Abstract

LNG (Liquid Natural Gas) is a liquefied natural gas, with composition of 87% - 96% methane, 1,8-5,1% ethan, 0,1-5,1% propane and other compounds. The composition of natural gas (LNG formation) varies depending on the source and the process of its formation. Methane gas in LNG has odorless, non-corrosive and non-toxic properties (Air Products, 1999). LNG is basically an alternative method to deliver gas from producer to consumer. When cooled to -162˚C at 1 atm pressure, natural gas becomes liquid and its volume decreases up to 600 times (Handbook of Liquefied Natural Gas, 2014). With such a large volume reduction, liquefied natural gas (LNG) can be transported through the Tanker Ship and the ISO Tank Truck. PT Badak NGL has 3 (Three) T.U.K.S (Terminal For Ownership) As Tanker Ship Facilities and 1 (One) LNG Filling Station as a means of filling LNG to ISO Tank. Development of business process of PT. Badak NGL leads to an increase in LNG filling Station capacity. Along with the plan to increase the filling station capacity, the problem of BOG (Blow of Gas) wastage along with some LNG to ground flare becomes a serious concern. When the number of fillling stations is only 1 (one) station, the BOG wasted condition is not significant. However, with plans to increase the number of filling stations, BOG wasted need to be considered to be fully utilized. Therefore, there is a thought to utilize BOG to become more economic value, through the design of blowdown line on LNG ISO Tank filling station. In the Design of this line Blowdown, Using Pipe Ø2 "(PIPE BE 40S SS A312-TP305 SMLS) interconnecting with Pipe Ø6" (PIPE BE 40S SS A312-TP305 SMLS) BOG Header of new Filling Station under construction (Beginning January 2018 ).

Abstract

In Badak LNG the role of the cooling water pump is very important, and becomes the main support for transferring sea water where the water is used in the cooling process of industrial machinery or as emergency safety for firefighters. Water pump cooling has a hayward strainer that serves to filter water with a smaller filter so that the cooling water that is sent is completely free of dirty water. The purpose of this final project is to find out the main causes of the performance degradation of the EF cooling water pump due to the barrier to the hayward strainer which results in lower pressure on the cooling water. The methodology applied was based on field observations and conducted a solidwork simulation test. Field observations show that when more than one hayward strainer is in backwash, the effectiveness of backwash release decreases because the main disposal of the hayward strainer becomes one. The solidwork simulation found that the pressure on the Hayward train E strainer was high enough to create back pressure and limit the flow of the Hayward strainer outlet. By performing actual simulations by only running only one exhaust system at Hayward train E trainer has improved performance on the hayward strainer system. The performance analysis of the cooling water pump was carried out to determine the cause of the pump pressure drop on the hayward strainer and it was found that the main cause of performance was due to back pressure disposal, the pressure was increasing at each outlet of the Hayward strainer which had more distance to the outlet drain. Taking into account the problem of back pressure, separating the train E and F cooling water pump lines is a good choice. After simulating solid work, the separation of the E train line and the F colling water train shows an increase in the performance of the cooling water pump system because the Hayward strainer runs well so that the pump pressure is maintained for the industrial engine cooling needs.
