Abstract

The heating stage of oil and gas refining commences with a heat exchanger. Using the pressure drop method and dirt factor in conjunction with the utmost standard permissible limit is one method of evaluating the thermal efficiency of a heat exchanger. This is performed to ascertain the value of the pressure drop, or pressure drop, which is directed at the fluid passage in the shell and pipeline. Moreover, a dust factor value is necessary to account for the potential accumulation of impurities and scale on the walls outside the heat exchanger conduit. The dust factor value is the maximum value that the parameter permits to ascertain the feasibility of the heat exchanger. Heat Exchanger 011-E-112 in the Fuel Oil Complex Unit The results indicate that heat exchanger 11E-112 can still be utilized despite the necessity for design enhancements. The design data for the shell is 1.7 psi, and the tube is approximately 18.92 psi. The Dirt Factor values for the shell and tube are 0.017 BTU/hour ft2°F and 0.034 BTU/hour ft2°F, respectively. The tube pressure drop value is 130.32 psi, while the shell pressure drop value is 2.53 psi.

Abstract

A heat exchanger (HE) is a heat exchanger that has a vital role in the oil and gas processing industry. Especially in the Fuel Oil Complex I (FOC I) unit, which is tasked with separating crude petroleum into fractions such as LPG, light naphtha, heavy naphtha, kerosene, Light Gas Oil (LGO), Heavy Gas Oil (HGO) and long residue. The continuous use of heat exchangers will cause fouling over time. The Cilacap oil and gas processing industry uses a shell and tube type heat exchanger because it has cost, fabrication, and work advantages. The evaluation results of the comparison of the fouling factor (Rd) and pressure drop values on the design data and actual data on 1 June - 30 July 2024 show that the actual fouling factor (Rd) value is greater than the design fouling factor (Rd) value. While the actual ∆P pressure drop shell side and tube side values are smaller than the design pressure drop values because the actual flow rate is much smaller than the design data flow rate. The recommendation is periodic evaluation and cleaning of accumulated dirt, mud, and scale found on the shell and tube walls to maintain heat exchanger performance.
