Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize the power-generation capabilities of steam networks. This article presents a spreadsheet-based optimization model...

Pilot plant operation has been completed for a process that produces the fertilizer potassium sulfate from the mineral polyhalite, a hydrated sulfate of potassium, magnesium and calcium. The process, developed by Intercontinental Potash Corp. (ICP; Golden, Colo.;, resurrects a route to K2SO4 that was first explored in a push to develop a domestic source of potash after a German embargo in...

Sapphire Energy, Inc. (San Diego, Calif.; and The Linde Group (Munich; have signed an agreement, with a minimum span of five years, to commercialize Sapphire’s process for producing crude oil from algae. The agreement expands an existing partnership in which the two companies have developed a low-cost method for delivering CO2 to algae ponds. Linde will now help...

A typical fluid catalytic cracking unit (FCC) generates about 200 tons/d of dry gas — a mixture of off-gases that is burned as refinery fuel. However, about 40 tons of that gas is ethylene, which would have much greater value as gasoline or diesel fuel. A process that converts better than 40% of the ethylene to motor fuels in a single pass is being developed by UOP LLC, a Honeywell...

China’s largest private chemical EPC (engineering, procurement, construction) contractor, Wison Engineering Ltd. (Wison; Shanghai; has recently introduced details about its proprietary butadiene technology, which is set for commercialization. The process aims to meet the anticipated growth in annual butadiene consumption, which will “far exceed” global expansion in...

Naomi Shibasaki-Kitagawa at Tohoku University (Sendai, Japan; has developed a continuous reactor for making biodiesel fuel from low-quality waste, such as cooking oil. Her production process uses an expanded-bed reactor packed with an anion-exchange resin that has both catalytic and adsorption capabilities. The...

Conventional methanation — the reaction of CO and H2 (synthesis gas) to form methane — has recently become important as a way to produce substitute natural gas (SNG) from gasified coal in regions of the world where natural gas is scarce (see Chem. Eng., August 2010, pp. 14–17). Now, an alternative methanation process, which produces CH4 directly from CO2 and H2, has been developed by...
