E. G. Leser March, 1980 Chambers Works Bldg. 770 1-1-1 DYES AREA EAST SPRAY DRYER NO. 1 Principle of Process A slurry or solution of product is pumped to an atomizing nozzle. A stream of compressed air is impinged upon the liquid stream causing it to atomize. The droplets of material thus formed come in contact with a large volume of hot air and the water is flashed off. The dry product is separated from the air stream. The product is discharged to containers and the air stream is discharged to the atmosphere. Reactions There are no chemical reactions done during the drying step. N32957 DUP050467516 E. G.

Leser March, 1980 OPERATING INSTRUCTIONS SUBJECT: DYES AREA EAST SPRAY DRYER NO. 1 OPERATION: Chambers Works Bldg. 770 III-3 Loading Feed Tanks 1. Check T-36 to be sure valves under tank are closed and tank is clean. When charging T-36, use funnel. Supervisor-Production must check cleanliness of tank. When direct loading T-54 or T-86, use screen. 2. Measure a small amount of water into tank, T-36 (Approximately 250-300 lb.). Turn on agitation. Do not use any water if milled slurry is to be used. If material to be loaded has settled, bucket off the liquid into the tank, using this liquid in place of the water. 3. Load by shoveling and/or dumping material as called for on the lineup card. Record all amounts of material loaded. Agitation can be helped if the tank is hooked up to recirculate and pump is started. WEAR GLOVES IN HANDLING. 4. Agitate and recirculate until a smooth slurry is obtained. Sample as called for. Obtain sample from recirculation line. Adjust pH as called for on line-up card. See sample list and line up card for samples to be taken. 5. Pump charge from make up tank (T-36) to feed tank (T-54 or T-86) through the manhole screen (agitation must be on in feed tanks). Omit this step if feed tank is loaded directly, as in the case of milled products. 6. After charge is in feed tank, rinse out make up tank with no more than 250 lb. of water and pump this to the feed tank. 7. After feed tank is loaded, dry dip tank, record on log sheet and sample to GAL for Gross Solids. Record dry dip and gross solids?on line-up card.
