Oiltanking has been active in crude oil storage since 1972 and is one of the largest independent operators for crude oil storage in the world. Oiltanking has operations in 23 countries with a total storage capacity of 20 million m3 in five continents.
Oiltanking was interested in trying HCR™ due to the fact it was advertised as a hydrocarbon-based contact agent not requiring special equipment or man entry to liquefy the sludge in oil storage tanks.
The tank we needed to clean was a tank we were converting from storing crude oil sludge to gasoline so we needed a product that would do a thorough job cleaning the tank of sludge. HCR™ was an excellent product for this.
We also found it interesting that HCR™ does not affect the specifications of the oil, nor require any additional processing of the sludge or temperature control.
Just add HCR™ and circulate it with the sludge.We found HCR™ did a great job liquefying the sludge converting our sludge to saleable crude oil. I have not seen a product to liquefy crude oil sludge that is this simple to use and this effective.

Centurion Pipeline L.P. is a common carrier pipeline operator with approximately 2,900 miles of pipelines extending from southeast New Mexico across the Permian Basin of west Texas to Cushing, Oklahoma. The system has a throughput capacity of approximately 720,000 barrels per day.
The tank was initially pumped down and landed on low legs. The 30”by 60” roof man-way removed to conduct a visual inspection. Upon removal of the roof manway there was five to six thousand barrels of non-pumpable BS&W in the tank.
Prior experience with this type of BS&W and the cost associated with removing the material and cost of disposal we decided to try to treat the material. The five thousand barrels of material are now merchantable crude that can be pumped into our system.HCR™ treatment delivered the following results:
• Recovered 5000 bbls crude versus disposing
• Reduced manpower 50%
• Reduced disposal 99%
• Reduced safety risk
• Reduced environmental risk
• Generated revenue from recovered crude
• Cleaned tank extremely well, reduced post clean up 75%
• Reduced cost of clean out 75%

HCR™ in Oil Tankers
HCR™ is also optimised for use in crude oil tankers, having seen successful deployment aboard a Shell oil company barge, granting the recovery of over 3000 bbls of saleable product. Premixed in a shore battery, a small quantity of HCR™ can be added to a crude oil payload prior to shipping. In-transit, the natural agitation provided by ocean waves mixes the payload while the HCR™ works to remove sludge, incorporating the constituent hydrocarbons into the payload. The process greatly reduces diminished capacity within vessel compartments, allowing the offloading of sludge as a saleable product. As a result, demurrage charges and refinery fees for processing sludge from compartments are also reduced.

HCR™ in the Mardi-Gras Pipeline
HCR™ has also seen successful application to sludge deposits in oil pipelines, including BP’s Mardi-Gras pipeline, located in the Gulf of Mexico. Addition of a precalculated volume of the treatment in front of a pig prior to launch removes sludge accumulations in the line; increasing the working diameter, reducing pressure, and improving flow rate. Incremental additions of the treatment can be applied as required, to restore complete functionality to blocked or obstructed lines. Proactive treatment keeps pipelines clean while reducing corrosion from moisture and paraffin build-up along the bottom of the line.
