An automated spreadsheet method can quickly help minimize fresh hydrogen consumption while maximizing hydrogen recovery and reuse in petroleum refineries and petrochemical complexes In petroleum refineries and petrochemical complexes, there are many hydrogen consumers, such as hydrotreaters, hydrocrackers, isomerization units…
One of the earliest applications for zirconium in the chemical process industries (CPI) is for sulfuric acid service. Used commonly during the manufacture of chemicals as a catalyst, dehydrating agent, absorbent, or an oxidizing or reducing agent, sulfuric acid is…
Accurate temperature measurement is not difficult. It does, however, require you to think about accuracy from specification and selection, all the way up to installation and operation of your temperature-measurement sensor. There are opportunities to improve accuracy during each of…
FIGURE 1. In a typical system for wastewater treatment, the liquid feed is introduced at the top of the column and steam is introduced at the bottom In recent years, steam strippers have become integral parts of industrial plant…
Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks. Horizontal, carbon-steel ASME-type tanks of 10,000 — 40,000 gal capacity should have a plate thickness of…
Effective use of capital in the ownership and management of manufacturing assets is critical to the financial performance of companies in the chemical process industries (CPI). Many of these companies use benchmarking in compliance with applicable laws and antitrust…
