96- The inlet gas-liquid separator of the oil and gas booster compressor uses a NOVEL vane separator for the KAM oil and gas project

A domestic oil and gas company is also involved in the EPC of some parts of this project. The KAM project, also known as the Kyzylorda project, is owned by a joint venture between the British company AMLON and a local Kazakhstani company named KUAT; it benefits from significant tax incentives in Kazakhstan, which has motivated high enthusiasm on the part of both the project owners and the construction parties.

The process flow of the oil and gas treatment unit in this project is similar to that of certain domestic oil and gas fields, such as the Yuedong Oil Field and the gas fields in the southwestern region; both use the STATION SEPARATORS SKID design.

The process of its oil and gas treatment unit is briefly described as follows: The gas phase, after being processed by the three-phase production separator, is sent in part to the heating and throttling separation skid. There, it passes through a high-efficiency vane-type gas-liquid separator to remove any liquid droplets or mist present in the gas, after which it enters the pressure-boosting compressor to have its pressure increased. The gas with increased pressure is then used as fuel for the heating furnace, providing heat energy for the heating of the skid. The other portion of the gas stream, after having the liquid droplets and mist carried within it removed using a vane-type high-efficiency gas-liquid separator, enters a booster compressor for pressurization; the resulting product gas is then sent to the pipeline network and delivered to downstream user units. The client requires that the gas-liquid separation device before the compressor use a vaned high-efficiency gas-liquid separator.

Let’s first take a look at the technical operating parameters of the liquid-liquid separator at the inlet of the booster compressor in the heating, throttling, and separation skid: 1. Operating temperature: 15°C to 40°C, with values tending towards 15°C in winter and 40°C in summer℃； 2. Operating pressure: 2.5~4.5 BarG ； 3. Gas flow rate: 50,000~60,000 Nm^3/d; 4. Process inlet and outlet pipelines: 6"*300# ； 5. Gas flow composition: (mol%) N2, 1.06 ； CO2, 0.03; C1, 89.99; C2, 5.46; C3, 1.09; IC4, 0.45; NC4, 0.92; IC5, 0.31; NC5, 0.29; C6, 0.29; C7, 0.08; C8, 0.03.

Operating temperature: 15°C to 40°C, with values tending towards 15°C in winter and 40°C in summer℃； 2. Operating pressure: 2.5~4.5 BarG ； 3. Gas flow rate: 1,100,000 Nm^3/d; 4. Process inlet and outlet pipelines: 14"*300# ； 5. Gas flow composition: (mol%) N2, 1.06 ； CO2, 0.03; C1, 89.99; C2, 5.46; C3, 1.09; IC4, 0.45; NC4, 0.92; IC5, 0.31; NC5, 0.29; C6, 0.29; C7, 0.08; C8, 0.03.

Owner’s requirements: 1. 3N-level removal of C4, C4+, and water droplets/mist from the inlet airflow of the compressor； 2. The operating pressure drop of the separator shall not exceed 20 kPa ； 3. Since oil and gas contain paraffin and sediment, the internal components must be resistant to clogging, removable and recyclable, and suitable for efficient, continuous, and stable operation over very long periods of time; it is not acceptable for these components to require spare parts for operation ； 4. Design must be carried out in accordance with ASME standards.

Based on the technical parameters and requirements provided by the client, we used the NOVEL dynamics gas-liquid separation precise calculation and design system platform to carry out accurate quantitative design for the heating, throttling, separation units, lift compressors, and inlet gas-liquid separators. The results are as follows: 1. Separator type: NOVEL G50 vertical vaned separator； 2. Inner component type: G50-type vaned separation patented technology inner components and patented configuration technology ； 3. Equipment dimensions: ID600*SM/SM850 ； 4. Operating pressure drop: 0.63 kPa ； 5. Quantitative separation efficiency: 99.9% in separating and removing liquid droplets and bubbles with a size of 6.37 microns or larger.

Is the flow rate a bit high when using 14\" pipes for 1100000 Nm3/d?
