摘要:
Temperature-controlled pressure regulators are described. An example temperature-controlled pressure regulator described herein includes a regulator body having a process fluid inlet fluidly coupled to a process fluid outlet via a first passageway and a heat transfer medium inlet to be fluidly coupled to a heat transfer medium outlet via a second passageway, where the heat transfer medium inlet is integrally formed with the regulator body. A heat chamber body is removably coupled to the regulator body to form a chamber between the heat transfer medium inlet and the heat transfer medium outlet. At least a portion of the first passageway is disposed within the chamber, and the chamber is to receive a heat transfer medium via the heat transfer medium inlet to provide heat to the process fluid as the process fluid flows through the chamber via the first passageway, which separates the process fluid from the heat transfer medium.

A gate valve, comprising a body (1), a gate element (2), which is movable in the body, transversally with respect to the flow path (3) between at least two positions, i.e. a first position, where the flow path (3) is open, and a second position, where the flow path is closed, and means (4) for moving the gate element (2) between at least said two positions; said gate valve body (1) comprising a first wall element (9) and a second wall element (10) and a space (11) left therebetween for the gate element (2), and an edge part (12), which edge part, when bent, forms a support surface for the first wall element (9) and the second wall element (10) of the gate valve body; in said edge part (12), there is arranged a channel space (13), including at least one opening (14), preferably several openings, which channel space opens into the space (11) left between the first wall element (9) and the second wall element (10) for conducting medium into said space. The edge part (12) is a pipe element, which is arranged between the first wall element (9) and the second wall element (10), and the walls (9, 10) are pressed by clamping means (15, 16) against the edge part (12), so that the edge part is pressed in between the first wall (9) and the second wall (10).
摘要:
The present invention relates to a process for improving the devolatilization of polymer slurry produced in an olefin polymerization reactor. The process is characterized in that it involves an adjustment of the temperature of the interior surface of the flash line for transferring polymer slurry from the polymerization reactor to a downstream processing unit. In particular, in accordance with the present process, the temperature of the interior surface of the flash line is adjusted to a temperature which is equal to or higher than the softening temperature of the polymer passing through said flash line.

A gas-tight shut-off valve (14) for a material charging or discharging lock (10) comprises a valve closing element (26) that is movable relative to a valve seat (22), between a first position, in which the valve closing element (26) and the annular valve seat (22) can be axially pressed together, and a second position, in which the valve closing element (26) is located laterally of the discharge opening (24) in the valve seat (22). A soft sealing means (28) is associated either with the annular valve seat (22) or with the valve closing element (26). The valve (14) further comprises a heat protecting element (30), which is movable between a first position, in which it covers the soft sealing means (28) when the valve closing element (26) is in its second position, and a second position, in which it uncovers the soft sealing means (28).
摘要:
A pressure regulator (10) includes a body (14) having an inlet (20) and a pressure regulating chamber (28). A high pressure fluid circuit (26) extends between the inlet (20) and the pressure regulating chamber (28). The circuit (26) includes at least two longitudinally extending high pressure passages (30,31) in fluid communication with each other. One passage (30) transmits the fluid in a first direction, and the other passage (31) transmits the fluid in a second direction different from the first direction.
摘要:
This invention provides a thermal energy system comprising a heat exchanger for transferring thermal energy between a source and a load, the heat exchanger having a primary side associated with the source, and a secondary side for conducting a fluid associated with the load, wherein the secondary side of the heat exchanger is passively back-flushed upon consumption of a portion of the fluid. Passive back-flushing prevents fouling of the heat exchanger due to sediments, scale, and mineral deposits which may be present in the circulating fluid.
摘要:
A valve (10) for feeding abrasive particulate material to, and removal of particulate material from a pressurized vessel, adapted to operate at temperatures above 500 °C, comprises a valve structure wherein a single shutoff member (14) of generally spherical shape performs both functions of shutoff the particulate material and the gas-tight sealing by means of a resilient inflatable circular seal element (40) which engages the convex side of said shutoff member. Said seal element is inflated and cooled by a pressure regulated and continuously flowing stream of liquid water. The seal element is protected from being damaged at high temperatures by contacting it with the cooled shutoff member when the valve is closed and with a cooled circular extension of the shutoff member when the valve is open.
