Chemical & Petrochemical Two Bed Deionizer (DI) Guide

The calculations above can be used as a guide for ultrapure chemical and petrochemical separate bed deionizer system sizing. Steel, FRP or stainless steel (304, 316, 316L) can be used for crucial petrochemical and chemical water treatment processes. Industrial DI water systems are ideal for any application with need for TDS (conductivity) reduction where reverse osmosis isn’t a good application due to water chemistry (e.g. low TDS or small particle TSS). Chemical and petrochemical two bed demineralization systems are also ideal for power generation, oil and gas, pharma, critical boiler water pre-treatment and many other high purity and UPW applications. Other calculators for specialized industrial, ultrapure DI systems can be found here:

There are several variables when sizing ultrapure twin bed demineralizers (DI) water systems that are beyond the scope of the guide and calculator below. Water pressure, water chemistry, and system feed flow rate are all variables that have effects on demineralizer (industrial deionizer) sizing and are not considered. These calculators are used for quickly estimating footprints, size & general design of ultrapure water deionization systems in the petrochemical and chemical industries.

For a more detailed analysis and sizing of chemical and petrochemical DI systems, including configurations (e.g. single, twin, triple or special multiple tank configurations), control types (Allen Bradley, GE, Siemens PLC, additive or progressive flow) or specifications like (316, 316L, 304) stainless steel, Hastelloy or specific valve & instrument types, it is important that you email or call Nancrede Engineering at 888-56-WATER (569-2837).
