Abstract

An understanding of the pulp slurries flow is the important step in the piping system design, piping is a means of transporting pulp in all production lines in the pulp and paper industry. Pulp slurries flow is a complex process flow, this is due to the interactions between the different phases and also due to the turbulent charactheristic of the flow as well. In this study, Computerized Fluid Dynamics (CFD) was utilized to develop a model with parameters obtained from the pulp slurry flow in the field to characterized pressure drop and velocity profile in the medium consitency pulp of 10%. CFD modeling uses Ansys Fluent with the Mixture method and the SIMPLE solver algorithm. The fully developed flow is at elevation of Y = 4.85 m and at direction of Z = -2.55 m and it is turbulent flow characteristics. The pressure drop along the pipe is 68401.2 Pascal.

Abstract

The current problem in the Palm oil industry is POME's final discharge failed to comply with discharge standards. This study aims to treat POME final discharge using magnetic biochars (MBC) and treated water can be reused as raw water for the palm oil industry. MBC were successfully produced from palm fronds through the pyrolysis process together with FeCl3.6H2O modification. MBC were characterized by acquiring elemental, functional groups, morphological and magnetic properties of adsorbent. The characterization showed embedded iron oxide crystals within the biochar structure with a magnetic strength of 12,14 emu/g which can assist the separation process of the powdered adsorbent from the treated water. The highest removal of COD, TSS, and color was 72.72%, 77.95%, and 84.30%, respectively with an 8.55 g/l magnetic biochar dosage and 150 minutes contact time. However, the results of the final POME effluent treatment have not all of the parameters reached the industrial water quality standard class 3.

Abstract

Electronic textiles (e-textiles) are generally made by coating fabrics with conductive particles to impart conductive and electromagnetic properties to textile fibers and filaments. E-textile can be made by several methods, such as "dip and dry", pad-dry, screen-printing, or injeksi printing. Lyocell is the latest generation of cellulose fibers that are used as textile raw materials. Lyocell has naturally hyperhydrophilic properties and greater moisture absorption. Then, graphene is a nanomaterial composed of carbon atoms with a hexagonal structure, it has a very high conductivity value, reaching 104 S/cm. Graphene can be produced in several forms, such as very few layer graphene (VFLG). This paper aims to improve understanding of the research and review of electronic textiles created by combining lyocell textile with very few layer graphene (VFLG). This composition can enable the formation of sustainable electronic textile composites.

Abstract

Oil is the energy source that people demand and use the most right now. Recent years have seen a lot of interest in polymer flooding as a cutting-edge chemical-based enhanced oil recovery (EOR) solution. Field X Minyak Cekungan Sumatera is acceptable for chemical EOR (Polymer) testing with a success range of up to 70%. The polymer solution will follow the channel that the water has created, and because of its high viscosity, it tends to "block" this area of the reservoir, allowing previously immobilized oil to start flowing. This can improve sweep efficiency. In this study, four polymers will undertake screening tests on the basis of compatibility, concentration, viscosity vs. shear rate, filtration, screen factor, and thermal stability. The best results is polymer 2 after polymer screening included passing the compatibility test, producing the best viscosity compared to the other three polymers at the same concentration, FR 1.2, having the best screen factor value compared to the other three polymers, and passing the thermal stability test.

Abstract

Deep eutectic solvents (DES) were intoduced to overcome the drawbacks of conventional catalysts (H2SO4, HCl, H3PO4, p-toluene sulfonic acid) due to several advantages; biodegradibility, cheap raw materials, high thermal and chemical stabilities, low melting point, low volatility, low toxicity, simple preparation as well as its physicochemical properties (melting point, acidity, density, viscosity, solubility and polarity) are easy to modify. DES is a mixture of two or more compounds of hydrogen bonding acceptor (HBA) and hydrogen bonding donor (HBD). The hydrogen bond formed between HBA/HBD mixture resulting to lower lattice energy thus lowering its melting point. Previous authors had reported the application of DES as reaction medium exhibit excellent catalytic activity on product yields, conversions and reusabilities. The aim of this article is to attract attention more comphrehensive studies on the utilization of DES as potential green catalyst.
