ABSTRAK OPTIMASI LAJU ALIR MASSA DALAM PURIFIKASI PENDINGIN RGTT200K UNTUK PROSES KONVERSI KARBONMONOKSIDA. Karbonmonoksida adalah spesi yang sulit dipisahkan dari helium pendingin reaktor karena mempunyai ukuran molekul relatif kecil sehingga diperlukan proses konversi menjadi karbondioksida. Laju konversi karbonmonoksida dalam sistem purifikasi dipengaruhi oleh beberapa parameter diantaranya konsentrasi, temperatur dan laju alir massa. Dalam penelitian ini dilakukan optimasi laju alir massa dalam purifikasi pendingin RGTT200K untuk proses konversi karbonmonoksida. Optimasi dilakukan melalui simulasi proses konversi karbonmonoksida menggunakan perangkat lunak Super Pro Designer. Laju pengurangan spesi reaktan, laju pertumbuhan spesi antara dan spesi produk dalam kesetimbangan reaksi konversi dianalisis untuk memperoleh optimasi laju alir massa purifikasi terhadap proses konversi karbonmonoksida. Tujuan penelitian ini adalah menyediakan data laju alir massa purifikasi untuk pembuatan dasar desain sistem purifikasi helium pendingin RGTT200K. Hasil analisis menunjukkan bahwa pada laju alir massa 0,6 kg/detik proses konversi belum optimal, pada laju alir massa 1,2 kg/detik mencapai optimal dan pada laju alir 3,6 kg/detik s/d 12,0 kg/detik tidak efektif. Untuk memdukung dasar desain sistem purifikasi helium pendingin RGTT200K maka laju alir massa purifikasi untuk proses konversi karbonmonoksida digunakan laju alir massa 1,2 kg/detik. Kata kunci: Karbonmonoksida, konversi, purifikasi, laju alir massa, RGTT200K.  ABSTRACT OPTIMIZATION OF MASS FLOW RATE IN RGTT200K COOLANT PURIFICATION FOR CARBONMONOXIDE CONVERSION PROCESS. Carbonmonoxide is a species that is difficult to be separated from the reactor coolant helium because it has a relatively small molecular size.  So it needs a process of conversion from carbonmonoxide to carbondioxide. The rate of conversion of carbonmonoxide in the purification system is influenced by several parameters including concentration, temperature and mass flow rate. In this research, optimization of the mass flow rate in coolant purification of RGTT200K for carbonmonoxide conversion process was done. Optimization is carried out by using software Super Pro Designer. The rate of reduction of reactant species, the growth rate between the species and the species products in the conversion reactions equilibrium were analyzed to derive the mass flow rate optimization of purification for carbonmonoxide conversion process. The purpose of this study is to find  the mass flow rate of purification for the preparation of the basic design of the RGTT200K coolant helium purification system. The analysis showed that the helium mass flow rate of 0.6 kg/second resulted in an unoptimal conversion process. The optimal conversion process was reached at a mass flow rate of 1.2 kg/second. A flow rate of 3.6 kg/second – 12 kg/second resulted in an ineffective process. For supporting the basic design of the  RGTT200K helium purification system, the mass flow rate for carbonmonoxide conversion process is suggested to be1.2 kg/second . Keywords: Carbonmonoxide, conversion, purification, mass flow rate, RGTT200K.

The main objective of this paper is to analyze the thermal performance of direct expansion solar assisted heat pump DX-SAHP(A) by numerical simulation in MATLAB and comparing it with the thermal performance of DX-SAHP(B) which has an optimized collector area and mass flow rate. Optimization is performed for high exergy efficiency using Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) optimization technique. The flat plate collector of solar water heater is used as the evaporator with refrigerant (R22).With the optimized value of mass flow rate as 0.055 kg/sec, width as 0.03 m and diameter of riser tubes as 0.021 m the performance of the optimized system has a maximum COP of 6.85 which is greater than the COP of DX-SAHP(A) and the final water temperature of is obtained 100 minutes earlier in the optimized system i.e. DX-SAHP(B) with compressor work less than the system A
