Abstract

The liquid concentration and temperature dynamic behavior of a stirred tank heater with bypass stream (STHB) has been studied experimentally. A cylinder tank was designed and arranged for experimentation in laboratory. The tank has two input streams, stream-1 (salt solution with its volumetric rate of f1 [cm3/sec], salt concentration of cg1 [gr/cm3]) and stream-2 (water-stream with its volumetric rate of f2 [cm3/sec]). A part of the stream-1 was bypassed (f3 [cm3/sec]) and mixed with the output stream of the tank (f5 [cm3/sec]). The electric heater was employed for heating liquid in the tank. Since the tank was designed overflow, the liquid volume in tank was always constant. In this work, the mass and thermal disturbance load has been made based on step increase and decrease. Those disturbance included the changes of the bypass volumetric rate (f3), the water volumetric rate (f2), and the electric heat (qe). The dynamic behavior of the STHB has also been explored. As can be seen from our investigation in laboratory, the STHB produced a stable response. Furthermore, the open loop dynamic simulation using computer programing was also done, and its simulation results were compared with the experiment data from laboratory. The developed mathematical model of the STHB has been solved numerically. Scilab software was chosen to examine such mathematical model. This study also revealed that the trends of simulation results were quite similar with those in our experiment results.

Abstract

The Study of CO2 injection to enhance oil recovery through several stages before implementation on the pilot and full scale projects in the field had been done succesfully. The final stage of this study has been made by modeling of network and CO2 injection surface facilities that can be implemented in J Field. The developed model which is run by production simulator gave significant results both on the re-pressurized stage and CO2 flooding stage. This study showed that the implementation of CO2 injection could be run well. With the model validation through static and dynamic run, this study also reavealed that the network model and surface facilities could work properly.

Abstract

This research was aimed to design process control configuration in the Pure-Capacitive-Two-Tank-in-Series (PCTTS) quantitatively by using Relative Gain Array (RGA) method. Two square tanks were designed and arranged in series for investigation in laboratory. The electric heater was equipped in the tank T-01. Water was used as a fluid which is assumed that its density and heat capacity were constant. The feed water was flowed to tank T-01 and heated with an electric heater. Water of tank T-01 was then pumped to tank T-02. The pump volumetric rate can be adjusted by changing the pump voltage. This research was done through 2 procedures as follows: preliminary experiment and open loop RGA experiment. The preliminary experiment has given the steady state parameters as follows: the input and output volumetric rates of the 2 tanks were 104 cm3/second, liquid levels of tank T-01 and T-02 were 14 cm, liquid temperatures in tank T-01 and T-02 were 33.5oC, electric heat energy was 1520 watt,  and pump voltage was 66.5 volt. Based on degree of freedom analysis, there were 3 variables of PCTSS system need to be controlled (CV); they were liquid temperature in tank T-01 (T1), liquid level in tank T-01 (h1), and liquid level in tank T-02 (h2). In RGA experiment, the manipulated variable candidates (MV) were changed manually based on the step function and its output (CV) responses were also be recorded. RGA calculation has resulted 3 couples of CV-MV as follows: T1-qe, h1-vpu, and h2-f2. Furthermore, study on the tuning of control parameters and closed loop simulation need to be done to examine performance of the resulted control configuration of PCCTS.

Abstract

The liquid concentration dynamic behavior of a 10 L mixing tank has been studied experimentally. Tank with volume of 10 liter are designed and arranged for experimentation in laboratory. The tank has two input streams, stream-1 is the water-stream with its volumetric rate of f1 [cm3/sec] and stream-2 is salt solution with its volumetric rate of f2 [cm3/sec] and salt composition of c2 [gr/cm3]. Since the tank is designed overflow, the liquid volume in tank is always constant. In this work, the mass disturbance load has been made based on step increase and decrease. Those disturbance include the changes of the flow-rate input (f1 and f2) and the concentration of the input stream (c2). The dynamic behavior of mixing tank system has also been explored. As can be seen from our investigation in laboratory,the mixing tank with volume capacity of 10 liter produces a stable responce. Furhtermore, the open loop dynamic simulation using computer programing is also done, and its simulation result are compared with the experiment data from laboratory. The developed mathematical model of the mixing tank system has been solved analytically by laplace transform. The trends of simulation results are quite similar with those in our experiment results.

Abstract

This researchcontinued the previous work by Hermawan, Y.D. et al., 2016. The goals of this research wereto tune the process control parametersand to do the closed loop dynamic simulationfor the proposed control configuration of Pure-Capacitive-Two-Tank-in-Series (PCTTS) with an electric heater in tank T-01.The proposed control configuration consisted of 3 couples of CV-MV as follows T1-qe, h1-vpu, and h2-f2. The open loop experiment results would be used for tuning of PID control parameters. In this work, the PID control parameters were tuned quantitatively by using Process Reaction Curve (PRC) method. The controllergain (Kc) for temperature control of tank T-01 (TC-01), level control of tank T-01 (LC-01), and level control of tank T-02 (LC-02) has been found as follows: 364.8 watt/oC, -2.3 volt/cm, and -12.9 cm2/second , respectively. The integral time constant (tI) for 3 controllers were as follows: 60 second, 60 second, and 90 second, respectively. The derivative time constant (tD) for 3 controllers were as follows: 15 second, 15 second, and 22.5 second, respectively. Furthermore, the proposed control configuration and resulted tuning parameters were examined through rigorous dynamic simulation by using scilab software. The input volumetric rate disturbance (with amount of ±29%) was made based on step function. The developed of closed loop state equation was solved numerically. Integral of the absolute value of the error (IAE) for TC-01, LC-1 and LC-2 were 73, 1686, and 695, respectively. The dynamic simulation results showed that the proposed control configuration with its tuning parameters gave a stable response to a change in the input volumetric rate. This study also revealed that the PID controller gave fastest responses compared to P and PI controller.

Abstract

This research studies the temperature dynamic behavior of non-interacting-tank (NIT) with recycle-stream which is frequently used in industries. Two tanks with volume of 25 liters are designed and arranged in series for experimentation in laboratory. Part of liquid from Tank-2 is recycled back to the Tank-1. In this work, the liquid volume of both Tank-1 and Tank-2 are remained at constant value. The heat disturbance load has been made based on both step increase and decrease. Those disturbances include the changes of temperature in input (T i) and recycle (TR) streams. The temperature dynamic behavior of NIT system has also been explored. As can be seen from our investigation in laboratory, both of Tank-1 and Tank-2 in NIT system produce a stable response to the disturbance change in temperature of the input and recycle streams. Furthermore, dynamic simulation using computer programming is also done, and its simulation results are compared with the experiment data from laboratory. The developed mathematical model of the NIT system is solved numerically. Such mathematical model is rigorously examined in Scilab software environment. This research also shows that the trends of temperature dynamic simulation results are quite similar with those in our experiment results.
