PP Plant 3rd train at PT Chandra Asri Petrochemical is a plant that produces impact copolymer products. The production process begins with a chemical reaction in reactor C-34301. The cycle gas cooler E-343012 is equipment that has a critical role in the polymerization process. Polymerization is closed loop cycle and produces a cycle gas that needs to be cooled before re-entering reactor. The process of heat transfer is carried out by cycle gas cooler, a single pass shell, and a tube heat exchanger. Cycle gas is circulated in the tube side, then cycle water is circulated by counter-current flow in the shell side. The set point is meet the design recommendation of Tho 55 0C. In 2019, a new cycle gas cooler E-34302 was installed with design modifications and improvement but there is no performances comparative analysis of the two equipment. The analysis was performed by calculating U value, fouling factor, and effectiveness. The analysis found that the effectiveness of new cooler is higher than the existing. The highest value of the new cooler is 87% and the lowest is 65%. The highest effectiveness of the existing cooler is 76% and the lowest is 43%. The correlation between flow rate and effectiveness is that fewer of cycle gas circulated into cooler than we had the higher effectiveness from the heat transfer process.Downloads
