Consequently, water glycol can be a tough challenge for piston pumps—the case in point for the competitive pumps originally specified by Gerdau Ameristeel. "The bearings in the pumps are small, making it difficult for them to withstand the load and effects of the reduced film strength of the water glycol-based fluid," says Rod Pizzey ...
China's soybean crushers have been struggling with negative margins since June and the recent power restrictions could help elevate the margins a bit. China's gross crush margin improved by $10.42/mt on week to minus $7.52/mt, while prices for imported soybeans to China dropped by 1.4% on the week to $623.82/mt, according to S&P Global Platts ...
The concentrated crude glycol solution leaving the final evaporation effect is stripped of its remaining water and light impurities in the light ends column. The water free glycol mixture is then distilled in a series of vacuum towers to produce fiber grade MEG and high purity higher derivatives. The final column produces a small bottoms

Crude glycerol is the by product produced throughout the biodiesel production process. However glycerol produced at this stage is crude glycerol which is about 80% pure and contains other contaminants like methanol, water, salt and soap. Crude glycerol has approximately about 45% glycerol, 10-15% water and methanol, 10-15% salt, and 30% soaps …
6 Flow-sheeting (special language conveying information) Process design normally starts with a process scheme (flowsheet). The flowsheet is the key document or road map in process design.
of $9.78 million. Under the assumptions that the prices of crude glycerol, hydrogen, and propylene glycol are $0.22, $0.50, and $1.00 per pound respectively, the net present value (NPV) at the end of the 15 year allotted course of the project is $88.4 million and the investors' rate of return (IRR) is 58.45%.
Linear-bottlebrush, amphiphilic copolymers were grafted from the surface of silica (SiO2) nanoparticles to form "nanoparticle micelles" that, regardless of the concentration, possess the capability to encapsulate and stabilize non-polar structures in aqueous media. These nanoparticles afford high water dispe
Mining processing.

The tables below list results of published tests of autoignition temperatures under conditions likely to be found in vehicle environments. The tables show a wide variation in the measured temperatures. For example, different researchers have found DOT 3 brake fluid ignites on hot metal at temperatures ranging from 520 to 752 degrees F (Table 2 ...
At present, ethylene glycol produced by some plants still has low UV transmittance rendering it unsuitable for use in polyester production. In this paper, a method was developed for the identification of the impurities that cause commercial ethylene glycol to have low UV transmittance, using solid-phase extraction (SPE) and some analytical ...
Many products derived from crude-oil refining, such as ethylene, propylene and butadiene, are olefinic hydrocarbons derived from refinery cracking processes, and are intended for use in the petrochemical industry as feedstocks for the production of plastics, ammonia, synthetic rubber, glycol and so on.
The invention discloses a method for purifying a crude sodium formate byproduct from neopentyl glycol production. The method comprises the following steps: (1) dissolving secondarily-distilled residue from neopentyl glycol production in water to obtain a crude sodium formate solution; (2) adding calcium formate, and precipitating to remove oxalate and …

Crude glycerol generated from biodiesel production is impure and of little economic value. In general, glycerol makes up 65% to 85% (w/w) of the crude stream (Gonzalez-Pajuelo et al. 2005; Mu et al. 2006). The wide range of purity values can be attributed to different glycerol purification methods or different feedstocks used by biodiesel ...
