Non-disruptive sampler for fluid processing apparatus
A sampling module of a fluid processing apparatus includes at least one multi-configuration device connected to a filtration module. The invention relates to an area of non-disruptive sampling from any flow stream including the ones containing solids. The fluid processing apparatus remains in fluid communication with a sample processing module in all configurations of the sampling module and the parameters deemed critical for a chemical process remain unaffected during the sampling event. The entire event is controlled from a computer and the results are collected to make decisions on analytical and process controls.
1. A method for analyzing fluids comprising:
a) configuring a fluid diverting device to receive at least a portion of a fluid stream from a reactor module to a filtration module equipped with an inline filter;
b) flowing at least a portion of the fluid from the reactor module through the filtration module;
c) flowing at least a portion of the fluid downstream of the inline filter to a fluid holding device;
d) configuring the fluid diverting device to establish a fluid communication between the fluid holding device and a sample delivery module;
e) flowing at least a portion of the fluid from the fluid holding device to the sample delivery module;
f) flowing at least a portion of the fluid upstream of the inline filter of the filtration module to the sample delivery module;
g) configuring the fluid diverting device to adopt more than two configurations wherein flowpaths on the configurable portion of the fluid diverting device are configured in such a manner so that any two consecutive configurations of the fluid diverting device do not have the same configurable flowpaths receiving fluid from the reactor module; and
h) flowing at least a portion of the fluid from the sample delivery module to a sample analysis module for analysis.
2. The method of claim 1 , wherein a flowpath of the configurable portion of the fluid diverting device, which was receiving fluid from the reactor module in a specific configuration, is moved to a new position so a fluid moving device can move a secondary fluid stream through the same flowpath in the next configuration.
3. The method of claim 2 , wherein the secondary fluid stream is a fluid capable of removing solids from the flowpath of the configurable portion of the fluid diverting device.
4. The method of claim 1 , wherein steps a), b), c), f), and g) are repeated more than one time prior to a one-time execution of step d), e), and h).
5. The method of claim 1 , wherein the fluid diverting device stays in a specific configuration until the inline filter is saturated with solids.
6. The method of claim 2 , wherein the configurable portion of the fluid diverting device is configured by moving the configurable portion clock-wise or counter-clockwise.
7. A method for analyzing fluids comprising:
a) flowing at least a portion of a fluid stream from a reactor module to at least one (the first) of two inline filters (a first and a second) of a filtration module;
b) flowing at least a portion of the fluid upstream of the second inline filter to a sample delivery module;
c) configuring the filtration module so the fluid from the reactor module flows through the second inline filter;
d) flowing at least a portion of the fluid upstream of the first inline filter to the sample delivery module;
e) configuring the filtration module to adopt more than two configurations wherein flowpaths of the configurable portion of the filtration module are moved in such a manner so that any two consecutive configurations of the filtration module do not have the same configurable flowpaths receiving fluid from the reactor module;
f) flowing the filtrate downstream from the first or the second inline filter to the sample delivery module; and
g) flowing the filtrate from the sample delivery module to a sample analysis module for analysis.
8. The method of claim 7 , wherein a flowpath of the configurable portion of the filtration module, which was receiving fluid from the reactor module in a specific configuration, is moved to a new position so a fluid moving device can move a secondary fluid stream through the same flowpath in the next configuration.
9. The method of claim 8 , wherein the secondary fluid stream is a fluid capable of removing solids from the flowpaths of the configurable portion of the filtration module.
10. The method of claim 7 , wherein the filtration module stays in a specific configuration until the inline filters are saturated with solids.
11. The method of claim 7 , wherein the configurable portion of the filtration module is configured by moving the configurable portion clock-wise or counter-clockwise.
