Abstract
The invention relates to a process for modifying tanker ships. More specifically, the invention is directed to a process for modifying a non-methanol-carrying tanker to carry a methanol cargo destined for a methanol to olefin reaction system. The process includes providing a tanker having one or more holds that previously stored a non-methanol material. The process includes one or more of the following steps: (1) cleaning the holds of the crude/naphtha-carrying tanker to remove residual deposits, wherein the holds previously stored a non-methanol material; (2) providing a fire suppression system specially designed to prevent methanol fires; and (3) replacing methanol intolerant pump seals and flange gaskets in the tanker with methanol resistant seals and gaskets.
