Process Description
The objective of the SPM-200 Pumping System process is to pump the two paraffins hexane (C6) and heptane (C7) to a downstream unit for further processing.
Instrumentation
The hexane feed flow loop is outfitted with upstream and downstream pressure indicators (PI-201 and PI-203). Pump discharge pressure (PI-202) is also provided. Flow is controlled by flow controller FIC-201.
The heptane feed flow loop is outfitted with upstream and downstream pressure indicators (PI-204 and PI-206). Pump discharge pressure (PI-205) is also provided. Flow is controlled by flow controller FIC-202.
Block valve V-201, V-202, V-203, and V-204 can be opened and closed with switches HV-201, HV-202, HV-203, and HV-204 respectively.
Primary feed pumps P-201 and P-203 can be turned on and off with the switches HS-201 and HS-203 respectively. Spare feed pumps P-202 and P-204 can be turned on and off with the switches HS-202 and HS-204 respectively.
