Description: Fertilizer plants commonly use steam turbines to drive process air compressors, synthesis gas compressors, refrigerant compressors, electric generators and other mechanical devices. The cost of producing steam to operate the plant's turbines is significant. Any adjustments in operation that can improve turbine performance will lead to reduced energy consumption and cost. Unfortunately, the equipment that is used to support the turbine is often overlooked. This article will explore the important relationship between operation of the steam surface condenser and its venting ejectors, and how their performance directly affects the fuel costs associated with operating a steam turbine.

Description: Steam Surface Condensers are critical equipment in a fertilizer plant, and can directly impact plant throughput and product quality. This article reviews key design decisions that affect capital cost and outlines operating variables that can negatively impact performance reliability.
Description: Sizing of steam surface condensers based on turbine steam flow which includes steam inlet velocity, cooling water flow and pressure drop, air leakage for design, fouling factors to use, ASME, HEI, and TEMA design codes, gas removal system design and space limitations for the condenser size.
