TH24400B - Process for removing mercury from hydrocarbons. - Google Patents

Abstract

DC60 (17/05/44) removes mercury from crude oil, natural gas condensation and other liquid hydrocarbons by removing colloidals. Mercury and solids with pre-absorbed mercury And then adjust Hydrocarbon conditions with organic or inorganic compounds with at least one sulfur atom forming Reaction to mercury Sulfur compounds react with dissolved mercury contaminated with Hydrocarbons until they form a mercury-containing partition, which is then eliminated from hydrocarbons to produce Purified products containing reduced mercury content should be used as conditioning agents. Organic sulfur, such as dithiocarbamate or isobutylene, which has been sulphurized Eliminate mercury from crude oil, natural gas condensation and other liquic hydrocarbons by removing colloidals. Mercury and solids with pre-absorbed mercury And then adjust Hydrocarbon conditions with organic or inorganic compounds with at least one sulfur atom forming Reaction to mercury Sulfur compounds react with dissolved mercury contaminated with Hydrocarbons until they form a mercury-containing partition, which is then eliminated from hydrocarbons to produce Purified products containing reduced mercury content should be used as conditioning agents. Organic sulfur, such as diethiocarbamate or isobutylene that has been sulfurized.

Claims (4)
