After the reactor has been rinsed following the dump cycle, it is

ready to be chem-washed. The chem-wash cycle is necessary to remove

any polymer build-up from the reactor condensor, walls, baffles and

If allowed to remain in the reactor, they continue to grow with each m
successive charge. Build-ups will contribute to high gel, low quality

MANUFACTURING PROCEDURE
Department: Large Reactors
ProcessTitle: Large Reactor Operations
Procedure Section Title.: Full & Partial Swirl Of Reactor
Issue Number: _JLI
Issue Date: A/ll/75
Reason For Issue:...Original Originated By: Gilbert A..Jttoxsan
To assist in the production of quality resin, particularly *low-gel,
*
It has been found that by filling the reactor with water and agitating,
*
the gel count is markedly lower.
FULL SWIRL:
In this swirl, the reactor is almost completely filled with water
The Operator:
1. Has Reactor Operator open man-head
.2 Open main dump valve.
3. Open water charge valve.
4
4. Start both A & B hot water charge pumps.
*
5. Add 1,800 counts of water to reactor (18,000 gallons)
6 Cut off pumps and close valves.
7* Agitate for ten minutes.
%
8#. Open swirl or sewer valve and dump.
