Analysis of the causes of the occurrence of an irregular process of obtaining polyamide 6

Abstract

An analysis of the possible failures of the process of obtaining polyamide 6 by polymerization of caprolactam in VK – pipes, by using the FTA method, is performed in this paper. The main factors contributing to the poor progress of process was identified by using deductive analysis and by forming a fault tree for the adopted top event. Considering the possibility of their control, can be reduced the expected losses, and achieved in that way better production of sintered polyamide 6th. The procedure of forming the minimal cut sets for the concrete example is explained. By analysis of the common cause ranking of secondary causes of basic fault tree events, according to their influence on the top event occurrences, was performed, and the possibility of eliminating the causes of failure was considered. In conclusion, the paper presents possible applications of the achieved results.
