Planificación del mantenimiento para tanques criogénicos de gases atmosféricos y dióxido de carbono para la empresa Hidrocobre Cía. Ltda.

Abstract

The maintenance planning of cryogenic tanks require develop theoretical concepts regarding cryogenic technology, production and maintenance of gas tanks. In the first part, the general concepts are indicate: Cryogenic technology, cryogenic distillation process, and the classification and description of cryogenic tanks. The current conditions of maintenance of cryogenic tanks, and management of available information is develops on the second part. The general inspection allow determining the physical and functional problems currently presented in the tanks. The third part establishes the methodology for maintenance planning; which it is consider on the principles established by the Total Productive Maintenance. The planning period is divide into four stages, which are knowledge of equipment, cleaning and inspection of equipment, fault analysis and standardization of maintenance. Additionally, a database is prepared with information gathered in the process of maintenance planning, which aims to develop a maintenance log. Finally, spare parts required for the implementation of corrective maintenance activities, and evaluation of maintenance costs and labor for corrective activities that require cryogenic tanks are established.
