Krish: We do not profess to be experts in this area, however, mercury has a potential SCC effect on aluminum, which is an issue with aluminum cold boxes on the back end of an olefins unit. We can't provide an acceptable level of mercury with respect to corrosion in a refinery, except to say that we haven't heard of it being an issue. David Hendrix The Hendrix Group Inc.

Krish Source : Oil & Gas Development - Onshore (Pollution Prevention & Abatement Handbook - World Bank Group - 1998 Total toxic metals permitted in Crude Oil Processing : 5 mg/ litre (Toxic metals include the following namely - Arsenic, Beryllium, Cadmium, Chromium, Copper, Lead, Nickel, Mercury, Selenium, Silver,Thallium, Vanadium and Zinc,). Total Waste water Management - Contaminants permitted in Crude Oil Processes Cadmium: 0.6 mg/litre Chromium: 2.3 mg/litre Copper : 0.4 mg/ltre Nickel : 0.4 mg/litre Lead: 0.2 mg/litre Mercury: 0.1 mg/litre You should recognize the harmful effects of Mercury from SCC on various metals (S.S, Cu, Al to name a few) in service. Also look from pollution control aspects using Mercury in crude oil proecessing. Mercury is harmful for human handling. Please also refer the following documents if you have access; API - 1989 - API Environment Guidance Docuemtn Washington - Onshore Waste Management in Exploration & Production Operations UK Document 1992 - Her Majesty's Inspection docuement - Chief Inspector 's Guidance to Inspectors , Environemtn Protection Act 1990 - Process Guidance Note IPR1/16 : Petroluem Processes On-shore Production - Her Majesty's Stationeray Offcie London Trust this is of help to you C.V.Srinivasan Nishi Engineers Pvt Ltd India Nov 18, 2005 E-mail: nishi@vsnl.com >We are planning to process(short term)with mercury content >crude?What is the acceptable level of mercury in the >crude?What will be deterimental effect on higher mercury >level in metallurgy like copper,brass, stainless etc. > >regards,
