Abstract

Methods, systems, and apparatuses for monitoring health of a catalyst in a plant by retrieving plant data, comparing the plant data to equilibrium conditions, and sending a notification comprising an indication of the health of the catalyst. A plant may be configured to produce a product using a catalyst. A plant monitoring computing platform may be configured to receive, from sensors and/or computing devices of the plant, plant data and/or lab data corresponding to the catalyst. The plant monitoring computing platform may determine equilibrium conditions corresponding to the plant. Based on a comparison of the plant data, the equilibrium conditions, and/or target equilibrium conditions, the plant monitoring computing platform may send a notification. The notification may comprise an indication of the performance of the catalyst.

comparing the plant data to the equilibrium conditions, wherein comparing the plant data to the equilibrium conditions comprises comparing the measurement to the target operating conditions associated with the catalyst;
determining, based on comparing the equilibrium conditions to the plant data, a notification; and
transmitting, by the computing device, the notification.

2. The method of claim 1 , wherein the measurement corresponds to an inlet of the plant, and wherein the inlet is configured to introduce the catalyst to the reactant.

3. The method of claim 1 , wherein the notification comprises an indication comparing a first active portion of the catalyst at a first time to a second active portion of the catalyst at a second time.

4. The method of claim 1 , further comprising:
receiving, from the sensor, initial plant data, wherein the equilibrium conditions are based on the initial plant data.

5. The method of claim 4 , further comprising:
determining a first portion of the initial plant data corresponding to a time period when the catalyst is stabilizing;
