An apparatus and corresponding method of use extracts, cools, and transports effluents from subterranean, sub-sea oil formations to distant shore based processing facilities. The effluents, mostly crude oil, are conveyed rapidly to a cold flow generator near the oil wellhead on the sea bottom using the cold seawater to chill the effluents to a dispersed mixture including generated solids. The mixture is transported close to sea bottom temperatures, slowly, with small pressure drops, in low-cost submerged bare pipes over long distances to on or near shore processing facilities that can produce useful hydrocarbon products more cost effectively than at sea processing facilities. The apparatus eliminates or minimizes the need for heated or insulated pipe, the need for large floating processing structures, the need for sub-sea processing equipment, and/or the need for chemical additions to production flow.

Materials including suspended particles are brought together and then separated into two streams one of which only contains the particles, the output streams having different composition from inlet streams. Separation is effected in filtration modules which include a moving runner with wall conditioning elements which dislodge accumulated particles from porous walls of filters.

A processing wall is made part of a boundary of a continuous reentrant lumen, and wall conditioning runners circulate around this lumen to dislodge accumulated material from the processing wall and thereby continually restore the wall to the condition required for efficient operation.

A filter medium is provide in a tubular structure configured in the form of a closed loop. Filter maintenance structures mounted on a continuous string lying within the lumen of the tubular structure are continually driven over the surface of a filter medium to maintain an optimum condition of the filter surface. This string with attached filter maintenance structures is driven around the loop of the tubular structure by hydraulic forces generated by the fluid introduced into the apparatus for filtering.

A flexible rod-and sleeve assembly with rod and surrounding sleeve affixed to each other at their bottom ends is maintained by a spring to put the sleeve in tension. The assembly is inserted into a cavity such as a monitoring well so as to extend below the lowest level which the water table may assume. The sleeve is made of a material which is attacked by petroleum products but not by water, and when a layer of petroleum liquid such as gasoline collects on the surface of the water in contact with some region of the sleeve, the sleeve material loses its strength and ruptures. This results in an upward movement of the sleeve, which is used to actuate alarm and signaling mechanisms.
