Agitators are one of the most utilised equipments in the Pharmaceutical industry. They ensure proper mixing of various media. With the world looking towards energy-efficient solutions, agitators also needed to be replaced by an API (Active Pharmaceutical Ingredient) company, in order to be energy efficient. Read more about the challenges and solutions in this case study
An API company needed to replace their existing agitators with energy-efficient agitators.
With growing awareness and need for sustainability, companies are moving towards the implementation of energy conservation schemes across their processes
The challenge in this case was that, the company was looking for alternative modifications for the existing agitators to be made energy efficient, instead of a complete replacement of the equipments.
Due to the niche requirement, not a lot of vendors were equipped to work on the existing equipments to make them more energy efficient. GCTPL had the advantage of experience (over other vendors) having done similar projects with their previous customers. The clients thus awarded this project to GCTPL based on the feedback and inputs taken from previous client experiences.
Agitators are one of the most utilised equipments in the Pharmaceutical industry. These ensure the proper mixing of various media. Media includes all liquid types, gases & solids (such as salts, powders, granules etc). Agitator work by rotating an impeller to impart energy to the media, which then interact and mix (they have a shaft and an impeller connected to mixing). The shaft is connected to a motor which drives the mixing mechanism.
The team GCTPL has two challenges to address & overcome:
- Using the client existing agitators
- Avoiding any deviation in the process of mixing due to the upgrades.
The team at GCTPL began analysing each agitator, working on various parameters such as process operating temperature, process liquid, solid content, MOC (Material of Construction) of the tank, impeller and shaft, agitator sweep diameter, bottom clearance etc
Upon completion of the analysis, GCTPL proposed design modifications, followed by certain procurement of equipment ensuring it did not affect the process. GCTPL implemented the recommended actions on the 2 agitators that the clients wanted to pilot test. Post-implementation of modifications & test runs, they observed the process and recorded all parameters for a duration of 30 days.
