ABOUT THE PROJECT Amazon Filters have recently completed a major contract worth over $2m for the provision of filter vessels and cartridges for an Offshore System being supplied by Veolia. Amazon has many years of experience in developing, supplying and supporting a variety of equipment for the international Oil and Gas market and this expertise was put to good use in the specifying the optimum systems for this project. The scope consisted of large glass flake lined steel housings with 25Cr SDSS internals and a quick opening closure. This construction offered protection from corrosion by the filtered seawater, and easy access to the inside of the vessels to facilitate quick filter replacement and all of this without the additional expense of an all alloy construction.
PROJECT CHALLENGES The filter systems are being integrated into two SRP (Sulphate Reduction Process) packages to provide high quality injection water on two FPSO (Floating Production Storage and Offloading) facilities operating deep-water offshore South America. Six 2m diameter vessels were supplied and configured in such a way to allow change out of filter cartridges without compromising the required flow of water. With the experience to respond to the constantly evolving requirements typical of Oil and Gas projects Amazon was able to identify in advance the many potential technical issues that would need to be overcome and therefore met the challenging delivery schedule necessary for this project.
Each housing contains over 80 high flow filter cartridges and is rated for 857 m3/h flow of seawater. The filter cartridges used in the system were from Amazon’s SupaPleat XP Extended Life range, manufactured from polypropylene and supplied in the large diameter high flow format. The cartridge design chosen for this operation has been refined and optimised on similar applications over a number of years to ensure the required filtrate quality is achieved by offering a high contaminant retention capability, while at the same time avoiding premature blinding problems that make seawater filtration challenging. Protection of reverse osmosis membranes for desalination or sulphate reduction processes is of crucial importance to ensure long membrane life and low down-time for cleaning. Amazon’s wide range of absolute rated spun and pleated cartridges have been time proven in critical applications worldwide and their use helps guarantee the filtrate quality meets the membrane’s water feed specification. Fitted inside an Amazon designed filter housing they provide a high quality and low maintenance solution suitable for 25 years or more of operation. Full support services are supplied by Amazon’s expert filtration engineers and laboratory facilities during the life of the plant. Many operators have benefitted from our ability to optimise the whole system thus minimising running costs and maximising production volumes.
