corrugated plate interceptors
4M Process can supply two designs of Corrugated Plate Interceptors (CPIs). One is an atmospheric design which is box type and the other a pressurized design which is fabricated in accordance with ASME VIII, Division1 classification code.
CPI separators are ideal for the separation, removal, and recovery of oil and suspended solids from process water or wastewater streams. They provide an economical way to remove the bulk of the oil and contaminants and in some applications are most often the only separation equipment needed.
CPIs use a coalescer/distributor to make small oil droplets into more easily separable, large droplets and to distribute the flow evenly over the width and height of the separator. The plates are sloped to a 45 or 60 degree angle to minimize the possibility of sludge fouling.
Corrugated Plate Separators offer advantages over other gravity separators such as API pits and settling tanks are:
- CPIs are compact resulting in lower capital and installation costs.
- Plate separators can remove smaller size droplets, resulting in better separation efficiency.
- Plate separators are fully enclosed and can be gas blanketed, eliminating emission of volatile organic compounds (VOCs) and reducing fire hazards.
