“…The process of the adsorption dehydration package can be confirmed by classifying in detail equipment, input, output, and process function, respectively. According to the study of Park et al, the following equipment should be used for the operation of the adsorption dehydration package as represented in Figure . Inlet gas separator: After the injected gas is separated with the liquid, the liquid is disposed. Adsorber: Adsorption and desorption are performed to remove moisture from the gas. Regeneration gas heater: The regeneration gas that has passed through the separator is heated with the fuel gas. Regeneration gas cooler: The heated regeneration gas passing through the adsorber is cooled. Regeneration gas separator: The cooled regeneration gas is separated into gas and moisture, and then the moisture is disposed. Outlet gas filter: The impurities (dust and solid generated during process) in the dried gas are removed, and only the purely dried gas is passed. Ball valve: On/Off of the fluid flow. Sensor: Safety detection of measurement, leakage and malfunction for temperature, flow rate, and velocity of flow. …”

Probabilistic risk assessment techniques are the important tools which can considerably improve the safety performance of the studied system and reduce the risk to an acceptable level. Typically, decision‐making process is an important part of risk assessment methods that accordingly bring the ambiguity inside. Decision makers as experts commonly express their subjective opinions about the occurrence of the root events in order to obtain the probability of the undesired event. Subsequently, the critical root events are identified, and possible intervention is performed to reduce the probability of the critical events. However, the serious point is the viability of the obtained probabilities and priority ranking of the critical events. In this study, a heuristic optimization model of linear mathematical programming using triangular intuitionistic fuzzy number (TrIFN) is proposed to obtain the feasible, optimum, and reliable results compared with available methods. The Spearman correlation is performed to examine the reliability and behavior of the proposed model. In order to show the effectiveness of the proposed approach, it is applied on a real case study. The application of the model confirms its robustness to prioritize critical root events over the conventional one.
