Willowchem Technology (Ireland) Limited are now offering a Positive Material Identification Service as part of the wide array of services that the company already provides.

Details can be found under Services - Positive Material Indentification Services.

Over the past year or so Willowchem Ireland has progressed further and has polished a wide variety of vessels ranging from 25 litre to 25,000 litre.  These projects have been very successful and our customers are extremely happy with the results.  This has lead to the company securing further projects from similar industries and also the addition of new cliental to our customer base.

We are currently in the process of completing a number of degreasing and electropolishing projects for a wide variety of clients.

Below are images of 2,500 litre Vessels that were eletropolished at our premises recently..

There were 3 no. Vessels completed in total.

The chemicals used to complete this were Willowchem 60, Willowchem 61 and Willowchem BioPass.

CARBON FILTER TANKS BEFORE CLEANING

Over this progressive period many of the projects taken on board included the internal electropolishing of relatively small pressure vessel of between 50 – 500 litres. With well documented procedures and controls, including pre cleaning and post passivation treatments, Willowchem Ireland found their past experience within the Pharmaceutical industry to be priceless with the knowledge of the high level demands expected, especially with written procedural documentation.

Willowchem Ireland Limited then moved onto even larger vessel of approximately 1000 litres

After cutting their teeth on over 25 units, Managing Director Billy Curtin decided, in August, that it was time to progress to the next level by taking on a project with 2 vessels of 5000 and 6000 litres repectively. Whilst not being afraid to tackle these larger vessels with the assistance and consultation of associates, the project was even more testing by the fact that the vessels were already completely assembled and the time allocated to process them was over a weekend. Delivered Friday evening and required back to the customer by Monday lunchtime, the challenge was taken on board and the commitment given with only a week’s notice, of the vessels arriving.

Engineering details of the fixturing concept were speedily implemented and the complete design was manufactured within 4 days. A detailed method statement and process procedure was drafted and all necessary safety equipment sourced, being onsite prior to the expected delivery. All the raw materials such as product chemistries, applicators, cables, cathode and Busbar materials were already onsite and the loan of an adjustable bed rotating rollers system was secured during this short notice period. The quality of fixture and jigging build makes the process a whole lot easier when manufactured with precision.

Unloading and positioning of the vessels for each step was carried out with precision as the wet processing area in Willowchem Ireland is fitted with a modern, fully motorized 5 tonne over head hoist system and the staff rigging and banksman skills are second to none.

After degreasing with Willowchem Cleaner 61, the nimble athleticism of the staff and operators was required to fit a cathode assembly fixture at each stage of the electropolishing procedure. In these difficult conditions, the conscientious and dedicated nature of the workforce ensured that great care was taken at each stage not to mechanically damage both before and after processing.

Finally the vessel was positioned on it legs in the upright position to desmut and passivated with Willowchem 70, followed by thorough rinsing and allowed to naturally dry with the assistance of clean compressed air.

The exercise was a complete success with the first vessel collected Sunday afternoon and the second Monday afternoon. The customer was fully satisfied with both the surface finish and service and has promised more large vessel projects, already in hand in the near future.
