WO/2015/024540 METHOD FOR IMPROVING THE TRANSPORTABILITY OF HEAVY CRUDE OIL||WO||26.02.2015|
||PCT/DE2013/100305||WAGNER, Ulrich||WAGNER, Ulrich|
The invention relates to a method for improving the transportability of heavy crude oil. Proceeding from the disadvantages of the known prior art, a method is to be devised with which a viscosity-reducing agent is provided that can be produced inexpensively, can be added to the heavy crude oil with little effort, and does not lead to disadvantageous effects during the subsequent refining process into conventional gasoline. This is achieved in that a quantity of 10 to 40 wt.% of crude oil is branched off from the transported heavy crude oil in the region of a petroleum deposit and converted in situ into a water-containing hydrocarbon mixture with a chain length of predominantly C4 to C12, said mixture not containing oxygen-containing hydrocarbon compounds, via intermediate steps, a syngas production, a methanol synthesis, and a production of a dimethyl ether/methanol/water mixture. The hydrocarbon mixture is added to the heavy crude oil after a degassing process, and a light crude oil obtained from the heavy crude oil is transported to a refinery via lines. During the subsequent refining process of the light crude oil into conventional gasoline, the hydrocarbons contained in the water-containing hydrocarbon mixture become a part of the produced gasoline quantity.

||PCT/DE2013/100304||WAGNER, Ulrich||WAGNER, Ulrich|
The invention relates to a method for improving the transportability of heavy crude oil. Proceeding from the disadvantages of the known prior art, a method is to be devised which can be carried out with little effort and without special safety precautions. As an additive, a water-containing hydrocarbon mixture with a chain length of predominantly C4 to C12 is used, said mixture not containing oxygen-containing hydrocarbon compounds. The hydrocarbon mixture is produced in parallel in the region of a petroleum deposit from natural gas and/or an associated gas and from a heavy crude oil sub-quantity which has been branched off. In the process, a first syngas and a second syngas are produced as intermediate products which are mixed in a mixer and then compressed. Subsequently, the syngas is catalytically converted into methanol, and the methanol is converted into a methanol/water mixture (crude methanol) by a condensation process and then catalytically converted into a dimethyl ether/methanol/water mixture. The water-containing hydrocarbon mixture with a chain length of C4 to C12 is produced by a dehydration process, said mixture being either untreated or added to the heavy crude oil after a degasification and/or dewatering process. A light crude oil is obtained from the heavy crude oil, and the light crude oil can be transported to a refinery via lines and increases the produced quantity of gasoline by the hydrocarbons contained in the water-containing hydrocarbon mixture during the subsequent refining process of the light crude oil into conventional gasoline.
