15 Module 2: System Overview

16 System Overview The Mega MB321-LCU Mobile Blending System, Model 100 is an automated chemical blend/distribution unit which dynamically blends chemical from up to two carboys with DI water from a house supply line. This in-line blending system is used to maintain specified levels in the distribution tank. An automated filter system filters chemical before it is supplied to the global loop. This filter system is capable of automatic swapping of filter banks due to high differential pressure, as well as auto flush/purging before filter element removal. System Overview

Dynamic Blending LFC W01E DI Water Supply LFC AV Q02 AV D03 AV W01E Sequence of Operations AV W02E Calibration Port Process Drain Static Mixer #1 Static Mixer #2 AV D02A AV D02B Tank If the carboy runs empty, the chemical feed loop will auto swap to the standby loop and signal the operator to replace the empty carboy. When blend is requested, the addition line is opened during blending and returns to the recirculation state when finished. Chemical is continually recirculated back to the carboy in order to maintain steady flow through the metering pump until a blend is requested. Chemical and DI water meet in the blend plenum before flowing through two static mixers and on to the Distribution tank. The raw chemical feed system consists of two chemical feed loops, each containing a raw chemical carboy, a high accuracy metering pump, a recirculation line, and blend addition line. The metering pumps draw chemical from the carboy and dispense at a steady flow rate, while the flow controller allows DI water to be added determined by the current recipe. The blend function is triggered by a tank low-level state set by the level sensor or the tank scale. Blending continues until the tank high-level setting is reached. One loop acts as the primary blend addition line, while the other is in standby.

If a pump fails or a swap timer occurs, the active pump swaps to the standby pump. Global loop pressure and flow is controlled by a combination of a supply flow meter, pump feedback, and a manual back-pressure regulator on the global loop return. After the batch has been qualified, material is pumped to the global loop. Once blended chemical has filled the tank to the required minimum level, the contents can be recirculated locally for a given period and metrology is used to qualify the batch.

Material dispensed from the main system is pumped through a single filter on a single bank prior to reaching the global loop. The filter switching function brings the standby filter bank on line and fills it with material to bring the online filter bank offline for servicing. Pressure transducers monitor pressure across the filters. If a pressure drop exceeds the filter change-out setpoint, the filter bank switching function is initiated. The distribution filter subsystem is a dual filter, dual bank filtration process that provides single-staged filtration to the global loop, with a redundant bank as backup. At a set time to ensure evacuation of all nitrogen from the lines, the standby filter bank discharge isolation valve is opened and the offline filter bank is isolated from the discharge path. Next, drain valves are opened and the inlet isolation valve to the bank opens to fill the void spaces in the filter bank with material, and push out the purge nitrogen.

47 Alarm Types Alarms are activated when a system interlock is tripped.
CRITICAL alarms are activated by urgent situations that require immediate attention and threaten the performance of the system. A critical alarm sounds the audible annunciator and shuts down the system. A chemical system shutdown (CSS) critical alarm stops the distribution pumping. Alarm Types PROCESS alarms are activated by situations that require immediate attention, but do not threaten the performance of the system. An audible annunciator is sounded and the sequence of actions are paused. Process Alarms shut down the affected station. WARNING are activated by those situations that do not need immediate attention, but could escalate into a more serious problem if ignored.

48 Responding to Alarms The alarms have three states: active, acknowledged, and reset. An active alarm indicates the interlock is currently tripped but has not been acknowledged. The audible annunciator sounds when active alarms exist. Responding to Alarms When an operator presses the Acknowledge key, the audible annunciator turns off and the alarm is lowered to the acknowledged state. When the operator presses the Reset key, the alarm is reset. If the condition which caused the interlock has not been corrected, the alarm is reactivated.

Pressure Transducer Component Description Measuring line pressure allows for obtaining valuable and critical diagnostic information, which is used for monitoring or controlling process conditions such as DI water and chemical dispense. Pressure Transducer

54 Component Description, continued
Regulators Flow Regulator Flow regulators consist of a solid float inside a tapered vertical tube that widens at the top. Fluid enters at the base of the tube, causing the float to rise. The upward or downward movement of the float corresponds to the rate of fluid flow in the tube. A rotameter consists of a tapered tube with a float inside that is pushed up by flow and pulled down by gravity. At a higher flow rate the float rises. The float is shaped so it rotates axially as the fluid passes. Rotameter Component Description Reducing Regulators Reducing regulators control the incoming pressure to an exact pressure no matter what happens to the incoming pressure. The regulator design is based on a diaphragm and needle through a hole principle. The diaphragm moves to compensate for any changes in incoming N2 pressure.
