num oxide from bauxite. The process has been refined and improved since its inception. Fig. 2.2 shows that the production of alumina is a complex chemical process. The alu-mina content of bauxite ores varies from one deposit to another, and methods of treat-ment differ accordingly (see 16.1.2). This means that each alumina plant is almost tailor-

UOP HF Alkylation Process | FSC 432: Petroleum Refining
UOP HF Alkylation Process. Figure 8.8 shows a flow diagram for a UOP HF alkylation process [4]. Olefin and iso-butane feed streams are dried to remove water before they are mixed with the iso-butane recycle stream. The mixture is fed to the reactor, where it is highly dispersed into an incoming stream of acid catalyst.
