FILTRATION SYSTEMS FOR CHEMICAL FLUIDS
A method of producing a filtration system for filtering a chemical fluid used in a hydrocarbon extraction well is provided. The method comprises providing a filter arrangement comprising an inlet end and an outlet end, connecting the inlet end to a first fluid flow passageway using a first hydraulically operated connector, and connecting the outlet end to a second fluid flow passageway using a second hydraulically operated connector.
1 . A method of producing a filtration system for filtering a chemical fluid used in a hydrocarbon extraction well, the method comprising:
providing a filter arrangement comprising an inlet end and an outlet end;
connecting the inlet end to a first fluid flow passageway using a first hydraulically operated connector; and
connecting the outlet end to a second fluid flow passageway using a second hydraulically operated connector.
2 . The method according to claim 1 , wherein the well is a subsea well, the filtration system being on a subsea structure.
3 . The method according to claim 2 , wherein the connectors are hydraulically operated by a remotely operated vehicle.
4 . The method according to claim 3 , wherein the remotely operated vehicle causes hydraulic fluid to be supplied to operate the connectors via respective lines from a connector portion with which the remotely operated vehicle engages.
5 . The method according to claim 4 , wherein the remotely operated vehicle engages the connector portion in a hot stab manner.
6 . The method according to claim 1 , wherein the filter arrangement further comprises an apex region, wherein the filter arrangement extends from the inlet end to the apex region and from the apex region to the outlet end.
7 . The method according to claim 3 , wherein the filter arrangement further comprises an apex region, wherein the filter arrangement extends from the inlet end to the apex region and from the apex region to the outlet end, and wherein the connector portion is at the apex region.
8 . The method according to claim 7 , wherein the remotely operated vehicle engages the connector portion in a hot stab manner.
9 . A method of producing a filtration system for filtering a chemical fluid used in a subsea hydrocarbon extraction well, the method comprising:
providing a filter arrangement; and
connecting opposite ends of the filter arrangement to respective fluid flow passageways by hydraulically operated connectors using a remotely operated vehicle which operates the connectors in a hot stab manner.
10 . The method according to claim 9 , wherein the remotely operated vehicle causes hydraulic fluid to be supplied to operate the connectors via respective lines from a connector portion with which the remotely operated vehicle engages.
11 . The method according to claim 9 , wherein the filter arrangement comprises an apex region, wherein the filter arrangement extends between the ends via the apex region.
12 . The method according to claim 10 , wherein the filter arrangement comprises an apex region, wherein the filter arrangement extends between the ends via an apex region, and wherein the connector portion is at the apex region.
13 . A filtration system for filtering a chemical fluid used in a hydrocarbon extraction well, the system comprising a filter arrangement comprising an inlet end and an outlet end, the inlet end being connected to a first fluid flow passageway by a first hydraulically operated connector, and the outlet end being connected to a second fluid flow passageway by a second hydraulically operated connector.
14 . The system according to claim 13 , wherein the filtration system is on a subsea structure of a subsea hydrocarbon extraction well.
15 . The system according to claim 13 , wherein the filtration arrangement further comprises an apex region, wherein the filter arrangement extends from the inlet end to the apex region and from the apex region to the outlet end.
16 . The filtration system according to claim 15 , wherein the filter arrangement further comprises a connector portion at the apex region, the connector being configured to engage an remotely operated vehicle for hydraulic operation of the connectors.
17 . A hydrocarbon extraction well comprising the filtration system according to claim 13 .
18 . A hydrocarbon extraction well comprising the filtration system according to claim 14 .
19 . A hydrocarbon extraction well comprising the filtration system according to claim 15 .
