Propylene compressor

1. Product Overview: Propylene compressor is a rotary or reciprocating positive displacement compressor specially used for conveying and compressing propylene (c₃h₆) gas. Propylene is an important basic raw material and refrigerant (r-1270) in the petrochemical field, and its compression equipment must fully consider the flammable and explosive properties (a1 gas) and specific thermodynamic properties of the medium when designing and operating. This kind of compressor usually belongs to the key dynamic equipment in the process flow, which is used to boost the pressure of propylene to meet the needs of different process links such as polymerization, separation, liquefaction, circulation or refrigeration. According to the pressure and flow requirements, the common types are reciprocating, screw and centrifugal.

2, characteristic performance:

The security requirements are extremely high:

Leak-proof design: adopt high-quality dry gas seal, double-ended mechanical seal or labyrinth seal, and cooperate with reliable sealing gas system to ensure that propylene is not leaked.

Explosion-proof electricity: All motors, instruments and control elements must meet the highest explosion-proof standards (such as ex d iic t4).

Adapting to the particularity of media:

Anti-polymerization design: self-polymerization of propylene may occur under certain conditions, and compressor design (such as flow passage and cooling) should consider inhibiting polymer generation or facilitating cleaning.

Consider phase change: During the compression process, the temperature and pressure should be accurately controlled to prevent propylene from liquefying (for gas phase compression) or "liquid hammer".

High purity requirements: compressors used in polymer or food-grade applications need to ensure internal cleanliness and grease pollution control.

3. Scope of application: Propylene compressor is a kind of precision industrial equipment specially designed for high-risk media. Its core is "safety, stability and high efficiency". It is widely used in key links from basic raw material production to high-end polymer manufacturing to large-scale low-temperature refrigeration. It is an indispensable and important equipment in modern petrochemical industry.
