In order to cater for increased demand for natural gas (NG) by the industry, Malaysia is required to import liquid natural gas (LNG). This is done through PETRONAS GAS Sdn Bhd. For LNG regasification, two regasification terminals have been set up, one in Sungai Udang Melaka (RGTSU) and another at Pengerang Johor (RGTPJ). RGTSU started operation in 2013 while RGTPJ began operation in 2017. The capacities of RGTSU and RGTPJ are 3.8 (500 mmscfd) and 3.5 (490 mmscfd) MTPA, respectively. RGTSU is an offshore plant and uses an intermediate-fluid-vaporization (IFV) process for regasification. RGTPJ is an onshore plant and employs open-rack vaporization (ORV). It is known that a substantial amount of cold energy is released during the regasification process. However, neither plant captures the cold energy released during regasification. This techno economic study serves to evaluate the technical and economic feasibility of the cold energy available during regasification. It was estimated that approximately 47,214 and 88,383 kWh of cold energy could be generated daily at RGTPJ and RGTSU, respectively, during regasification processes. Converting this energy into RTh at 70% thermal efficiency, and taking the commercial rate of 0.549 Sen per RTh, for the 20-year project life, an internal rate of return (IRR) of up to 33% and 17% was estimated for RGTPJ and for RGTSU, respectively.

The fish shelter port (TPI) is a need that needs to be prepared by local village officials and the government for every coastal village in Bengkalis Regency. This research was conducted in the Berancah village of Bantan District. The analysis in this study describes the economic feasibility mathematically for the construction of a fish storage port (TPI) by calculating the cost ratio (B / C ratio) benefit analysis, payback period (PP), net present value (NPV), and internal rate of return ( IRR). The results obtained from the NPV value (3,661,267,645), BCR value (0.943), IRR value of 10.01%, and PP are in the period of 30 years. Taken as a whole by standardizing the calculations, it can be concluded that the planned construction of a fish shelter in Berancah village is considered not economically feasible, but economic analysis is not merely a benchmark for feasibility, reviewed for the future many benefits will be received by the community around the location of the development plan so that it can improve the welfare of the community in Berancah village.

Liquid Natural Gas

Natural gas is conventionally transported in its liquid form or Liquid Natural Gas (LNG). It is then transported using cryogenic insulated LNG tankers. At receiving terminals, LNG is regasified prior to distributing it through gas distribution system. Seawater has been used as the heat source, which leads to vast amount of cold energy discarded into the water. This work presents the use of LNG cold energy around Melaka Refining Company (MRC). The cold energy is utilized in power generation, propylene refrigeration cycle, and air separation plants. These systems are designed and simulated using a commercial process simulation software. Capital cost (CAPEX) function and revenues of each system are further developed as a function of LNG flowrates. These developed correlations are then used in an optimization problem to seek for the most profitable scenario. The results show that utilizing LNG for air separation unit yields the highest profit compared to power generation and refrigeration plants.

A process of hydrogen storage in the form of hydrate by utilization of liquefied natural gas(LNG) cold energy was proposed. Hydrogen was recovered from exhaust gas by pressure swing adsorption method, and formed gas hydrate with ice powder under a pressure of 35 MPa and a temperature of 140 K. The process analysis was carried out with partially numerical simulation by Aspen Plus and theoretical calculation. The results show that the energy consumption of hydrogen stored in the hydrate form is 12058 kJ/(kg.H2) and of this hydrogen storage process, the ratio of spent energy to stored energy is 0.10 , which is superior to the most of the other method. The research indicated that if there is cold energy with low temperature available, hydrogen stored in the hydrate form is a method of feasible and energy-efficient.
