The present disclosure relates to a vessel for separating, at a pressure of from 10 MPa to 50 MPa, a composition comprising liquid components and gaseous components into a liquid fraction and a gaseous fraction, wherein the separation vessel has a vertically arranged cylindrical shape, has at its top a manhole, which is surrounded by a thickened by a part of the separation vessel wall; and bears at least one bursting disc which is held by a bursting disc holder which is installed pressure-tight within a boring in the thickened part of the separation vessel wall.

The present invention provides a highly effective method of removal of gases from the chemical reactor (01) by use of a suction unit employed near the inlet, outlet or both ends of the chemical reactor. The suction of entrapped air from the reaction mixture helps avoid fluctuation in the temperature or pressure requirement or formation of other by-products in the reaction mixture.

Disclosed herein are systems that include a customized treatment fluid created in an exterior reactor which is delivered into a cased well, then into the heap or pile to open or stimulate new horizontal and vertical fluid pathways or channels thereby creating a second reactor in the interior of the heap or pile. One or more reagents can undergo physical changes, chemical, catalytical, biochemical, and/or biological reactions when added, mixed, and pressurized in the exterior reactor to make the treatment fluid. These mixed and pressurized treatment fluids are introduced into the heap or pile, to change one or more of the physical, biological, microbiological, or chemical conditions of the pile in an internal pressurized second reactor to improve metal recovery or change the target material in the pile.

A method for controlling a synthesis loop for production of a chemical product, such as ammonia or methanol, wherein a feed rate of the loop depends on at least one source of renewable energy, the pressure of the loop and the delivery rate of a makeup compressor and of a circulation compressor are continuously controlled to follow the variable rate of the feed while maintaining the loop pressure within a target deviation from a design loop pressure.
