Abstract

Petroleum processing generally begins with a heating process, so equipment is needed to heat the crude oil before entering the fractionation column. This heating is closely related to the separation of fractions based on differences in boiling points. Heating at a fairly high temperature is used by a furnace, where the heat source comes from gas fuel. Based on the discussion above, furnace efficiency is fascinating to calculate as an indication of whether or not the furnace is operational. This efficiency calculation is also a reference for PT. Trans-Pacific Petrochemical Indotama to shut down and repair equipment, especially furnaces. This research aims to understand the furnace's working principles, determine the parameters that influence furnace performance, and calculate the efficiency of Furnace 201-H-001 in the Prefractionation unit. The results obtained in this research are that there are variables used to calculate thermal furnace efficiency. These variables are air temperature, fuel gas temperature, fuel gas flow, flue gas temperature, theoretical air requirements, and excess air in terms of efficiency and combustion reactions. The results of the furnace efficiency calculations were 78.03%, 77.34%, and 77.75% respectively. The minimum thermal efficiency value ranges from 75 - 80%, so it can be said that the furnace in this research is still suitable for use.

Abstract

Process water has an important role in the petrochemical industry as a steam plant and cooling process. Sea water reverse osmosis seawater is processed through a Reverse osmosis Membrane serves to reduce the value of Total Disolved Solids contained in seawater. The performance of Sea Water Reverse Osmosis can be seen from the value of Flux, Coefficient of Permeability to TDS value and Salt Rejection. This research was conducted in February – March 2022 located at the SWRO unit of PT TPPI Tuban Regency, the methodology used was quantitative descriptive analysis based on field data which was then processed using Microsoft Excel. The results showed that the flux value of a membrane affects SWRO performance where the flux value is directly proportional to TDS and inversely proportional to salt rejection. The permeability coefficient is directly proportional to TDS and inversely proportional to salt rejection. The largest flux result is 12.623 L/m2H permeability coefficient of 4508 L/m2. H.atm with TDS value of 420.88 mg / L and salt rejection of 97.844%. The flux is directly proportional to the permeability coefficient.
