| 摘要 |
A submerged combustion vaporizer which produces a mixture of high pressure saturated steam and combustion flue gas or alternatively superheated steam and combustion flue gas for injection and recovery of hydrocarbons from a reservoir. Steam is produced by direct contact between raw untreated water and high-pressure high-temperature combustion flue gases introduced into a pressurized water bath. For low pressure hydrocarbon recovery processes where the temperature of saturated steam is insufficient for hydrocarbon viscosity reduction, the vaporizer is configured to produce a superheated steam and flue gas mixture of sufficiently high temperature to achieve a lower hydrocarbon viscosity. |
