London Chemicals & Resources Catalyst Removal & Reprocessing and Supply of Chemical Raw Materials
London Chemicals & Resources specialize in the removal and reprocessing of spent refinery catalysts, oil slurry and fly ashes and contaminated ceramic balls. We also sell and distribute inorganic chemicals.
We offer vanadium and molybdenum salts for use in Stretford (H2S removal) and Benfield (CO2 removal) processes as well as for the production of fresh refinery catalysts. The company operates worldwide, dealing with markets directly and via a network of agents. We maintain stocks in the Far East, Europe and the USA.
The chemicals we offer include:
- Cobalt: cobalt acetate, cobalt carbonate, cobalt manganese bromide, cobalt oxide
- Molybdenum: ammonium molybdate, molybdenum trioxide, sodium molybdate
- Nickel: nickel oxide, nickel sulphamate, nickel sulphate
- Potassium: potassium metavanadate, potassium nitrite
- Tungsten: ammonium paratungstate, tungstic acid, tungsten trioxide
- Vanadium: ammonium metavanadate, ammonium polyvanadate, potassium vanadate, sodium vanadate, vanadium pentoxide, vanadyl sulphate
REMOVAL AND REPROCESSING OF SPENT CATALYSTS
London Chemicals is experienced in the removal and reprocessing of spent and secondary forms of non-ferrous, high metal-containing materials. We purchase spent refinery catalysts (e.g. HDS and RDS types) and ship these to Taiwan for reprocessing at Full Yield Industry – our partners. This company, founded in 1981, has ISO9001:2000 and ISO14001 certification and full permission with a license from the Taiwanese government for this type of work.
OIL SLURRY AND FLY ASHES REPROCESSING
Apart from spent catalysts, we also reprocess oil slurry and fly ashes as well as other waste type materials that have high cobalt, molybdenum, vanadium nickel and tungsten content. Many of these are then returned to the industry in the form of fresh raw materials, such as vanadium pentoxide and molybdenum trioxide.
CONTAMINATED CERAMIC BALLS – REPROCESSING AND RESALE
Another area of expertise is the reprocessing and resale of contaminated ceramic balls from catalyst beds – these are cleaned and separated into different sizes before being resold as a more environmentally-friendly, economic alternative. Full Yield are aware of the environmental concerns attached to processing these materials and a large percentage of their overall operating cost is spent keeping equipment compliant and employees up-to-date with all the latest EPA regulations.
Typical feedstocks include:
- CoMo and NiMo types of spent catalyst
- Heavy oil (H-Oil) fly ash
- Nickel catalysts
- Tungsten catalysts
Full Yield has already been approved by, and in many cases audited, for the successful reprocessing of materials from companies including: Bapco, Caltex, Chevron, China Petroleum Corporation, Dupont Petrochemicals, Esso, Exxon-Mobil, Formosa Plastics, New Zealand Refinery and Shell.
