Questions about product compression
Thread Content
The MTO product gas is compressed by a compressor, resulting in high pressure; the relative volatility of its various components is low, making separation difficult. Low pressure and low operating temperatures also hinder the separation of the products. And the compression process is set to 4 stages of compression – what is the basis for this? Inter-stage coolers are added to prevent excessive temperatures that could cause the olefins to polymerize; a temperature of less than 90°C is required. So at what temperature does polymerization of olefins occur? I’m learning *separation for the first time; I would appreciate your guidance.
Compression is done to create a high-pressure condition; the reason for needing high pressure depends on the conditions upstream and downstream. It is divided into four sections because compressing it in one step does not yield the desired result; thus, four steps are needed. You lack too much basic knowledge, which makes it difficult to understand the issues related to the system
