Normally clay downstream of extraction lasts a long time. Units utilizing glycol can damage the clay easily if there is any glycol carry over. SulfolaneTM generally does not damage clay. For the glycol processes, it is possible to use a scrubber to reduce glycol carry over to the clay. This is a standard requirement of UOP’s CaromTM units but the older UdexTM and Union Carbide TetraTM units could benefit if this is a problem for them.
