摘要:
The present invention provides a method of generating steam for the recovery of hydrocarbon from a hydro-carbon producing system comprising: (i) generating supercritical steam from water; (ii) converting said supercritical steam to a subcritical steam; and (iii) injecting said subcritical steam into said system.

The invention relates to a lance for removing deposits adhering to the tube sheet of a steam generator, comprising a flexible strip which is introducing into intermediate tube areas of the steam generator, which has a cleaning head at the free end of the strip, and which comprises at least one water hose that is used to supply a flow of water to the cleaning head. In a use situation, the cleaning head comprises a working face which faces the tube sheet or deposits present thereon, an outlet opening which is fluidically connected to the water hose and opens into the working face, and a mechanical tool which acts on the deposits and removes material.

A syngas cooler apparatus includes an elongated generally cylindrical pressure vessel having an axial extremity that is a top end during normal operation of the cooler and an axial extremity that is a bottom end during normal operation of the cooler. A laterally extending support member extends within the pressure vessel proximate to the top end and front, back, and two side walls define at least one flow channel in the pressure vessel. The pressure vessel has an inlet and an outlet communicating with the flow channel. A pendant heat exchanger surface comprising a plurality of loops is disposed in the flow channel. Each of the loops is formed from tubing and the major portion of the entire axial extent of the tubing are rectilinear axial sections that are disposed with the axes thereof substantially in a vertical plan during normal operation. The pendant is disposed in the flow channel intermediate the inlet and the outlet and is supported solely from the laterally extending support member.

The present invention relates to a heating device for submersion within a tank of water to boil the water to produce steam, and for superheating the steam, comprising an outer sleeve; an inner sleeve partially disposed through the outer sleeve and having a proximal end, and a distal end in the form of an outlet port, the inner sleeve further defining a vapor chamber; a heating element disposed within the vapor chamber and in electrical communication with an external electrical power supply, the heating element adapted to produce heat in response to electrical energy from the power supply; a steam inlet tube extending outwardly from the inner tube and in fluid communication with the vapor chamber; and a one way valve disposed within the vapor chamber adjacent the outlet port, the valve adapted to selectively gate the flow of vapor from within the vapor chamber through the outlet port; wherein the heating device is configured to heat the water within the tank to a boil to produce steam, the steam inlet tube adapted to direct the steam into the vapor chamber wherein the steam is superheated through direct contact with the heating element producing vapor, the vapor generating sufficient pressure to open the valve and exit the heating device through the outlet port.
摘要:
An operating method for a separator for classifying, wherein superheated steam is supplied to the separator as separating gas, and wherein the temperature of the superheated steam as separating gas is selected to be so low that in particular no condensation of the superheated steam occurs in the separator. Further, a separator for classifying, wherein the separator includes a separating gas supply including a water infeed for generating superheated steam as separating gas, and wherein adjusting or regulating means for the temperature of the superheated steam are provided as separating gas and are designed in such a way that the temperature of the superheated steam as separating gas is adjusted to be so low that in particular no condensation of the superheated steam occurs in the separator.
