Abstract
A process for treating methane-containing natural gas is provided which comprises: i) converting methane to methanol at or near a site of natural gas production; ii) transporting the methanol to a refinery remote from said site of production, said refinery producing ethylene and propylene and comprising an alkylation unit which can utilize a propylene feed; and iii) converting said methanol to gasoline boiling range fuel product and petrochemicals, including ethylene, propylene, butenes and xylenes.
Claims9
A process for producing ethylene, propylene and gasoline boiling range fuel product, the process comprising the steps of
- i) providing methanol to a refinery comprising a FCC unit and an alkylation unit;
- ii) producing ethylene, propylene and butene in the FCC unit;
- iii) isolating ethylene and propylene produced in the FCC unit from butenes produced in the FCC unit;
- iv) converting the methanol to olefins comprising ethylene, propylene and butenes;
- v) isolating butenes produced in the step of converting from ethylene and propylene produced in the step of converting;
- and
- vi) supplying butene produced in the converting step and butene produced in the FCC unit to the alkylation unit to produce the gasoline boiling range fuel product.
