Dec
Heater tune-up The Air and Fire Draft Regulation Diagram (DRAFT diagram for short), shown in the following figure, is a practical tool for controlling draft and excess oxygen in process heaters. This diagram, based on Figure 19 (Natural Draft Heater Adjustment Chart) of the API RP 535 standard, more explicitly clarifies the application of single […]
Continuous Operational Tune-up (COT) of Fired Heaters
01
Mar
Continuous Operational Tune-up (COT) of process furnaces is the fastest and cheapest option to mitigate CO2 emissions in oil refineries. CO2 emissions in petroleum refineries Process heaters in petroleum refineries consume large volumes of fossil fuels and emit proportional amounts of CO2 into the atmosphere. Most of these heaters have a natural draft design and […]
