Abstract

The treating stage in a Catalytic Reforming Unit (CRU) is a critical process to ensure the longevity and efficiency of the reforming catalyst. However, anomalies like sudden and significant increases in reactor pressure drop, as observed in this case, can disrupt operations and reduce the unit's overall performance. It is crucial to identify the root cause of the observed pressure drop anomaly using the Fault Tree Analysis (FTA) method to systematically investigate the issue from multiple perspectives, enabling the identification of both minor and significant contributing factors. The FTA results indicate that external debris introduced during a recent catalyst changeover (COC) activity is the most likely cause. This allegation is supported by the analysis of equipment operation data and feed condition records, which did not reveal any significant changes. Given the absence of internal factors, the external influence of the COC activity emerges as the primary explanation for the pressure drop increase. To prevent similar occurrences in the future, it is crucial to implement rigorous cleaning and inspection procedures during turn-around (TA) activities to minimize the risk of debris entering the system. Monitoring reactor pressure drop and feed quality can also help detect and address potential issues early on. By taking proactive measures, the reliability and efficiency of the treating stage can be maintained, ultimately improving the overall performance of the CRU.

Abstract

The use of a Thermal Oxidizer (TOX) aims to treat industrial waste gases by oxidizing harmful gases, such as sulphur dioxide (SO₂) and hydrogen sulphide (H₂S), at high temperatures. This study aims to evaluate the TOX operating conditions and analyze its efficiency in reducing harmful emissions released to the environment. Operating data is based on temperature, pressure, gas flow rate, and SO₂ concentration measurements from the Thermal Oxidizer (TOX). The measurement results show that the SO₂ emissions meet the government's standard setting below the maximum limit of 2,600 mg/Nm³. However, the actual TOX performance efficiency of 45.61% decreased compared to the initial design efficiency of 63.27%. This decrease was due to several factors, including reducing the hot oil flow rate and leakage in the chamber.

Abstract

One of the operating units of PT. Y, which functions to separate fractions based on differences in boiling routes. Serves to separate fractions based on differences in boiling routes and under vacuum pressure conditions in the High Vacuum Unit (HVU). This is because the feed in this operation contains long residues that consist of long hydrocarbon chain components or have a high boiling point. One of the leading equipment used in this unit is a furnace. The efficiency of furnaces in the High Vacuum Unit (HVU) is critical because furnace efficiency is paramount as it directly influences operational costs and energy consumption in the separation process. The study addresses the problem of optimizing furnace efficiency, which is crucial for reducing fuel usage, particularly fuel gas, thereby enhancing the overall economic viability of the operation. The research employs a methodology that analyzes heat absorbed and heat loss within the furnace system. By measuring these parameters, the study identifies areas for improvement in thermal efficiency. Optimization involves adjusting fuel inputs and operational settings to minimize waste while maintaining effective heating capabilities. The optimization results show a significant decrease in fuel gas usage by 2,14%, compared to the average consumption level recorded in July 2024. In addition, fuel oil usage was optimized to 3 tons per day (T/D). These adjustments improved the furnace's efficiency and contributed to a more sustainable operation. The findings of this optimization study have broader implications for energy efficiency and cost savings in operations. By improving furnace performance, PT. Y can achieve lower operational costs and reduce its environmental footprint through decreased fuel consumption. This aligns with the industry trend towards sustainability and efficient resource management, benefiting the company and society.
