How to recycle the solvent discharged from the vacuum system of the reaction kettle? Collection and condensation configuration of tail gas from the vacuum unit

In the vacuum distillation and vacuum desolventization processes of reaction vessels, if the solvent vapor is directly discharged after being extracted by the vacuum unit, it will not only cause material loss but also pollute the workshop. This article outlines the configuration ideas for collection, pre-condensation, and fractional recovery at the emission points of the vacuum system, providing a reference for fine chemical enterprises.

What causes the fuel dispenser to dispense fuel with the nozzle pulled up? A related investigation on the oil and gas recovery side

The issue of "gun-carrying and meter-running" can be divided into two categories: fixed value and continuous. The root causes often lie in the rubber hose of the fuel dispenser's foot valve and the breather valve. A continuous meter-running issue can also arise from a leaky connection between the oil and gas circuits on the recovery side. This article clarifies the mechanisms and troubleshooting methods for both categories.

How to determine the wind speed of the branch pipe for workshop exhaust gas collection? What are the design diameters of the branch and main pipes

The wind speed of branch pipes is determined based on sedimentation risk in different sections, while the main pipe is designed according to the velocity reduction of converging airflow. The wind speed inside the pipes must be higher than the lower limit of dust accumulation. This article clarifies the criteria for value selection, pipe fitting design, and key points for commissioning and acceptance.
