupon into the sodium bicarbonate solution about 1-minute to neutralize the acid on the surface of coupon while ultrasonic is working. The duration also can be set up.
- ⁇ Robot will take the coupon to the water case and put the coupon into the water about 1- minute to remove residues on the surface of coupon. The duration is also can be set up.
- ⁇ Robot will take the coupon to the water case and put the coupon into the ethanol about 1-minute to remove water on the surface of coupon. The duration is also can be set up.
- Robot will take the coupon hanger back to the rack after the cleaning process finished and the electrical fan will work to dry it. Robot will take another coupon hanger to go through the cleaning process until all coupon hangers are taken.
- Waste solution will be discharged automatically.
- Such improvements include, but are not limited to, coupon analysis efficiency, data accuracy improvement, improved safety, commercialized cleaning, and improved efficiency of inhibitor coupon cleaning.
