NNPC carbon black unit has been operating off-and-on for the last year

Last week, this blog reported the news that Nigeria’s House of Representatives had advised the Nigerian National Petroleum Corporation (NNPC) to shut down its refinery in Warri due to emissions from its carbon black unit. Prior to this news, Notch believed that the carbon black unit had been shut down since about 2005. Based on information from an industry source, Notch has heard that the carbon black unit has been producing for about one year, but that production has been quite sporadic due to persistent mechanical problems with the unit.
