Title: Production of methanol
IPC: C07C29/151
Filed: 1976-12-30
Abstract: In the production of methanol from gaseous hydrocarbons having a lower C/H ratio than is stoichiometrically required to produce methanol and comprising the steps of catalytically cracking said hydrocarbons in the presence of water vapor at about 830 DEG to 930 DEG C. and about 5 to 30 bars to produce a synthesis gas consisting essentially of hydrogen and oxides of carbon, and subsequently catalytically converting said synthesis gas of hydrogen and oxides of carbon to methanol at about 230 DEG to 280 DEG C. and about 30 to 150 bars, the improvement which comprises transferring heat from the hot synthesis gas to the hydrocarbon-water vapor mixture flowing through the cracking catalyst thereby providing at least part of the heat required for the catalytic cracking of the hydrocarbons and reducing the consumption of thermal-/energy per unit of methanol produced. Advantageously, heat transfer is effected by passing the hot synthesis gas through a convoluted or corrugated tube embedded in the hydrocarbon cracking catalyst. Gaseous carbon-containing constituents of the methanol synthesis exhaust gas are removed by adsorption, and desorption CO2 may later be removed from the residual methanol synthesis exhaust gas by methanol scrubbing and subsequent stripping, both the desorbed constituents and the CO2 being mixed with the hydrocarbons before they are cracked, whereby the C/H ratio of the hydrocarbon feed is raised and the consumption of the thermal-/energy per unit of methanol produced is reduced.

Patent ES-466218-A1 (ES)
Title: Lead acid storage battery and method of manufacturing same
IPC: H01M4/22
Filed: 1978-01-20
Abstract: Accumulator of the lead acid type which can be activated by addition of electrolyte consists of >=1 assembly of shaped positive and negative plates with insulating separators interposed between adjacent plates. Part of the sulphuric acid used for forming the plates is retained in the accumulator and has a specific gravity of 1.25-1.35g/cc., the amount of acid retained is insufficient to connect the plates during storage. The accumulator includes devices for sealing it against air penetration, but permitting gas produced inside the accumulator to escape. Each positive plate contains >=0.1 cc acid per g. of active material. The strength of the acid retained in the accumulator is high enough to maintain a strongly acid soln. for the plates during storage. Since it is the acid used during formation of the plates, rinsing and drying are avoided. Since the formation of acid has a SG of 1.25-1.35, activation of the battery can be effected with the same strength or weaker acid than that normally used for charging dry accumulators, i.e. 1.26g/cc.

Title: Process for reducing the risks of inflammation and explosion as a result of the decomposition of ethylene under high pressure, and device for carrying out the process.
IPC: B01J3/04
Filed: 1980-04-24
Abstract: The danger of explosion due to decomposition of high-pressure industrial process gases, such as ethylene, is reduced by beginning to cool the decomposition gases with a delay of no more than 25 milliseconds from the onset of flow of the gases out of a high-pressure vessel. The process may be implemented by using apparatus comprising: (1) means containing an inert gas at a pressure P between about 5 and 50 bars and an inert liquid of high heat of vaporization and (2) a valve located upstream of an inert-liquid dispersing-means, of which the opening is operated by a means detecting the opening of a safety means of the high-pressure vessel and operating the working of the dispersing means. The apparatus is useful for the recovery of decomposition gases in order to avoid atmospheric pollution, as well as for reducing the risk of explosion.
Patent ES-8101342-A1 (ES)
Title: Revolution control device for accdc motor operated by ac voltage source
IPC: H02P25/14
Filed: 1980-04-25
Abstract: The rotation-speed regulator is provided with a controlled semiconductor (17) in series with the motor, a threshold-value switch (18) in the control loop of the controlled semiconductor (17), and with an RC element (19), having an adjustable time constant, on the input side of the threshold-value switch. In the case of this regulator, the influence of power-supply voltage fluctuations on the rotation speed of the motor is largely eliminated, so that the motor essentially runs at an unchanged rotation speed in the event of variations in the power-supply voltage. For this purpose, the threshold-value switch (18), which is preferably constructed as a programmable unijunction transistor (20), has a threshold value whose magnitude is controllable. A control circuit (21) changes the threshold value as a function of voltage changes in the AC voltage power supply (15).

Patent ES-8204491-A1 (ES)
Title: Process for drilling underground arcuate paths and installing production casings, conduits, or flow pipes therein
IPC: E21B7/04
Filed: 1981-06-26
Abstract: A directional drill attached to a drill string having periodic concentric collars is advanced in an inverted arcuate path to form a pilot hole underneath an obstacle followed by a larger concentric washover pipe. When the washover pipe reaches the surface on the other side of the obstacle a first reamer is attached to the end of the washover pipe exiting the drilling path, a second reamer of smaller diameter than the first reamer is attached to the other end of the first reamer by means providing for some separation between the two reamers, and a production casing of smaller diameter than the second reamer is attached to the other end of the second reamer with a swivel. The remaining length of the first portion of casing is supported some distance above the ground on rollers located above and beyond the exit point of the pilot hole. The reamers are operated by rotating the washover pipe and simultaneously drawing the washover pipe through the pilot hole. As the reamers are drawn through the pilot hole the first reamer enlarges the hole to a diameter greater than that of the casing. Drilling mud pumped through the washover pipe exits at the reamers to entrain the dislodged earth and the second reamer compacts it to form a bushing around the sides of the enlarged hole to lubricate the passage of the casing. The reaming operation may be performed without the production casing attached to the reamers followed by a second reaming operation with the casing attached in order to complete the installation.
