Perancangan LP CO2 Condensate Separator pada Proyek Revamp Of Ammonia Plant-2 di Bontang, Kalimantan Timur

Abstract

The development of industry in Indonesia has led to an increasing demand for chemical raw
materials for industry. Therefore, Revamp of Ammonia Plant-2 is a project that aims to modify an ammonia
plant, where there is the addition of a pressure vessel, namely LP CO2 Condensate Separator, which functions
as a separator between CO2 and water. Things that are considered when designing include internal pressure,
external pressure, maximum allowable working pressure and calculation of seismic and wind loads with
reference to ASME Section VIII Divison I and ASCE 7-10 and modeling is carried out with software. Based on
the calculation results, the shell thickness is 0,482 inch and the head thickness is 0,325 inch. The MAWP value
obtained is qualified with a value greater than the design pressure. then for the MAEP value obtained is also
qualified with a value greater than 15 psi. The maximum deflection value due to wind load is 0,00845 inch and
the base shear moment value does not exceed 80% of the base shear due to earthquake load of 1049,14 kips.ft
> 24,395 kips.ft.
