“…Such an approach allows for determining the optimal parameter of the facility providing the effective conduct of the process of small particle aggregation. For his reason, the issues of mathematical modeling of particle motion, investigation and elaboration of self-cleaning methods of the internal surfaces come to the fore and are important today [27][28][29][30].…”

The purpose of this article is to describe the method of calculation of the motion of particles in the filter-coalescer wastewater treatment based on the mathematical description of the motion of the cleaning fluid and the particles in the channel coagulator. It is found that fine particles in the coagulator move in a stream so that the process of consolidation and coalescence occurs at specific sites in the gap between the cones, with little flow velocity vector changes in direction and magnitude that the process provides an efficient aggregation of particles. The length of this section should be sufficient to ensure that the bulk of the particles reach a critical size. This allows the particles to migrate subsequent channel sections coagulator holding particles in the flow, and eliminating such deposition of particles on the internal surfaces of the device even when moving within the annular gap. The scheme of the electromagnetic filter of the coagulator, the two-dimensional scheme of the magnetic coagulator, the scheme of epure of speed vectors in the canal of the coagulator and the scheme of particle interaction in the canal of the coagulator are given too.

“…The gas elds of the Sylhet region are located in the Surma basin, a young deltaic sedimentary basin (Hossain & Howladar, 2022), characterized by a negative gravity anomaly, minimal terrain, and active subsidence (Johnson and Alam, 1991). The basin contains a deep deposit of Miocene sedentary column, which makes it a unique hydrocarbon province in northeastern Bangladesh.…”

The current research was conducted in the Sylhet gas-fields area of Bangladesh to evaluate the toxicity of trace metals (TMs) and associated health risks. Gas well-produced water, gas field discharge water, and drinking water surrounding the gas fields were collected for analysis. This study analyzed both carcinogenic and noncarcinogenic TMs such as Cr, As, Co, Cd, Fe, Ni, Mn, Zn, and Pb, as well as physical parameters pH and EC in the collected samples. The Fe and EC concentrations in produced and discharged water samples were found to be incredibly high. The average concentrations of TMs in produced water samples during the summer and rainy season were found to be: Fe > Mn > Zn > Ni > Co > Cu > Cr > Pb > As > Cd. The observed metal concentration in discharge water was higher during the summer than rainy season. Most samples met national and international standards for trace elements, while a few samples exceeded the threshold value. The Heavy Metal Evaluation Index (HMEI) results indicate that the majority of produced water is highly polluted, while discharge and drinking water are moderately to lowly polluted. The Environmental Pollution Index (EPI) indicates environmental pollution for some produced water samples, while it indicates a moderate to low risk for discharge and drinking water samples. The source allocation of heavy metals (HMs) was determined using positive matrix factorization. However, all water samples have an ecological risk index of less than 150, indicating lower risk. Furthermore, the Heavy Metals Toxicity Load (HMTL) was found to be below the allowable toxicity load for all water samples, indicating minimal contamination in the studied water. The non-cancer hazard score (HI) of the studied HMs is greater for children and females than for males. The cancer risk from Ni is a concern, while the cancer risk from Cd and Cr is also a matter of concern.

“…Based on research conducted by Lestari, A. S. (Lestari, 2021) in a Public Health Journal, the potential for noise hazards originates from the water injection pump (WIP) pump engine at the oil collection station and in the power plant, which originates from generator engines and fan radiators which function as providers electrical energy for all areas of the company. Meanwhile, according to Hossain and Howladar (Hossain & Howladar, 2022), several things that can cause noise in equipment and machines include operating obsolete production machines with non-routine maintenance systems and machines often operated with high work capacity in long operating periods-at the same time, measuring noise exposure in the HCC area of PT. X exceeds the TLV, namely Leq of 68.1 dBA; Leq should be noise exposure by the Regulation of the Minister of Health of the Republic of Indonesia No.…”

The hydro cracker complex (HCC) operating area is one of the areas with the most use of chemicals, and several workers complain about the noise in that area. This research determines the level of health hazard risk through a health risk assessment (HRA) focusing on physical, chemical, and biological hazards in the HCC area aims to improve the health status of workers and as a basis for developing occupational health programs to minimize the risk of occupational diseases. This study used primary data (walkthrough survey, interviews, heat stress measurements, noise, lighting, chemicals, fungi, and bacteria) with a cross-sectional method referring to the International Council on Mining & Metals (ICMM). The dangers of gasses and chemicals are the most common hazard in the HCC area. Based on the risk assessment, five hazard ratings with the highest risk were obtained, namely noisy environment (extreme), H2S gas (extreme), heat stress (extreme), NH3 gas (high risk), and hydrocarbon vapors (high risk). Existing controls and control recommendations must be applied comprehensively and consistently so that the company can accept the resulting residual risk value. Abstrak: Area operasi hydro cracker complex (HCC) merupakan salah satu area yang paling banyak menggunakan bahan kimia, dan beberapa pekerja mengeluhkan kebisingan di area tersebut. Penelitian ini menentukan tingkat risiko bahaya kesehatan melalui health risk assesment (HRA) yang berfokus pada bahaya fisik, kimia, dan biologi di area HCC yang bertujuan untuk meningkatkan status kesehatan pekerja dan sebagai dasar untuk mengembangkan program kesehatan kerja untuk meminimalkan risiko penyakit akibat kerja. Penelitian ini menggunakan data primer (walkthrough survey, wawancara, pengukuran tekanan panas, kebisingan, pencahayaan, bahan kimia, jamur, dan bakteri) dengan metode cross-sectional mengacu pada International Council on Mining & Metals (ICMM). Gas dan bahan kimia merupakan bahaya yang paling umum terjadi di kawasan HCC. Berdasarkan penilaian risiko diperoleh lima peringkat bahaya dengan risiko tertinggi, yaitu lingkungan bising (ekstrim), gas H2S (ekstrim), tekanan panas (ekstrim), gas NH3 (risiko tinggi), dan uap hidrokarbon (risiko tinggi). Pengendalian yang ada dan rekomendasi pengendalian harus diterapkan secara komprehensif dan konsisten agar perusahaan dapat menerima nilai residual risk yang dihasilkan.
