Question: What is the role of the reaction gas compressor in the (DMTO) olefin separation unit in the process? It raises the operating temperature for subsequent separation processes, thereby saving energy and materials required at low temperatures; compression causes water and heavy hydrocarbons in the reaction gas to condense, and these substances are removed in various separation stages, reducing the burden associated with drying and separation ； Acidic gases are removed after two-stage compression. Note: The answer will be announced automatically in two days!
Compress the gaseous components into liquid components
Learned :) Raising the operating temperature for subsequent separation helps save energy and materials required for low temperatures; applying pressure causes water and heavy hydrocarbons in the reaction gas to condense, and water and heavy hydrocarbons are removed at each separation stage, thereby reducing the burden associated with drying and separation； Acidic gases are removed after two-stage compression.
Answer: Raising the operating temperature in subsequent separation steps helps save energy and materials required for low temperatures; applying pressure causes water and heavy hydrocarbons in the reaction gas to condense, and these substances are removed through separation at various stages, thereby reducing the burden associated with drying and separation； Acidic gases are removed after two-stage compression.
Raising the operating temperature in subsequent separation steps helps save energy and materials required for low temperatures; pressurization causes water and heavy hydrocarbons in the reaction gas to condense, and water and heavy hydrocarbons are removed at various separation stages, thereby reducing the burden associated with drying and separation； Removal of acidic gases after two-stage compression
