Objectif Development of an engineering design package to demonstrate the technical feasibility and economic viability of an offshore process plant producing methanol from associated gas feedstocks using a unique gas reformer process patented by Stone & Webster.Economically the study for the full scale plant showed that where an oil field of marginal size with associated gas located subsea in an area where development of the field would not normally be contemplated because pipelining of the product ashore is uneconomic, the production of methanol by method is viable and economic.The use of this novel form of reformer becomes more interesting where legislation precludes the flaring of associated gas, enabling the field to be developed and the gas used.Because of the nature of the seas and weather conditions that may be encountered in remote areas, the study shows that storage of the separated oil and produced methanol in thanks within the carrying vessel is a large factor in deciding what sort of ship should be used to carry this process offshore.Since the plant items used will operate in all sea motions except the most extreme, which may be encountered for only 2 to 3% of the year, then it is possibly best mounted on a large (100,000dwt or larger) specially built tanker type ship to provide adequate product storage to await the return of shuttle tankers transporting product to shore.Before a scale plant is contemplated it is essential that a small scale demonstration unit as outlined in this package be built to verify the technology, the Convective Reformer design and integration with a gas turbine.The scope of the project covers two basic areas:- Preparation of a basic engineering package for a 1,000 tonne per day offshore methanol plant incorporating the Stone & Webster Convective Reformer mounted upon monohull and semi-submersible carrying vessels.Schemes have been developed using the Zapata FPS 5000 and the GVA 5000 semi-submersible vessels. The monohull vessel used is the Worley Oil Patch S STB 48 which is a single hull vessel mounted on a ballasted, submerged pontoon, thus improving stability over normal ship motions- Preparation of the pre-detailed engineering design of a small scale (one-tenth full size) plant to demonstrate the operability of the Convective Reformer concept to be shore-based within the confines of an existing chemical complex where suitable feed gas and utilities are available for connection, and where the produced syngas can be used commercially.
