The mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. A gas-induced External Airlift Loop Bioreactor (EALB), a forced-liquid Vertical Tubular Loop Bioreactor (VTLB) and a forced-liquid Horizontal Tubular Loop Bioreactor (HTLB) were used for mixing studies as well as biomass production from natural gas. The effect of design parameters, riser to downcomer cro...

A compact separator consisting of two volutes (inlet and outlet) connected with a cylindrical chamber is proposed as a cost-effective alternative to conventional separators. The separator has a wide range of applications in the oil and gas industry. It has the advantages of being compact, free of the effect of motion on floating platforms, more tolerant to flow fluctuations and can be modularis...

Reaction of Cr(CO)(6) with trimesic acid in DMF affords the metal-organic framework Cr(3)(BTC)(2).nDMF (BTC(3-) = 1,3,5-benzenetricarboxylate), which is isostructural to Cu(3)(BTC)(2).3H(2)O. Exchanging DMF for methanol and heating at 160 degrees C under dynamic vacuum for 48 h results in the desolvated framework Cr(3)(BTC)(2). Nitrogen gas adsorption measurements performed at 77 K revealed a t...

This project is based on LabVIEW software using NI-myRIO and it is meant for low cost, small size and light weight unmanned ground vehicle .It is specialized in wheel structure and camera courage .the typical wheel design is used to cross the obstacles present in the path of vehicle and the camera is rotated with respect to the wheel direction .the camera provides image of the place. The gas se...

Metal organic frameworks (MOFs) are a wide class of crystalline porous polymers studied in many fields, ranging from catalysis to gas storage. In the past few years, MOFs have been studied for the encapsulation of organic or organometallic molecules and for the development of potential drug carriers. Here, we report on the study of two structurally-related mesoporous Cu-MOFs, namely PCN-6 and P...
