Study Of The Effect Of Hydrogen Sulfide Levels Found In Petroleum In The Processing At PT Pertamina EP Region Sumatra Field Pangkalan Milk

Introduction

The processing of petroleum at PT Pertamina EP Region Sumatera Field Pangkalan Susu is a complex task that requires careful consideration of various factors, including the hydrogen sulfide (H₂S) content in crude oil. H₂S is a colorless gas that smells foul like rotten eggs and is highly toxic, posing a significant threat to human health and the environment. In this study, we aim to investigate the effect of H₂S levels in petroleum on the processing at PT Pertamina EP Region Sumatera Field Pangkalan Susu and explore the challenges and solutions associated with managing H₂S content.

The Importance of Hydrogen Sulfide Analysis

Hydrogen sulfide analysis is a crucial step in the processing of petroleum at PT Pertamina EP Region Sumatera Field Pangkalan Susu. The percentage of H₂S in crude oil is analyzed using titration, and the maximum value of H₂S in crude oil is set at 0.1%. This is because high levels of H₂S can cause corrosion in storage tanks and process equipment, pollute the environment, and reduce the quality of the final product. Understanding the density of crude oil is also essential, as it is influenced by various factors, including H₂S, nitrogen, oxygen, metals, water, and chloride salts.

Challenges Associated with High H₂S Content

High H₂S content in crude oil can cause several challenges in the processing, including:

Corrosion

H₂S can cause corrosion in the process of crude oil processing, leading to damage and high repair costs. Corrosion can occur in storage tanks, pipelines, and process equipment, resulting in significant financial losses.

Pollution

H₂S is a toxic gas that can pollute the air and water, endangering human health and the environment. High levels of H₂S can cause eye, nose, and throat irritation, fainting, damage to the respiratory system, and even death.

Separation

H₂S needs to be separated from crude oil before further processing, as this gas can interfere with the processing and reduce the quality of the final product.

Solutions to Overcome H₂S Content

Several solutions can be employed to overcome the challenges associated with high H₂S content in crude oil, including:

The Use of Corrosion Inhibitors

Corrosion inhibitors can reduce the level of corrosion caused by H₂S on crude oil process equipment, minimizing damage and repair costs.

Sweetening Process

The sweetening process aims to reduce the content of H₂S in crude oil using various methods, such as absorption, oxidation, or hydrogenation.

Acid Gas Processing

Acid gas containing H₂S can be processed to produce sulfur or re-injected into an oil well to increase oil production.
