摘要： A method of inhibiting the formation of fouling deposits occurring in spent caustic wash systems used for ethylene dichloride (EDC) manufacturing processes. Fouling occurs in these systems when they are in contact with EDC processing streams contaminated with oxygen-containing compounds, such as aldehydes. These deposits are formed in EDC processing streams contaminated with oxygen-containing compounds while in contact with a caustic solution having a pH>7. The invention comprises adding an effective deposit-inhibiting amount of a non-enolizable carbonyl compound to the caustic solution. Preferred non-enolizable carbonyl compounds are formaldehyde, glyoxal, benzaldehyde, p-anisaldehyde, formic acid, glyoxalic acid and paraformaldehyde.

摘要： Generally, the invention provides a fouling probe apparatus. The fouling probe including a heat transfer conduit having a first portion formed as a loop which is removably attached to a second portion which extends linearly. A hollow housing encases the apparatus. The housing has an open forward portion and an open rear portion. The open forward portion is attachable to an oil quench tower about an opening in the quench tower and the open rear portion is adapted to be securely attached to the linearly extending second portion of the heat transfer conduit. A fouling grid is attached to the first portion of the heat transfer conduit. The fouling grid is super-heated to accelerate fouling.

摘要： In a method for reducing the fouling of a compressor of a vinyl acetate production unit having a light ends stream feed, a hindered phenol is added to the compressor feed. The method retards the loss of compressor efficiency with run time and increases the run time before clean-out is required. The hindered phenol is added in a dosage amount effective for reducing the fouling of the compressor.
