This technical article focuses on an analysis and discussion of the design scheme for a specialized super filtration separator intended for screw compressors in production wells using thermal recovery and fire flooding techniques for heavy oil.
Fire-driven process technology has been primarily applied in recent years to scenarios such as thermal recovery of heavy oil and reactivation of old wells. That is, air is continuously injected into the injection well to ignite the oil layer underground. The hot water, flue gas, and steam generated by the combustion of the oil layer drive the crude oil from the injection wells to the production wells, enabling the combined recovery of crude oil, oil and gas, and flue gas. Fire flooding technology is, in fact, the combined use of gas injection lift, hot water flooding, and steam flooding techniques.
In the fire drive process, screw compressors are primarily used for pressurizing the raw gas in injection wells as well as for pressurizing the flue gas produced in production wells. In both cases, specialized super-filter separators are required to separate and protect the screw compressor, which is the core operating equipment. This technical article takes the design scheme of a specialized super filtration separator for inlet separation in screw compressors used to increase the pressure of flue gases produced by fire-driven production wells as an example for analysis and discussion.
The client has requested us to design and manufacture a specialized inlet super-filtering separator for two-stage screw compressors in the flue gas pressure boosting station of their fire suppression technology system. The operating condition data of the super filtration separator at the inlet of our primary compressor are as follows:
The composition of the flue gas collected at the pressure boosting station of this fire drive technology unit is as follows:
The owner puts forward the following requirements regarding the super filtration separator designed specifically for the two-stage screw compressor units in the flue gas pressurization station of the production wells equipped with the aforementioned fire-driven technology: 1. Use a super filtration separator to remove solid particles, dust, and liquid droplets contained in the gas. 2. Separation efficiency: For dust, 99% at 5 microns ； For droplets, 98%*5 microns. 3. Operating pressure drop: not exceeding 35 kPa.
Our party has selected stringent conditions based on the operating condition data provided by the owner, and utilized the NOVEL precise dynamics separation technology as well as the system platform for calculation and configuration design. The main technical specifications of the primary inlet filter separator for the screw compressors in the flue gas system of the aforementioned booster station are as follows: 1. Type of separator: Super filtration separator； 2. Separator model: G51F-16-232.1; 3. Column filter element set model: G51F-36/3 ； 4. Model of the precision vane separation internal component set: NOVEL G50CC-13; 5. Separation efficiency: 99.5%@5micron plus ； 6. Operating pressure drop: 1.288 psi (~8.9 kPa).
