Abstract:

Fuel gas compressors installed in cogeneration systems must be highly reliable and efficient machines. The screw compressor can usually be designed to meet most of the gas flow rates and pressure conditions generally required for such installations. To an ever-increasing degree, alternative sources are being found for the fuel gas supply, such as coke-oven gas, blast-furnace gas, flare gas, landfill gas, and synthesis gas from coal gasification or from pyrolysis. A feature of the oil-free screw compressor when such gases are being considered is the isolation of the gas compression space from t

Abstract:

Centrifugal compressors are widely used to compressor gas in many different processes within the petroleum and chemical industry. Two vibration types of concern in industrial compressors are synchronous and subsynchronous vibration. The latter, more troubling type of vibration, occurs when non-conservative whirling forces(Cross-coupling) act to excite a lateral natural frequency, which lies below the running speed(subsynchronous vibration). In this paper, more attention is paid to impellers from a rotordynamic standpoint and a synthesis gas compress in ammonia plant is analyzed in order to dia

The gas-dynamic stability of compressors of aircraft gas turbine engines is one of the most important conditions that determine their reliability and level of flight safety. Unstable operation of the compressor in the engine system (surge) leads to loss of thrust accompanied by an increase in gas temperature in front of the turbine and increased vibration because of large amplitudes of pressure pulsations and mass flow through the engine path.

Abstract:

Abstract A numerical study of the planar gas expansion under pulsed evaporation into the background gas is carried out. The chosen conditions are typical for nanosecond laser deposition of thin films and nanostructure synthesis, with the saturated gas pressure at the surface of 5.4 MPa and the background pressure of 50 and 500 Pa. The problem is solved based on the direct simulation Monte Carlo method and direct numerical solution of the BGK model kinetic equation. A generally good agreement was obtained for all computed macroscopic quantities, with the exception of the higher density peak in

Abstract:

The primary driver of operating costs in natural gas processes is the energy consumption of the compression system. Multistage compression configurations are commonly employed and hence play a vital role in optimization of natural gas processes. In this study, a generalized disjunctive programming model for multistage compression is formulated. The model is useful for both synthesis and optimization of multistage compression configurations. By using this approach, we further seek improvements in shaft work savings. The model relies on thermodynamic equations and is designed to minimize the con

Abstract:

1. Introduction The Pt catalyst supported on carbon black (Pt/CB) is widely used as a catalyst for the polymer electrolyte fuel cell (PEFC). As an alternative carbon support to the CB, we have used Marimo-like carbon (MC). MC has a spherical structure comprised of carbon nanofilaments (CNFs) radially grown from an oxidized diamond core 1). There are voids of several hundred nanometers between the CNFs of the MC. These voids are expected to improve the mass diffusivity. The cell components of the PEFC mainly include the catalyst layer (CL), gas diffusion layer (GDL), flow field plates, and gask

Rising greenhouse gas emissions, particularly CO2, present significant environmental challenges. The goal of this study is to improve methanol synthesis using CO2 hydrogenation, with an emphasis on increasing purity. To accurately restrict temperature rises during CO2 compression, we did simulations with Aspen HYSYS V11 and a multistage compression approach. Two notable alterations included the insertion of an absorber unit to improve methanol purity and the recycling of separator outputs. The results show that these process innovations save energy and raw resources while significantly improvi

Zinc oxide (ZnO) nanomaterials were efficiently synthesized using a microwave plasma torch system at atmospheric pressure. The Zn powder was passed through a microwave plasma region, in which it melted and vaporized. Tetrapod-type ZnO nanomaterials with a diameter of 29.8 ± 8.0 nm were synthesized using a high-purity O2/N2 mixed gas. In particular, ZnO nanowires with a diameter of 109.5 ± 8.0 nm and a length of 5–6 μm were produced using an inexpensive compressed air as a microwave plasma gas. It was confirmed that the nanowires synthesized using the compressed air showed higher light absorpti

Vehicles that use natural gas exhibit lower costs and emissions, when compared to the gasoline-fuelled vehicle. The present challenge of natural gas is how to improve its energy density. This research solves the problem of energy density by studying the natural gas storage technologies with improved adsorbent. Comparisons between the two storage systems, thus; with adsorbent and with conventional method are made technically based on associated amount of moles. We also compare gas storage in different cylinder types (Kusmiyati et al., 2004, Wei et al., 2015 and Torregrosa et al., 2013) based on

As one of the main raw materials in the fertilizer industry, global ammonia consumption continued to increase from 2010 to 2020, at a rate of about 1.81% per year. The ammonia production process is divided into four main stages: Feed Gas Pre-Treatment, Syngas Generation, Syngas Purification, and Ammonia Synthesis. The raw materials required for the ammonia production process include natural gas, steam, and air. To meet the increasing demand for ammonia, a production process with high efficiency is required in order to produce high conversion. One of the efforts to increase efficiency is throug

The biomass-to-methanol process may play an important role in introducing renewables in the industry chain for chemical and fuel production. Gasification is a thermochemical process to produce syngas from biomass, but additional steps are requested to obtain a syngas composition suitable for methanol synthesis. The aim of this work is to perform a computer-aided process simulation to produce methanol starting from a syngas produced by oxygen–steam biomass gasification, whose details are reported in the literature. Syngas from biomass gasification was compressed to 80 bar, which may be consider
