Case Study: Blendtech Cuts the Cost of API 2350 Compliance

View in HTML

When the American Petroleum Institute (API) introduced updates to API Standard 2350, “Overfill Protection for Storage Tanks in Petroleum Facilities,” Blendtech's customer needed help to comply. The updated standard significantly changed the way that tank receipts are handled, requiring formal processes for reconciling receipts and distributions. At the time, the customer used a labor-intensive verification process. To comply, they would either have to hire more personnel or expand infrastructure, costing hundreds of thousands of dollars. 

Blendtech’s task was to find a way of automating this costly process. Read the case study and see how the company created a cost-effective automated reconciliation system that improves both safety and accounting.

Edge Computing in Industrial Automation

Successful industrial internet of things (IIoT) applications send data from systems that monitor and control the physical world to information technology (IT) data processing systems. There the data can be analyzed and the results used to improve business capabilities: better inventory management, better predictive maintenance, reduced asset downtime, and much more.

But to achieve these IIoT goals, we need to solve 3 problems: how to connect the physical world to the IT world, how to handle the huge masses of data that physical systems produce, and how to efficiently structure the IIoT.

This white paper explores these problems and how edge computing and architectural change can help solve them.
