Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the example.
In large facilities oil is typically sold through a LACT unit, which is designed to meet API Standards and whatever additional measuring and sampling standards are required by the crude purchaser. The value received for the crude will typically depend … Continue reading
Most oil treating on offshore facilities is done in vertical or horizontal treaters, such as those described in “Crude Oil Treating System“. Figure 2-8 is an enlargement of the oil treater in Flow Sheet. In this case, a gas blanket … Continue reading
The choice of separator operating pressures in a multistage system is large. For large facilities many options should be investigated before a final choice is made. For facilities handling less than 50,000 bpd, there are practical constraints that help limit … Continue reading
As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more than offset the cost of the additional separator, piping, controls, space, and compressor complexities. It … Continue reading
Figure 2-5 deals with a simple single-stage process. That is, the fluids are flashed in an initial separator and then the liquids from that separator are flashed again at the stock tank. Traditionally, the stock tank is not normally considered … Continue reading
