| titleOfInvention | process for separating a multicomponent hydrocarbon stream and ethylene oligomerization process |
| abstract | abstract "process for separating a multi-component hydrocarbon stream and ethylene oligomerization process" a process (10) for separating a multi-component hydrocarbon stream (26) comprising ethylene, at least one polymer and other components includes submitting the multi-component hydrocarbon stream the flash in the first flash stage (12) from an elevated pressure of more than 30 bar(a) and an elevated temperature in the range of 150°c to 185°c at a flash pressure in the range of 10 bar(a) to 30 bar(a), producing a first steam head product containing ethylene (28) at a pressure in the range of 10 bar(a) to 30 bar(a) and a first flash phase bottom product (30.1 ) which includes some ethylene, the at least one polymer and some of the other components. the flash pressure and elevated temperature of the multi-component hydrocarbon stream (26) are selected so that the first flash phase bottoms product (30.1) has a concentration of at least one polymer of less than 5% in bulk to make the viscosity of the first flash stage bottom product (30.1) at the temperature of the first flash stage bottom product (30.1) in the first flash stage (12) less than 1000 cp at a shear rate of 1 per second. at least a portion of the first flash phase bottoms product (30.1) is heated to a temperature in excess of 150°C to form a heated first flash phase bottoms product (30.2). a recycle portion (30.3) of the first heated flash phase bottoms product (30.2) is combined with a multi-component hydrocarbon stream (26) which is at a bottom temperature of 150°C prior to blending. with the recycle portion (30,3), to thereby heat the multi-component hydrocarbon stream (26) to the elevated temperature in the range of 150°C to 185°C. at least a portion (32) of the first flash stage bottoms product and the first ethylene-containing vapor head product (28) is taken from the first flash stage. |
