EXERGY ANALYSIS AND PERFORMANCE STUDY FOR SOUR WATER STRIPPER UNITS, AMINE REGENERATOR UNITS AND A SULPHUR RECOVERY UNIT OF A REFINING PLANT

Exergy analysis and performance study for sour water stripper units, amine regenerator units and a Sulphur recovery unit of a refining plant

Abstract A refining column in the middle east that started its official production in 2020 provides its sour wastewater from all refinery plants click here to two sour water units (SWS1 and SWS2) to strip H2S and NH3.Sour gas from the refinery uses a lean amine solution for gas sweetening to absorb H2S in different absorbers.Rich amine with H2S is

Upregulation of the hypothalamo-neurohypophysial system and activation of vasopressin neurones attenuates hyperalgesia in a neuropathic pain model rat

Abstract Arginine vasopressin (AVP) is a hypothalamic neurosecretory hormone well known as an antidiuretic, and recently reported to be involved in pain modulation.The expression kinetics of AVP and its potential involvement in the descending pain modulation system (DPMS) in neuropathic pain (NP) remains unclear.We investigated AVP expression and i

Malfunction of Vascular Control in Lifestyle-Related Diseases: Oxidative Stress of Angiotensin II-induced Hypertension: Mitogen-Activated Protein Kinases and Blood Pressure Regulation

The candidate mechanisms for maintaining hypertension in a chronically angiotensin II (Ang II)-infused state include direct vasoconstriction of the vasculature, disturbance of renal water/sodium handling, and central/peripheral sympathetic nerve regulation of hemodynamics.The involvement of reactive oxygen species (ROS) has been studied in these pr
