Acid pumping

Storage areas for maintenance, janitorial, and other service organizations must be provided. Safety items such as fire extinguishers, firehose cabinets, safety hoops on permanent ladders, guard rads, shielding for acid pumps, clearance for electric panel boards, etc, are needed. Manholes and cleanouts for sewer pipes within the facility as well as in the landscape and parking areas should be provided. [Pg.441]

Proton Pump Inhibitors and Acid Pump Antagonists. Figure 2 Chemical mechanism of irreversible PPIs. PPIs are accumulated in acidic lumen and converted to active sulfenic acid and/or sulfenamide by acid catalysis. These active forms bind to extracytoplasmic cysteines of the gastric H.K-ATPase [3].

By virtue of their construction, diaphragm pumps cannot be used for high pressure applications. In the Mars pump, there is no need for a diaphragm as the working fluid (oil), of lower density than the liquid to be pumped, forms an interface with it in a vertical chamber. The pump, which is used extensively for concentrated slurries, is really a development of the old Ferrari s acid pump which was designed for corrosive liquids. [Pg.319]

The injection point of the sulfuric acid is in the pump bay, or as near as possible to water intake. The sulfuric acid pump is normally a motor-driven proportioning pump, and an electric motor is connected to a pH analyzer installed on the cooling water supply header so that the pump starts and stops, depending on the pH in the circulating water. Table 8.2 summarizes various chemical treating agents for cooling water towers. [Pg.197]

The medium in the fermentor was inoculated with 1% (v/v) inoculum, and feeding was started when the glucose in the medium was completely consumed with a rise in pH since the medium s pH increased as a result of glucose depletion and the use of organic acid as the carbon source. When the pH rose, the base pump was turned off and the fed rate of the fed medium was controlled by an acid pump. When the glucose feed in, the... [Pg.364]

The primary system is intended to isolate the major equipment in order to prevent reverse flow and exhaust oxides in a gaseous state. It consists of a special restraint type valve (check) and two motorised shutdown valves, arranged in series. The system includes a low pressure detector on the main pipe that trips the sulphuric acid pumps, isolates the process and stops the helium flow into the reactor and heaters (emergency system EAS-200).

Fig. 9.2. Acid pump, courtesy Lewis Pumps www.lewispumps.com A submerged impeller (right) draws acid in through the bottom mouth and pumps it up the up-leg (left). A pipe extension is bolted to the top of the up-leg to get the acid to its destination. The motor and motor-shaft connection are well above the acid. Details ...
