Petrochemical Industry:

In the petrochemical industry, Atlas (Yantai) vacuum pumps can handle various variables such as intake airflow, explosive gas mixtures, dirty friction gas mixtures, and unpredictable airflow. They offer a unique comprehensive supply range, including vacuum pumps, compressors, and composite systems suitable for various applications in the petrochemical industry. Vacuum pump applications are versatile, and based on user requirements, integrated systems with multiple functionalities can be provided along with proprietary technical consultation. 

Gas Recovery

In the oil and natural gas industry, gas recovery is the process of recovering tank hydrocarbon gases before they are released into the atmosphere, whether in upstream production or downstream refining. Gas recovery involves removing gas from the tank by vacuuming and compressing it. Liquid ring pumps can be used to recover and liquefy the gas, allowing for the reuse of ethane gas.
Enhanced Oil Recovery 

Enhanced Oil Recovery (EOR) is an upstream process that involves eliminating vacuum from oil wells to alleviate well pressure, allowing oil to flow more freely and increasing oil production. It also includes associated gas recovery, which involves recovering gas that accompanies oil as a byproduct or at the wellhead. Recovery typically occurs at the wellhead using oil/gas separators.
Gas Collection

Gas Collection is an upstream process that involves evacuating and compressing gas from several oil wells into a manifold or storage tank. This process is typically carried out by vacuum pumps or low-pressure compressors, which press the gas into high-pressure pipeline compressors, often reciprocating compressors, and then into gas processing equipment for treatment.
Crude Oil Stabilization
Crude Oil Stabilization involves using liquid ring pumps or compressors to remove dissolved gases and stabilize the actual vapor pressure of the crude oil. This process is achieved by adjusting the vacuum level in the crude oil tank and reducing the compression at the exhaust port, depending on the ambient temperature changes. This helps enhance the safety of the crude oil tank.

Crude Oil Vacuum Distillation

Crude Oil Vacuum Distillation involves processing fuel through atmospheric or vacuum distillation to produce gasoline and other hydrocarbon fuels. This method includes the application of vacuum equipment to crude oil distillation towers. Through the combined action of heat and vacuum pressure, crude oil is separated into different components based on their boiling points. The objective is to extract lighter components such as gasoline. Vacuum distillation offers higher efficiency compared to atmospheric distillation.

Steam Recovery / Gas Boosting

This differs from gas recovery as steam recovery is relatively fixed and immutable. Typical applications include collecting tank exhausts. Tight control of vacuum levels is maintained to safeguard the tanks. Typically, exhaust pressures are relatively low. Gas often returns to the processing system or undergoes liquefaction before returning to the tank.

Filtration / Wax Removal

Filtration or wax removal refers to the collection of wax components in hydrocarbon oil production. Removing wax components from oil can improve its quality and applicability. Liquid ring pumps continuously eliminate vacuum levels that may contain freezing MIBK nitrogen gas from disc or drum filters. If higher vacuum levels are required, mechanical blowers and liquid ring pumps will be installed to work in conjunction.

Tail Gas Recovery

In flare gas / tail gas recovery systems, liquid ring compressors are an ideal choice. One of the main reasons is that gas compression is essentially isothermal, with temperatures typically ranging from 30 to 50 degrees Celsius. This helps avoid issues such as gas polymerization inside the compressor due to high temperatures, which may occur when using other types of compressors.

Polyester Production

In polyester production, the required vacuum inside the reaction tower can be achieved using a composite vacuum system composed of steam ejectors and liquid ring pumps. Unlike other applications, ethylene glycol (EG) can be directly used as the working fluid for the liquid ring pump in order to ensure the safe and reliable operation of the entire vacuum system.
PVC Production

In the production process of polyvinyl chloride (PVC), the residual vinyl chloride monomer (VCM) in the reaction is first extracted by liquid ring vacuum pumps and then transferred into storage tanks. Subsequently, it undergoes compression by liquid ring compressor units to approximately 0.7 MPa absolute pressure, where it is stored in liquid form in VCM recovery tanks for further reactions.

Chlorine Gas Packaging

In the chlorine packaging process at chlor-alkali plants, the use of liquid ring compressors with high outlet pressure can significantly reduce costs and mitigate environmental pollution risks.
