Process Improvement And Microbial Characterisation Of Biological Nitrogen Removal For Tropical Wastewater With Low Chemical Oxygen Demand/Nitrogen Ratio, How Seow Wah
Student Works (2020-2029)
Malaysia has one of the most established biological nitrogen removal in wastewater treatment plants (WWTPs) among the developing Southeast Asian countries. The current WWTPs’ design and operating guidelines in Malaysia are mainly derived from other developed countries with more experiences in operating biological nitrogen removal. These design guidelines are good practices for WWTPs in the temperate climate region, but may not be optimal for the local wastewater characteristics and tropical climate in Malaysia. The local wastewater industry is keen to improve the design and operation of WWTPs to reduce the energy consumption and operating cost, which helps to foster a …

Cfd Modelling Of Multiphase Flow In Static Mixer, Silverrajan Viknesvaran
Student Works (2020-2029)
Modelling of Multiphase flow through a Kenics static mixer were presented in this paper. Multiphase mixing is a challenging process in industries such as pharmaceutical, food and petroleum since two-different phases can be immiscible towards each other. Stirred tank mixing is the most common method used in industries. However, this type of method costs a lot in terms of energy and manpower specially when mixing immiscible liquids. Hence, The Kenics Static Mixer could be a good solution for multiphase mixing when its correctly configured and studied. Two phases used in this paper were aqueous solution: refined CMC as continuous phase …

Student Works (2020-2029)
Malay-Sino Chemical Industries Sdn Bhd (Lahat) is a chlor-alkali industry consist of Emergency Chlorine Gas Handling Facility (ECGHF) which have the tendency to affect the plant workers and nearby residential area in the event of accidental chlorine gas release. HAZOP tool with risk assessment was used to identify the hazard and quantifying the hazards in order to prioritize the recommendations at the ECGHF. Possible incident scenario was selected from the HAZOP outcome which was the chlorine gas release from the stack due to scrubbing flow failure. The consequences of the released chlorine gas to the atmosphere was simulated by using …

Thermodynamic Analysis And Optimization Of Organic Rankine Cycles Using 1-Butylpyridinium Tetrafluoroborate As A Geothermal Fluid, Kazemi Shabnam
Student Works (2020-2029)
Organic Rankine cycle (ORC) is a promising technology for electricity generation by utilizing heat sources at low to moderate temperature that ranges between 80-350° C. In the present work, an ionic liquid (1-butylpyridinium tetrafluoroborate, C9H14NBF4), a known green chemical and non-volatile compound with good thermal and chemical stability, significant heat capacity, low vapor pressure and a wide liquid temperature range (25 to 459 °C), is utilized as a geothermal fluid. Simulation and optimization were conducted for a basic organic Rankine cycle (basic ORC), a regenerative organic Rankine cycle (RORC) and a two-stage evaporative organic Rankine cycle (TSORC) by maximizing exergy …

Waste Cooking Oil Classification Using Artificial Intelligence Technology, Kar Sin Lau
Student Works (2020-2029)
Palm oil – one of the most common edible oil consumed in Malaysia. It is because Malaysia is one of the countries which supply palm oil to the global market and it is cheap to obtain for the consumer in Malaysia. Most of the Malaysian consume it via food preparation such as deep-frying and cooking. However, due to widely available for Malaysians, consumers also lacking awareness in dealing after using the edible oil. Most of the household consumers discard excess waste cooking oil (WCO) into sewage and with courtesy, some of them stored them in containers and sell to NGOs. …
Simulation And Optimal Control Of Crude Oil Separation Process At Offshore Facilities To Improve Efficiency Of Oil And Condensate Recovery, Yee Kai Chin
Student Works (2020-2029)
Crude oil separation process is the most crucial process in offshore production facilities in ensuring the well fluid is separated efficiently and persistently. Waxy crude or sluggish feed stream is the major disturbance that could cause operational issues and production loss due to process upset. The main objective of this research is to model offshore crude oil separation process and introduce state space control to optimize the control of total liquid and water level within the permissible range as well as to evaluate the effect of disturbances to the controls. This work presents two different modelling methods in developing three-phase …

Effects Of New And Recycle Flux On The Mechanical Properties Of Submerged Arc Welded (Saw) Line Pipe Grade X52m And X65m, Taib Meor Mohd Adli
Student Works (2020-2029)
Two line pipe grade X52M and X65M were manufactured using submerged arc welding process. For each grade, two different welding flux condition were simulated, i.e. 100% new flux and 100% recycle flux. The flux used was aluminate basic type trade name OP 132. The outside diameter and wall thickness for X52M was 610mm x 12.7mm and for X65M was 762mm x 14.3mm. Lower weld re-entrant angle and higher weld bead height were observed in recycle flux condition. Lower weld manganese content recorded in recycle flux condition. And lower mechanical tests (i.e. tensile, impact, and hardness) value reported for recycle flux …
