The invention relates to a separating device for tubular flow-through devices () which serve for the extraction of liquids or gases from wells drilled in rock or deep wells, the separating device being suitable for the removal of sand and rock particles and comprising

Separating device for tubular flow-through devices

A separating device for removing sand and rock particles, and is an integral component of extraction equipment for extraction of liquids or gases from deep wells, having at least one ceramic filter module comprising: an annular stack of annular discs, the upper side of which has at least three elevations uniformly distributed over the circumference of the discs, the discs are stacked such that a separating gap for the removal of sand and rock particles is present between the individual discs, a coupling-on element at the upper end and a coupling-on element at the lower end of the annular stack, a clamping device bracing the annular stack, an outer cage, a coupling element at the upper end and a coupling element at the lower end of the filter module connecting the filter module to further components of the extraction equipment.

Wear-resistant separating device for removing sand and rock particles

Pipe lines for conducting natural gas become contaminated, over a period of time, by an accumulation of mercury, which occurs in minute amounts in natural gas. If used pipe is scrapped, for example by melting, mercury vapor escaping to the atmosphere poses a health hazard. To remove mercury, sections of pipe are closed at both ends by plugs having nipples for connection to a closed circuit and inert gas line connected with a pump for evacuating the line and with a source of inert gas, for example nitrogen. The closed circuit inert gas line contains a blower for circulating the inert gas repeatedly through the pipe sections and a condenser for condensing mercury vapor. The closed circuit further includes a heat exchanger for removing heat upstream of the condenser, a coordinated heat exchanger for restoring heat removed and an additional heater. The pipe sections are heated externally by an oven or internally by heated inert gas.
