Tanks and pumps

All parts in contact with the process water, except gaskets and membrane of valves, must be AISI 316L stainless steel (distillator, tubing, heat exchangers, sensors, valves, fittings, tank, pump, and all instrumentation). 

Water was used as the liquid phase. The liquid delivery system consists of a feed tank, pump, and a flow indicator. Water is recycled, as well as added if necessary, to maintain a constant suction head at the pump. The in-house air system was used as the gas delivery system through a rotameter. Air enters the setup at a point below the packing. Two taps are mounted at the inlet and outlet of the packed column for pressure drop measurement. 

In its simplist form, the major hardware components of the ultrafiltration system are the storage tank, pump, and membrane package (Figure 2). Most of the output from the pump sweeps the membrane tangentially and returns to the process tank. The permeate flow is generally less than 10 of the total flow to the membrane. 

To effectively perform complete personnel and equipment decontamination operations, decontamination units use truck-mounted tanks, pumps, and water heater units and trailer-mounted pumps and water heater units. In these processes, reducing the exposure time of the individual or piece of equipment to the chemical contaminant is of the highest priority. 

A similar analysis can be carried out using the same example for the tank, pump, and vessel system (Example 2 in Chapter 1). The BFD for the system is shown in Figure 16.12. 

Belt filter, horizontal vacuum 316 s/s for parts contacting the liquid, including drive and motor but excluding vacuum equipment, platforms, tanks, pumps and piping for feed and wash. FOB cost = 400000 for an effective filter area = 9 m with n = 0.64 for the range 10-60. L-i-M = 2.2-3.2. L/M = 0.42. Alloy factors 316 s/s, X 1.00 rubber-coated, X 1.0 c/s, X 0.60. Complexity factors excluding vacuum auxiliaries, X 1.00 including vacuum auxiliaries, X 1.3. 

Tetrafluoroethylene gaskets are the most suitable for use in storage tanks, pumps, and valves. Stainless steel plug valves or ball valves should have Teflon seats. 

General troubleshooting guidelines are provided for chemical dosage systems including tanks, pumps and tank mixers. Not aU problems may be relevant to a particular system. Problems depend on system design and process conditions. 

Although capital costs of most items in an electrolytic plant are fairly standard, e.g., for tanks, pumps, and separation devices, there are two exceptions the electrolytic reactor itself and the DC power source. Supply of electrical power to the reactor to bring about chemical reaction is also specific to electrolytic processes, and introduces an element into the energy balance which is not otherwise encountered. 

The cost (in US ) of the processing tank, pumps and membranes is calculated using the equations 4,5 and 6, respectively ... 

But let me be completely honest. 1 once had a radiation level detector on a spent sulfuric acid tank. 1 was the operating superintendent at this plant, which regenerated sulfuric add. We had a not-so-small fire at this tank. Rather than repair the tank, pumps, and lines, 1 decided to dismantle and haul away the entire mess of steel. After all, 1 had much larger and more modern storage tanks at my disposal.
