3 million tons per year medium oil conversion unit: In a dry gas seal control panel, we got the "nitrogen differential pressure" right.
Startup window, sudden load drop, emergency shutdown — the seal gas pressure of the recycle hydrogen compressor always loses balance during those most vulnerable few minutes. The HIGH-PA 4AG-1.1 all-pneumatic nitrogen boosting unit achieved the successful startup of the entire plant within 72 hours.

Benchmark for Energy-Saving Upgrade of Ammonia Synthesis: HIGH-PA Gas-Driven Booster Guards the "Lifeline" of Dry Gas Seals
In the energy-saving upgrading project of the ammonia synthesis system at Hebei Tianyuan Chemical, the HIGH-PA gas-driven booster is installed in the dry gas seal control panel. It stably supplies seal gas under low pressure difference conditions such as startup, shutdown and reflux, building a solid line of defense for the long-period safe operation of the syngas compressor.
