Untuk kelancaran pengoperasian Oily water separator, perawatan dan perbaikan harus dilakukan secara berkala agar tidak mengganggu pengoperasian kapal. Tujuan artikel ini adalah untuk menganalisis unjuk kerja mesin Oily Water Separator tipe CYF-1.OY pada proyek pembangunan kapal 2000 GT. Metode Eksperimen yang digunakan untuk menentukan kinerja mesin dan mengasumsikan pendekatan koreksi penilaian. Hasil dari performa mesin, waktu kerja mesin berbanding lurus dengan volume kapasitas sampah sehingga semakin banyak volume maka waktu yang dibutuhkan semakin lama tergantung. Efisiensinya hampir sama artinya hasil di bawah 5% dan masih dalam relevansi. Dalam pengoperasian dan penyetelan Oily Water Separator diperlukan pengamatan dan perhatian yang lebih, terutama untuk tampilan dan kapasitas spesifikasi mesin.

“…According to the available literatures, HRSG modeling of a cogeneration plant are performed with different approaches including energy modeling, [27][28][29] energy and exergy modeling, 30,31 exergo-economic modeling, 8,10,18,21 energy-economic modeling, 32,33 and the major prime movers used in cogeneration or CHP systems such as gas turbine 8,10,34,35 or diesel engine. 32,[36][37][38][39][40][41][42] Accordingly, the comprehensive modeling and optimization of fire tube HRSG in energy, exergy, and economic aspects for a gas microturbine cogeneration plant were not found in open literature.

This article aims to model and optimize the fire tube Heat Recovery Steam Generator (HRSG) used in a gas microturbine cogeneration of heat and power system. Here, six cases including a finless and finned tube (solid and serrated) HRSGs with the inline and staggered arrangements are optimized and compared using techno-economic assessment. Optimization of HRSG was carried out by applying two objective functions of minimizing the total annual cost as well as maximizing the exergy efficiency. Nondominated Sorting Genetic Algorithm II is used to find out the optimal values of design variables. The TOPSIS decision-making process is employed to choose the optimum point of the Pareto front. A 600 kW gas microturbine cogeneration plant is considered as a case study. The results revealed that the finless tube HRSG with an inline arrangement has the lower pinch and approach temperatures (3.5 • C and 3.1 • C, respectively), the higher steam mass flow rate (12.7%), the lower total annual cost (64 096$/year), and the higher exergy efficiency (60.6%). It is also found that using the staggered arrangement tube banks along with the solid fins in HRSG leads the total annual cost, the steam mass flow rate, and exergy efficiency increase up to 41.6%, 100%, and 12.6%, respectively. This means that the thermodynamic performance improvement will compensate the total annual cost increment. Furthermore, it is demonstrated that HRSG with solid fins and staggered arrangement with total annual costs of (90 810$/year), exergy efficiency of (73.2%), and steam mass flow rate of (4680 kg/h) has the best performance in comparison with other finned tube cases.

“…It has a similar principle for the steam Rankine cycle but using organic solvents with lower boiling temperatures than water, which allows the heat recovery of low temperature resources. It has been reported that the application of ORC for residual heat recovery has resulted in reduction of process operation costs [ 28 , 29 ]. The basic organic Rankin cycle (BORC) consists of 4 main units named as turbine expander, condenser, pump and evaporator.…”

Advanced process integration for supercritical production of biodiesel: Residual waste heat recovery via organic Rankine cycle (ORC)

Biodiesel production using supercritical methanolysis has received immense interest over the last few years. It has the ability to convert high acid value feedstock into biodiesel using a single-pot reaction. However, the energy intensive process is the main disadvantage of supercritical biodiesel process. Herein, a conceptual design for the integration of supercritical biodiesel process with organic Rankine cycle (ORC) is presented to recover residual hot streams and to generate electric power. This article provides energy and techno-economic comparative study for three developed scenarios as follows: original process with no energy integration (Scenario 1), energy integrated process (Scenario 2) and advanced energy integrated process with ORC (Scenario 3). The developed integrated biodiesel process with ORC resulted in electric power generation that has not only satisfied the process electric requirement but also provided excess power of 257 kW for 8000 tonnes/annum biodiesel plant. The techno-economic comparative analysis resulted in favouring the third scenario with 36% increase in the process profitability than the second scenario. Sensitivity analysis has shown that biodiesel price variation has significant effect on the process profitability. In summary, integrating supercritical biodiesel production process with ORC appears to be a promising approach for enhancing the process techno-economic profitability and viability.
