Abstract

Corrosion on the internal equipment of the Net Gas Wash Column is the thinning of the material which, if prevention or control is not carried out, will cause damage or leaks to the equipment. Internal corrosion of equipment such as Net gas wash columns is a common problem in industries that use chemical processes or gas processing. Corrosion occurs when metal materials react with the surrounding environment, such as gases involved in the process, moisture, or other chemicals. Several factors that can cause internal corrosion of equipment such as the Net Gas Wash Column include environmental conditions, material properties, temperature and pressure and the presence of water or humidity. This research aims to determine the corrosion conditions that occur, the impact of corrosion rate, thickness thinning, and the relationship between corrosion rate and remaining lifetime. This research uses a non-destructive testing method, namely the Ultrasonic Test. The results of the analysis and calculations were obtained for the corrosion rate that occurred on the Net Gas Wash Column tool, namely shell 0.11 mm/year and head 0.3 mm/year which was caused by temperature and working flow rate. The direct impact of corrosion is equipment damage and the indirect impact is the costs incurred to replace the equipment. The remaining lifetime for the shell and head is 69 years and 40 years. When the remaining lifetime decreases, the depletion caused by the H2S compound and the corrosion rate will increase immediately. From the results of this research, the relationship between the causes, impacts and corrosion rates on the remaining lifetime of the Net Gas Wash Column equipment can be identified and analyzed.

Abstract

ABSTRACTThe success of drilling activities is greatly influenced by drilling mud. Coal contamination in drilling mud will damage the mud’s performance in carrying out it function during drilling operations. Coal contamination in drilling mud can affect a number of physical properties of drilling mud such as density, rheology properties, and filtration loss. To maintain the performance of the drilling mud due to coal contamination in drilling activities, it is necessary to add Polyanionic Cellulose - Refined (PAC-R). Based on the reasearch results, the effect of coal contamination 1%, 2%, 3%, and 4% (sample B) can change the physical properties of drilling mud such as reducing the rheology value of drillinh mud and increasing the filtration loss value. Therefore, the addition of PAR-R additives is needed to control the physical properties of the drilling mud. From the results, the addition of PAC-R additives of 0,3% and 0,5% (samples C2 and C3) can provide changes to the rheology value of drilling mud according to the drilling mud specifications. This is because the PAC-R additive functions to reduce filtration in drilling mud and as a viscous in the mud to increase the rheology value of the mud.Keywords: Mud Drilling, Coal Contamination, Rheology Properties, PAC-R. ABSTRAKKeberhasilan kegiatan pemboran sangat dipengarui oleh lumpur pemboran. Kontaminasi batubara dalam lumpur pemboran akan merusak kinerja lumpur dalam menjalankan fungsinya selama operasi pengeboran. Kontaminasi batubara dalam lumpur pemboran dapat mempengaruhi sejumlah sifat fisik lumpur pemboran seperti densitas, sifat rheologi, dan filtration loss. Untuk menjaga kinerja lumpur pemboran tersebut akibat kontaminasi batubara dalam kegiatan pemboran, maka perlu penambahanan Polyanionic Cellulose - Refined (PAC-R). Berdasarkan hasil penelitian, pengaruh dari kontaminasi batubara 1%, 2%, 3%, dan 4% (sampel B) dapat merubah sifat fisik lumpur pemboran seperti menurunkan nilai rheology lumpur pemboran dan menaikan nilai filtration loss. Oleh karena itu dibutuhkan penambahan zat additive PAC-R untuk mengontrol sifat fisik lumpur pemboran tersebut. Dari hasil pengujian, penambahan zat additive PAC-R sebesar 0,3% dan 0,5% (sampel C2 dan C3) dapat memberikan perubahan terhadap nilai rheology lumpur pemboran sesuai dengan spesifikasi lumpur pemboran. Hal ini dikarenakan zat additive PAC-R berfungsi untuk mengurangi filtrasi dalam lumpur pemboran dan sebagai viscofier dalam lumpur untuk menjadi nilai rheologi lumpur.Kata kunci: Lumpur Pemboran, Kontaminas Batubara, Sifat Rheology, PAC-R.
