Sizing Pumps with Monte Carlo Methodology

When it comes to pumping systems that have varying demands, many engineers are hesitant to size the pump to less than the highest possible load. While this is certainly conservative from a flow standpoint, the downside is that additional costs are incurred to mitigate what might be a small risk. To assess that risk and make an informed decision, take a Monte Carlo approach, which can save considerable money.

How a Piping System Model Can Be Used in a PSM Plan

There are 13 areas included in a process safety management (PSM) plan. The piping system model can be of value in all aspects of the PSM, but the areas of greatest impact are in: process safety information process hazard analysis operating procedures and practices employee training pre-startup safety managing change investigation of incidents Process Safety Information

Developing a Model for Process Safety Management

Working with chemicals can pose a host of dangers. Those in the process industries must take every step possible to protect employees and others from hazardous conditions. The U.S. Occupational Safety and Health Administration (OSHA) issues and enforces standards designed to increase worker safety, including for facilities that process chemicals. Other countries have similar programs, and the United Nations oversees the Globally Harmonized System for Hazard Communication in an effort to protect workers internationally. One mandated OSHA standard is the Process Safety Management (PSM) of Highly Hazardous Chemicals (standard, 29 CFR1910.119) to prevent the unwanted release of hazardous chemicals that could cause serious exposure.

Types of Flow Meters

Knowing the flow rate within a fluid piping system is one of the most useful measurements in understanding system operations. The equipment used to measure flow rates is typically maintained and calibrated by the plant instrumentation and control groups. Facility flow meters typically monitor custody transfer or are used as the primary elements of flow control circuit.

Proper Pump Selection: Avoid Oversizing Your Pumps

Proper pump selection is more important than ever, with drastic consequences on maintenance, reliability, and efficiency. The selection process remains difficult for average users, and even contracting the work out to a reputable engineering firm does not guarantee success. In this article, we will cover centrifugal pump design, common pitfalls in the selection process, and consequences of improper selection.
