Three Screw Worm Compressor

Introduction

Screw compressors are positive displacement compressors that are widely used in the petrochemical industry to increase the pressure of gases or vapors. There are various types of screw compressors available in the market, and one such type is the Three Screw Worm Compressor. In this article, we will provide a complete and comprehensive guide on Three Screw Worm Compressor, including their types, applications in petrochemicals, advantages, disadvantages, and brands. Additionally, we will also discuss the role of Emaad in supplying this product in Iraq, Oman, Türkiye, United Arab Emirates, Dubai, and the Middle East.

What is a Three Screw Worm Compressor?

A Three Screw Worm Compressor is a positive displacement compressor that works on the principle of three intermeshing screw rotors. It consists of two parallel screw rotors that rotate inside a cylindrical stator. The rotors have helical threads that mesh with each other and with the stator’s worm gear teeth. As the rotors turn, the gas or vapor is trapped between the threads and the stator’s wall, and it is compressed as it moves towards the discharge port.

Types of Three Screw Worm Compressor

There are two types of Three Screw Worm Compressor – oil-injected and oil-free.

Oil-injected compressors use oil as a lubricant and coolant for the compression process. The oil also helps to seal the gaps between the rotors and stator, reducing leakage and improving efficiency. These compressors are commonly used in applications where high pressure and volume flows are required.

On the other hand, oil-free compressors do not use oil as a lubricant or coolant. Instead, they use a dry gas seal or a water seal to prevent leakage. These compressors are ideal for applications where oil contamination is not acceptable, such as in the food and pharmaceutical industries.

Applications of Three Screw Worm Compressor in Petrochemicals

Three Screw Worm Compressors are widely used in the petrochemical industry for various applications, such as:

1. Gas Gathering and Transmission: These compressors are used to compress natural gas and transport it through pipelines.

2. Petrochemical Processing: They are used to compress gases such as ethylene, propylene, and butadiene during the production of petrochemicals.

3. Refining: Three Screw Worm Compressors are used to compress gases such as hydrogen and nitrogen during the refining process.

4. Offshore Platforms: They are used in offshore platforms to compress natural gas and oil for transportation to onshore facilities.

Advantages of Three Screw Worm Compressor

1. High Efficiency: Three Screw Worm Compressors have high volumetric efficiency due to their unique design, resulting in lower energy consumption.

2. Wide Pressure Range: These compressors have a wide pressure range compared to other types of compressors.

3. Wide Flow Range: They have a wide flow range, which makes them suitable for various applications.

4. Low Noise Levels: Three Screw Worm Compressors produce low noise levels due to their smooth operation.

Disadvantages of Three Screw Worm Compressor

1. Higher Cost: These compressors are generally more expensive than other types of compressors.

2. Oil Contamination: Oil-injected compressors can cause oil contamination in the compressed gas or vapor, which may not be acceptable in some industries.
