Gulei Petrochemical optimizes technology to reduce energy consumption of styrene unit

A few days ago, Fujian Gulei Petrochemical Company established a technical research team to analyze in detail the problems existing in the styrene plant, and through a series of optimization adjustments, the overall energy consumption of the plant has been greatly reduced
.

Previously, the company exhausted the dehydrogenation tail gas to the torch, and increased the amount of methane hydrogen to increase the temperature of the steam superheater to ensure the successful activation of the dehydrogenation catalyst.
However, nearly 3 tons of dehydrogenation tail gas per hour could not be recycled, resulting in energy consumption.
higher
.
After a large amount of data calculation and analysis and demonstration, the technical research team carried out technical transformation on the fuel gas system of the Changming Lamp from the aspects of process adjustment, equipment optimization, parameter change, etc.
, adjusted the fuel gas pressure interlock value of the steam superheated furnace, and organized manufacturers to adjust the combustion Optimized the device, finally broke through the technical bottleneck, and completely solved the problem of "stuck neck" in the production process
.

After technical transformation, the comprehensive energy consumption of the company's styrene plant has been greatly reduced, and it is expected to save more than 20,000 tons of fuel gas every year
