Claim:
A process for shipping methanol and converting the methanol to olefin product, comprising the steps of: a) loading methanol into a hold of a ship; b) transporting the methanol to a location geographically distinct from where the methanol was loaded into the ship; c) withdrawing at least a portion of the methanol from the hold; d) adding a blanketing medium to the hold; e) heating the withdrawn methanol to form a vapor stream that comprises a majority of methanol and a liquid stream that contains metalloaluminophosphate molecular sieve contaminants; f) separating the vapor stream from the liquid stream; and g) contacting the separated vapor stream with metalloaluminophosphate molecular sieve to convert the methanol to olefin product wherein the metalloaluminophosphate molecular sieve catalyst contaminants include at least one metal selected from the group consisting of iron, sodium and potassium.
