Response to PHEF PHR (Precipitate Hydrolysis Experimental Facility Process Hazards Review) Recommendations.

摘要

The PHEF Process Hazards Review (PHR) Committee recommended that startup of the Precipitate Hydrolysis Experimental Facility (PHEF) with the four runs originally planned to process a low nitrite (< 0.03 M) precipitate feed proceed as planned. The PHR committee outlined seven action items designed to improve the safety and reliability of the PHEF with respect to process hazards. This memorandum addresses each action item from the PHR Startup Review and outlines the response actions taken or explains why corrective action is judged unnecessary in a particular circumstance. Based on the PHEF Safety Evaluation, the PHEF PHR, and the responses herein, we conclude the PHEF can be safely started as planned. The PHEF will not operate with the Nitrite-Destruction Precipitate Hydrolysis until the action items from the final PHR report are addressed. 3 refs. (ERA citation 14:003356)
