Abstract
An apparatus for advanced crystallization testing (ACT) for pipeline applications is provided. The apparatus includes: a reaction vessel including an open end and a closed end; a removable cap to hermetically seal the open end, the removable cap including a transparent window made of a transparent solid material; a Raman probe facing toward the transparent window and being configured to collect a Raman signal from inside the reaction vessel through the transparent window; an agitation mechanism to agitate contents of the reaction vessel; a bath to house the reaction vessel and maintain a temperature of the reaction vessel at a set temperature.

An apparatus comprising:
- a reaction vessel comprising an open end and a closed end;
- a removable cap to hermetically seal the open end, the removable cap comprising a transparent window made of a transparent solid material;
- a Raman probe facing toward the transparent window and being configured to collect a Raman signal from inside the reaction vessel through the transparent window;
- an agitation mechanism to agitate contents of the reaction vessel;
- a bath to house the reaction vessel and maintain a temperature of the reaction vessel at a set temperature.
A system of Raman spectroscopy comprising:
- a plurality of batch reactors, each batch reactor comprising
- a reaction vessel,
- a sealable inlet port attached to the reaction vessel,
- a removable cap to hermetically seal the reaction vessel, the removable cap comprising a transparent window made of a transparent solid material, and
- an agitation mechanism configured to agitate contents of the reaction vessel;
- a Raman probe connected to a Raman detector and a laser source;
- a probe adjusting mechanism configured to move the Raman probe or the plurality of batch reactors such that the Raman probe is faced toward any one of the plurality of batch reactors;
- and
- a bath to house the plurality of batch reactors and maintain a uniform temperature of the plurality of batch reactors at a set temperature.
A method of processing, the method comprising:
- loading a plurality of batch reactors with a crystal precursor, a solvent, wherein each batch reactor comprising,
- a reaction vessel having a cylindrical shape,
- a removable cap to hermetically seal the reaction vessel, the removable cap comprising a transparent window made of a transparent solid material;
- hermetically sealing the plurality of batch reactors with the removable cap;
- immersing the plurality of batch reactors into a bath configured to maintain a set temperature;
- and
- measuring Raman signals using a Raman probe from inside one of the plurality of batch reactors through the transparent window, the Raman signals being characteristic of a crystallization process within the one of the plurality of batch reactors.
