Effect of Pressure and Temperature on the Retention Time of Crude Oil Inside the Three-Phase Separator Using the Response Surface Methodology

|
By José Cláudio Caraschi, Nivaldo Schultz
| openaccesspublications.org
Abstract Objective: The aim of this paper is to show the application of the Surface Experiment to a petrochemical industry in the northern region of the state of Rio de Janeiro, Brazil. Theoretical framework: One of the tools provided by statistics for process optimization is the Response Surface Methodology, which has been widely applied in recent years for the study of optimization (Bas & Boyaci, 2007).

Are Soil Physical-Hydraulic Attributes Influenced By Profile Position On The Slope?

|
By Marcos Pereira, Nivaldo Schultz
| openaccesspublications.org
Abstract Objective: This study aimed to evaluate the influence of soil physical-hydraulic attributes in a toposequence at the Federal Rural University of Rio de Janeiro campus, identifying their relationship with erosion susceptibility. Theoretical framework: The research is based on studies on erosive dynamics and soil conservation, considering the influence of relief and physical-hydraulic characteristics on soil formation and degradation.

Soil and Water Losses with Simulated Rainfall Considering Experimental Plots and Rainfall Patterns

|
By Amanda Alves, de Carvalho, Daniel Fonseca, Nivaldo Schultz
| MDPI
4. Discussion 4.1. Precipitation Intensity, Water Use Efficiency, and the Uniformity Coefficient In experimental research planning, knowing the WC of the rainfall simulator is important information. This helps the operator determine the required volume of water to simulate rain in the field, which is dependent on the PI and test duration. Overall, the circular plot had a higher precipitation intensity (PI) as the InfiAsper water jet’s wetting area tended to form a circular spray pattern.
