Therefore, it is very Important that the source of utilities and equipment be watched very closely. , 2. , . The purpose of emergency procedures is to prepare each operator with the knowledge of wbpt action can best be taken to keep the units running, or to try to maintain the unit in a safe condition when any of these utilities or pieces of equip ment are lost or when.the units have to be shut down. ' 3t We would also*5l16ik*7e*84 to keep the unit as near ready : for restart-up as possible* ; 4. Each Operator A is responsible to know the. duties of each man in his crew. He is also responsible to see that each man in his crew is thoroughly familiar with his duties. The Operator A is also to direct and co-ordinate the activities of his crew. 5. When confronted with an actual emergency,' quickly . analyze the situation and the type of emergency. . NOTE: Time is a factor in many emergencies, how ever, a moment spent in analyzing the situation may save time and avoid errors. Keep Calm!I 6.

PLANT: DEPARTMENT: OPERATION: PUGET SOUND CRD & HTU TOTAL POWER FAILURE DATE: DECEMBER 1971 Operator A: .1. If power failure is of short duration, it will "be only necessary to restart electric driven pumps that were in service. Also, 7C-K2 compressor will need to be restarted if it was lost on power outage. 2. When a power failure occurs gaind it Is not a momentary outage and pumps cannot be restarted shortly after wards: It is best to shut down both units and recycle gas through reactor systems. 3. Operator A will have to make the final decision on what procedure to follow, ' 4. Shut down the CRU and HTU reactor charge pumps (the HTU charge pump' should be down If on eleotrle) and block in the charge control valves. 5. Reduce firing in 6B-F1 beater to hold 90OF reaetor inlet temperatures. a. Reduce firing in 7C-F1 heater to hold 600F reactor inlet temperature. b. Cut fires out of 7C-F2 and 7C-F3 heaters and cut in safety steam. c. Shut down 6D-GM-23 pump and block off hot HSR Naphtha from the HTU to the CRU eharge drum. d. Isolate reaetor systems from each other and block in reactor systems to hold hydrogen gas heat to a minimum. Block vents off on the sour . seal traps, on the recycle gas compressors. Do not forget to close sample lines off to Ranarex. 6. Shut off all injection pumps and block in. 7. Shut down all.recovery pumps when not needed. a. Maintain oil circulation through the debutanizer charge coil of 6D-F1 heater while fires are in the heateri Will need to line up for this circulation.

Operator Bt When directed on what procedures to follow: NOTE: All heater temperature controls should be put on manual control when power failure occurs. 1. Reduce temperatures on the CRU reactors' Inlets' to 900F. _ . a. Reduce temperature on the HTU reactor inlet to 600F. b. Reduce charge rate to f design on the CRU. c. If on steam*, drive for the HTU charge pump;, reduce charge rate to \ design rate. d. When the charge is cut out of the CRU and the HTU reactor systems, close the charge control valves. 2. Lower the recycle gas compressors to 7000 RPM. a. Route. Fractionator tower gas to the flare when 7C-X2 compressor is lost on outage. 3.
