Abstract
Oil processing apparatus for the treatment of a mixture containing oil and other constituents. The apparatus comprises two types of separators arranged to co-operate together, the first separator (22) being of the type capable of handling a mixture containing a relatively high percentage of oil and the second separator (26) being of the type capable of handling mixtures containing a relatively low percentage of oil so that substantially full separation of the oil and other components can be achieved. There is also provided a system for recovering oil from a subterranean reservoir wherein apparatus which may be of the type described above is at least partially located underground.
Claims14
Oil processing apparatus for the treatment of a mixture containing oil and other constituents, the apparatus comprising means for enabling the minimizing of the weight of said apparatus and the floor space required thereby, the apparatus including a primary treatment section which includes one or more primary cyclone separators (22) each having inlet means and first and second outlet means, said primary cyclone separator(s) being of the type capable of handling a mixture containing a relatively high percentage of oil and of separating the mixture into first and second components which are discharged from said first and second outlet means respectively with said first component being relatively highly concentrated in oil and said second component being of relatively low concentration, the apparatus further including a secondary treatment section which includes one or more secondary cyclone separators (26) the or each separator including inlet means operatively connected to said second outlet means of said primary cyclone separator(s), said secondary cyclone separator(s) further including first and second outlet means and being of a type capable of handling mixtures containing a relatively low percentage of oil and of separating the mixture received from said second outlet means of said primary cyclone separator(s) into first and second components which are discharged from said first and second outlet means of said secondary cyclone separator(s) respectively, said first component containing substantially the remainder of the oil and said second component being substantially oil free.
Oil recovery system for recovering oil from an underground reservoir (82) from which a mixture containing oil and other constituents can be discharged, the system comprising a line disposed in a cavity (80) between the reservoir and the ground surface and oil processing apparatus including means for enabling the minimizing of the weight of said apparatus and the floor space required thereby, the apparatus at least partially separating the oil from the other components in the mixture, said apparatus being operatively connected to said line and at least part of said apparatus being disposed below the ground surface within said cavity, said apparatus comprising:
- a primary treatment section which includes one or more primary cyclone separators (22) each having inlet means and first and second outlet means, said primary cyclone separator(s) being of the type capable of handling a mixture containing a relatively high percentage of oil and of separating the mixture into first and second components which are discharged from said first and second outlet means respectively with said first component being relatively highly concentrated in oil and said second component being of relatively low concentration, the apparatus further including a secondary treatment section which includes one or more secondary cyclone separators (26) the or each separator including inlet means operatively connected to said second outlet means of said primary cyclone separator(s), said secondary cyclone separator(s) further including first and second outlet means and being of the type capable of handling mixtures containing a relatively low percentage of oil and of separating the mixture received from said second outlet means of said primary cyclone separator(s) into first and second components which are discharged from said first and second outlet means of said secondary cyclone separator(s) respectively, said first component containing substantially the remainder of the oil and said second component being substantially oil free.
