At the New Talara Refinery, the Flexicoking process is part of the “deep conversion” refining scheme due to its more complex configuration (Nelson index > 12), which is characterized by processing heavier crudes and valuing waste. Unlike the delayed coking process, the Flexicoking technology has few references and fewer operating units, which could present some operational problems. The energy exchange technologies in the Flexicoking unit are, in some cases, non-conventional technologies that need to be studied, as in the case of the steam generator that operates in condenser mode in part of the unit startup, or as the heat exchanger in spiral for highly viscous and corrosive products (slurry), or as the recovery exchanger and plate exchanger in the regeneration of flexsorb, among others, therefore, the objective of this thesis is to determine the influence, based on the operational criticality, of these energy exchange technologies to perform an optimal and safe operation of the Flexicoking unit. It has been considered to establish the operational criticality (OC) of a piece of equipment based on the criticality by variables (CV) and the criticality by failures (CF). The risk-based inspection (IBR) methodology was used to evaluate the operational variables based on a variable criticality matrix, where the highest valuation for a piece of equipment will determine its criticality per variable (CV). The direct influence of service/power failures (11 failures) on the equipment was analyzed and evaluated, the greater the failure, the greater the criticality, promoting the level of criticality per failure (CF) for each equipment. As a result, the following were obtained: The E-312 recuperator and the E-311 reboiler are critical because they provide regenerative heat, they also recover and regenerate the flexsorb respectively (high cost for being a patented amine). The high-pressure steam generator E-102 and the high-pressure boiler water preheater E-103 are critical due to their high influence on the steam generation section and on the cooling of the flexigas. The COS E-306 A/B preheater is a critical piece of equipment to take care of the COS converter reactor catalyst despite having other equipment on standby. The E-101 steam generator is moderately critical even though it influences the unit's startup with two operating modes. The rest of the steam generators and heat exchangers are moderately critical due to the degree of similarity of influence.
