Manufacturing of key equipment for aromatics production technology
Ruihua aromatics production technology can be used to produce benzene, toluene and xylene products. This technology is highly adaptable to the market, and the product scheme can be adjusted according to demand, and it is very competitive in small and medium-sized industrial applications.
The raw material for this technology can start from benzene or toluene. When the starting material is benzene, benzene is firstly alkylated with methanol to produce toluene, and then toluene is form-selectively disproportionated to produce high-concentration crude p-xylene and benzene. Benzene is recycled. The crude p-xylene is refined by crystallization. High-purity para-xylene, mixed xylene and a small amount of C9 aromatics; when the starting material is toluene, toluene is directly disproportionated to produce crude para-xylene and benzene. The product scheme is high-purity para-xylene, benzene, mixed xylene and a small amount of C9 Aromatics.
The technology consists of two parts: benzene and methanol alkylation and toluene shape selective disproportionation. The configuration of the alkylation and disproportionation parts can be matched according to the scale, or different proportions can be adopted according to the plant conditions.
Some key equipment of the process is shown in the figure, and the details are shown in the table below:
The benzene used for alkylation can be petroleum benzene or coking benzene; the raw material methanol needs to meet the requirements of GB 338-2011.
