Mr Lalit Vashishta of M/s Diva Envitec Europe Ltd will be presenting a paper on "SLURRY OIL FILTRATION USING SS316 - AS MEMBRANE FOR REMOVAL OF CATALYST PARTICLES IN FLUIDISED CATALYTIC CRACKING UNIT"For the past 15 years Oil Asia with the technical support of noted oil sector expert from national and multinational oil companies is organising IORS-2009 International Exhibition along with India Oil & Gas Review Summit. The IORS-2009 International Exhibition brings in the Decision makers, Technologists, Buyers, Innovators, Scientists, Professionals, Senior Executives and Service Providers on a common platform to disseminate technology before over 700 delegates, invitees, guests, participants, visitors and the numerous exhibitors. The participants from over 15 countries are expected to project and display the skills and capabilities in services and technology.
The key driver and motive for removing the catalyst fines and particles in an FCC is for the purpose of upgrading product fuel oils or upgrading feedstock for production of carbon black or other products. Removal of catalyst fines reduces the wear of downstream components due to the abrasive nature of the particles, prevents settling and sludge formation in slurry oil storage tanks as well as removes the concerns over the hazardous waste classification of catalyst-containing tank sediments.
Fuel oil vendors for years have used storage tanks, barges, and chemical agents to settle catalyst material from oil products, which leaves behind large volumes of toxic sludge in the containment which eventually needs to be cleaned in an environmentally safe manner. Today these practices are closely monitored by government officials and accordingly waste treatment of this sludge has become expensive. Filtration of the slurry oil at the refinery can significantly reduce these costs by returning the catalyst fines back to the reactor.
This paper highlights the process of slurry oil filtration and selection of filter media. The use of the rolled and welded sheets of stainless steel sintered powder filters or multi-layered mesh type laminate filters have distinct drawbacks. The paper highlights the use of asymmetric Powder metallurgy as compared with existing technologies, which will resolve many issues in the FCC unit Slurry oil filtration.
