Blocked discharge

Check the discharge block valve opening first. It may be partially closed and thus the problem.

Close the pump suction and discharge block valves. 

It is for this reason that we frequently find a value for the specific capacity of organic lithium-oxygen batteries which is standardized in relation to the carbon electrode the mass of carbon is used in calculating the specific capacity because the products of reduction during discharge block the available pores. The reduction products can be dissociated reversibly to re-form the initial reactants (oxygen and lithium ions). 

For axial flow pumps, required horsepower decreases with inaeasing flow rate wifo the maximum horsepower required at shutoff condition. Motors foe axial flow pumps are not selected to handle low Bows. During startup, discharge block valve at axial pump discihaige line should be opened to prevent high horsepower requirement at low flow startup condition. 

The scraper or knife discharge consists of a blade that removes the cake from the dmm by direct contact with the filter cake. It is normally used for granular materials with cake thickness greater than about 6 mm. In order not to damage the filter cloth, a safety distance of 1 to 3 mm between the blade and the cloth must be observed. If the residual layer is made not of filter aid but of the product, there is danger of its blocking by fine particles and by successive consoHdation by the scraper blade. 

Dead legs in the sample line must be discharged safely to ensure that the sample will ac tuaUy be representative of the material in the unit. Without blowing down the dead leg, samples taken will be erroneous, as they may be representative of some past operating conditions. If the location is nonroutine, the sample leg may have accumulated debris. The debris could partially or totally block the line. Opening the isolation valve to blow down the line could result in a sudden, uncontrolled release, presenting a hazard to the sample gatherer. 

The tube is much longer than needed for the catalyst volume to provide a surface for preheating and to minimize temperature losses at the discharge end. The tube can be bent into a U shape and immersed in a fluidized sand bath, or it can be straight and placed inside a tubular furnace in a temperature-equalizing bronze block. Thermocouples are usually inserted... 

Place the measuring tube on the top of the basket holding with one hand. Be careful not to block the discharge flow at the open top of the reactor. 

On line 6.1.1, report the amount of the listed chemical transferred to a POTW listed in Part II, Section 1. In the block provided, enterthe numberfrom Part II, Section 1 corresponding to the POTW to which the discharge is sent. For example, if the discharge is sent to the location listed in Part II, Section 1.1, then enter 1 in the block provided (the first digit of this... 

In offsite locations, thermal expansion PR valves may discharge to a flare header upstream of a knockout drum, if available, or to the equipment (e.g., a tank) on the opposite side of one of the blocking-in valves, or to the atmosphere. Atmospheric discharges must be at grade level in a safe location...
