Pump Station Design

Method A packed-bed throwaway system to remove organic pollutants from oily waste stream. System component A contactor system, and a pump station designed for a contact time of 30 min and hydraulic loading of 162 L/min/m2 (4gpm/ft2).

Crude oil vapor pressure limitations for pipeline delivery may be comparable to those for tanker loading. However, a pipeline can be specifically designed as a high vapor pressure system to handle gas liquids components mixed with the crude oil, and it is quite possible that North Sea oil pipeline systems will be developed in this manner. It is not expected to be feasible to recover NGL components separate from oil and gas on the offshore platforms and construct separate NGL pipeline systems. It also may not be possible in every field to design a separation system which meets both gas specifications and low crude oil vapor pressure specifications unless an intermediate product is also made. This will be more fully discussed later In this paper. A high vapor pressure crude system will have an NGL separation and fractionation plant at the onshore pipeline terminal. The vapor pressure limitation for onshore crude deliveries will be fixed by TVP limitations at pump station suction conditions.

If the liquid electrolyte design is selected for the electrolyzer, the optimization controls in Figure 4.1 (gatefold) include the electrolyte balancing controls based on the valve position control (VPC-32) of the variable-speed pumping station (VP-6). These controls are the same as those described for VP-1 and elaborated on in Chapter 2, Section 2.17.2. The power distribution controller (PoC-15) serves to control the electric power sent to the electrodes of the electrolyzer, and the pressure controller PC-14 serves to maintain the H2 pressure in the distribution header at around 3 bar (45 psig). 

When designing a pumping station or specifying sizes of pumps, the engineer refers to a pnmp characteristic cnrve that defines the performance of a pump. Several different sizes of pumps are used, so theoretically, there should also be a number of these curves to correspond to each pnmp. In practice, however, this is not done. The characteristic performance of any other pnmp can be obtained from the curves of any one pnmp by the use of pump scaling laws, provided the pumps are similar. The word similar will become clear later. 

Specifically, system characteristic is the relation of discharge Q and the associated head requirements of this system which, again, does not include the pump arrangement. The pump arrangement may be called the pump assembly. In the design of a pumping station, both the pump characteristics and the system characteristic must be considered simultaneously. 

Initially (1933), the maximum output of the filter plant and pumping station was only 200,000 cubic meters a day (53,000,000 gallons per day). The present output of the ozone plant is 300,000 cubic meters (79,000,000 gallons per day), which has already been reached and even exceeded for short periods. As head losses are lower than anticipated, it should be possible to double the design output to 600,000 cubic meters a day, if the ozone production could be suitably increased during peak demand periods. 

The book includes summaries of the necessary theories behind the design of systems together with practical guidance on selecting most types of electrical equipment and systems that are normally encountered with offshore production platforms, drilling rigs, onshore gas plants, pipelines, liquefied natural gas plants, pipeline pumping stations, refineries and chemical plants. 

Pumping stations and so on should all be constructed with the same design philosophy.
