In the Natural Gas processing operations conducted at the Central Processing Plant (CPP) Donggi and Matindok, PT Pertamina EP - Donggi Matindok Field, impurities are removed through an absorption process utilizing amino solvent-based chemicals. This process takes place at the Acid Gas Removal Unit (AGRU). However, during the Carbon Dioxide Absorption Process at CPP Donggi and Matindok, Off-Spec conditions have been observed in comparison to gas sales products. This discrepancy is attributed to the presence of Carbon Dioxide impurities exceeding the acceptance limit, stemming from suboptimal performance of the AGRU unit. The inefficiency arises due to the solvent composition's inability to consistently carry out the impurity removal process from the feed gas, which exhibits a dynamic composition.

To address this challenge, a method is required to analyze the real-time state of the processes within the AGRU unit. This analysis can be achieved through trials or simulations replicating the ongoing processes in the AGRU unit. The author proposes the implementation of the Minisorb tool as a solution for conducting analyses under actual and real-time conditions in the AGRU units at CPP Donggi and Matindok.

Operating on the principle of replicating real-time conditions within the AGRU unit while in contact with the actual Feed Gas and Current Formulated Solvent, the Minisorb tool allows for real-time process replication. This approach enables the precise application of production parameters without the need for trial processes, thereby minimizing high risks associated with such trials.
