What should be done if the components above C3 in the hydrocracking dry gas cannot be removed completely, resulting in frequent liquid separation in the hydrogen production compressor?

Thread Content

Recently, the liquid separation tanks between compressor stages used for hydrogen production have been shedding liquid frequently, almost once every 10 minutes. Since the only feed material is cracked dry gas, it is assumed that there are high levels of components with molecular weights above C3 in this gas. Sampling analysis showed that these components account for about 20% v/v, and they mainly originate from the dry gas coming from the butane removal tower. Before making any adjustments, the operating parameters of the butane removal tower were a top pressure of 1.60 MPa, a top temperature of 75 degrees, and a temperature after water cooling of 28 degrees. Currently, the operating parameters of this tower are a top pressure of 1.65 MPa, a top temperature of 73 degrees, and a temperature after water cooling of 23 degrees. As a result, the interval between liquid separation events in the hydrogen production process has increased to one hour. However, this brings about problems such as higher pressures in the distillation tower and an increased risk of blockages in the pressure control systems. Could anyone please suggest other ways in which operations can be optimized?
